RESUMO
INTRODUCTION: A pilomatrixoma is a benign appendage tumour related to hair cells matrix. Most of the literature review about pilomatrixoma is in the form of case reports with fewer cohort studies. The objective of this cohort is to study the variable demographic characteristics, presentation and histopathology of this condition among a larger group of patients. MATERIALS AND METHODS: We conducted a retrospective study of patients who had excision of pilomatrixoma between February 1998 and August 2011 in a District General Hospital in UK. RESULTS: The study included 67 patients with histopathologically diagnosed pilomatrixoma. The mean age was 32 years. Male to Female ratio was 35:32. The average diameter of the lesion at presentation was 13 mm (range: 2-30 mm). 66 of 67 (98.5%) patients presented with solitary lesion, while 1 patient (1.5%) had two lesions. CONCLUSION: Pilomatrixoma is not an uncommon benign lesion. It is more common in the maxillofacial area.
