Cases of gout involving the nail unit are likely under-recognized and therefore underreported. We present two cases of tophaceous gout affecting the nail unit and a literature review of the various presentations. Summary: Five cases of gout were identified to affect the nail unit. In all cases, these presented as white hyperkeratotic papulonodules with associated nail dystrophy. Chalky discharge was seen in three of the five cases. Nine cases were identified to have demonstrated pseudocarcinomatous changes that histopathologically mimic squamous cell carcinoma (SCC). Literature review highlights a range of findings including subclinical deposits of uric acid in the nail, onychoschizia, onychorrhexis, and Beau’s line. Key Messages: Physicians should be aware of the subtle and nonspecific clinical findings of gout, which may be easily misconstrued for other pathological entities.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"178 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139251160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presenting more frequently in the fingernails, common risk factors include ionizing radiation, oral exposure to arsenic or pesticides, dyskeratosis congenita, and quite commonly diverse subtypes of HPV. We report the first case of multiple periungual pigmented Bowen’s disease in a pediatric patient. Case Presentation: A healthy 13-year-old boy presented with a 9-month history of a pigmented erythematous patch on the proximal nail fold of his 3rd right finger without associated symptoms. A punch biopsy was taken, and the diagnosis of Bowen’s disease was made. The patient received photodynamic therapy and three cycles of imiquimod without response, and two new lesions appeared on the first and second right fingers. Surgical removal was performed on all lesions. A polymerase chain reaction detected an HPV type 16. Discussion/Conclusion: Multiple periungual Bowen’s disease is rare, with the most frequent risk factors being HPV infection and chronic immunosuppression. Less than 10% of the cases present as longitudinal melanonychia. To date, there are no previous reports of multiple pigmented periungual Bowen’s disease. HPV-induced Bowen’s disease is usually present in adults aged between 22 and 89 years as persistent verrucae. In this case, koilocytosis and the fact that all lesions appeared on the right hand are suggestive of HPV infection.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"56 9","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139257979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method: A retrospective observational study was conducted based on clinical records from HS patients followed at a tertiary hospital, with diagnosis between January 2006 and December 2022. Results: A total of 285 patients were included. The mean diagnostic delay was 10.1 years, and there was no difference in time to diagnosis during the considered period. A diagnostic delay of more than 5 years was significantly associated with an earlier onset of symptoms, location on breasts and thighs, follicular phenotype, and with cardiovascular and psychiatric comorbidities. Smoking and body mass index ≥25 kg/m2 were also associated with a longer diagnostic delay. A personal history of acne and a greater disease severity were associated with an earlier diagnosis.
