This is a review of the positive biopsy rate of nonpalpable breast lesions detected on mammography. The histology of 130 hookwire excision biopsy from 1990 to 1995 and the cytology of 39 stereotactic fine needle aspiration cytology in 1995 were reviewed. The yearly positive biopsy rate of each procedure was determined. In 1990, the positive biopsy rate for hookwire excision biopsy was 15%, in 1991 20%, in 1992 11%, in 1993 17%, in 1994 33% and in 1995 39%. In 1995, the positive biopsy rate for stereotactic fine needle aspiration cytology was 21%. The positive biopsy rate for hookwire excision biopsy had improved from 15% in 1990 to 39% in 1995.

The main objective of this study is to illustrate the role of ductography in the management of nipple discharge. Thirty-six patients had ductography for the investigation of blood-stained or serous nipple discharge. The ductogram findings were reviewed. Ductography showed an intraductal lesion in 13 patients, duct ectasia in 16 and normal ducts in 7. Fourteen patients had surgery. Eight had preoperative ductography using a mixture of methylene blue and contrast media. Histology revealed 5 cases of duct papilloma, 2 cases of epithelial hyperplasia, 4 cases of fibrocystic change and 3 cases of duct ectasia. Twenty had follow-up without surgery and of these, the nipple discharge ceased in 11 patients. Two patients did not come for follow-up. Ductography has a significant role in the management of nipple discharge. Firstly, surgery might be averted in patients with normal ducts or duct ectasia on ductography. Secondly, intraductal methylene blue will demonstrate the abnormal ductal system to the surgeon and allow for a less radical surgery.
Plasma cell granuloma of the breast is an extremely rare condition. Only one other case has been reported in the literature. We report here the second case of plasma cell granuloma of the breast. After the initial excision, the lesion recurred in both breasts after 5 months.
Benign cystic or solid lumps frequently occur in the breasts of young women, and consequently can also be seen during pregnancy and lactation. Simple cysts do not increase the risk of malignancy. The current management is routine follow-up. Complex cysts are thick walled or contain a mass, and should be followed by a US-guided biopsy and then treated similar to any non-gravid, non-lactating patient.Galactoceles can be detected during the last trimester of pregnancy and during or after stopping lactation. Aspiration can be done to confirm the content. Co-existence of galactocele and malignancy is extremely rare, and the key is to follow up until it resolves.Fibroadenoma is the most frequent lesion found during pregnancy and lactation. Management is usually conservative after triple assessment. Surgery is usually not recommended in pregnant and lactating women unless rapid increase in size occurs or there is discordance in the triple assessment.Lactating adenomas are sometimes interpreted as a variant of fibroadenoma . They can naturally disappear at the end of pregnancy or lactation. Management is usually conservative, and an excisional biopsy is only mandated if it is rapidly enlarging or if there is discordance in the triple assessment.Gestational gigantomastia is a rare condition consisting of diffuse severe hypertrophy of both breasts during pregnancy . Mastectomy and reconstruction may rarely be required in such cases.
A patient with a solitary intracranial cryptococcoma of the occipital lobe of the brain and a concomitant granuloma of similar aetiology in the breast is reported. Despite resistance of the causative fungus to 5-fluorocytosine in vitro, the patient responded well to radical excisional surgery and therapy with 5-fluorocytosine.

Phyllodes tumour (PT) of the breast is firstly described in literature as early as 1838. This article reports the youngest recorded case of giant complicated PT and the role of toilet mastectomy as a salvage surgery. A 19-year-old lady presented with a gigantic lump of the left breast for 6 months which was rapidly growing (20 x 20 cm) and complicated with a foul-smelling blackish discoloration of the breast skin and tissues. Toilet mastectomy was performed as a result. The specimen weighed 4.0 kg with histopathological report of the tumor being borderline phyllodes. Herein, we describe a case of PT, who presented with breast necrosis and we discuss its medico-social aspect of it.
Epidermal inclusion cyst (EIC) arising from the breast is an uncommon benign condition. We report two cases of enlarging EIC of the breast in two women in their forties. The diagnosis of this condition may not be straightforward with imaging alone if an EIC presents as an enlarging lump in the breast and mimics a benign breast lesion, most commonly a fibroadenoma or malignant lesion with benign imaging features. Excision is usually recommended for a definite histopathological diagnosis and for the prevention of potential risks of malignant transformation. Asymptomatic stable lesions do not require treatment; biopsy is unnecessary, and follow-up imaging suffices if typical sonographic and clinical findings are found.

