Resolution of granulomatous rosacea after eradication of Helicobacter pylori with clarithromycin, metronidazole and pantoprazole.

The aetiopathogenetic role of Helicobacter pylori in rosacea remains controversial. We report a 27-year-old man with a 4-year history of intractable rosacea. Histopathology showed epithelioid granulomas. H. pylori infection was proven directly on gastroscopy and by serological testing. Treatment with clarithromycin, metronidazole and pantoprazole eradicated H. pylori. Skin changes were markedly improved by the end of this therapy and had resolved completely 2 months later. The patient has been followed up, and has remained free of symptoms for 3 years. We suggest that H. pylori may be involved in the aetiopathogenesis of granulomatous rosacea.
