“…In particular, two dogs were excluded from the analysis because of the presence of two concomitant neoplastic processes in the same mass. Similar observations in the oral cavity are rare, but have been previously described in both humans (Dallera et al, 1982;Ryu et al, 2000;Lim et al, 2008) and dogs (Watrach et al, 1970;Pérez-Martínez et al, 2000;Sitzman, 2000). These cases highlight the primary importance of histopathology in achieving a correct diagnosis for some oral cavity lesions.…”

Neoplastic or non-neoplastic masses are common findings in the oral cavity of cats and dogs. The aim of this prospective study was to compare the results of cytological examinations of lesions of the oral cavity following fine-needle aspiration (FNA), fine-needle insertion (FNI), and impression smear (IS) with histopathological results being considered as the diagnostic gold standard. In total, 85 dogs and 29 cats were included in the study. Cases were included when histology and cytology (FNA, FNI, and/or IS) were available from the same lesion; -agreement and accuracy between cytological and histopathological results were calculated. Eighteen cytological specimens were excluded, with a retrieval rate of 84.2%.

Cervical neck dissection is a frequent technique during treatment for oral squamous cell carcinoma (SCC). Occasionally, specimens harvested as cervical lymph nodes reveal thyroid tissue and need differentiation with metastatic thyroid cancer and ectopic thyroid tissue. Here, we report a case of an ectopic thyroid tissue with lymphocytic thyroiditis mimicking thyroid cancer metastasis at the cervical lymph node.

“…Except for cancers of hematopoietic cell origin that often involve multiple lymph nodes systemically, a very limited number of cases of collision metastases in the lymph nodes have been described in the literature. [1][2][3][4][5][6][7][8] Here, we report an extremely rare case of lymph node collision metastasis from rectal and prostatic cancers.…”
