title: Bone involvement and abcess formation by neutrophil-rich CD30+ anaplastic large-cell lymphoma mimicking skeletal infection in an AIDS patient.
abstract: Neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) is a rare pathological entity without distinct clinical behavior. Twelve cases of neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) have been reported, three of them were HIV-infected patients. All these reports stressed the presence of neutrophil infiltration as a new morphologic feature of CD30+ ALCL. Only one case of cutaneous involvement presented with microabscess formation. We describe a case of neutrophil-rich CD30+ ALCL in an AIDS patient with a clinical picture determined by the massive neutrophil infiltration of the tumor without necrosis nor local infection, but with the formation of abscesses.
