[Rheumatism and acne conglobata . Apropos of a new case, in a 13-year-old boy].

With reference to a new case of acne conglobata-associated rheumatic disease in a thirteen-year-old boy, we recall the characteristics of the main joint and/or bone manifestations that may occur during severe flares of acne conglobata, but also acne fulminans or pustulosis of the palms and soles. Joint manifestations mainly involve the large proximal joints of the limbs and consist in pain rather than in signs of inflammation. Although recurrences may develop, joint disease responds to treatment of the acne combined with a non-steroidal antiinflammatory drug.
