Successful clinical remission of feline cutaneous lymphangiosarcoma with surgical resection

Abstract

Abstract This case report highlights the successful management of cutaneous lymphangiosarcoma in an 11‐year‐old, female spayed, domestic longhair cat with surgical resection alone. A 2.0 cm × 1.5 cm, compressible, erythematous, alopecic dermal plaque located on the caudoventral abdomen with associated subcutaneous thickening was cytologically examined, revealing abundant small lymphocytes and a low number of large mesenchymal cells. A definitive diagnosis could not be made based on cytology; therefore, biopsy with histopathology was performed and was consistent with cutaneous lymphangiosarcoma. Complete clinical remission was achieved with curative intent surgical excision. This rare malignant neoplasm of the lymphatic endothelium carries a poor prognosis with rapid progression of disease even after surgical resection. Early diagnosis and aggressive surgical intervention likely resulted in the good outcome in this case.
