Sporadic Desmoid Tumor Mimicking Myofascial Pain Syndrome in a Chiropractic Clinic.

Chiropractors are primary healthcare providers who diagnose and manage various health conditions, including rare cases like desmoid tumors. Desmoid tumors are locally aggressive soft-tissue tumors originating from fibroblasts. This report presents the case of a 30-year-old woman who initially sought chiropractic care for persistent neck pain that was later discovered to be a symptom of a sporadic desmoid tumor. The patient presented with severe right upper neck pain, which was diagnosed as myofascial pain syndrome and yielded no significant improvement after various treatments. Physical examination by a chiropractor revealed a soft-tissue mass in the right upper trapezius and rhomboid region. In addition, magnetic resonance imaging revealed an intramuscular lesion measuring 8 × 4 cm in the right rhomboids, and subsequent biopsy confirmed the diagnosis of a sporadic desmoid tumor. The patient underwent successful surgical excision of the tumor. Postoperatively, the chiropractor initiated a comprehensive 12-week rehabilitation program that significantly improved the patient's range of motion and muscular strength and alleviated pain. The remarkable aspect of this case was the location of the tumor in the right rhomboid muscle, a less common site for desmoid tumors. This case underscores the crucial role of chiropractors as primary healthcare providers in the early detection of oncological cases and management of post-surgical rehabilitation.
