Idiopathic scrotal calcinosis

Idiopathic Scrotal Calcinosis is a rare, benign condition characterized by multiple, painless, hard cutaneous nodules on the scrotum. The condition is usually seen in middle-aged men and is not associated with systemic metabolic disorders or elevated serum calcium levels. The exact cause is unknown, hence the term 'idiopathic'.

Etiology

The etiology of Idiopathic Scrotal Calcinosis is not well understood. It is believed to be due to dystrophic calcification of the dartos muscle or degenerated epidermal cysts. Some researchers suggest that it may be a reaction to trauma or inflammation.

Clinical Presentation

Patients with Idiopathic Scrotal Calcinosis typically present with multiple, asymptomatic, firm nodules on the scrotum. The nodules vary in size and number. They are usually painless but may cause discomfort or embarrassment due to their appearance.

Diagnosis

The diagnosis of Idiopathic Scrotal Calcinosis is primarily clinical, based on the characteristic appearance of the lesions. Histopathological examination of the nodules reveals calcium deposits in the dermis with surrounding foreign body giant cell reaction.

Treatment

The mainstay of treatment for Idiopathic Scrotal Calcinosis is surgical excision of the nodules. This is usually done for cosmetic reasons or to relieve discomfort. Recurrence after surgery is rare.