Seventy-eight symptomatic females without palpable breast lumps were subjected to bilateral four quadrant fine needle aspiration cytology. Cytological evidence of an epithelial proliferative lesion was seen in 44 of these cases. Based on the cytological evidence of proliferation, the site for open biopsy was determined. Histopathological study of the breast biopsies in these patients showed proliferative disease without atypia (PDWA) in 40 cases, atypical ductal hyperplasia (ADH) in two, atypical lobular hyperplasia (ALH) in one and ADH with ALH in one case. Cytology was thus useful in establishing the presence of proliferative activity, commenting on the extent of proliferation, and thereby roughly mapping out the area of the breast most suitable for biopsy. On cytological grounds, it was not possible to distinguish the atypical hyperplastic lesions from the proliferative diseases without atypia.
A 60 year old woman with chronic duodenal ulcer not responding to Cimetidine, was changed to Ranitidine. She had symptomatic improvement, but had bilateral breast engorgement and tenderness for which treatment was discontinued. A therapeutic trial on a second occasion had the same side effect which came on more rapidly and quickly. This complication in such severe form and recurrence on rechallenge requiring withdrawal of drug was observed for the first time with any H2 receptor antagonist.

Breast hamartoma is an uncommon poorly recognised benign breast neoplasm. Hamartoma displaying marked smooth muscle components known as myoid hamartoma of the breast is a much rarer entity. We present a case of myoid hamartoma of breast with chondroid differentiation in a 46-year-old woman. The painless breast lump was circumscribed and mammography showed a well-encapsulated large, dense mass with no calcification. Core needle biopsy was reported as fibroadenoma. The lesion was excised. Microscopically, it composed of many groups of mammary glandular components with dense fibrous stroma, adipose tissue and marked groups of smooth muscle fibres. Foci of chondroid differentiation were noted in the lesion. The smooth muscle cells showed strong and diffuse immunoreactivity for vimentin, myogloblin, alpha-smooth muscle actin, desmin and CD34 and failed to express pan-cytokeratin or S100 protein. The ducts lined by epithelial cells were reactive to pan-cytokeratin while the myoepithelial cells were reactive to S100 protein. The various immuno-histochemical staining as well as the cyto-histological changes encountered in myoid hamartomas are discussed with clinical, radiological and pathological correlation to differentiate it from other benign and malignant breast lesions.

Although most anatomical pathologists have encountered breast lesions with the composite histological features of fibroadenoma (FA) and fibrocystic change (FC), referred to as fibroadenomatosis or fibroadenomatoid mastopathy (FAM), little is known about its prevalence or clinico-pathological significance. In a retrospective histological review of 400 consecutive breast lesions, among both East and West Malaysians, coded either as FA or FC in the files of the Department of Pathology, University of Malaya, we found 45 (11.3%) cases of FAM. Typically, FAM lesions showed fibroadenomatoid foci in a background of fibrocystic change. The finding of FAM among lesions coded as FC was higher (18.5%) than among FA (4%). The mean age of patients with FAM (32.1 years) was similar to FC (35.1 years) but significantly older than that of FA (26.1 years). The notion that FA and FC are lesions at two ends of a spectrum of growth disorder of breast related to oestrogen-progesterone interplay, and that FAM occupies a position intermediate between the two, may explain its morphological and age patterns, but remains speculative. It is hoped that increasing awareness of this condition will lead to better understanding of breast pathophysiology. Nevertheless, until its biological nature, histogenesis and malignant potential are more clearly understood, defining FAM as a distinct form of breast disease may not be meaningful to patient management.

The aim of this study is to assess tissue and serum prostate-specific antigen (PSA) in breast lesions; to compare tissue PSA with serum PSA; to compare tissue PSA in benign and malignant lesions and to compare PSA with known prognostic factors in breast carcinoma. Tissue PSA immunoreactivity in twenty women with breast carcinoma was compared with PSA in twenty-three women with benign breast lesions. Tissue PSA was also compared with known prognostic indicators such as tumour size, axillary nodal status, histological type, histological grade, oestrogen receptor status, progesterone receptor status and c-erbB-2 oncoprotein over-expression. Serum free PSAlevels from these women were measured pre- and post-operatively and an attempt was made to correlate serum PSA with tissue PSA expression. 40% and 43% of malignant and benign breast lesions respectively showed tissue PSA immunoreactivity. No significant difference was observed in the tissue PSA expression between these two groups as also between tissue PSA and known prognostic indicators. As serum PSA levels were below the detection limit (< 0.004 ng/ml) in all except two benign cases, no statistical evaluation was done for the latter. Tissue PSA expression did not correlate with other prognostic markers and detectable serum PSA levels were present in too few cases for statistical analysis. Although no definitive conclusion is possible in this preliminary study regarding the role of PSA in breast disease, it stimulates interest in further research in this direction.

