Clinico-Histopathological Studies in Canine Transmissible Venereal Tumour

Transmissible Venereal Tumour in Dogs

Pathogenesis and evolution o f Canine Transmissible Venereal Tumour

Canine Transmissible Venereal Tumour (CTVT) is a neoplastic disease occurring naturally in dogs. CTVT is usually sexually transmitted, but transmission may occur by licking, biting, or scratching tumour-affected areas. Cytogenetic studies directed to verify the cell transmissibility of the CTVT showed that the tumour cells are characterized by a rearranged karyotype, which is similar in tumours...

Cytomorphological Study of Canine Transmissible Venereal Tumor

Introduction Canine transmissible venereal tumor (CTVT) is classified as a round cell tumor. It always revealed in round to ovoid shaped cell, moderate amount of vacuolated cytoplasm with a large round to ovoid nucleus and prominent nucleoli (2). However, Amaral et al. (2007) reported that CTVT cytomorphology was classified into three types according to the majority of cell type population: pla...

Cytologic subtypes of canine transmissible venereal tumor.

Canine transmissible venereal tumor (CTVT) is a transplantable neoplasm that has stimulated much scientific effort to determine its cell of origin, mode of transmission, and reasons for spontaneous regression as well as similarities with other types of animal and human cancers. In 1994, on the basis of the hypothesis that different cytomorphologic types of CTVT may have different biologic behav...

Identification of Risk Factors for Canine Transmissible Venereal Tumour (CTVT) in Owned Dogs in Pakistan

A matched case-control study was conducted to investigate the risk factors for canine transmissible venereal tumour (CTVT) in owned dogs of Lahore District, Pakistan. Ninety six laboratory-confirmed CTVT positive dogs were matched on the date of clinic visited with 96 control dogs. The univariate analysis was employed to assess the relationship between different population characteristics and t...
