[Maxillary ameloblastoma. Illustration apropos of a clinical case].

The authors report a case of maxillary ameloblastoma presenting as nasal obstruction. An histopathologic description is done. The difference of clinical course between intra-osseous and extra-osseous (peripheral) ameloblastoma are recalled. The desmoplatic histologic type, recently described in medical literature, is exceptional. Surgery remains the adapted treatment in most cases.
