Granulocytic sarcoma of the uterine adnexa is a rare event. A 50-year-old woman, who had previously been diagnosed as chronic myeloid leukemia (CML), but had a complete hematologic response, presented with lower abdominal pain and a large pelvic mass involving the right uterine adnexa region and extending to the right posterior wall of the bladder and right distal ureter. A biopsy of the uterin...

We report an 18-months old boy with trisomy 21 who initially presented with myelodysplastic syndrome MDS, and later transformed into acute megakaryoblastic leukaemia AML. At presentation he was found to have some unusual findings namely multiple soft tissue masses over scalp, left elbow and over the knee joints as well as hard mass felt in left hip. Biopsy of soft tissue of scalp revealed granu...

Localized tumors composed of immature cells of the myelogenous series have been recognized for many years as an uncommon manifestation of granulocytic leukemia. The histologic diagnosis of chloroma (granulocytic sarcoma) may be extremely difficult when the myeloblastic cells are poorly differentiated and the tumor lacks the characteristic green color. The diagnostic difficulty may be further co...

Granulocytic or myeloid sarcoma (MS) is a rare neoplastic condition consisting of a tumor mass of myeloid blasts with or without maturation occurring at an anatomical site other than the bone marrow the association between tuberculosis and MS is extremely rare. A 21-year-old female patient presented cough, sore throat and a suppurative swollen gum for 10 days prior to hospital admission. Physic...

A 29-year-old woman presented with a breast tumor with a primary diagnosis of MALT lymphoma. A repeat biopsy revealed a hematological neoplasm with diffuse, Indian file, and targetoid patterns. The cells were intermediate size with eosinophilic granules; the immunophenotyping showed monocytic differentiation, and no lymphoepithelial lesion was observed. The diagnosis was granulocytic sarcoma. T...

A 52 year old man with newly diagnosed polycythaemia vera in proliferative phase developed widespread extramedullary haemopoiesis (EMH), and died as a result of cervical cord compression. At necropsy, microscopic areas of primitive cells characteristic of granulocytic sarcoma were found within a large tumour of EMH in the right retroperitoneal region. Ultrastructural analysis showed unusual hex...

Granulocytic sarcoma or chloroma is a tumor seen in myelocytic leukemia. Spinal epidural onset is rare and is generally seen before or together with the onset of myelocytic leukemia. An epidural mass located at the 2nd-5th thoracic levels in an 18-year-old male patient was pathologically diagnosed as granulocytic sarcoma. Radiotherapy was performed after surgical intervention. Ten months later,...
