Patient:
Female, 52 FINAL DIAGNOSIS: Myxoma Symptoms: -
Medication:
- Clinical Procedure: - Specialty: Oncology.
Objective:
Challenging differential diagnosis.
Background:
Intramuscular myxoma is a benign intramuscular neoplasm. However, sometimes it is difficult to distinguish it from soft-tissue sarcomas that underwent myxomatous degeneration. To the best of our knowledge, only 2 cases of intramuscular myxoma in the soleus muscle have been previously reported.
Case report:
We present the case of a 52-year-old Caucasian woman who was referred to our tertiary anticancer hospital for magnetic resonance imaging (MRI) diagnosis for suspicion of mesenchymal tumor. Percutaneous core biopsy revealed an intramuscular myxoma (IM). Despite the benign nature of the lesion, the patient desired that the tumor be removed. She underwent wide local excision. The final histopathologic diagnosis was IM. She is doing well 3 years after the operation.
Conclusions:
Percutaneous core biopsy is the procedure of choice for providing preoperative tissue diagnosis. The treatment of choice is wide local excision. IM does not usually recur after surgical removal.
