Proliferative fasciitis: A rare cause of disturbances in an adolescent hand

We report a case of hand soft tissue tumor-proliferative fasciitis (PF)-in a 12-year-old patient that presented as a painful lump causing trigger finger. After meticulous diagnostic workup, a surgical excision led to immediate amelioration of symptoms. PF is a rare benign pseudosarcomatous lesion arising typically in the subcutaneous tissue and fascia in adults. It is very uncommon in the hand. To the best of our knowledge, this is the first report of a trigger finger being caused due to this pathology. In this report, the authors review PF lesions on hands, advice careful evaluation of magnetic resonance imaging features, and recommend surgical management.
