Giant pelvic-perineal leiomyoma simulating a malignant lesion

Abstract

Introduction: Soft tissue tumors are benign or malignant lesions developing from connective tissue and its varieties. Case Report: A 35-year-old patient referred to us for management of a voluminous pelvic-perineal mass. The clinical and para clinical data were in favor of a malignant lesion. The treatment consisted of a wide excision of the tumor. The post-operative period was complicated by an anal incontinence needing a protective left iliac colostomy. A perinioraphy, sphincter refection, and re–establishment of the digestive continuity were performed later on. The cytological examination of the excised mass revealed a conclusive involute hyanilised leiomyoma. Conclusion: This contrast between the clinical, para clinical and histologic data in our patient confirm the diagnostic challenges of soft tissue tumors, hence the need for special technic to assure diagnostic certitude to avoid mutilating surgical approaches for a benign lesion.
