Idiopathic Circumscripta Calcinosils Cutis of the Fingers

Abstract

Calcinosis cutis is an uncommon disorder characterized by deposition of insoluble calcium salts in the skin. Based on the etiology of the deposition, calcinosis cutis may be divided into four major groups, namely, metastatic, dystrophic, idiopathic, and iatrogenic The pathophysiology of calcinosis cutis remains unclear. The dystrophic form is the most common whereas the idiopathic one is the rarest. Idiopathic calcinosis cutis occurs in the absence of any identifiable causes and it has no association with drug use. Idiopathic calcinosis cutis has two major types called localized (circumscript) and generalized (universalis). Localized type generally involves the vulva, scrotum, penis and the breast. A definitive diagnosis requires the histologic demonstration of the accumulation of calcium in the skin and exclusion of other clinic types. There is not an effective treatment for the disease. A 47-year-old woman presented to our outpatient clinic with painless, yellowish-white nodules on her hand enduring for 30 years A diagnosis of idiopathic calcinosis cutis was made by clinical and histological findings. We present this case because, to our knowledge, the localization of the lesions in our case has not been previously reported in the literature.
