A case of nodular type lipomatosis arising from both borders of the tongue is reported. The patient was a 72-year-old man who presented with multiple nodules arising bilaterally from the margin of the tongue. The nodules were elastic and soft, and the mucosa of the tongue surface was normal. Excisional biopsy was performed on the right-side nodules. The left-side nodules were extirpated 9 months after the excisional biopsy on the right side. The histopathological diagnosis was lipomatosis. There has been no sign of recurrence as of 1 year after surgery. The patient had a history of alcoholic hepatitis, hypertension, hyperlipidemia, and hyperuricemia. Lipomatosis of both borders of the tongue was suggested to be associated with local factors (e. g., teeth, bite occlusion, trauma) and systemic disorders (e. g., alcoholism, liver dysfunction, hyperlipidemia).

An 82-year-old woman was referred to Tokai University Hospital because of swelling of the upper jaw. Biopsy was performed, and the diagnosis was squamous cell carcinoma. Because she had coronary artery disease, percutaneous transluminal coronary angioplasty (PTCA) was performed before surgery for the upper gingival cancer. Consequently, surgery was able to be performed without perioperative cardiac complications. However, coronary restenosis occurred 1.5 months after PTCA, and an intracoronary balloon-expanded stent was inserted at the site of restenosis.Currently, there has been no local tumor recurrence and no angina pectoris.

A 56-year-old woman presented to our clinic with a mass in the floor of the mouth. This patient had been given a diagnosis of sleep apnea syndrome at the Department of Respiratory Disease of our hospital. The body mass index was 34.4, indicating slight obesity, and the apnea hypopnea index (AHI) was 38.2/hr. Oral examination revealed a bony eminence arising bilaterally from the mandible anterior to the tongue and extending to the premolar region.After resecting the mandibular eminence, the AHI improved to 20.9/hr. However, since sleepapnea persisted, control of obesity by weight reduction was considered necessary.
