Granulomatous Rosacea or Tuberculid, A Histopathological Dilemma.

Abstract

Rosacea is a chronic hyperaemic disease of the skin involving the flush area of the face. It is characterized by persistent erythema and often by telangiectasia with acute episodes of oedema, papules, and pustules. It tends to occur more commonly in females between the ages of 30 and 50 years, but it follows a more severe course in males leading to formation of rhinophyma, gnathophyma, etc. Ocular involvement is the most serious complication and can cause conjunctivitis, blepharitis, episcleritis, iritis, and keratitis. Granulomatous rosacea is an atypical variant, characterized by papular and occasionally granulomatous lesions, which on diascopy appear as yellowish brown nodules and on histopathology exhibit epithelioid cell granulomas [1]. We present here one such case.
