A 43-year-old man suffered from migrating then additive arthralgias associated with macroscopic and microscopic cutaneous lesions compatible at first sight with reticular erythematous mucinosis. After nine months, the cutaneous picture evolved into a papular mucinosis. The patient developed "multiple frozen joints" with heterotopic bony deposits around the hips. To our knowledge, such articular problems have not yet been described in this condition. Severe systemic complications prompted the authors to treat the patient with plasma exchange and melphalan.
