A rare case of recurrent eccrine poroma underlying gluteal abscess

Abstract

IntroductionEccrine poroma is a benign adnexal neoplasm originating from epidermal sweat ducts mainly affecting the palmoplantar skin, buttock as a location of origin of poroma has rarely been reported, it is the first reported case of recurrent poroma in this site. Presentation of caseWe report an unusual case of eccrine poroma in the gluteal region of a 62 years old female associated with gluteal abscess, surgically excised with histologically clear margins, then recurred after one and half year with a given history of mild trauma. DiscussionGiven the uncommonness of these neoplasms, there stays a general lack of data on pathogenesis, atypical presentation, atypical sites, recurrence and risk of malignant transformation into porocarcinoma. ConclusionGluteal skin is an unusual location for a benign poroma. Early recognition and appropriate treatment at the initial presentation by complete resection with histopathology confirmation and follow-up are crucial to ruling out other diagnoses, such as lesions of malignant transformation.
