MALIGNANT MESOTHELIOMA WITH METASTASES AND MAST-CELL LEUKEMIA IN A CAT

Abdominal malignant mesothelioma was found in a 17-year-old, spayed fe male Japanese domestic cat with mast cell leukaemia. The mesothelioma was mainly located at the periphery of the pancreas, spleen and stomac h, and showed metastases to the lung, an anterior mediastinal lymph no de and lymph ducts in the tracheal mucosa. Micro-circulatory defects c aused by the mast cell leukaemia may have been partly responsible for the distant metastases.
