The most common primary malignant renal tumor is renal cell carcinoma (RCC), which accounts for 3% of all adult malignancies. Bellini duct carcinoma or collecting duct carcinoma is an unusual rare variant of RCC. This histologically distinct tumor is very rare, with less than 100 cases reported in the literature, and accounts for approximately 1% of all malignant renal epithelial tumors. We report two cases of collecting duct carcinoma and highlight the rarity of these tumors and their similarity to RCC.

Cronkhite-Canada syndrome (CCS) is an extremely rare non-inherited condition characterized by gastrointestinal hamartomatous polyposis, alopecia, onychodystrophy, hyperpigmentation, weight loss and diarrhoea. The aetiology is probably autoimmune and diagnosis is based on history, physical examination, endoscopic findings of gastrointestinal polyposis, and histology. The disease is very rare; approximately 450 cases of CCS have been reported worldwide. The author reports a case of CCS in an elderly Indian male. © 2015, Journal of Clinical and Diagnostic Research.

A 60-year-old patient suffering from easy fatigability was noted to have high total but normal conjugated bilirubin level though serum colour was pale. On further investigation the patient was found to be suffering from multiple myeloma and gamma globulin was possibly interfering with total bilirubin estimation. © 2012 Association of Clinical Biochemists of India.

Although serum potassium levels are usually subnormal in Thyrotoxic Periodic Paralysis (TPP), but in exceptionally rare circumstances, it may be normal leading to the entity called normokalemic TPP. The diagnosis of normokalemic TPP is more often overlooked and/or delayed due to lack of awareness among the physicians and associated mild symptoms of hyperthyroidism. Here, the author describes the case of a 27-year-old male with newly diagnosed but untreated Grave’s disease and TPP who was normokalemic during the acute phase of paralysis. Hypokalemia was documented only after resolution of paralytic attacks during subsequent days of admission. The importance of the case report is to highlight upon the fact that TPP should always be considered in an “previously asymptomatic” young Asian individual with acute paralysis with or without hypokalemia, and thyroid function and serial potassium values should be evaluated for diagnosing the usual hypokalemic type or the more rarer variant normokalemic TPP. This case report also deserves mention as the patient of TPP had a notable feature of having preserved reflexes in the face of hypokalemia. © 2015, Journal of Clinical and Diagnostic Research.

Amoebic liver abscess is the most frequent extra-intestinal manifestation of Entamoeba histolytica infection. Immunosuppression is known to predispose to amoebic liver abscess. Although amoebic liver abscess is seen more commonly in patients of Human-Immunodeficiency virus (HIV), first presentation of HIV sero-positive patient as multiple liver abscess is quite uncommon.The author reports an unusual case of multiple liver abscesses in an HIV seropositive patient. This middle aged male with history of multiple unprotected sexual encounters presented with spasmodic abdominal pain, fever, diarrhoea and weight loss along with generalised ill-health and painful liver enlargement. HIV-1 serology was found to be reactive. Imaging revealed an enlarged liver with multiple, irregular, hypoechoic foci characteristic of abscesses. Amoebic aetiology was later confirmed by percutaneous aspiration and microscopy. Administration of appropriate chemotherapeutics along with institution of antiretroviral therapy led to both clinical resolution as well as disappearance of lesions. © 2015, Journal of Clinical and Diagnostic Research.
