A rare presentation of proliferative trichilemmal cyst in an ear lobule
Journal Title: Scholars Journal of Medical Case Reports - Year 2015, Vol 3, Issue 9
Abstract
Abstract: Trichilemmal cysts, also called pilar cysts, are known skin lesions arising from the outer root sheath of the hair follicle. Proliferating trichilemmal cysts or pilar tumours, thought to arise from these lesions, are much less common. They are generally present on the Scalp. Other locations, although much less common, have been reported. To our best knowledge proliferating trichilemmal cysts involving a non hairy area like an ear lobule have not been reported so far. Hence we report this rare case of a cyst involving the ear lobule for which excision biopsy was performed and histopathological findings were consistent with those of proliferative trichilemmal cyst. Hence it should be considered as a differential diagnosis in case of swelling in a non hairy region. Keywords: Ear lobule, non hairy region, nodular swelling, Proliferative trichilemmal Cyst
