DefinitionThis section has been translated automatically.
Very rare, localized, chronically recurrent, neutrophilic (pustular) dermatosis that manifests mainly in the large flexures of the axillae, the groin and possibly also perianally as well as on the digital acras or capillitium. After a longer period of persistence, extensive erosive plaques develop.
Associated autoimmune diseases have been described as:
- systemic lupus erythematosus
- antiphospholipid syndrome
- Crohn's disease
- Hashimoto's thyroiditis (Wang MZ et al. 2017).

Occurrence/EpidemiologyThis section has been translated automatically.
w:m=9:1; very rare; <100 cases have been reported so far (Schissler C et al. 2017)
LocalizationThis section has been translated automatically.
Large joint flexion (axillary, inguinal), capillitium, external auditory canals, anogenital, navel
Clinical featuresThis section has been translated automatically.
In young women, development of localized therapy-resistant, sterile pustulosis in the area of the large joint flexures. After prolonged persistence, erosive weeping red plaques develop. The clinical appearance changes with the site of infection (auditory canal: erosive otitis externa), capillitium (pustular, weeping dermatitis), digital acra (purulent paronychia with consecutive onychodystrophy).
HistologyThis section has been translated automatically.
Cancellous dermatitis with the formation of (sterile) pustules and an inflammatory infiltrate of neutrophil granulocytes, lymphocytes and macrophages that reaches the middle corium. Discrete signs of vasculitis. In 30% of the cases, evidence of a lupus band at the dermo-epidermal junction.
TherapyThis section has been translated automatically.
Immunosuppressive (glucocorticoids, cyclosporin A); still successful in individual cases: Anakinra; TNF-alpha-blocker.
