Teen misdiagnosed with muscle ache later found to have rare spindle cell sarcoma; underwent pioneering tibia surgery
Now 32, Gracie Butler survived aggressive treatment, multiple complications and sepsis, later giving birth and becoming a hospice volunteer after support from the Teenage Cancer Trust
An 18-year-old woman was diagnosed with a rare and aggressive cancer after doctors initially dismissed her leg pain as a muscle ache, treatment notes show. Gracie Butler, now 32, was told she had a spindle cell sarcoma after presenting to hospital unable to walk; physicians later warned she might lose her leg and face reduced fertility as a result of the disease and its treatment.
Butler first sought medical help when she began experiencing pain in her leg and was given diagnoses of muscle ache and later tendonitis. The pain persisted despite physiotherapy and topical treatments, and following a night out she woke unable to walk. Hospital imaging and a biopsy led to the diagnosis of spindle cell sarcoma, a rare cancerous tumour, and rapid treatment followed.
Clinicians immediately started Butler on a high-dose chemotherapy regimen and discussed the risk that she might not be able to keep her leg. There was insufficient time to preserve eggs before treatment, leaving Butler and her family concerned about future fertility. She spent several weeks in hospital during chemotherapy and suffered infections that complicated her recovery.
Four months after her diagnosis, surgeons removed Butler’s tibia — the shinbone — in a procedure that exposed the bone to radiation to kill cancerous cells before returning it to her leg and securing it with metal plates. The operation was described by Butler as "ground-breaking," but the recovery was prolonged and difficult. The 20-centimetre surgical wound repeatedly failed to close, recurring infections deepened the wound, and chemotherapy side effects included skin damage and internal ulcers.
Doctors paused chemotherapy briefly to allow Butler’s body to recover and resumed treatment about a month later. Despite completing treatment six months after it began, she subsequently battled sepsis and required multiple additional surgeries and physiotherapy to address ongoing problems in the affected leg.
Butler later gave birth to a son, Roux, in 2015 while still in a leg frame. Medical notes indicate that her pregnancy came after an "aggressive course" of chemotherapy that had produced menopausal symptoms and made childbirth unlikely, according to Butler's account. She described her son as a "miracle" and said she is grateful to be able to parent him.
In the years since her diagnosis and treatment, Butler has returned to day-to-day life and taken on volunteer work. She is now a volunteer manager at Rotherham Hospice and has spoken about the role that specialised services for young people with cancer played in her care. Butler credited the Teenage Cancer Trust with providing support during her treatment and said time spent in a dedicated unit created important family memories during a difficult period.
Spindle cell sarcoma is considered a rare and aggressive form of soft-tissue cancer. Treatment typically involves a combination of surgery, radiation and chemotherapy tailored to the tumour’s location and biological characteristics. In Butler’s case, clinicians used an approach that combined surgical resection with intraoperative radiation aimed at eradicating tumour cells in the removed bone before reimplantation.
Butler said the experience shaped her perspective and left her appreciative of surviving and of continuing to parent her son. She noted ongoing limitations in mobility but reported that her leg now functions and that she values the support she received while young and hospitalized. Medical teams involved in her care have highlighted the complexity of diagnosing rare tumours in younger patients whose initial symptoms may resemble benign musculoskeletal conditions.
Her case underscores both the clinical challenges of identifying uncommon malignancies and the potential for long-term survival after intensive, multidisciplinary treatment. Butler’s experience also highlights the emotional and practical consequences of rapid treatment decisions on fertility and the importance of supportive services for adolescents and young adults facing cancer.
