[Bony involvement of the calcaneum in sarcoidosis. A case report]. / Atteinte osseuse du calcanéum au cours de la sarcoïdose. A propos d'un cas.

Bone lesions of sarcoidosis occur in 10 to 15% of the cases, most often involving the extremities. These frequently corticosteroid-dependent lesions worsen the prognosis of the disease. We report a case of sarcoidosis of 14 years duration in a 58-year old woman who presented with a bone lesion strictly localized to the calcaneum. To our knowledge, such lesion has not previously been reported.
