Abstract
- Cutaneous granulocytic sarcoma are rare extramedullary tumor composed of immature leukemic cells of the myeloid series. It has a characteristic greenish color caused by myeloperoxidase in the granulocytic cells. 58-year-old female patient who had been diagnosed as acute myelocytic leukemia presented multiple, variable sized, tender brown-pigmented nodules, papules and plaques on the abdomen and both upper extremities for about 4 weeks. An incision biopsy of the large subcutaneous nodule on her abdomen showed a dense dermal infiltrate of immature myeloblastic cells with pleomorphic hyperchromatic vesicular nuclei and conspicuous nucleoli. A punch biopsy of the other small papule on her abdomen showed an infiltrate of granulocytic cells with round hyperchromic nuclei and granular acidophilic cytoplasm, between the dermal collagen bundles. We present a case of the cutaneous granulocytic sarcoma (chloroma) with coexistent leukemia cutis in acute myelocytic leukemia developed from myelodysplastic syndrome.
