Trismus-pseudocamptodactyly syndrome is a rare neuromuscular disorder that manifests as a combination of hand, foot, and mouth anomalies. Limited range of motion for hands, feet, and mouth are typical presentations. A male term newborn baby was noted to have trismus, ulnar deviation of both wrist joints, limited stretch of digits during hand dorsiflexion but with full digital extension during volarflexion, and talipes equinovarus of the right foot. These anomalies were not seen in his parents. Hecht syndrome, or trismus-pseudocamptodactyly syndrome, was diagnosed with a negative result of electromyographic study.
