Sjoren syndrome favors the development of lymphoma, particularly in the salivary glands with MALT lymphomas. The differential diagnosis with benign lymphoepithelial sialadenitis can be difficult. A 78-year-old woman had an oculo-buccal sicca syndrome for 10 years and developed parotid hypertrophy. The first biopsy, performed 7 years before the present investigation had showed chronic lymphoepithelial sialadenitis. A second biopsy showed MALT lymphoma. Search for extension revealed a second gastric localization of the lymphoma. This patient had a particular immunophenotype, showing a CD5+ tumoral population frequently observed in mantel lymphomas and usually lacking in MALT lymphomas. Recently, however, another case similar to our own, has been reported in the literature. The observations raise the problem of distinguishing between mantel lymphoma and MALT lymphoma.

We present five cases of florid osseous dysplasia observed in our department. There has been some confusion as to the terminology of this entity. We present here a review of the literature and outline the histological classification among odontogenic tumors as well as their epidemiology. The orthopantomogam is the mainstay radiological exploration, sometimes in association with a CT-scan. There are three main differential diagnoses: Paget's disease, Gardner's syndrome located in the maxillofacial area and diffuse sclerosing osteomyelitis. Asymtomatic forms motivate therapeutic abstenstion. When inflammatory, infectious or morphological complications appear, treatment relies on surgery in combination with long-term antibiotic regimens.
