Granular cell tumor of the larynx in children: a case report (original) (raw)

Granular cell tumor of the esophagus

Saudi medical journal, 2003

Reports on esphageal granular cell tumor are relatively rare. Recently we have experienced two cases of esophageal granular cell tumor removed by endoscopic polypectomy. Both were females, 58 and 54 year-old, respectively, and without tumor-related complaints. Diagnosis was made by esophagogram and endscopic biopsy specimens. The two patients were treated with endoscopic polypectomy. To our knowledge 59 cases of this tumor were reported in literatures in Japan and the present cases were 60th and 61th respectively. The symptoms and management of esophageal granular cell tumors were discussed.

A Clinical Study of Pharyngeal Small Cell Carcinoma

Nippon Jibiinkoka Gakkai Kaiho, 2017

Extrapulmonary small cell carcinoma arising from the pharynx is rare. We have experienced 4 cases of pharyngeal small cell carcinoma. All the patients were male, and the mean age was 66 years old. The primary site was the oropharynx in 2 cases and the hypopharynx in 2 cases. All the patients initially underwent surgical resection, followed by chemotherapy or chemoradiotherapy. Three patients died because of distant metastasis. One patient is still alive without disease. Twenty four cases of pharyngeal small cell carcinoma have been reported to date. An analysis of these 28 cases, including our 4 cases, revealed that 20 of the cases had died because of pharyngeal small cell carcinoma. Thus, pharyngeal small cell carcinoma appears to be associated with a relatively poor prognosis similar to that of pulmonary 120 831 small cell carcinoma. Patients with T3/4 or metastatic diseases have an especially poor prognosis. When the primary site is resectable with minimum invasion, surgery followed by chemotherapy or chemoradiotherapy might offer a better chance of inhibiting local recurrence, compared with other strategies.

Laryngeal regeneration using tissue engineering techniques in a canine model

The Annals of otology, rhinology, and laryngology, 2011

We previously reported that polypropylene mesh covered with collagen sponge is a useful material for the regeneration of the trachea and the cricoid cartilage. The aim of this study was to regenerate larynges after partial hemilaryngectomy with this new biomaterial. A left partial hemilaryngectomy was performed on 12 adult beagles. The defect size was about 1.8 x 1.0 cm. Both sides of polypropylene mesh were coated with either 1% or 3% collagen sponge. This scaffold was wrapped in fascia lata harvested from the left thigh and then fixed in place over the defect. Endoscopic examinations were performed periodically. Six months after treatment, 3-dimensional computed tomographic scanning was performed. Vibratory examinations were also performed with excised larynges. In the 1% collagen group, exposure or dislocation of the mesh was found in 3 of 6 cases, but in the 3% group, no exposure of the mesh was seen. The morphological findings in the vocal fold were better in the 3% group than ...
