Multiple Osteoma Cutis of the Wrist and Hand

Abstract

Osteoma cutis is a rare, benign condition characterised by dermal or subcutaneous bone formation that presents as stony hard nodules. The disease is classified into primary and secondary forms. Primary Osteoma Cutis (POC) is not associated with any predisposing conditions, whereas Secondary Osteoma Cutis (SOC) occurs as a result of metabolic conditions that lead to an increase in blood calcium levels. Here, author present a case of a 21-year-old girl having multiple tiny stony hard nodules on the right wrist and hand. Syndromic association was ruled out by obtaining a thorough clinical history, accompanied by physical examination and search for laboratory signs of pseudohypoparathyroidism. This ultimately led to a more accurate diagnosis of isolated primary osteoma cutis, a very rare condition reported in the literature.
