Condylar hyperplasia (CH) is a pathologic condition that causes overdevelopment of the condylar head and neck as well as the mandible. Slowly progressive unilateral enlargement of the head and the neck of the condyle causes crossbite malocclusion, facial asymmetry, and shifting of the midpoint of the chin to the unaffected side. The etiology and the pathogenesis of CH remain uncertain. The diagnosis is made by clinical and radiologic examinations and bone scintigraph. A difference in uptake of 10% or more between condyles is regarded as indicative of CH, and the affected condyles had a relative uptake of 55% or more. When the diagnosis of active CH is established, the treatment consists of removal of the growth center by a partial condylectomy. The authors present the case of a 46-year-old male patient with right active type II CH or hemimandibular hyperplasia who underwent a high condylectomy.

The plasma cell neoplasms may present in soft tissue as extramedullary plasmacytoma (EMP), in bone as a solitary plasmacytoma of bone (SPB), or as part of the multifocal disseminated disease multiple myeloma (MM). The EMP is rare, comprising around 3% of all plasma cell neoplasm. The majority (80%) occurs in the head and neck region. In this study we report a case of a man, 70 years old, melanoderm, with a lesion of the oral cavity. Upon physical examination, a lesion was found that extended throughout the posterior upper alveolar ridge, as far as the maxillary tuber on the left side, extending towards the palate. Radiographic examination, complementary laboratory exams were performed. Based on the conclusive symptoms of plasmacytoma, the patient was referred to the hematology service for treatment with local radiotherapy. The patient responded satisfactorily to the treatment, and after 15 months, all clinical symptoms of the lesion in the oral cavity had disappeared.
