Severe perifolliculitis capitis with osteomyelitis.

This report describes a severe case of perifolliculitis capitis with the rare complication of skull osteomyelitis, a combination not previously reported. The patient demonstrated the typical features of perifolliculitis capitis, namely, rubbery, hard, elevated nodules involving almost the entire scalp with multiple deep-seated abscesses. Bone was exposed in two areas and the diagnosis of skull osteomyelitis was confirmed by skull x-ray films and bone biopsy specimens, which grew Staphylococcus aureus. The patient was treated with enteral hyperalimentation, intravenous antibiotics, and multiple debridements of the scalp, including the involved periosteum and outer cortex of the exposed bone, followed by reconstruction with split-thickness skin grafts. A complete eradication of the disease with closure of all open wounds and clearance of osteomyelitis of the skull was achieved.
