- Malignant deciduoid mesothelioma is a rare malignant neoplasm occurring in the peritoneum of young women. We report a case of malignant deciduoid mesothelioma that occurred in the omentum of a 47-year-old woman. The patient had never exposed to asbestos and had no history of cesarean section. The lesions were multiple infiltrative nodules affected the peritoneal cavity, omentum, and surface of the uterus with both ovaries. Microscopically, the nodules were composed of mesothelial cells similar to decidual cells

Abstract

- Malignant fibrous histiocytoma (MFH) of the liver is uncommon, representing less than 1% of the primary malignant lesions of the liver. We report primary MFH of the liver in a 59-year-old woman. The tumor, measuring 9.0 9.0 6.0 cm, was located in the left lobe of the liver. It showed multiple areas of hemorrhage and necrosis. Microscopically, the tumor consisted of plump spindle cells haphazardly arranged in short fascicle and focal storiform pattern.
Multiple bizarre giant cells were also noted.
Immunohistochemically, many of the tumor cells were positive for vimentin and alpha1-antitrypsin but negative for epithelial markers. Ultrastructurally, the tumor cells showed fibroblastic and histiocytic features.

Abstract

- Benign hemangioma of the mediastinum is rare. This slowly growing tumor is described as well circumscribed, cystic, hemorrhagic tumor. Histologically it can be differentiated into capillary or cavernous form. We present a case of mediastinal hemangioma. A 20-year-old-man was presented with a slowly growing posterior mediastinal mass of 6 years duration, 8x6 cm in size. The mass was relatively well defined but focally invasive. Microscopically, it was differentiated into vessels of capillary, cavernous, and venous patterns. A solid cellular proliferation with inconspicuous capillary lumens was focally seen. The stroma between variable-sized vessels showed marked myxoid change associated with some smooth muscle bundles and adipose tissue. Ultrastructurally, areas of solid cellular proliferation showed formation of lumens. These lumens were lined by active endothelial cells showing plasmalemmal vesicles and Weibel-Palade bodies on the abluminal surface.
