Lee, Ga Young; Choi, Hae Young; Myung, Ki Bum

Abstract

Osteoma cutis was first described by Wilkins in 1858 and it is a primary cutaneous ossification, which has no preceding trauma or skin disease and no evidence of Albright's hereditary osteodysttophy in the patient or his family. The lesions appear as hard, round to irregular, sharply defined tumors of varying size within the dermis or subcutis, and their color range from red to purple or brown. We report a rare case of multiple osteoma cutis in an infant. A 10-month-old female infant presented with multiple hard purplish nodules on the abdomen for several months and did not show any evidence of Albright's hereditary osteodystrophy and signs of secondary cutaneous ossification such as trauma, injection, and previous skin lesions. The histopathologic finding shows intradermal bony spicules with numerous osteocytes, cement lines, osteoblasts, and osteoclasts.
