Ackerman tumorAckerman tumor is a distinct variant of well differentiated squamous cell carcinoma that occurs in the oral cavity, larynx, nasal cavity, esophagus, penis, vulva, perinatal skin, and the soles of the feet. It is associated with the use of tobacco and presents as a large fungating papillary growth that frequently becomes infected. Microscopically, the tumor is well differentiated with benign appearing papillomatosis, acanthosis and hyperkeratosis. By definition, Ackerman tumor lacks significant cytologic atypical of more poorly differentiated squamous cell carcinomas.
Adequate excision is curative in most cases. Metastases are rare.
