The diagnosis of malignant histiocytosis is usually based upon typical light microscopic features of the neoplasm. Supplementary cytochemical and immunologic features have been suggested as typical of malignant histiocytosis. The present study was prompted by an unusual erythropagocytic hepatocellular carcinoma having immunologic and cytochemical markers suggesting mononuclear phagocytic origin. Twenty-four neoplasms of unquestionable epithelial origin were prospectively evaluated for activity of alpha-naphthyl acetate esterase, a cytochemical marker useful in distinguishing between the non-Hodgkin's lymphomas and malignant histiocytosis. The epithelial tumors represented a broad spectrum of tissue origins and consistently demonstrated alpha-naphthyl acetate esterase activity. Thus, erythrophagocytosis and alpha-naphthyl acetate esterase positivity may be misleading in the unusual instance in which the histopathologic differential diagnosis includes malignant histiocytosis and epithelial neoplasia. Ultrastructural assessment is useful in the exclusion of poorly differentiated carcinoma.
