A rare case of primary forearm flexor-pronator muscle group chromoblastomycosis

Chromoblastomycosis is the infection of cutaneous and subcutaneous tissues. It can disseminate to distant tissues secondarily by hematogeous and lymphatic routes. In our search of the literature, we found only one case that showed involvement of the underlying bone. In this paper, we report an unusual case in which cutaneous chromoblastomycosis involved the flexor-pronator muscle group in the forearm, which presented as a stiff elbow. This case occurred in northeastern India, which is not endemic for this infection.
