Idiopathic scrotal calcinosis

Presentation

• Single or multiple hard, marble-like nodules of varying size affecting scrotal skin.
• Nodules vary in size from a few millimeters to a few centimeters.
• Usually start to appear in childhood or early adult life
• Over time, nodules increase in number and size
• Nodules may break down and discharge chalky material
• Rarely, lesions may be polypoid
• Usually asymptomatic

  Etiology

Diagnostic

• Clinically Relevant Pathologic Features
• Lesions slowly progress throughout life
• * They slowly increase in number and size
• Nodules are mobile and do not attach to underlying structures

• Globular and granular purple deposits within dermis surrounded by giant cell granulomatous reaction
• Sometimes remnants of cystic lesion can be identified
• Very distinctive appearance with almost no histologic differential diagnosis.

  Treatment

Prognosis

• Benign condition
• Slow progression throughout life
• Lesions remain discrete and do not become confluent

  Epidemiology

• Incidence: uncommon
• Age: children and young adults
