Comment on “Ectopic thymic carcinoma of the parotid gland”

We read with interest the paper by Cheng et al.1 in a previous issue of the International Journal of Oral and Maxillofacial Surgery (December 2022) that presented a case report on ectopic thymic carcinoma of the parotid gland. The authors described a 52-year-old man with a parotid gland tumour designated as ectopic thymic carcinoma. Histologically, the tumour was squamous cell carcinoma with lymphocytic infiltration in the background stroma. Immunohistochemically, the tumour was positive for p40, p63, CD117, and Epstein –Barr virus (EBV) but negative for CD5.
