Lipomatosis has not previously been reported in minor salivary glands. Its occurrence in the parotid gland is well recognized. We present the first reported case of lipomatosis of the minor salivary glands in the nasal cavity. We also review the tumours of the minor salivary glands, lipomas and lipomatosis of the parotid, and the few reported cases of lipomas of the sinonasal tract.

Canalicular adenoma is a recently classified uncommon salivary gland neoplasm. This biologically benign growth tends to be multifocal and occurs most often in the upper lips of elderly people. Histologically and clinically it differs from the basal cell adenoma, for which it may be mistaken, in a number of ways. Its clinical importance lies in the fact that it may be confused with malignancy. Little information is available regarding the recurrence and long-term follow-up of these tumours, and where available it covers only relatively short periods.We report the recurrence of a canalicular adenoma after an 11.2 year disease-free period.

Malignant mesothelioma (malignant adenomatoid tumour) of the tunica vaginalis testis is a very rare neoplasm with highly aggressive biological behaviour. Treatment is difficult, and widespread local invasion and/or metastatic disease at presentation are associated with a poor prognosis. In this case report we describe for the first time a patient who, despite presenting with locally advanced disease, remains well 10 years after diagnosis and treatment with radical orchidectomy and high dose radiotherapy.
