    Hepatic angiosarcoma is a rare primary mesenchymal malignancy. Prognosis is poor and mortality occurs early. The diagnosis is challenging. Our case was an asymptomatic 70 year-old man referred, with incidental ultrasonography finding of multiple liver nodules. Diagnostic laparoscopic liver biopsy and the histopathological examination reported a haemangioma. Six months later, he became symptomatic and his health condition deteriorated rapidly.

    Data from the National Cancer Registry of Malaysia for 2004 provide an age-standardised incidence rate (ASR) of 46.2 per 100,000 women. This means that approximately 1 in 20 women in the country develop breast cancer in their lifetime. However, the rate differs between the three main races, the Malays, Chinese and Indians. The age standardized incidence in Chinese is the highest, with 59.7 per 100,000, followed by the Indians at 55.8 per 100,000. The Malays have the lowest incidence of 33.9 per 100,000. This translates into 1 in 16 Chinese, 1 in 16 Indian and 1 in 28 Malay women developing breast cancer at some stage in their lives. The commonest age at presentation is between 40-49 years, with just over 50% of the cases under the age of 50 years, 16.8% below 40, and 2% under 30. Some 55.7% of all cases were found to be ER positive. The commonest presenting symptom was a lump in the breast in over 90% of cases, generally felt by the woman herself. The mean size of the lump was 4.2 cm, and on average, the women waited 3 months before seeking medical attention. Over the 12-year period from 1993 to 2004, about 60-70% of women presented with early stage (Stages 1-2) while 30-40% presented with late breast cancer (Stages 3-4). Especially Malays present at later stages and with larger tumours. Consequently their survival is worse than with Chinese and Indian women. The challenge in Malaysia is to be able to provide a comprehensive service in the diagnosis and treatment of breast cancer, and this requires training of a team of health professionals dedicated to breast health, such as breast surgeons, radiologists specializing in breast imaging, breast pathologists, plastic surgeons specializing in breast reconstruction, medical and radiation oncologists, psycho-oncologists, counselors, and breast nurses. Advocacy can play a role here in galvanizing the political will to meet this challenge.

    Tumors are generally difficult to detect in Magnetic Resonance (MR) images as they can be of varying intensities and do not appear as clear structures on these images. This difficulty is more prominent in MR Cholangiopancreatography (MRCP), which is the MR technology using a special sequence of T2-weighted imaging to identify the biliary tract, pancreatic duct, and gallbladder in the liver region, as MRCP images are more noisy in nature and are acquired for a more focused area with too much flexibility in position orientation for convenient computer-aided diagnosis. Based on the principle that the tumor mass manifests itself as blockage of the biliary tree structure, this paper introduces a technique that uses a region growing algorithm to identify discontinuities in the biliary tree as a means to preliminary detection of a possible tumor, in a fashion similar to the visual observation used by most radiologists in making their preliminary diagnosis. Through the use of appropriate image normalization, watershed segmentation, thresholding, rule-based region growing, and region analysis, the proposed technique is shown in this paper to be successful in identifying MRCP images with liver carcinoma from those with normal liver. Acquisition standardization, interactive image selection, and optimum image orientation will further enhance the accuracy of this proposed scheme for use in aiding clinical diagnosis at medical institutions.

    Inverted papilloma is the most common benign tumor of nose and paranasal sinuses arising from lateral nasal wall and middle meatus. Histologically these tumors are composed of epithelial nests that are inverted, exophytic and cylindrical. Here we describe a clinical case of nasal cylindrical cell papilloma, which was treated by endoscopic excision.

    Tumour markers are substances related to the presence or progress of a tumour. An ideal tumour marker is (1) detectable only when malignancy is present, (2) specific for the type and site of malignancy, (3) correlates with the amount of malignant tissue present and (4) responds rapidly to a change in tumour size. At present, no tumour marker fulfills all of the above criteria. The first part of the review discusses the clinical usefulness of the commonly requested serum tumour markers, namely, prostate-specific antigen (PSA), CA 19-9, carcinoembryonic antigen (CEA), CA 125, CA 15-3, human chorionic gonadotrophin (hCG) and alpha-foetoprotein (AFP). It is hoped that this review article will decrease the abuse and misuse of these commonly requested serum tumour markers. The second part of the review discusses the clinical usefulness of catecholamines and their metabolites, calcitonin, thyroglobulin, parathyroid hormone, prolactin, adrenocorticotrophic hormone, oestrogen and progesterone receptors, p53, HER-2/c-erbB2, BRCA1 and BRCA2.

