Metastatic arthritis is uncommon. The knee is the most affected joint. Arthritis can either be secondary to direct tumor invasion of the synovial membrane or reaction to a juxta articular bone location. The primary tumor is often a lung cancer and histological type is mainly adenocarcinoma. We report a case of knee monoarthritis secondary to joint metastases of cutaneous squamous cell carcinoma. The diagnosis was suspected in front of recurrent haematic arthritis, preceded by skin ulceration, evolving in a context of deterioration of the general status. The diagnosis was confirmed by comparable anatomopathological results of bone and synovial biopsy on the one hand, and biopsy of the skin ulceration on the other.
