Scrotal calcinosis is a relatively uncommon, benign idiopathic disease presenting with multiple scrotal bumps that are rock-hard and smooth on touch and yellowish to white in color. These scrotal bumps are usually asymptomatic and the reason for doctor visit is its cosmetic concern. Although the disease itself is harmless and is not a major physical concern, most of the individuals find it embarrassing, because it can affect their sexual activities and lead to social problems.
Scrotal calcinosis, as name suggest is not due to calcium abnormalities, this occur in presence of normal calcium and phosphate metabolism. These scrotal bumps typically begins during childhood or early adulthood and present as single or multiple, painless, hard nodules with size varying from 1 mm to more than 1 cm in diameter. These lesions are usually asymptomatic, but sometimes it can be itchy, infected, ulcerated or may be associated with chalky white discharge from the bumps that can be very annoying.
Scrotal calcinosis is more common in dark colored individuals and commonly affects males but similar lesions (vulvar calcinosis) have been reported in female too. These lesions very rarely occur on penis. The exact cause and pathogenesis of scrotal calcinosis is unclear. Researchers are still unclear whether the disease is idiopathic or the result of dystrophic calcification of preexisting structures, including epidermal cyst, eccrine epithelial cyst, and degenerated dartoic muscle.
There are several other conditions that can be seen with similar presentations. In such cases your doctor may perform biopsy to confirm the disease. Disease that can have similar presentation are:
Treatment of Scrotal calcinosis
Although these scrotal bumps are harmless, but, because of its location and cosmetic concern individuals wants it removed, in such cases surgical intervention is required. Smaller lesions can be excised individually while for larger and massive lesions, wide excision and partial scrototomy with complex scrotal reconstruction may be necessary.
Even though scrotal calcinosis is harmless condition and excision can get rid of those bumps, it is important to know that it can recur and there is nothing you can do to avoid recurrence besides local friction and injury .
