Post-Traumatic Extensive Scalp Ulceration: A Diagnostic and Management Challenge!

Dissecting cellulitis of scalp (DCS) is an uncommon inflammatory dermatosis, which can be difficult to diagnose in the absence of concomitant cutaneous markers. We present an interesting case of DCS in a 60-year-old male, with an onset after blunt trauma to head. The progression was fast and diagnosis could be achieved on multiple biopsies only. The response to therapy with a combination of oral isotretinoin and intralesional triamcinolone acetonide injections is highlighted in this difficult to treat dermatoses.
