[Macrocheilia, granulomatous cheilitis and Crohn's disease].

Granulomatous cheilitis is a rare disease included among the orofacial granulomatoses. It is characterized by a idiopathic chronic inflammation of the labial mucosa (macrochelia), which takes the form of episodic and progressive outbreaks. In 10% of patients, it is associated with Crohn's disease. We report the presentation, evaluation and treatment of a case of granulomatous cheilitis which appearted two years after the onset of Crohn's disease. We conclude that granulomatous cheilitis is rare in children, with few reported cases, although probably underdiagnosed because of lack of awareness. The diagnosis of granulomatous cheilitis is clinical, although the histological evaluation is a determining factor. After making the diagnosis a comprehensive assessment of the patient is recommended, to rule out the other associated syndromes described in the literature.
