HEMATOGENOUS OSTEOMYELITIS WITH INFLAMMATORY CYST FORMATION MIMICKINGA SOFT-TISSUE TUMOR

Reported is a case of hematogenous osteomyelitis of the femur with inf lammatory cyst formation mimicking a soft-tissue tumor. A 15-year-old boy with a three-year history of a gradually enlarging soft-tissue mas s of his left thigh was found to have an aborted acute hematogenous os teomyelitis complicated by an inflammatory cyst that was probably caus ed by inadequate antibiotic therapy. The osteomyelitis and its inflamm atory cyst were treated with excisional debridement and six weeks of a ntibiotic therapy. The patient remains well five years later, with no clinical or radiologic evidence of recurrence. This is a new variant o f chronic osteomyelitis that has not previously been reported.
