Introduction: skin´s adnexal tumors represent a heterogeneous group of lesions of low frequency of presentation, which can cause certain diagnostic difficulties for the general pathologist. Materials and methods: a retrospective study was carried out. The reports about adnexal tumors performed in the institution between the years 2000 and 2007 were revised. The Who classification of adnexal tumors from the consensus of 2003 in Lyon was used. The gender, age, localization, histopathology, margins and other characteristics of the biopsies were revised. Results: 200 reports were revised corresponding to 178 patients. 13 of them presented more than one tumor. 50% were men. Among all the reports, 47% corresponded to follicular tumors, 42% to apocrine and eccrine tumors and 11% to sebaceous tumors. Between the follicular ones, the pilomatricomas were the most common (67%), among apocrine and eccrine ones, were the syringomas (24%) and the sebaceous carcinomas (63%) were the principal diagnostic as regard sebaceous tumors. 84.5% were benign, 12% were malignant and 3.5% were of uncertain biological potential. There was a female predominance between the apocrine and eccrine tumors. The sebaceous and follicular tumors were more common in men. The follicular ones were diagnosed in earliest ages, in contraposition with the sebaceous ones, diagnosed in advanced ages. All of these tumors were more frequent in cephalic region. Conclusions: our results showed concordance with the literature and confirmed the heterogeneity of these tumors in their presentation as skin biopsies, in despite of their low frequency.
