title: Remission of pustular psoriasis after cholecystectomy: role of focal infection in pustularization of psoriasis.
abstract: We report an 81-year-old male with long lasting psoriasis with exacerbation who showed remission of skin lesions after cholecystectomy. He consulted our clinic for impetiginous skin lesions and was treated with oral antibiotics without improvement. Several days later, he developed right hypochondralgia and was diagnosed with acute cholecystitis with gallstones. After cholecystectomy, the skin lesions significantly improved and disappeared within three weeks. Laboratory examination data indicated that acute inflammatory parameters normalized simultaneously. Although the role of focal infection in psoriasis is obscure, our case emphasizes the importance of focal infection in the pathogenesis of unstable psoriasis.
