Myeloid sarcoma is a tumor mass of immature myeloid or granulocytic cells that affects extramedullary anatomic sites, including uncommonly the oral cavity. A 24-year-old female was referred for evaluation of a fast growing painful gingival swelling lasting 2 weeks, associated with fever, fatigue, and cervical lymphadenopathy. Intraoral examination showed a bluish swelling on the right posterior...

Myeloid sarcoma initially occurring in the sacral canal is often misdiagnosed as other pathological tumors on MRI due to the lack of a definite history or clinical evidence of granulocytic leukemia. Here, we report a case of 24-year-old male patient with myeloid sarcoma misdiagnosed radiologically. On MRI, sacral myeloid sarcoma is characterized by homogeneous signal intensity, marked enhanceme...

Granulocytic sarcoma with no demonstrable abnormalities in the peripheral blood or bone marrow is a rare but recognised initial manifestation of acute myeloid leukaemia and has led to diagnostic difficulties in some cases. A lymph node excisional biopsy from a patient presenting with cervical lymphadenopathy, a mediastinal mass, and a normal peripheral blood picture was reported to have feature...

A 23-year-old woman presented with trigeminal neuralgia four months after hematopoietic stem cell transplantation (HSCT) for acute myeloblastic leukemia. No leukemic cells were found in the cerebrospinal fluid. Initial brain magnetic resonance imaging (MRI) did not reveal any abnormality. After symptom exacerbation with diplopia, second MRI showed an irregular mass at the right petrous apex, wi...

Light microscopical and routine immunohistochemical studies of a cervical neoplasm in a 32 year old woman initially suggested a histiocytic lymphoma, but histochemical staining for chloroacetate esterase established the correct diagnosis. This was supported by electron microscopic findings. Eight months later the patient developed a granulocytic sarcoma in her left breast and haemotological fea...

Granulocytic sarcomas are rare tumors composed of neoplastic blood cells, typically occurring during the course of acute nonlymphoblastic leukemia or before its onset. We present a case of a 23-year-old young adult man with metachronous granulocytic sarcoma of the testis without hematologic manifestations who was diagnosed with granulocytic sarcoma (GS). The patient was treated with right orchi...

Granulocytic Sarcoma (GS), an unusual extramedullary tumor, is composed of immature granulocytic precursor cells. The intraoral occurrence of this tumor is extremely rare. Here, we report a case of GS with palatal swelling, gingival lesions in maxilla and mandible and aleukemic presentation in a 45- year- old male.

Granulocytic sarcoma (GS) is a rare extra medullary solid tumour composed of immature myeloid cells. These tumours often display a greenish colour due to the enzymatic action of myeloperoxidase in the tumour cells. Hence, the term 'chloroma' was given to this lesion in 1853. GS commonly involves bone, periosteum, soft tissue, lymph node, and skin. Rare occurrences in muscle, meninges, breast, m...
