Primary gynecologic myeloid sarcomas are rare, and their diagnosis is often difficult. Differential diagnosis includes lymphomas and carcinomas of the gynecologic tract. We report the clinical, morphological, immunohistochemical and cytogenetic features of two cases of chloromas of the female genital tract, which progressed to acute myeloid leukemia in spite of aggressive therapy.

We report the clinical, cytological, immunophenotypic, and cytogenetic findings in one patient with acute erythroblastic leukemia. Blast cells were identified by their reactivity with the early erythroid antibodies FA6–152 and carbonic anhydrase I. The leukemic blasts had no specific differentiating features identifying them as erythroblasts even at an ultrastructural level. Cytogenetic studies revealed multiple chromosome aberrations: 45, XX, i(11q), -16, -17, -21, + der(21) t(21;?)(q22;?), + mar 1.
