Palisaded neutrophilic granulomatous dermatitis associated with Sjögren's syndrome.

This article discusses a case of palisaded neutrophilic granulomatous dermatitis (PNGD) associated with Sjögren's syndrome (SS). The patient, a 66-year-old woman, presented with recurrent edematous erythema on her trunk and limbs. Histopathological examination confirmed the diagnosis of PNGD. The patient also had a history of dry mouth and difficulty swallowing, and further testing revealed positive immune antibody indicators for SS. After treatment with medication, the patient's symptoms improved. The article highlights the rarity of PNGD in patients with SS and suggests a possible link between the two conditions. The study was conducted by a team of researchers and was supported by various funding sources. [Extracted from the article]
