Pheochromocytoma Presenting with Adrenal Necrosis due to Spontaneous Hemorrhage: A Case Report.

Pheochromocytomas are seldom and vascular neuroendocrine tumors-secreting catecholamines. They may be adrenal or extra-adrenal in origin. Symptoms are due to periodic catecholamine discharge into the vasculature, the mass effect of the lesion or adrenal insufficiency. There are various etiologies causing adrenal hemorrhage of which a mass lesion is one of the rarest. Adrenal hemorrhage occurring during pheochromocytoma is an extremely rare but life-threatening complication especially when it extends to the retroperitoneum. Case reports of adrenal hemorrhage associated with a mass lesion are not frequent in the literature. We report a case of adrenal hemorrhage causing necrosis of the mass which was biochemically documented to be pheochromocytoma and fully recovered after surgery.

Suture granuloma after orchiectomy: sonography, doppler and elastography features

ABSTRACTSuture granuloma is a mass forming benign lesion that develops at the site of surgery as a foreign body reaction to non-absorbable suture material. We present a case of suture granuloma that developed at the inguinal region after orchiectomy, and define the sonography, color Doppler sonography and real-time ultrasound elastography findings in correlation with the histopathological findings.

Fatal disseminated mucormycosis in a patient with mantle cell non-hodgkin's lymphoma: an autopsy case

A patient with mantle cell non-Hodgkin's lymphoma presented herself with fever, nausea, right upper quadrant pain on the 7th day of R-CHOP chemotherapy. After hospitalization with the suspicion of acute cholecystitis, she received antibiotherapy with G-CSF because of emerging neutropenia at the 10th day of chemotherapy. Abdominal computed tomography revealed small infarcts in the spleen and kidneys. The echymotic lesion which developed on her right lateral malleolus, became bullous in the following days and treated as ecthyma gangrenosum. Altough the patient was afebrile with a normal neutrophil count on the third day of antibiotherapy, she developed acute renal failure and deteriorated rapidly. The patient underwent hemodialysis but expired on the 10th day of hospitalization. Post mortem autopsy findings showed ischemic infarction and necrosis of parenchyma due to mycotic thrombosis of arteries and veins of many organs (heart, lung, diaphgram, kidneys, spleen, gut mucosa) as well as invasion of vessel walls and parenchyma by mucor. We reviewed mucormycosis in the light of this case.
