Symmetric Lipomatosis Arising in the Tongue Presenting as Macroglossia and Articulatory Disorder.

Symmetric lipomatosis is definitively characterized by symmetric, tumorous lipomatous proliferation of adipose tissue that often develops in the head and neck, shoulders, and upper trunk. However, in the oral region, symmetric lipomatosis of the tongue (SLT) is an extremely rare condition related to generalized lipidosis that is often caused by chronic alcoholism. It is characterized by multiple symmetric lipomatous nodules and diffuse bilateral swelling located within the tongue.

Massive odontoameloblastoma arising in the maxilla: a case report.

Introduction: Odontoameloblastoma is an extremely rare mixed odontogenic tumor with both epithelial and mesenchymal components. The term odontoameloblastoma first appeared in the 1971 World Health Organization classification (Pindborg JJ., et al.

Massive Neurilemoma of the Hard Plate in Which Preoperative Diagnosis Was Difficult.

The patient was an 84-year-old man who was referred to our hospital in mid-December 2012 for a close examination of a mass arising from the left side of the hard palate that was found by a local dentist. The initial examination revealed the presence of a 3.0-cm elastic soft, dome-shaped mass in the left hard palate.

Methotrexate-associated lymphoproliferative disorder arising in the retromolar triangle and lung of a patient with rheumatoid arthritis.

We report an extremely rare case of massive methotrexate-associated lymphoproliferative disorder (MTX-LPD) arising in the retromolar triangle and lung of a patient with rheumatoid arthritis. The patient was a 75-year-old woman who was referred to our department because of severe pain associated with a unilateral ulcer on the left retromolar triangle. The tumor had an extranodal location in the retromolar triangle and in the right lung.

A case of Basal cell adenoma of the upper lip.

Basal cell adenoma is a rare type of benign salivary gland tumor found most commonly in the parotid gland. We present a rare case of basal cell adenoma arising in the minor salivary gland of the upper lip. The patient was a 59-year-old Japanese man who visited our department in December 2012 with a chief complaint of a mass in the upper lip, which had increased in size over several years.

Epidermoid cyst arising in the submandibular region.

Dermoid and epidermoid cysts in the oral cavity frequently develop in the midline or sublingual region of the floor of the mouth. Here, we report a rare case of an epidermoid cyst in the submandibular region. The patient was a 69-year-old man with a chief complaint of a mass in the right submandibular region.

[Longitudinal assessment of articulatory and masticatory functions following glossectomy for tongue carcinoma].

The functions of articulation and mastication after glossectomy for tongue carcinoma were sequentially assessed. Longitudinal assessment of articulatory and masticatory functions was analyzed in 64 tongue cancer patients who underwent partial glossectomy (partial glossectomy group: 40 cases) or hemiglossectomy (hemiglossectomy group: 24 cases) in our department between January 2007 and August 2008. The mean age of the 64 patients (37 men, 27 women) was 56.
