Chloroma, also called granulocytic sarcoma (GS) or Myeloid Sarcoma, is a rare malignant extra-medullary neoplasm of myeloid precursor cells. It is usually associated with myeloproliferative disorders but its appearance may precede the onset of leukaemia. The presence of a chloroma is certainly a sign of poor prognosis. We report a case of chloroma in a middle aged female without a prior history of leukemia in the perianal skin region with clinical diagnosis of perianal abscess. When there is no concomitant leukaemia, diagnosis of chloroma may be difficult. Differential diagnoses include acute lymphoblastic leukemia, large cell NHL, lymphoblastic lymphoma, Ewing's sarcoma and cutaneous T cell lymphoma.

Chloroma (granulocytic sarcoma or myeloid sarcoma) is a rare malignant extra-medullary neoplasm of myeloid precursor cells. It is usually associated with myeloproliferative disorders but very rarely may precede the onset of leukaemia. Here we are presenting a rare case of chloroma in a female patient without initial presentation of AML. 38 year old female patient, with performance score-1 had complaining of per vaginal bleeding for 1-2 days. Patient consulted gynaecologist and underwent biopsy from anterior fornix of vagina. Biopsy material was positive for LCA (leukocyte common antigen), MPO (myeloperoxidase), c-kit positive on IHC (immunohistocytochemistry) while negative for cytokeratin, synaptophysin, chromogranin, CD20 (cluster of differentiation. Whole body CT scan was non informative except mass lesion at vagina. Patient was given 3+7 induction chemotherapy which was tolerated well followed by high dose cytarabine as consolidation therapy.
