Plain-English summary

A 9-year-old male domestic shorthair cat was brought in for hair loss, increased appetite, and weight loss that had been worsening over six weeks. The vet diagnosed him with a skin condition called lymphocytic mural folliculitis and treated him with prednisolone and ciclosporin, which helped improve his hair loss but didn't completely resolve it. Sixteen months later, the cat returned with intermittent vomiting and continued weight loss, and further tests revealed a mass in his pancreas, diagnosed as pancreatic cancer. Unfortunately, while the skin condition showed some improvement, it was linked to a more serious underlying issue.

Abstract

A 9-year-old castrated domestic shorthair cat was presented with a 6 week history of progressive non-pruritic alopecia, polyphagia and weight loss. A diagnosis of lymphocytic mural folliculitis was made and the cat was treated with a combination of prednisolone and ciclosporin; this produced an improvement in the alopecia but no resolution. Sixteen months after the initial assessment and diagnosis, the cat was re-evaluated for intermittent vomiting and weight loss with normal appetite. On examination the dermatopathy was still evident and a mass involving the duodenum and pancreas was present, which was diagnosed as a pancreatic carcinoma. From this case it would appear that lymphocytic mural folliculitis might be an early dermatological manifestation of pancreatic neoplasia.
