ABSTRACT: Glomus tumours (GT), neoplasms of the glomus body comprise 4.5% of upper limb tumours. Seventy-five per cent of these occur in the hand, and most are subungual (50%). We performed a literature review and retrospective search of histopathologically confirmed GT seen from 1995 to 2009. Fifteen patients were identified, with an average age of 49.6 years. Eight were in the hand, 2 in the upper limb, 2 lower limb and 3 in the ear. Eighty-six per cent presented with pain and 50% underwent radiological investigation. Most diagnoses followed biopsy findings. Surgical excision resulted in a recurrence rate of 13%. The average time to diagnosis was 3.3 years. The average duration of symptoms was 7 to 11 years with an average of 2 to 3 consultations prediagnosis. MRI remains the most useful imaging modality (82 to 90% sensitivity). Excision biopsy is the most common treatment. Greater awareness is needed for quicker diagnosis.

We report the case of a 30-year-old woman who was referred to us for evaluation of a 2-week history of fever, headache, vomiting, bilateral ptosis, and blurred vision. Imaging obtained by the referring institution had identified a sphenoid sinus mass and diffuse meningeal infiltration, which was thought to represent an infective process. We subsequently identified the mass as a metastatic hepatocellular carcinoma (HCC). The patient was placed under palliative care, and she died 1 month later. Metastases to the sphenoid sinus from any primary source are very rare, and they are generally not considered in the radiologic differential diagnosis. HCC is known to metastasize to the lung, lymph nodes, and musculoskeletal system; again, reported cases of metastasis to the sphenoid sinus are rare. Indeed, our review of the English-language literature found only 6 previously reported cases of sinonasal metastasis of a primary HCC. A diagnosis of a sinonasal metastasis is more difficult in a patient who has no previous diagnosis of a primary malignancy. In presenting this case, our aim is to remind readers of this possibility.

Filariasis, a parasitic infection endemic in parts of India, Myanmar, islands of the South Pacific, West and East Africa and Saudi Arabia can be diagnosed from various types of cytopathological specimens. This case documents the detection of filarial infection from hydrocele fluid cytology in a 30-year-old Myanmar migrant worker in Malaysia.

Basaloid Squamous Cell Carcinoma: An Unusual Ball-Valve Laryngeal Obstruction

Tan SH, Hindi KW, Chandran PA, Chong AW

Iran J Otorhinolaryngol, 2015 May;27(80):243-6.

PMID: 26082908

INTRODUCTION: A rare case of basaloid squamous cell carcinoma (BSCC) of the larynx, which has not been previously reported, is described.

CASE REPORT: A 60-year-old man was presented to the Otolaryngology Department with progressive dyspnoea and dysphagia to solids for over a period of 1 week. Direct laryngoscopy revealed a tumour at the laryngeal aspect of the epiglottis, which prolapsed into the laryngeal inlet each time the patient inspired. This resulted in an inspiratory stridor despite adequate glottic opening and normal mobility of the vocal cords.

CONCLUSION: Therefore, in cases where a ball-valve lesion causes intermittent life-threatening airway obstruction, BSCC of the larynx, though rare, must be considered as a differential diagnosis.

Fulltext Synchronous unilateral infiltrating ductal and lobular breast carcinoma

PMID: 23192514

The incidence of synchronous bilateral infiltrating breast cancer has been reported to be 2%. However, synchronous unilateral infiltrating ductal carcinoma and infiltrating lobular carcinoma (ILC) are very rarely reported. We present a woman with palpable ILC who was later found to have synchronous well-circumscribed ductal carcinoma on further imaging. We also discuss the use of diagnostic approaches such as ultrasonography, mammography and histopathology. This case highlights the importance of careful assessment of concurrent lesions in the breast in the presence of an existing carcinoma.

This paper reports an unusual case of a transsphenoidal encephalocele and discusses our experience with a minimally invasive management. To the best of our knowledge, we present the first case of a combined endoscopic transnasal and transoral approach to a transsphenoidal encephalocele in an infant.

Advanced MRI applications and findings of malignant phyllodes tumour: review of two cases

Alhabshi SM, Rahmat K, Abu Hassan H, Westerhout CJ, Chandran PA

Jpn J Radiol, 2013 May;31(5):342-8.

Phyllodes tumour or cystosarcoma phyllodes is a rare stromal breast tumour that is usually benign but on rare occasions can turn malignant. Non-specificity of the imaging features on sonography and mammography makes it difficult to distinguish malignant from benign counterparts solely based on imaging. The final diagnosis is still highly dependent on histopathological assessment. Herein, we describe two cases of malignant phyllodes tumour with emphasis on magnetic resonance (MR) imaging features using advanced MR applications.

