A 30-year-old Bangladeshi migrant worker with no underlying medical history, complained of multiple growths on his scrotum for the preceding three years [Figure 1]. It started with a single ‘pea-like’ swelling over the right scrotum which later grew in size and increased in numbers until both sides of the scrotum became affected. Aside from occasional itchiness, the growths were not associated with any ulceration, pain, or abnormal discharge. There was no history of preceding trauma, urogenital, or constitutional symptoms. Physical examination revealed multiple firm and nontender skin-colored nodules on both sides of the scrotum with the largest measuring 2 cm in diameter. There was no lymphadenopathy, and no similar lesion was found elsewhere on the body. Laboratory investigations reported normal levels of serum calcium, phosphorus, and parathormone. Excisional biopsy of the nodule showed multiple amorphous calcium deposits within the dermis free of epithelial lining or surrounding granulomatous reaction. Question 1. What is the diagnosis? a. Scrotal calcinosis. b. Nodular scabies. c. Epidermal cyst. d. Steatocystoma.
