Granulocytic sarcoma of the female genital tract: a clinicopathologic study of 11 cases.
Eleven patients, 13 to 76 (mean, 40) years of age, had granulocytic sarcoma of the female genital tract (FGT) (ovary, seven cases; vagina, three cases; cervix, one case). In nine cases, the FGT involvement was the initial clinical presentation of the disease, and in the other two cases, the FGT involvement was discovered during a relapse of acute myeloid leukemia. The tumors ranged from 0.5 to 14 (mean, 7.5) cm in greatest dimension. Two ovarian tumors were bilateral, and three were green. Microscopic examination revealed a predominantly diffuse pattern of growth, but cords and pseudoacinar spaces were also present focally in several cases. Sclerosis was seen in five tumors and was prominent in one. Prominent myeloid differentiation was readily recognizable on routinely stained sections in three cases, whereas the neoplastic cells in the other cases were primitive with only rare eosinophilic myelocytes. All 11 tumors were positive for chloroacetate esterase, nine of nine were strongly and diffusely positive for lysozyme, eight of eight for myeloperoxidase, seven of seven for CD68, and six of six for CD43. Examination of bone marrow or peripheral blood performed after the diagnosis of FGT involvement revealed acute myeloid leukemia in three of five cases. Two of these patients died of disease, 1 and 16 months after the initial diagnosis, and the third, who received chemotherapy, is alive and free of disease 8 months after the initial diagnosis. One of the two patients with negative bone marrow had recurrent granulocytic sarcoma 30 months after diagnosis and died of sepsis 1 month later; no residual disease was noted at autopsy. The other patient is alive and free of disease 18 months after the diagnosis. One of the four remaining patients with primary FGT involvement who did not have a bone marrow biopsy died of leukemia 24 months later; no follow-up information is available for the other three patients. One of the two patients with a prior diagnosis of acute myeloid leukemia was alive with disease 26 months later; follow-up is not available for the second patient. The diagnosis was often difficult in these cases, the most common problem being distinction from malignant lymphoma, but carcinoma, granulosa cell tumor, and, rarely, other tumors were considered. Immunohistochemical and enzyme histochemical staining were useful in establishing the diagnosis, although suspicion of the diagnosis on examination of routinely stained sections was of paramount importance.
