Pterygium inversum unguis (PIU) or ventral pterygium is a rare abnormality characterized by the adherence of the distal nail bed to the ventral surface of the nail plate, resulting in obliteration of the distal groove.1 We report a case of idiopathic PIU presenting with a pathological lesion and severe pain.
A 47‐year‐old man presented with a 4‐month history of pain in both index fingernails. Both index digits showed aberrant extension of the hyponychium attached to the ventral surface of the distal part of the nail plate (Fig 1a). This was causing severe tenderness, especially in the left index fingernail, which had a mean pain score of 8 on a 10‐point visual analogue scale. The patient reported that he had experienced no previous trauma or nail disease, and no family history of similar abnormality. Physical and systemic examinations found no evidence of connective tissue disease, and the patient had no personal or family history of such disease. Because the pain was so severe, and was relieved only temporarily by nonsteroidal anti‐inflammatory drugs and analgesics, we chose to treat the condition surgically.
