A case of sclerotic fibroma

Abstract

Sclerotic fibroma is one of the histologic variants of soft fibroma. Clinically, it presents as a solitary skin-colored nodule, usually less than 1 cm in diameter in adults and has a wide anatomical distribution. Histologically, it is a well-circumscribed dermal nodule composed of hypocellular hyalinized collagen bundles separated by clefts and arranged in a storiform pattern. Treatment with simple excision is curative. We report a case of sclerotic fibroma in a 34-year-old man who presented an asymptomatic, bean-sized, intracutaneous nodule on his back for 3 years.