    Leiomyomas are benign soft tissue swellings of smooth muscle origin, most commonly found in the uterus. Extra uterine leiomyomas presenting as an abdominal mass is often a diagnostic challenge as such occurrence is rare. We present a rare case of primary abdominal wall leiomyoma, and highlight the importance of laparoscopic approach in the diagnosis and treatment of such tumour.

    Hepatocellular carcinoma (HCC) is one of the commonest cancers in Asian males. In Malaysia, it is one of the ten most common cancers amongst the male population. Most of our patients with HCC present to us rather late and almost all die within 4 months of diagnosis. HCC occurs more commonly in patients with cirrhosis associated with hepatitis B and C infections. Screening for HCC can lead to early detection of small tumours (< 5 cm) that are more amenable to surgical resection, resulting in improved survival rates. The average 5-year survival rate for those who have undergone surgical resection is 68% (range, 22-73%). Better results are obtained with the smaller tumours (< 2 cm in diameter). Patients with chronic hepatitis B and C infection especially those who are > 45 years of age, who have concomitant cirrhosis or have a family history of HCC should be examined every 3-6 months with periodic serum alpha-fetoprotein (AFP) measurements and abdominal ultrasound examinations. Abdominal ultrasound is useful in the detection of small tumours. While mass screening for HCC is not cost-effective in countries of low incidence of HCC, screening of high risk groups may be justified in countries with a high endemicity of HBV infection. Screening for HCC in Japan, Taiwan and China appears to yield better results than those in the West. Nonetheless, primary prevention with mass hepatitis B vaccination and blood donor screening for anti-HCV is expected to make a much greater impact in the control of HCC in the years to come.

    Primary non-Hodgkin's lymphoma of the brain is rare. Majority of the lesions are intraaxial, multicentric and involve the leptomeninges. We report a case of malignant primary non-Hodgkin's lymphoma arising from the cranial vault. Computed tomography of the brain showed an extraaxial lesion in the right parietal region mimicking a meningioma.

    A rare case of hydatidiform mole occurring 7 consecutive times in a Chinese woman is presented. She was first seen in 1979 at the age of 23 years, with a molar pregnancy and subsequently had 6 consecutive moles, the last being in July, 1986; at this visit the patient and her husband were very depressed, and convinced that a normal pregnancy was unlikely and requested a hysterectomy. They were warned earlier several times, of the possible long-term consequences of a recurrent mole and that their chance of having a normal baby was very remote. A total hysterectomy was performed at her last presentation as the patient requested one, instead of dilatation and curettage for a persistently high HCG and bulky uterus following suction evacuation. Histology revealed an invasive mole. The beta HCG level was less than 4IU/l by the end of September, 1986 and she is still being followed-up.

    A case is presented to illustrate the difficulties
    encountered in the clinical diagnosis of an intraocular mass. The fundus was not visible ophthalmoscopically because of opaque media. The anterior surface of the iris showed three discrete hyperpigmented nodular patches. Ultrasound showed an intraocular mass occupying half the posterior segment. The eye did not have useful vision and was enucleated after a clinical diagnosis of malignant melanoma of the choroid was made. The eye did not contain a melanoma but an organised blood clot after an extensive vitreous haemorrhage because of systemic hypertension.

    Leiomyoma of the caecum is a rare tumour. While leiomyomata are known to arise from any part of the large bowel, caecum is a rare site. The largest series to date is that of Mackenzie" who reviewed 37 cases of myomatous tumours of the colon, two of which were complicated by perforation. More recently, Swerdlow" reported another case of a perforated caecal leiomyoma. We now report a patient who was operated at the stage of abscess formation without perforation.
