title: Mandibular lymphomas with sclerosis.
abstract: Two cases of non-Hodgkin's lymphoma that show a sarcomatoid pattern within the jaw are described. Their primary origin in bone was demonstrated by radiologic studies. In one case, diagnosis was delayed because the clinical picture suggested inflammatory periodontal disease. In both cases, the histologic picture was similar to that of a sarcomatoid neoplasm with intense stromal sclerosis; hemimandibulectomy was performed in one case. The tumor contained cells with large, irregular, sometimes lobulated nuclei and high mitotic activity, and perforated mandibular bone with infiltration into adjacent soft tissues. The lymphoid nature of these neoplasms was demonstrated by immunohistochemical and ultrastructural study.
