Polymicrobial pyogenic flexor tenosynovitis of the index finger and first ray resulting from autophagia.

Pyogenic flexor tenosynovitis (PFT) is a well known infectious condition of the hand, involving the inoculation of the flexor tendon sheath with microorganisms. Many cases have been reported, common causes including direct inoculation by a puncture wound and deep lacerations extending into the flexor tendon sheath. In this report, we present a case of a 50 year old female with PFT resulting from autophagia (consuming one's own body parts, in our case, fingers) successfully treated with irrigation and debridement, amputation of the index finger at the metacarpophalangeal joint and antibiotic therapy.
