A 6-year-old spayed female domestic shorthair cat with a 3-week history of inappetence, weight loss, and hiding was examined.
A palpable abdominal fluid wave, dehydration, and a small tear on the left flank were noted during initial examination.
When the cat was gently restrained for blood sampling, the skin on the dorsal neck tore, leaving a 15 cm × 7 cm flap of skin. Clinicopathological abnormalities included nonregenerative anaemia, hypoalbuminaemia, increased globulin concentration, and mildly elevated aspartate aminotransferase and alkaline phosphatase activities.
Abdominal fluid was viscous and had a total protein of 5.3 g dL1 with 316 cells µL1, consistent with a modified transudate.
Cytology of the abdominal fluid revealed 86% nondegenerate neutrophils, 13% macrophages, and 1% small lymphocytes.
Histopathological evaluation and indirect immunohistochemistry confirmed a diagnosis of feline infectious peritonitis, hepatic lipidosis and feline skin fragility syndrome.
Feline skin fragility syndrome has not previously been reported in association with feline infectious peritonitis (FIP). Its inclusion as a clinical sign associated with FIP may facilitate a diagnosis.
