A rare case of recurrent eccrine poroma underlying gluteal abscess.

INTRODUCTION: Eccrine 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 CASE: We 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.

DISCUSSION: Given 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.

CONCLUSION: Gluteal 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.
