title: Scrofuloderma from the acromioclavicular joint presenting as a chronic ulcer in an immunocompetent host.
abstract: A 53-year-old woman presented with a chronic, non-healing painless ulcer over her right clavicular area of a two-month duration. Skin biopsy, microbiological and radiological investigations confirmed the diagnosis of scrofuloderma arising from an underlying tuberculous infection of her acromioclavicular joint. She was treated successfully with anti-tuberculosis therapy with complete healing of the ulcer. Awareness of this uncommon presentation of osteoarticular tuberculosis may assist in earlier diagnosis.
