Concomitant lip and vulval involvement of Crohn's disease: A rare occurrence.

Crohn's disease is a chronic granulomatous inflammatory condition affecting any part of the gastrointestinal tract. Extra-intestinal manifestations affecting the mouth may also occur, with a prevalence varying between 0.5% and 37%. However, vulval involvement is rare with approximately130 reported cases in the literature so far. An extensive literature search has shown isolated lip and vulval involvement as extra-intestinal manifestations of Crohn's disease, with only one reported case of combined vulval and lip involvement.
