Adenocarcinoma originating from presumed liver ectopic thyroid in a cat.

Case Summary: Ectopic thyroid tissue is rarely reported in dogs and cats in its prediaphragmatic location and has never been described in the liver. A 15-year-old spayed female domestic shorthair cat was diagnosed by ultrasound with a heterogeneous hypoechoic nodular area in the liver at the periphery of the quadrate lobe. A generic diagnosis of carcinoma was made after ultrasound-guided fine-needle aspiration and cytological examination.

Solar dermatitis in a cynomolgus macaque (Macaca fascicularis).

Chronic exposure to ultraviolet (UV) light can cause cutaneous damage, resulting in specific pathological changes such as actinic keratosis and dermatitis. Despite actinic dermatosis being well documented in both humans and animals, it has rarely been reported in non-human primates (NHPs). Here, we describe a case of chronic UV light exposure in cynomolgus macaque (Macaca fascicularis).

Using colorimetric in situ hybridisation method for FcaPV-2 to estimate postsurgical prognosis in feline Bowenoid in situ carcinoma.

Background: Feline Bowenoid in situ carcinoma (BISC) is frequently associated with Felis catus papillomavirus-2 (FcaPV-2). Although surgical excision of BISC is expected to be curative, recurrent lesions are reported and it is not known whether it is a consequence of incomplete surgery or residual viral load.

Objectives: To combine colorimetric in situ hybridisation (CISH) and quantitative (q)PCR for the detection of viral DNA, and to correlate the clinical outcome of cats with BISC in which FcaPV-2 DNA is detected at surgical margins.
