Surgically Treated Giant Idiopathic Calcinosis of the Scrotum

Idiopathic calcinosis of the scrotum, first identified in the 1970s, is a rare condition typically affecting young men. This report presented a case of a 38-year-old man with no significant medical history who had been aware of a scrotal mass for 10 years, noting a gradual increase in its size. Upon presentation to our hospital, the lesions on both sides of the scrotum were larger than an adult's palm, greatly affecting his daily life. A biopsy revealed numerous calcifications without clear underlying pathology, leading to a diagnosis of idiopathic calcinosis of the scrotum. Complete lesion excision and defect reconstruction with a skin graft showed favorable outcomes. This case was notable because the scrotal mass size (2 pieces measuring 20 × 11 cm) was greater than those detailed previously. Skin grafting was indicated after extensive lesion excision, which has been found effective for scrotal reconstruction.
