title: CD30-positive T-cell lymphoproliferative disorder of the oral mucosa--an indolent lesion: report of 4 cases.
abstract: Four cases of CD30-positive T-cell lymphoproliferative disorder (CD30+ LPD) of the oral mucosa are described. This article aims to draw attention to this entity and to emphasize its usual benign clinical behavior despite its resemblance to T-cell lymphoma. All the patients were adults. Three of the lesions were on the dorsal surface of the tongue and 1 affected the buccal mucosa. All biopsies showed a dense lymphoid infiltrate composed of CD30+ atypical T cells with a polymorphous infiltrate in the background, which included eosinophils. In 1 case, monoclonal T-cell expansion was detected by molecular techniques. Three cases tested for Epstein-Barr virus were all negative. It is concluded that primary CD30+ T-cell LPD of the oral mucosa can be regarded as the oral counterpart of cutaneous CD30+ LPD such as lymphomatoid papulosis or anaplastic large cell lymphoma. Recognition of the condition is important to avoid overtreatment.
