Heterotopic Ossification Combined with Infection in the Hand: A Case Report

ABSTRACT

Heterotopic ossification was defined as the formation of mature lamellar bone in soft tissues. Heterotopic ossification of the hand has been rarely reported. Plain radiograghs of a 71-years-old female patient who had denied a definite trauma history showed a diffuse mass with calcified density between the ulnar styloid process and the 5th metacarpal bone of his right hand. Histopathologic assessment revealed heterotopic ossification with acute cellulitis. There was no evidence of recurrence for 3-year follow-up after wide excision.
