Plain-English summary
A 4-year-old female Japanese domestic cat was diagnosed with lymphangiosarcoma, a type of cancer affecting the lymphatic system, after a tissue biopsy of an amputated leg. Unfortunately, two months later, the cat was euthanized due to the progression of the disease, which had spread throughout her body, causing severe swelling and bruising, as well as lung issues. The findings showed that the cancer had metastasized to various organs, including the lungs and lymph nodes. Despite the diagnosis, treatment options were limited, and the cat's condition deteriorated rapidly.

Abstract
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 and mediastinal lymphadenopathy. Microscopically, neoplastic tissues were observed in the dermis and subcutis of the trunk, lung, mediastinal lymph nodes, diaphragm, omentum and mesentery. The tumor cells were spindle to polygonal-shaped with nuclear pleomorphism aligning along pre-existing collagen bundles and forming irregular vascular channels in which the erythrocytes were rarely observed. These cells were immunopositive for vimentin, von Willebrand factor and CD31. Based on the histopathological and immunohistochemical features, the neoplasia was diagnosed as lymphangiosarcoma with systemic metastases.
