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.

Unicystic ameloblastoma is not a rare odontogenic tumor in the pediatric population. A significant care should be given to unicystic ameloblastoma if it has mural invasions due to its local aggressiveness, high recurrence rates and radical management options as in conventional ameloblastoma. Fine needle aspiration (FNA) cytology is a rapid, non-traumatic diagnostic method that provides a required attention prior to surgery. We present an excisionsl biopsy proved FNA diagnosed mural type unicystic ameloblastoma in a 9-year-old child recurred as a solid ameloblastoma after 8 years. When distinctive features of ameloblastoma are known, an accurate diagnosis can be made by FNA cytology, in combination with clinicoradiological findings. This method gives benefit to the patients especially the younger ones both for the pre-operative surgical planning and the post-operative follow-up.
