Unusual plaques on the back

Solitary Plaque-type Morphea with Dystrophic Calcinosis Cutis

“…A large series of patients failed to detect this phenomenon: Christianson et al (8) studied 83 patients with localized plaques of morphea and Muller et al (9) 74 cases, and no instances of calcinosis cutis were found. As far as we know, only one case of calcinosis in plaque-type morphea has been reported in the English literature during the past 30 years: it was located on the upper back in a 69-year-old woman, and calcinosis was successfully treated with surgical removal (10). There is no specific treatment for this condition, and various treatments have been reported with variable results: systemic or intralesional corticosteroids, colchicine, minocycline, bisphosphonates, warfarin, ceftriaxone, and surgical excision, among others (5,7,11).…”
