Right adductor compartment intramuscular myxoma: A rare case report.

INTRODUCTION

Extracardiac intramuscular myxomas are exceedingly rare benign tumors, necessitating well-planned management for optimal outcomes.

CASE PRESENTATION: We report the case of a 63-year-old male with no prior medical history, presenting with a progressively enlarging mass within the adductor compartment of the right thigh. Physical examination revealed a mobile and painless mass measuring 70 mm by 50 mm at the level of the adductor compartment of the right thigh, devoid of signs of inflammation or skin lesions. The patient showed no cachexia, asthenia, or weight loss. Imaging exams confirmed the characteristic features of intramuscular myxoma, leading to the decision for complete surgical excision. Subsequent histological analysis confirmed the diagnosis, and the patient experienced no postoperative complications, showing positive long-term follow-up results.

CLINICAL DISCUSSION: In the presence of an intramuscular mass, thorough questioning and meticulous clinical examination enable us to propose a diagnosis of intramuscular myxoma. MRI is the preferred imaging modality, supporting diagnostic reasoning. However, histopathological analysis remains essential to confirm the mass's nature and rule out potential malignant differential diagnoses. Complete surgical resection is considered the gold standard, ensuring favorable results with a low risk of recurrence.

CONCLUSION

Extracardiac intramuscular myxomas are exceptionally rare; MRI and histopathological analysis combined help rule out potential malignant differential diagnoses. Total surgical excision yielded good results with a low risk of recurrence.
