In 1995, Apel et al described a subtype of papillary carcinoma of the thyroid that is made up primarily or entirely of Hurthle cells within a lymphocytic stroma; this entity displays a striking resemblance to Warthin's tumor (papillary cystadenoma lymphomatosum of the salivary gland). 4-6) Acinic cell carcinomas of the parotid gland occur bilaterally in 3% of cases, a rate of bilaterality that is second only to that of Warthin's tumor. There were 8 cases of pleomorphic salivary adenoma and 1 case of Warthin's tumor. |
