Frontal osteomyelitis presenting as upper eyelid ectropion: A cautionary tale.

Frontal osteomyelitis is a rare clinical entity that can occur as sequelae to frontal sinusitis, head trauma, as a postoperative complication following sinus surgery or due to haematogenous spread. It usually presents with a soft, fluctuant forehead swelling with pain and fever. Cicatricial ectropion is an extremely rare feature of frontal osteomyelitis. We present a young male patient presenting with cicatricial ectropion that occurred as the sole manifestation of an underlying frontal osteomyelitis. Extensive Medline search did not find any such reported case. We feel that frontal osteomyelitis should be kept in mind as a possible etiology when considering the differential diagnosis of cicatricial ectropion.
