In the present study, a case of gingival squamous cell carcinoma is described in a 9-year old sheep dog with a swelling of the left mandible. Plain radiographs of the head revealed a soft tissue mass behind the ventral border of the left mandible. At necropsy, the tumor presented as reddish-brown...

Objective: Retrospective analysis of dogs with gingival squamous cell carcinoma (SCC) surgically treated using jaw resection. Material and methods: A total of 40 dogs were enrolled in the study. Dogs with incomplete tumour resection or metastases were subjected to adjuvant chemotherapy using...

Oral cavity tumours and tumour-like lesions are common in dogs and cats, and their diagnosis and classification requires histopathological examination. The aim of this study was to analyse retrospectively oral cavity lesions in dogs and cats in order to evaluate the distribution of inflammatory,...

This article describes clinical, gross and histological findings and distant metastases from a gingival squamous cell carcinoma (SCC) that mimicked chronic gingivitis and periodontitis in its early presentation in the right maxillary area of a 6-year-old male terrier dog in Turkey [date not given]. ...

We describe clinical and pathological findings in a 9-year-old sheep dog with gingival squamous cell carcinoma. The dog was presented with a swelling of the left mandible. Plain radiographs of the head revealed a soft tissue mass behind the ventral border of the left mandible. At necropsy, the...

Grade and labeling indices for immunohistochemical tumor proliferation markers Ki-67 and proliferating cell nuclear antigen (PCNA) were evaluated in 36 cases of canine oral squamous cell carcinoma (OSCC) based upon intraoral location. Grade was significantly associated with location (P=.035). Grade ...

Perturbation of cell adhesion can be essential for tumor cell invasion and metastasis, but the current knowledge on the gene expression of molecules that mediate cell adhesion in canine oral tumors is limited. The present study aimed to investigate changes in the gene expression of cell adhesion...

Oral squamous cell carcinoma (OSCC) and canine acanthomatous ameloblastoma (CAA) represent two epithelium-derived neoplasms that affect the oral cavity of dogs. The expression of cytokeratins (CKs) and calretinin has been previously established in the canine tooth bud and odontogenic tumours. The...

An 8-year-old, spayed, female Labrador Retriever mixed-breed dog was presented to the Cornell University Hospital for Animals with an invasive oral mass involving the upper left fourth premolar and first molar teeth. Initial biopsy results suggested a poorly differentiated squamous cell carcinoma,...

A 7-year-old, male cocker spaniel was presented with a gingival proliferative lesion in the rostral maxilla and enlargement of the regional lymph node. Morphological and immunohistochemical analysis revealed a collision tumour composed of two malignant populations, epithelial and melanocytic, with...
