Malignant degeneration of pilonidal sinus is a rare complication observed mainly in recurrent chronic cases of the disease, associated to a very bad prognosis. In the world's literature we find it like an infrequent entity. In Spain had reviewed 367 patients with simple and complicated pilonidal cysts. We found three cases (0.81%) of epidermoid carcinoma.
Men's 60 years of age, with clinical picture of 50 years of evolution with the presence of sacral tumor, is resection and histopathological reporting of pilonidal cyst; taking evolution at healing, with necrotic edges; resection of these will decide and report is squamous cell carcinoma.
Pilonidal sinus epidermoid carcinoma is an infrequent disease predicting for very poor outcome.
藏毛窦恶性变是一种罕见的并发症，主要见于该疾病的复发性慢性病例，预后很差。在世界文献中，我们发现它是一种罕见的病症。在西班牙，对367例单纯性和复杂性藏毛囊肿患者进行了回顾性研究。我们发现3例（0.81%）表皮样癌。
一名60岁男性，有50年病程的骶尾部肿物临床表现，对藏毛囊肿进行了切除及组织病理学报告；愈合过程中出现边缘坏死；切除后诊断并报告为鳞状细胞癌。
藏毛窦表皮样癌是一种罕见疾病，预后极差。
