title: Papillary thyroid microcarcinoma in Graves' disease presenting as a cystic neck mass.
abstract: The presentation of papillary thyroid microcarcinoma (PTMC) as a solitary cystic neck mass is uncommon. Additionally, its association with Graves' disease is very rare. We report a case of occult PTMC, who presented with a cystic neck mass in the background of Graves' disease without any goiter. Imaging like ultrasound of neck, single photon emission computed tomography-CT (SPECT-CT), and technetium scan failed to detect any lesion in the thyroid, which was picked up only by the contrast-enhanced computed tomography (CECT) of neck. The patient underwent total thyroidectomy with right modified lymph node dissection. Our case highlights the presentation of metastatic PTMC as a differential diagnosis of a cystic neck mass even in a patient with Graves' disease without any thyroid enlargement.
