Fine-needle aspiration cytology of ameloblastic carcinoma of the maxilla: a rare tumor.
This report describes the cytologic, histologic, and clinical features of an ameloblastic carcinoma of the maxilla occurring in an 83-yr-old white male. A fine-needle aspiration revealed malignant cells with a predominantly small cell type morphology. There were also a few cells of a second type which were more polygonal to spindled with oval to elongate nuclei. A focal amorphous blue-grey matrix was noted in association with these cells. Although the biopsy showed prominent areas of squamous metaplasia, no squamous cells were seen in the cytologic sample.
