We report a case of a recurrent sclerodermiform basal cell carcinoma (BCC) resulting in an extensive surgical defect involving multiple subunits of the nose, eyelid, and cheek, traditionally requiring complex multistage flap reconstruction, successfully managed with SIH followed by a combination of laser technologies.Case presentation: A 75-year-old male with recurrent sclerodermiform BCC underwent excision resulting in a large facial defect affecting multiple nasal, eyelid, and cheek subunits. The wound was managed with SIH supported by sequential use of advanced dressings. After several weeks, the patient developed a small hypertrophic scar along the lateral nasal sidewall and malar region. A combined protocol using intense pulsed light (IPL), a fractional ablative erbium laser, and 5-fluorouracil (5-FU) drug delivery resulted in progressive remodeling and complete clinical resolution of the hypertrophic component, yielding a nearly imperceptible scar.Discussion: Early postoperative intervention with a multimodal laser approach may significantly enhance cosmetic outcomes following SIH, even in extensive defects involving multiple facial subunits. This case illustrates the potential of combined laser technologies and 5-FU as a minimally invasive strategy to optimize scarring and reduce the need for complex reconstructive surgery.","PeriodicalId":9630,"journal":{"name":"Case Reports in Dermatological Medicine","volume":"2026 ","pages":"9822266"},"PeriodicalIF":0.0,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12954547/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147354005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a case of an 81-year-old male with junctional epidermolysis bullosa, multiple metastatic cutaneous squamous cell carcinomas and a papillary urothelial carcinoma. He was diagnosed with an invasive, high-grade pT2 papillary urothelial carcinoma of the penile urethra at age 74. This was initially identified by the patient as a nonhealing ulcer adjacent to the penile meatus on a background of recurrent blistering of the glans penis. Staging imaging revealed no nodal enlargement or distant metastasis. Management included a partial urethrotomy of the penile urethra, and he is currently in remission. We hypothesise that the urothelial carcinoma may have developed secondary to a permissive tumour microenvironment, which results from chronic inflammation and fibrosis in junctional epidermolysis bullosa.","PeriodicalId":9630,"journal":{"name":"Case Reports in Dermatological Medicine","volume":"2026 ","pages":"5549697"},"PeriodicalIF":0.0,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12927908/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147282366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tuberculosis verrucosa cutis (TBVC), one clinical manifestation of CTB, poses a particular diagnostic challenge, as lesions are often paucibacillary, resulting in negative culture and PCR results. We present the case of a 73-year-old woman with a 10-year history of recurrent skin lesions on her left hand, initially diagnosed as eczema and exacerbated by topical corticosteroid treatment. Despite repeated negative histopathological stains, mycobacterial cultures. and PCR for Mycobacterium tuberculosis, a strong positive QuantiFERON-TB Gold test established the diagnosis. This case emphasizes the diagnostic utility of interferon-gamma release assays (IGRAs) in paucibacillary forms of CTB. Management was complicated by adverse drug reactions (ADRs) to first-line antituberculosis therapy (HRZE), including myalgias, fatigue, and a pruritic rash attributed to pyrazinamide and rifampin. These agents were discontinued, and the patient was transitioned to an alternative regimen, which resulted in improved tolerability and marked clinical improvement. This case highlights the diagnostic pitfalls and therapeutic challenges in managing TBVC. It underscores the importance of maintaining a high index of clinical suspicion for CTB in chronic, verrucous skin lesions, even in patients without specific TB risk factors. It also emphasizes the need for individualized treatment strategies.","PeriodicalId":9630,"journal":{"name":"Case Reports in Dermatological Medicine","volume":"2026 ","pages":"3172006"},"PeriodicalIF":0.0,"publicationDate":"2026-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12893390/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146177895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment approaches usually include skin-directed therapies for early-stage disease and, additionally, systemic therapies for advanced stages. Chlormethine hydrochloride gel is recommended as a first-line treatment option for adult patients with MF, with previous studies demonstrating its efficacy. Due to the rarity of this disease, available literature on the optimal treatment of MF with chlormethine gel is limited, creating challenges for making informed clinical decisions. Thus, we share our individual clinical experiences of selected patients on chlormethine combination treatments to increase the real-world evidence for chlormethine gel in patients with MF.Case presentation: We present the cases of five male and two female Caucasian patients above the age of 48 with Stage I-IV MF, presenting with symptoms of skin plaques and lesions. All patients were treated with chlormethine hydrochloride gel in combination with other skin-directed and systemic therapies, including bexarotene, methotrexate, topical steroids, extracorporeal photopheresis, donor lymphocyte infusion and interferon-α (IFN-α) 2a. In most cases, chlormethine combination treatment resulted in disease control, e.g., plaque reduction, stable disease, and partial or complete response. The combination regimens were generally well tolerated, with associated adverse events being inflammation, pruritus and erythema.Conclusions: This case series reports on the efficacy and safety of chlormethine hydrochloride gel in combination with other topical and systemic therapies in reducing the skin lesion severity in patients with Stage I-IV MF in different real-world settings.","PeriodicalId":9630,"journal":{"name":"Case Reports in Dermatological Medicine","volume":"2026 ","pages":"8813008"},"PeriodicalIF":0.0,"publicationDate":"2026-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12884418/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146156244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absence of any significant trauma and familial predisposition to skin cancer in this patient underscores the importance of considering alternative risk factors. A comprehensive literature review revealed that while sun exposure, scarring, and immunosuppression are established risk factors for finger BCC, our case highlights the potential role of occupational and iatrogenic factors, such as hot oil spillage and HIV, in the pathogenesis of this uncommon malignancy. Notably, the thumb is the most frequent site of finger BCC, with the nodular subtype being the predominant histological variant. Surgical excision, often employing Mohs micrographic surgery, remains the gold standard treatment. In this case, wide excision and dorsal metacarpal artery flap reconstruction were performed. This report expands our understanding of the diverse clinical presentation of BCC and emphasizes the need for a thorough evaluation of potential risk factors in atypical cases.","PeriodicalId":9630,"journal":{"name":"Case Reports in Dermatological Medicine","volume":"2026 ","pages":"9392963"},"PeriodicalIF":0.0,"publicationDate":"2026-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12860216/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146103487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The serum displayed antibasement membrane autoantibodies that reacted with monkey esophagus tissue, and immunofluorescence revealed that the patient was positive for antineuronal antibodies that reacted with mouse brain tissue. The molecular reactivity of the serum and fluid obtained from a bulla was positive for the BP180-Ag2 antigen, as determined by ELISA.
