摘要

Background: Primary cutaneous leiomyosarcoma (LCP) is a malignant tumor that can originate from smooth muscles(hair arrestor or vessels of hypodermic tissue). Recidivism rates vary by type. We report two particular cases by thevolume of their recidivism and to underline the difficulties of management. Observations: ZA, 41 years old, was receivedafter surgery for a voluminous, painless, firm, mobile and ovoid mass of 7 cm on the knee. The tumor occupied mainlythe superficial and reticular dermis. It did not have immunohistochemistry but a re-reading of the blade concluded atdiagnosis. The assessment of the extension did not objectify anything and the patient lost sight of. KM, 36 years wasreceived 3 months after surgery, under the same conditions for a voluminous ulcerous burgeoning tumor, oblong 9 cmlong axis of the shoulder curve. The histopathological lesions were extended to the subcutaneous tissue. The extensionreport showed lymphadenopathy, hepatic and pulmonary metastases. The patient underwent clean surgery associatedwith adjuvant chemotherapy. Conclusion: These relapses have no reliable information on the prognostic factors of theirinitial management. Nevertheless, the major factor of recurrence remains the tumor clearance, probably not obtainedduring the first excision. Close multidisciplinary collaboration is essential for the appropriate management of LCP.
