[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.

A pseudo-tumoral form of Kikuchi's disease in children: a case report and review of the literature

We report one case of a cervical pseudo-tumoral form of histiocytic necrotizing lymphadenitis (Kikuchi Fugimoto disease) occurring in a 13-year-old child. Diagnosis was made only by histology examination of an excision biopsy from one cervical lymph node. Spontaneous complete resolution occurred within 2 months. A review of the clinical and histological features in adults and children is presented. No difference was found between the two populations regarding these features. Differential diagnoses are malignant lymphoma, systematic lupus erythematosus and, in particular, Still's disease in children. The etiology of the disease is also discussed.
