Phymatous rosacea

**Definition:** The hallmark of phymatous rosacea is rhinophyma but the forehead, chin and ears may also be affected. It is characterised by hypertrophy of the affected tissue which can produce gross distortion, particularly of the nose. The pathological changes include a variably severe mixed inflammatory infiltrate, sebaceous gland hyperplasia and dermal fibrosis. The aetiology is poorly understood. It is not always accompanied by other features of rosacea.
