Abstract
Hidradenitis suppurativa (HS) is a chronic skin condition that can lead to significant morbidity and, in some cases, transformation to squamous cell carcinoma (SCC). This report details the case of a 53-year-old man with a history of HS treatment with adalimumab and systemic antibiotics who developed well-differentiated SCC. For this malignant transformation, the patient required aggressive management, including radiation therapy, wide excision, and reconstructive surgery. Follow-up showed no disease progression. This case highlights the importance of early detection, routine screening, and a multidisciplinary approach in managing the risk of SCC in patients with HS.
