The cytopathologic features of the fine needle aspiration cytology of the local recurrence of a vulvar epithelioid sarcoma were documented. The cytologic findings included round polygonal cells with abundant eosinophilic cytoplasm and an eccentrically located nucleus. Despite their epithelioid aspect, the cells in the smears had a sarcomatous arrangement, consisting of isolated cells and loosely cohesive groups. The cytologic findings correlated well with the histologic features of the tumor, which consisted of nodules of eosinophilic epithelioid cells. We discuss the clinical characteristics and prognostic factors in this unusual, vulvar location of this soft tissue sarcoma.

A case of neurilemoma of the left breast in an 83-year-old man is presented, including the fine needle aspiration and biopsy diagnosis. A review of the literature did not reveal the existence of such a tumor in a man's breast. The aspirate yielded a cellular smear composed of clusters of spindle-shaped cells showing minimal atypia and Verocay bodies. The final diagnosis was established on the excised mass through histopathologic study.

The penetration of a gastric peptic ulcer into the liver was initially diagnosed by the cytologic examination of endoscopic brushings and later confirmed by an endoscopic biopsy of the stomach. One of the smears of the gastric brushing contained sparse groups of liver cells with mild atypia. The endoscopic biopsy specimen included liver parenchyma with signs of peptic hepatitis. The differential diagnostic considerations for a gastric brushing containing hepatoid cells are discussed.

Clinicoradiologic and pathologic data of a patient with a paraganglioma of the cauda equina are described. The peculiar aspect of this rare case is the gangliocyte differentiation with mature ganglion cells scattered in the tumor. The histologic and ultrastructural features are similar to other described cases of this tumor, with Zellballen pattern and neurosecretory granules. The immunohistochemical studies are quite typical with positive staining with neuroendocrine markers (N.S.E., G.F.A.P.). An interpretation of these findings is made.

The malignant schwannoma is a sarcoma which very rarely occurs on the face. This article describes the case of a woman with such a tumour and whose study and evolution shows that was no relation with the nervous trunk, neurofibroma or neurofibromatosis.
