Abstract

Two cases of papillary thyroid carcinoma presenting as a cystic lateral neck mass are reported. This tumour characteristically presents in patients under 40-years-old and in the presence of an occult primary tumour may mimic a branchial cyst. In such cases simple aspiration of the cyst will produce a chocolate-brown serous fluid which excludes the diagnosis of a branchial cyst and is characteristic of papillary thyroid carcinoma. Cytological examination of the fluid has a high degree of sensitivity and specificity in the diagnosis of thyroid malignancy and should avoid delay in diagnosis and unneccessary surgical exploration prior to definitive treatment.
