Myeloid sarcoma, considered to herald the onset of a blast crisis in the setting of chronic myeloproliferative neoplasm/dysplasia, typically presents during the course of the disorder. Cutaneous involvement is uncommon and lesions on genital skin are seldom seen. We present a case of a well-differentiated myeloid sarcoma in the penile foreskin in an apparently healthy 29-year-old male presentin...

The purpose of this report is to present a case of myeloid sarcoma of the gingiva with myelodysplastic syndrome.A 52-year-old male diagnosed with myelodysplastic syndrome with skin lesions presented with gingival swelling and gingival redness involving the maxillary left second premolar and the maxillary left first molar. The patient was referred from the Department of Hematology for a biopsy o...

Granulocytic sarcoma is an extramedullary tumor which is composed of myeloblasts and immature myeloid cells. It usually occurs in association with acute myeloid leukemia and most commonly involves skin, soft tissue, lymph nodes, bone, and periosteum. We report a case of isolated ureteral granulocytic sarcoma without hematologic manifestations. Our patient presented with bloody urine and left-si...

As defined by the World Health Organization classification of tumors of hematopoietic and lymphoid tissue, myeloid sarcoma (MS) is a tumor mass of myeloblasts or immature myeloid cells that can arise before, concurrent with, or following acute myeloid leukaemia. We describe a case of secondary leukemia presenting itself as MS of the breast in a patient previously treated for a non-Hodgkin's Lym...

Myeloid sarcoma is a rare solid tumor consisting of myeloid blasts that proliferate in any extramedullary site. It can present before, concurrent with or after the diagnosis of acute myeloid leukemia [AML] or other myeloproliferative disorders. The most common sites include skin, gum, lymph nodes, soft tissue, periosteum, and bone. Here, we present a 66-year-old male with a history of bladder c...

Myeloid sarcoma (MS) is an extramedullary solid neoplasm of immature myeloid cells. These tumours usually develop in concurrence with or following acute leukemia. The breast is an uncommon site for presentation of this tumour, where it is often misdiagnosed as lymphoma or carcinoma.A 33- year-old female presented with a right breast lump in a private hospital, which was diagnosed as ductal carc...

Myeloid sarcoma (MS), also termed extramedullary acute myeloid leukemia, extramedullary myeloid tumor, and granulocytic sarcoma or chloroma, is a rare manifestation that is characterized by the occurrence of 1 or more tumor myeloid masses occurring at an extramedullary site. The wide spectrum of this disorder and the conditions that it overlaps diagnostically were well reflected in the 25 cases...

Myeloid sarcoma is known as a tumor mass of myeloblasts or immature myeloid cells occurring in an extramedullary site. When ophthalmic areas are involved, it is usually located in the orbits and noted at or after the diagnosis of an underlying leukemia. We report a 38 year-old woman who had isolated conjunctival myeloid sarcoma without any other clinical signs and symptoms. Acute myeloid leukem...

Myeloid sarcoma (chloroma, granulocytic sarcoma, or extramedullary myeloid tumour) is an extramedullary mass forming neoplasm composed of myeloid precursor cells. It is usually associated with myeloproliferative disorders but very rarely may precede the onset of leukemia. Here, we are presenting a rare case of primary vaginal myeloid sarcoma in a geriatric female patient without initial present...
