Résumé
Abstract: Eccrine poromas and porocarcinomas are adnexal tumors derived from the sweat duct epithelium. However, eccrine poroma is benign in nature, whilst eccrine porocarcinoma is regarded as its malignant counterpart. We report the case of a man who presented simultaneously with an eccrine poroma and eccrine porocarcinoma. Both lesions had no clear distinctive features, enhancing the need of high-level clinical suspicion together with surgical excision and histopathology for prompt diagnosis confirmation.

Los tumores anexiales de la piel representan un grupo heterogéneo de entidades de baja frecuencia de presentación. Su origen es controvertido, quizás a partir de células madres pluripotenciales, aceptándose principalmente dos líneas embriológicas: pilosebáceo-apócrina y ecrina. Se los clasifica en cuatro grupos principales: tumores del folículo piloso, tumores sebáceos, tumores apócrinos y tumores ecrinos. Su distribución anatómica refleja áreas con mayor densidad de anexos cutáneos, presentándose en forma única o múltiple.
Skin adnexal tumors are represented as a heterogeneous group of entities of low frequency range. Its origin is controversial, perhaps from pluripotent stem cells, mainly from two embryological lines: pilosebaceous-apocrine and eccrine. They are classified as four main groups: tumors of the hair follicle, sebaceous tumors, apocrine tumors and eccrine tumors. Their anatomic distribution reflects areas with the highest density of cutaneous adnexal, arising in either single or multiple forms.
