[Nasal endometriosis: apropos of 1 case]

The nasal mucosa is an exceptional localization for endometriosis. We report a case observed in a woman who developed nasal tumefaction associated with epistaxis that had followed a cyclic repetitive pattern since puberty. Surgical excision of the nasal nodule confirmed the diagnosis of endometriosis. Local and general evaluated identified other localizations. Outcome has been favorable at short and mid term. Endometriosis is a frequent condition although extra-pelvic localizations are uncommon. The nasal localization is highly exceptional.
