Chronic occupational paronychia secondary to digital pilonidal sinus from dog grooming.

Abstract

Objectives Pilonidal sinus is a recognized occupational condition sometimes seen in barbers and pet groomers, and it involves most commonly interdigital spaces. We present a previously unreported case of chronic paronychia with two separate digital pilonidal sinuses resulting from multiple embedded hair fragments in the eponychium of a dog groomer, who had been repeatedly treated with antibiotics with no success and ended up to surgical treatment. The objective of this study is to remind readers of this rare but possible occupational disease, particularly among employees working with hair, and to emphasize the importance of preventive measures to prevent its occurrence. Case Presentation Intraoperatively, a crescent of eponychia skin parallel to the proximal nail fold was excised, which incorporated the sinuses. Additionally, the nail plate was removed, and multiple hair fragments were retrieved from the nail folds. At the follow-up, the infection had resolved, and nail growth had resumed. Additional animal hair was found in the nail folds, as the patient continued to work without protective gloves. Conclusions This case highlights the importance of considering embedded hair as a potential cause for chronic paronychia in individuals with occupations involving hair cutting and grooming. Chronic hand infection poses a risk of contaminating infection to clients or patients, e.g., a veterinarian cannot operate on an infected hand. The costs of sickness absences are considerable for all the stakeholders. The use of protective gloves, hand hygiene, skin care, and thorough removal of loose hair fragments should be emphasized for workers in professions dealing with animal or human hair.
