Occult tonsillar squamous cell carcinoma in 2 dogs presenting for treatment of primary oral squamous cell carcinoma

摘要

Canine non-tonsillar oral squamous cell carcinoma (OSCC) is generally regarded as locally invasive with low rates of metastasis. Two cases of canine non-tonsillar OSCC with occult tonsillar squamous cell carcinoma (TSCC) detected with tonsillar biopsies are reported. Tonsillar biopsies and detection of occult TSCC changed the therapeutic plan and may have contributed to long-term tumor control.
