Malignant eccrine spiradenoma of the nasolabial fold: a case report
Malignant eccrine spiradenoma (MES) is a rare malignancy of the eccrine sweat glands. It usually presents as a small, firm, reddish painful and small solitary nodule. Head and neck are rare locations. Etiology is unknown although previous trauma is believed to be an implicated factor. MES arises over a prior benign spiradenoma. Clinical behavior is aggressive with a high rate of recurrences and distant metastases. Prognosis is poor. Diagnosis is based on histological findings and treatment must be aggressive from the beginning to achieve the best results. Since Kersting and Helwig first described the case in 1956, and Beekley et al., reported its malignant transformation in 1971, only a few cases can be found in the literature. Based on these particular features we report a case of a 75-year-old man diagnosed on a MES that arises in a very unusual location, with a peculiar histopathology and behavior.
