This is my own 9 year old dog who has developed a firm, non mobile mass on her right neck, just cranial to the larynx.  It seems to be growing fairly rapidly.  On FNA cytology there was quite a bit of inflammation and  necrosis, but also many ” atypical”=”” epithelial=”” cells,=”” some=”” clustered. =”” the=”” pathologist=”” said=”” she=”” could=”” not=”” identify=”” their=”” origin,=”” but=”” they=”” were=”” concerning=”” for=”” a=”” neoplasm. =”” i=”” have=”” culture=”” pending,=”” wondered=”” if=”” anyone=”” tell=”” me=”” what=”” this=”” structure=”” might=”” be. =”” it=”” appears<a=”” rel=”gallery-all”> lateral to the carotid, so not thyroid, but is it possibly ectopic thyroid tissue?  I thought it was a lymph node, but few lymphocytes were seen on the cytology.  Thanks for any help.
