Hydroa vacciniforme mimicking eczema herpeticum: a rare case report

We report case of a 13-year-old male patient with characteristic clinical findings of a rare photodermatoses-hydroa vacciniforme supported by dermoscopy and laboratory investigations. Despite its characteristic presentation, it may mimic other photodermatoses and infectious conditions, making careful clinical assessment essential. Dermoscopy served as a valuable adjunct in reinforcing the diagnosis, especially when biopsy was not feasible. The patient demonstrated rapid improvement with systemic steroids, vitamin D supplementation, sunscreen and strict photoprotection, underscoring the importance of early recognition and appropriate management. Given its rarity, this case adds to the limited literature and emphasizes the critical role of clinical suspicion and dermoscopy in diagnosing hydroa vacciniforme.
