Lymphangiosarcoma in two cats

Area of Science:

• Veterinary Pathology
• Oncology
• Dermatology

Background:

• Lymphangiosarcoma is a rare vascular tumor.
• Cutaneous tumors in felines can present diagnostic challenges.
• Understanding rare tumor types is crucial for veterinary diagnostics.

Purpose of the Study:

• To report and describe two cases of feline lymphangiosarcoma.
• To characterize the histopathological features of this rare tumor in cats.

Main Methods:

• Histopathological examination of cutaneous tumor biopsies from two cats.
• Microscopic evaluation of tumor cell morphology and tissue infiltration patterns.

Main Results:

• Diagnosis of lymphangiosarcoma in two feline patients.
• Tumor characterized by irregular, anastomosing spaces lined by spindle cells.
• Tumor cells showed a tendency to align along collagen and muscle fibers.

Conclusions:

• Lymphangiosarcoma can occur in cats, presenting as a cutaneous tumor.
• The characteristic histopathological features aid in diagnosis.
• Further studies are needed due to the limited number of reported cases to understand biological behavior and breed incidence.
