Putative paraneoplastic alopecia in a cat with apocrine adenocarcinoma.

Feline paraneoplastic alopecia is associated with intraabdominal neoplasms. A 13-year-old female cat was presented with a history of a cutaneous mass on the head, followed by ventrally distributed alopecia with shiny skin. Necropsy revealed an apocrine adenocarcinoma and telogenisation/miniaturisation of the hair follicles, respectively. These findings are consistent with paraneoplastic alopecia.
