Stewart-Treves syndrome. A report of two cases with a review of Japanese literature

Stewart-Treves Syndrome Involving Chronic Lymphedema after Mastectomy of Breast Cancer

Steward-Treves syndrome is a cutaneous angiosarcoma that usually appears after long evolution of a lymphoedema after mastectomy for mammary neoplasia associated with an axillary dissection. This is a rare disease develop most of the time in upper arm and often confounded with cutaneous metastasis. Only the biopsy and immunohistochemical study confirm the diagnosis. The treatment is surgical and consists of large cutaneous excision, an amputation of the limb or even its disarticulation and will be followed by chemotherapy. Despite the treatment, the prognosis remains severe with poor survival. We report the case of a patient who had a Steward-Treves syndrome 20 years after lymphoedema following a left mastectomy with axillary dissection.

Stewart Treves Syndrome in a Woman with Mastectomy

Stewart Treves Syndrome is an angiosarcoma generally seen long time after radical mastectomy in breast carcinoma patients in chronic lymphoedema area. It's an angiosarcoma developed on a long standing lymphoedema, following a radical mastectomy. An 86-year-old woman was referred to our Dermatology outpatient clinic which developed a giant erythematous, oedematous, purplish lobulated plaque on her right forearm anteromedially with a few satellite erythematous papulonodules on her arm. The pathology revealed spindle-shaped tumour cells invading dermis with vascular differentiation into the subcutaneus tissue which are compatible with a diagnosis of angiosarcoma.

Stewart Treves Syndrome: A Case Report

Angiosarcomas are malignant tumors, which originate from the vessel endothelium and resemble the vessel structure. Stewart-Treves syndrome is an angiosarcoma which in general, develops in female patients after mastectomy and axillary lymph node dissection and is associated with chronic lymphedema. The prognosis of this rare complication is very poor. We present the case of a 52-year-old female who had undergone mastectomy due to breast cancer and 13 years later required shoulder disarticulation due to Stewart-Treves syndrome.

Epithelioid Angiosarcoma of the Small Intestine After Occupational Exposure to Radiation and Polyvinyl Chloride: A case Report and Review of Literature

Angiosarcomas represent 1–2% of soft tissue sarcomas and most frequently occur in the subcutis. They may affect internal organs, such as the heart, liver, and spleen, and only rarely do they emerge in the gastrointestinal tract. The association between angiosarcomas and certain toxic chemical substances or previous external-beam radiation therapy is well documented.

Lymphangiosarcoma (Stewart-Treves syndrome) in postmastectomy patients

Stewart-Treves syndrome (STS) is a rare but aggressive upper extremity lymphangiosarcoma in postmastectomy patients. Unfamiliarity with this disease and the innocuous appearance of the tumor often lead to delayed diagnosis. A comprehensive search of the databases at a single tertiary-care academic institution revealed only 3 cases of STS in the last 63 years. The latency time between breast cancer treatment and diagnosis of STS was 11 to 21 years. Survival after diagnosis of STS ranged from 8 to 15 months. One patient underwent radical surgery. The extensive lymphangiosarcoma in the other 2 patients precluded surgical resection and they underwent chemotherapy. All patients had adjuvant radiation therapy at the time of the original breast cancer resection. This report includes a discussion of the epidemiology, etiology, presentation, treatment, and prognosis of STS.

Lymphangiosarcoma in chronic lymphoedema. Stewart-Treves syndrome

A case of post-mastectomy lymphangiosarcoma is reported. Lymphangiosarcoma is an extremely rare but highly lethal complication of chronic lymphoedema. Our patient was treated by amputation and died 6 months later. Treatment of post-mastectomy lymphangiosarcoma is still unsatisfactory. Early recognition and radical ablative surgery seem to provide best chance for survival.
