Abstract:
Objective To investigate the clinical and pathological features,diagnosis and differential diagnosis of isolated granulocytic sarcoma of the ovary. Methods The clinical manifestations,pathological features,immunohistochemistry,treatment and prognosis were analyzed in 1 case of isolated granulocytic sarcoma of the bilateral ovary with the review of literatures. Results Granulocytic sarcoma of the ovary was rare. Only 14 cases had been reported so far. This case presented a greenish masse arising from the right ovary measuring 10.0 cm × 8.5 cm × 6.0 cm and 4.8 cm × 3.0 cm × 2.2 cm mass in the left ovary. The neoplastic cells grew in a diffuse pattern or India file, composed of myeloid cells at various stages of maturation, being predominantly primitive myelocytes with a few immature eosinophils. Immunohistochemistry,tumor cells were strongly positive for MPO,CD117,CD43,but negative for CD79α,CD3 Conclusions In routine morpholog,granulocytic sarcoma may be misinterpreted as lymphoma,granular cell tumor,et al. Neoplastic cells at various stages of maturation,India file pattern and immature eosinophils are important diagnostic clues. Immunohistochemical stains are essential in order to obtain correct diagnosis. Despite the localized nature of tumor, intensive antileukemia chemotherapy is necessary.
