BENIGN PROLIFERATING PILAR TUMOUR OF THE ELBOW – A RARE CASE REPORT

Abstract

Benign proliferating pilar tumour also known as proliferating trichilemmal cyst is a rare tumor usually occurring on the head and neck region of elderly women and its pathognomonic feature is trichilemmal keratinization. Here, a 65 year old elderly female presented to us with a benign proliferating pilar tumour of the right elbow for the past 6 months for which wide local excision and a local flap was used to cover the post excisional defect. This should be differentiated from trichilemmal cyst as it has potential for malignant transformation. Thus, complete excision is recommended for all benign proliferating variants owing to their potential for locally aggressive behavior and malignant transformation.
