Idiopathic scrotal calcinosis, sometimes called dystrophic scrotal calcinosis, is a rare benign condition characterised by superficial calcifications within the skin of the scrotum of unclear aetiology.
On this page:
Epidemiology
Idiopathic scrotal calcinosis typically affects men aged 20-40 years.
Pathology
Proposed aetiologies for idiopathic scrotal calcinosis includes epidermal inclusion cysts which calcify, necrosis and degeneration of the dartos muscle leading to dystrophic calcifications, and excessive discharge in eccrine epithelial cysts which leads to calcification of the debris build up in the lumina.
Radiographic features
Plain radiograph
They appear incidentally on pelvic exams as multiple rounded opaque bodies over the scrotum shadow 3.
Ultrasound
They appear as multiple nodules seen at scrotal wall with hyperechoic content with posterior acoustic shadowing with the presence of calcific foci. No vascularity on colour Doppler 3.
CT
Scrotal wall rounded calcific bodies are seen.
Treatment and prognosis
The condition is usually asymptomatic and surgery is required for cosmetic purposes 3. The condition may recur following excision of the calcified bodies.
