Primary oral myeloid sarcoma: Report of a case

Abstract

Myeloid sarcoma is defined as a tumor mass of immature myeloid cells that may be observed in a variety of locations including bone, skin, lymph nodes and soft tissues. However, oral involvement of myeloid sarcoma is extremely rare. These tumors are considered as specific lesions of acute myeloid leukemia. We present a case of a myeloid sarcoma of the upper vestibular gingiva in a 29-year-old woman who has no hematologic disease history. Multiple metastases were found in floor of the nasal cavity, left breast, and left lacrimal gland 12 months after primary diagnosis.
