Synovial Sarcoma in the Foot of a 5-Year-Old ChildA Case Report.

The purpose of this case report is to present a rare finding of synovial sarcoma in a 5-year-old child. Most soft-tissue masses of the foot are too often presumed to be small and benign; therefore, compared with soft-tissue sarcomas, they are difficult to clinically differentiate and treat. A 5-year-old girl presented with a painful lesion that was diagnosed as synovial sarcoma after an excisional biopsy was performed. This was an unexpected finding of synovial sarcoma involving the tibialis posterior tendon of her right foot. The patient presented with an 8-month history of tenderness and an antalgic gait. We would like to encourage that all soft-tissue tumors of the foot be preoperatively evaluated with the aid of diagnostic imaging so that a well-planned biopsy assessment can be performed, with adequate margins excised.

Absence of the fourth tendon of the flexor digitorum brevis muscle: a cadaveric study.

UNLABELLED: This study was undertaken to help confirm the percentages concerning the presence or absence of the flexor digitorum brevis muscle tendon to the fifth toe. We also hope to be able to determine the presence based on gender and nationality. It is known to be absent occasionally; however, there is no definitive study dedicated to its prevalence. Using a pool of 60 cadavers, 97 total feet were included in our analysis. Of these feet, 47 (48%) lacked a flexor digitorum brevis tendon to the fifth toe at all. Furthermore, 25 (26%) had notably small tendons to the fifth toe. The final 25 (26%) had what the researchers deemed present tendons. This information could be helpful in surgical planning, including tendon transfer techniques, and biomechanical evaluations. Further research would need to be conducted as this was a cadaveric study. LEVELS OF EVIDENCE: Cadaver/anatomy research, Level V.
