【 摘 要 】

Malignancy occurs ever so rarely on pilonidal cyst late evolution, so much so that less than 70 cases have been described until 2007. As in other etiologies, malignancy in chronic wounds is named Marjolin's ulcer. Generally, the incidence of low grade and differentiated tumors is most frequently noticeable. Squamous cell carcinoma is the most frequent one. However, these are aggressive tumors, with high rates of recurrence and lymph node metastasis. We report the case of a male patient, 41 years-old, about 23 years of sacroccygeal pilonidal disease evolution, whose has developed malignancy (squamous cell carcinoma), submitted to surgical and radiotherapic treatment.
