Vulvite granulomateuse de type Miescher

Miescher's granulomatous vulvitis requires differential diagnosis, essentially with regard to Crohn's disease. Our case illustrates the difficulty in diagnosing this rare disease as well as the uncertainties surrounding its physiopathology. Diagnosis rests upon repeated sampling and biopsies with repeated levels of sections in order to identify the characteristic perivascular granulomas, which may be very mild.
