Superficial leiomyosarcomas are rare soft tissue sarcomas resulting from the dermis or subcutaneous tissue. They show a preference for proximal ends and tend to be slow-growing. They clearly show different histological and prognostic characteristics depending on whether they are cutaneous or subcutaneous. Case Report: We reported the case of subcutaneous leiomyosarcoma resulting in the medial subinguinal region of the right thigh in a 58-year-old female. Leiomyosarcoma is an entity whose clinical presentation may appear non-specific, making diagnosis difficult. We discussed the case with a brief review of the literature and the difficulties of a first approach clinical diagnosis. Conclusion: In conclusion, a long period of patient follow-up is recommended to capture a subsequent malignant progression of the disease.