X-ray microradiography of surgically excised breast specimens offers the possibility of morphological characterization of calcifications. When combined with digital imaging techniques there exists added potential for obtaining valuable basic quantitative morphometric information regarding differences between microcalcifications in tissues exhibiting evidence of fibrocystic change, benign and malignant tumours. A total of 157 excised breast specimens from 84 patients were microradiographed using a Softex Super Soft X-ray unit and Kodak AA high resolution industrial film. A Quantimet 570C image analysis system was used to digitize and analyse the microradiographs. Of the 157 microradiographs, 51 (from 30 patients) revealed microcalcification clusters. The existence of significant differences between the three identified categories of tissue were indicated by clustering parameters. These included the number of particles per cluster, area of clusters, maximum distance to nearest neighbour, and geometric mean distance to nearest neighbour. The distribution pattern index (DPI), another of the clustering parameters used in this study, has been observed to be a particularly powerful discriminator. The value for fibrocystic change was found to be significantly smaller (0.514) than that for benign tumour (0.796) whilst that for benign tumour was observed to be significantly larger than that for malignant tumour (0.604) at a p-value of less than 0.05 (Kruskal-Wallis one-way analysis of variance).

To evaluate the clinical and imaging findings of papillary breast neoplasm and review the pathologic correlation at a tertiary center.Retrospective study of patients diagnosed with benign and malignant papillary lesions between 2008 to 2018. 147 patients were identified with histology diagnosis of papillary lesions. The clinical, imaging, and pathological characteristics were reviewed.Patient cohort included 147 women diagnosed with papillary lesions (mean age at diagnosis 53.8 years) and were divided into 3 histology groups (benign, atypical, and malignant). Common clinical presentations were breast lump (n = 60) and nipple discharge (n = 29), 48 patients were asymptomatic.Only 37 were detected as a mass lesion on mammogram. The presence of mass lesion on mammogram was the most common feature in all 3 papillary lesion groups, and with the presence of asymmetric density, were the 2 mammographic features significantly associated (P

Breast cancer is becoming more important in Asia since it affect the younger age group. Question arises whether it is safe for breast lesions to be left in-situ if all the elements in triple assessment are benign. The aim of this study is to audit all the excision biopsies of breast lumps done in the University Malaya Medical Centre (UMMC), to review the association of age with the type of pathological finding and to evaluate the rate of carcinoma in these biopsies.
A Mondor’s disease is a rare, benign and self-limiting condition. It is due to thrombophlebitis of the superficial veins of the breast and chest wall. It usually occurs in middle-aged women who present with a palpable cordlike structure, often painful in the acute phase. The aetiology is unknown, and may be related to trauma, surgery, infection or tight clothing. The finding of a superficial vessel seen as a linear opacity on mammography and a tubular structure on ultrasound is typical. An intra-luminal thrombus may be seen on ultrasound, and there may be absent flow on Doppler imaging. Conservative treatment is usually instituted, although surgery may be indicated in certain circumstances.
Breast lesions are rare prepubescents. The majority of breast lesions in this age group are benign. The most common of these rare lesions is juvenile fibroadenoma, which accounts for only 0.5% of all fibroadenomas. It is uncommon to have a palpable lesion in juveniles as very small lesions show obvious asymmetry. Fibroadenomas can grow to a large size, and surgical intervention is cosmetically challenging, especially in achieving symmetry in a developing breast. A 12-year-old girl presented with right breast swelling associated with tenderness. The mass had initially been small on self-discovery 1 year previously and grew with time. There was no overlying skin changes or any significant risk factors for breast malignancy. Triple assessment showed features of fibroadenoma, but we were unable to rule out a phyllodes tumor. She subsequently underwent excision biopsy of the right breast lesion for symptomatic control and histopathology examination (HPE) of the lesion. The HPE report confirmed the diagnosis of fibroadenoma. The patient recovered well postoperatively with no complications. Juvenile breast lesions are rare, and it is a challenge to provide an adolescent with the best treatment in terms of clinical and psychological care. A surgical approach requires meticulous planning to ensure a fine balance between adequate resection and the best cosmetic outcome for a developing breast.
Lactiferous or milk fistula is a tract between the skin and lactiferous duct. Chronic lactiferous duct is uncommon and generally formed during lactating period. It commonly result from complication of the surgical intervention, such as excision biopsy of breast mass or incision and drainage (I&D) for breast abscess. We reported a case of chronic lactiferous fistula secondary to previous I&D for breast abscess in 31 year old lactating woman.
Diabetic mastopathy is a rare fibroinflammatory breast disease characterized by lymphocytic lobulitis, ductitis, and perivasculitis with stromal fibrosis. This lesion often presents as a discretely palpable uni- or bilateral mass in long-standing type I diabetes and other autoimmune diseases. We report a case of insulin-dependent diabetic mastopathy, which presented clinically as an indeterminate breast lump suspicious for malignancy. The patient is a 36-year-old woman who had type 1 insulin-dependent diabetes mellitus. Mammography and ultrasonography raised a suspicion of malignancy, and an excisional biopsy was performed. A previous biopsy had shown no evidence of malignancy. Histopathological examination now showed dense keloid-like stromal fibrosis with epithelioid-like and spindly myofibroblasts and a characteristic lymphocytic infiltration around blood vessels in and around lobules and ducts, features consistent with diabetic mastopathy. The literature is briefly reviewed.
