We present a patient of tuberous sclerosis complex with bilateral renal angiomyolipoma and hepatic angiomyolipoma with spontaneous retroperitoneal hemorrhage from right angiomyolipoma (Wunderlich's syndrome). Nephron preserving approach was tried but the right kidney could not be salvaged. Hepatic angiomyolipoma was managed conservatively. Wunderlich's syndrome has been found in around 10% of c...

Isolated pulmonary xanthomatous nodules which present as coin lesions are uncommon. The gross resemblance of the lesion to a neoplasm and the peculiar microscopic characteristics, especially as seen in frozen sections, may lead to diagnostic errors. The following two cases are similar to those classified as xanthomas and reported by Scott, Morrow, and Payne’ in 1948 and by Ford, Thompson, and 2...

A teratoma, by definition, is a true tumour or neoplasm composed of multiple tissues of kinds foreign to the part in which it arises. In a series of 82 cases Willis (1953) quotes the following sites of origin: ovary, 50, and testes 19, the remainder being epididymal, retroperitoneal, pre-sacral, anterior mediastinal, intrapericardial and cerebral. A careful search of the literature failed to re...

The operative treatment of chronic contained rupture of a saccular abdominal aortic aneurysm (AAA) with retroperitoneal haematoma is reported. A 62-year-old man presented with a painless abdominal mass and intermittent claudication. He had an episode of severe abdominal pain about 2 years before admission. A giant retroperitoneal neoplasm was initially suspected, based on computed tomography. H...

Extramedullary plasmacytoma (EMP) is an uncommon plasma cell neoplasm results from plasma cell proliferation and consists of monoclonal plasmacytic infiltration, without bone marrow involvement and any other systemic characteristics of multiple myeloma. EMP accounts for 3% of all plasma cell neoplasms and approximately 80% to 90% of EMP involve submucosa of the upper aerodigestive, while scrota...

We are presenting a rare case of a spontaneous extensive perirenal hematoma caused by ruptured renal adenocarcinoma in a patient who was on warfarin therapy because she had atrial fibrillation and three myocardial infarctions. A 77-year-old woman was admitted to our department with acute right flank pain and hemorrhagic shock. The anamnestic data revealed no trauma and hematuria. Abdominal ultr...

Retroperitoneal liposarcoma is a rare neoplasm that often involves other organs and major blood vessels. Complete surgical resection with negative margins is the only potential curative treatment. Here, we report the case of a patient with a large retroperitoneum liposarcoma that was removed by resection of the descending abdominal aorta and infrahepatic inferior vena cava, right nephrectomy an...