Fulltext Gastrointestinal tract metastasis presenting as intussusception in invasive lobular carcinoma of the breast: A case report

Mosiun JA, Idris MSB, Teoh LY, Teh MS, Chandran PA, See MH

Int J Surg Case Rep, 2019;64:109-112.

PMID: 31629292 DOI: 10.1016/j.ijscr.2019.10.003

INTRODUCTION: Breast cancer metastasis to the gastrointestinal (GI) tract is rare and occurs more frequently in invasive lobular carcinoma. Patients may be asymptomatic or present with variable vague symptoms that may be mistakenly attributed to side effects of chemotherapy or other benign GI diseases. Treatment follows the principles of systemic disease and includes hormonal therapy, chemotherapy and signal transduction inhibitors, with surgical intervention indicated for complications such as obstruction, perforation and hemorrhage.

PRESENTATION OF CASE: We present the case of a female patient with a history of invasive lobular breast carcinoma who had undergone mastectomy and axillary dissection, followed by chemoradiotherapy. Over the next nine years, she developed ovarian and bone metastases for which appropriate treatment was provided. A right iliac fossa mass was discovered during routine clinic review, though she remained asymptomatic. Computed tomography scan showed ileocecal intussusception. Histopathological examination of the right hemicolectomy specimen following emergency surgery confirmed metastatic invasive lobular carcinoma to the GI tract.

DISCUSSION: GI tract metastasis may present 30 years after the primary breast cancer. Up to 20% of patients may be asymptomatic as shown by Montagna et al. When present, symptoms are commonly non-specific and vague. Histological diagnosis is challenging. GI metastasis typically appears as intramural infiltration of the bowel wall by small cells arranged in cords.

CONCLUSION: It is important to maintain a suspicion for GI tract metastasis in breast cancer patients who present with abdominal mass or GI symptoms, as this aids in prompt institution of accurate and appropriate management.

Fulltext Pleomorphic adenoma of the frontal sinus masquerading as a mucocele

Chew YK, Brito-Mutunayagam S, Chong AW, Prepageran N, Chandran PA, Khairuzzana B, et al.

Ear Nose Throat J, 2015 Dec;94(12):E4-6.

PMID: 26670764 DOI: 10.1177/014556131509401202

Pleomorphic adenoma is the most common type of benign salivary gland tumor. It can also be found in the larynx, ear, neck, and nasal septum. It is rarely found in the maxillary sinus, and it has never been reported in the frontal sinus. We report a case of pleomorphic adenoma of the frontal sinus that masqueraded as a mucocele. We discuss the clinical presentation, diagnosis, and treatment of this patient, and we review the literature.

Fulltext Lymphocytic mastitis mimicking breast carcinoma, radiology and pathology correlation: review of two cases

Alhabshi SM, Rahmat K, Westerhout CJ, Md Latar NH, Chandran PA, Aziz S

PMID: 23966831 MyJurnal

Lymphocytic mastitis, or diabetic mastopathy, is an unusual finding in early-onset and long-standing diabetes. It can presents as a non-tender or tender palpable breast mass. Mammogram and ultrasound frequently demonstrate findings suspicious of malignancy, thus biopsy and histological confirmation is usually required. We reviewed two cases of lymphocytic mastitis with characteristics findings on mammogram, ultrasound, and histopathology. Diagnoses were confirmed with excision biopsy.

Fulltext Shearwave Elastography Increases Diagnostic Accuracy in Characterization of Breast Lesions

Ng WL, Rahmat K, Fadzli F, Rozalli FI, Mohd-Shah MN, Chandran PA, et al.

Medicine (Baltimore), 2016 Mar;95(12):e3146.

PMID: 27015196 DOI: 10.1097/MD.0000000000003146

The purpose of this study was to investigate the diagnostic efficacy of shearwave elastography (SWE) in differentiating between benign and malignant breast lesions.One hundred and fifty-nine lesions were assessed using B-mode ultrasound (US) and SWE parameters were recorded (Emax, Emean, Emin, Eratio, SD). SWE measurements were then correlated with histopathological diagnosis.The final sample contained 85 benign and 74 malignant lesions. The maximum stiffness (Emax) with a cutoff point of ≥ 56.0 kPa (based on ROC curves) provided sensitivity of 100.0%, specificity of 97.6%, positive predictive value (PPV) of 97.4%, and negative predictive value (NPV) of 100% in detecting malignant lesions. A cutoff of ≥80 kPa managed to downgrade 95.5% of the Breast Imaging-Reporting and Data System (BI-RADS) 4a lesions to BI-RADS 3, negating the need for biopsy. Using a combination of BI-RADS and SWE, the authors managed to improve the PPV from 2.3% to 50% in BI-RADS 4a lesions.SWE of the breast provides highly specific and sensitive quantitative values that are beneficial in the characterization of breast lesions. Our results showed that Emax is the most accurate value for differentiating benign from malignant lesions.
