Angioleiomyoma of the cheek: a case report.

Angioleiomyoma is a form of subcutaneous vascular leiomyoma that usually occurs in the extremities. Leiomyoma of the oral cavity represents only 0.4% of soft tissue neoplasms and 0.06% of leiomyomas. Isolated cases of angioleiomyoma have been reported in the knee and lower thigh, gastrointestinal tract, genital and renal tract, and brain. Histopathologic examination by biopsy is necessary to establish a diagnosis, and immunohistochemical staining, along with conventional hematoxylin-eosin staining, is important. The differential diagnosis includes hemangioma and angiosarcoma. At present, surgical resection is the standard therapy for leiomyoma, and recurrence is extremely rare. We report a rare case of angioleiomyoma of the cheek in a 45-year-old man. The postoperative course was uneventful, without complications.

[Clinical effects of concurrent chemoradiotherapy (hyperfractionation and cisplatin/5-fluorouracil) for patients with advanced oral squamous cell carcinoma].

Six patients with advanced oral squamous cell carcinoma were treated with preoperative concurrent chemoradiotherapy. Chemotherapy consisting of CDDP(60 to 70 mg/m(2), day 1)and 5-FU(600 to 700 mg/m(2), day 1 to 5)with concurrent radiotherapy was accelerated hyperfractionation to target volume of 43-63 Gy. The clinical effect of this therapy on the primary tumor and cervical lymph node was examined in patients who visited our university hospital from 1994 to 2004. The five untreated and one recurrence patients were 3 males and 3 females. Their ages ranged from 23 to 76 years. The primary sites were the tongue in 3, lower gingiva in 2, and upper gingiva in 1 patient(s). Five cases were in advanced Stage IVA and 1 case in Stage III. The preoperative clinical responses of primary tumor: 1 case showed a complete response(CR). The response rate was 100%. We did not operate the case because of CR. Histological effect of the primary tumor(according to the grading system of Ohboshi and Shimosato): 2 patients were CR. Pathological CR rate of primary site was 33%. However, the CR rate of the metastatic lymph nodes was 0%. In terms of adverse effects, all cases developed nausea, mucositis and leucopenia. The most severe were leucopenia(Grade III), sepsis and DIC. This combination chemoradiotherapy has been proven to be very histologically effective for the primary tumor.

Calcium pyrophosphate dihydrate arthropathy with condylar destruction of the temporomandibular joint.

We report a case of calcium pyrophosphate dihydrate (CPPD) arthropathy with condylar destruction of the temporomandibular joint. Diagnosis was made on the basis of clinical findings and x-ray evidence of severe destruction of the condyle. The most likely diagnosis was considered to be neoplasm and a secondary infection of the left TMJ. Review of sections of the condyle taken at operation confirmed the diagnosis of left TMJ pseudogout. The postoperative course was uneventful with improvement in the clinical symptoms.
