Lymphangiosarcoma is a rare tumor of the soft tissues, in particular outside of cases where the etiology is represented by chronic edema following mastectomy for breast cancer (Stewart-Treves syndrome). In the case reported, the patient experienced chronic edema of the lower limbs, with diffuse
A case of a lymphangiosarcoma (LAS) in a chronic postmastectomy lymphedematous arm in a 67 y.o; women is reported. The LAS was found 8 years after a radical left mastectomy for cancer and 7 years after the development of a lymphedema in the left arm. Because of a rapid spread of the disease no
A 4-year-2-month-old female Japanese domestic cat was diagnosed with lymphangiosarcoma through tissue biopsy of an amputated leg. Two months later, the cat was euthanized, and postmortem findings revealed edema, and bruising at the caudal region of the trunk, pulmonary hemorrhage, pulmonary nodules
Lymphangiosarcoma was seen in the subcutis of right chest in a 11-year-old female Poodle. No metastasis was observed clinically. Tumor cells were vimentin positive and formed irregular space or slit without erythrocytes in the tumor tissue. Lymphocytic foci and edema were seen in the stroma. Only a

Diffuse lymphangiosarcoma involving the superficial and deep dermis and subcutaneous tissue was observed on skin biopsies. Lymphangiosarcoma is
A lymphangiosarcoma with metastases was found in a horse that presented with respiratory distress and edema in the ventral thorax and abdomen.

Angiosarcomas are malignant tumors derived from the endothelium of blood vessel (hemangiosarcomas) or lymph vessels (lymphangiosarcomas). Lymph edema of the limbs is considered secondary when extrinsic injuries are observed and primary when these injuries are not present. Stewart-Treves syndrome or
In 1948, Stewart and Treves (158) described a lymphangiosarcoma on the edematous arm for the first time with reference to six cases involving arm edema after breast cancer operation. Since their publication, a further 313 cases have become known. In 1982, with communication of one case we published
Stewart-Treves syndrome (STS) is a rare cutaneous lymphangiosarcoma developing from chronic lymph edema as a consequence of radical mastectomy or surgical invasion of the groin for the treatment of cervical or penile cancer. Previous reports suggested possible mechanisms in the development of
This review presents the diagnostic features, the pathophysiology and the available therapies for lymphedema. This disease is often able to be diagnosed by its characteristic clinical presentation, yet, in some cases, ancillary tests might be necessary to establish the diagnosis, particularly in the
