ABSTRACT
Alpha-fetoprotein has emerged as a useful diagnostic tool for hepatic tumour and tumours of germ cell origin. However, isolated case reports of association of this tumour marker with tumours of the lung and non-germ cell tumours of the ovary are reported. We present a case of a Rhabdomyosarcoma, a generally non-secretory tumour that showed raised levels of AFP in serum and reacted positively for the same in a PAP technique for AFP. Cross striations were visible in many cells on II & E stained sections.

Hepatocellular carcinoma commonly invades the portal vein but is rarely seen in the bile duct. When seen, a minor intraductal component usually accompanies a prominent hepatic involvement. We report a case of hepatocellular carcinoma that entirely involved the common bile duct, the hepatic involvement was undiscernible at operation or ultrasonography. The patient had obstructive jaundice both at first presentation and at recurrence. The liver was normal at both explorations. The elevated AFP levels returned to normal after second resection. The diagnosis was confirmed by electron microscopy.

Kidney involvement by Non-Hodgkin's lymphoma is very common microscopically but rarely a cause of uraemia even when the parenchymatous involvement is considerable. Renal failure in cases of lymphoma is secondary to ureteral obstruction, hypercalcaemia, urate nephropathy, gammopathy or immunologically mediated nephrosis. This is a case where the patient presented to the ophthalmic O.P.D. with blurring of vision and admitted with full blown uraemia. He could not be saved and at autopsy, a gastrointestinal lymphoma was found in the caecum. His uraemia was due to massive parenchymatous involvement of the kidney, there being no ureteral obstruction, hypercalcaemia, urate or immunologically mediated nephropathy. Very few cases are reported in literature with such a presentation.
