Abstract
Aims Soft tissue sarcomas (STS) of the foot and ankle are rare tumours. The aims of this study were to examine the presenting features and highlight those associated with a delay in diagnosis.
Methods Patients presenting during a 10-year period were identified using a computerised database within the Orthopaedic Oncology Unit at the Royal Orthopaedic Hospital, Birmingham, UK. Additional information was obtained from a systematic case note review.
Results 1519 patients were treated for STS of which 87 (8.2%) had tumours sited in the foot and ankle. Of these, 75 (86.2%) had presented with a discrete lump (56% of them having an inadvertent whoops excision biopsy), 3 (3.4%) with ulceration and the remaining 9 (10.3%) with symptoms more commonly associated with other benign foot and ankle pathology. The 9 had previously been treated as plantar fasciitis (3), tarsal tunnel (2), Morton’s neuroma (1) and none specific hind foot pain (3). Median delay from onset of symptoms to diagnosis as STS was 26 months for this group (mean 50; range 6–180 months) compared to 12 months (mean 32; range 3–240) for the “whoops biopsy group and 10 months (mean16; range 2–60 months) for the unbiopsied discrete lump group.
Conclusion Soft tissue sarcoma in the foot and ankle may present insidiously and with symptoms of other benign pathologies. Failure to respond to initial treatment of suspected common benign pathology should be promptly investigated further with an MRI scan.
