We report a case of a 38-year-old man who complained of abdominal pain. Physical examination revealed a firm mobile mass, 25 cm in diameter, in the left lower abdominal wall. The tumor was first thought to be a sarcoma arising from the omentum or mesentery. During surgery, a large tumor was found attached to the inner surface of the abdominal wall and compressing the gastrointestinal tract. On microscopic examination the tumor corresponded to a biphasic synovial sarcoma immunoreactive for cytokeratins (AE1/AE3, 7 and 19), epithelial membrane antigen and carcinoembryonic antigen in the epithelial tumor cells, for E-cadherin especially in their glandular structure, vimentin, CD99, and CD56 in the spindle cell component and for bcl-2 protein. The tumor recurred at the same site, and clinical course progressed to death 3 months after the initial diagnosis.

We reviewed 8057 bone marrow studies made over a period of 10.5 years, confirming the presence of granulomas in 40 patients. Global incidence was 0.50% and annual incidence 3.80 cases/yr. Because of the non-specificity of the morphological data, the diagnostic significance of the finding is limited, but it does serve to narrow the field of etiological possibilities. Associated disease was demonstrated in 82.5%, infectious diseases being the most common (tuberculosis, brucellosis, typhoid fever and kalaazar). Two previously unpublished entities are introduced: refractory anemia with excess blast cells (dysmyelopoietic syndrome) and malignant histiocytosis. 3 patients presented human immunodeficiency virus infection, the etiopathogenic role of this retrovirus in the generation of granulomas being unknown. The efficacy of bone marrow study in demonstrating granulomas increases if both the aspirate clot and bone cylinder are examined.
