“…Other studies of ectopic thymic tissue in the neck of children have found variable incidence, ranging from 0.99% of cases to 33% of cases . The lowest prevalence of 0.99% cases was reported in an ultrasound screening study of over 37 000 children and found that the incidence of ectopic intrathyroidal thymic tissue was inversely correlated with age .…”

Cytomorphology and sonographic features of ectopic thymic tissue diagnosed in paediatric FNA biopsies

et al. 2018

Ectopic thymic tissue is rarely present as a neck mass or thyroid nodule on FNA biopsy. The ultrasound imaging findings reveal a well-defined fusiform lesion with punctate bright echoes that could be misinterpreted as papillary thyroid carcinoma. The aspirates show a small lymphoid population, immunophenotypically compatible with thymic T-cells, in addition to scattered epithelial cells. Therefore, knowledge of the typical ultrasonographic and cytopathological features can help make a definitive diagnosis and avoid more invasive procedures in paediatric patients.

“…ECT has been commonly reported in the pediatric literature, mostly at autopsy, and uncommonly presents as a neck mass [1,5,6]. Most of the time, the finding may be incidental, correlating with a period of maximum growth of the thymus, but only rarely in adults, as they involute.…”

Ectopic cervical thymus is a rare congenital anomaly, which results because of the failure of complete descent of the thymus. They are incidental findings in the young and may disappear during the early years of life; however, they have rarely been described in adults. Some of them may undergo hyperplasia or neoplastic transformation and become visible or cause symptoms. We report two rare cases of incidentally detected cervical thymic tissue in adults. In one case, the thymic tissue was seen adjacent to a parathyroid adenoma of the left inferior parathyroid gland. In the other, it was seen adjacent to the left inferior parathyroid gland in a case of papillary thyroid carcinoma. In both these cases, the ectopic thymic tissue was diagnosed as a result of pathological examination, not clinically by macroscopic appearance during operation or radiological evaluation. The finding needs to be noted as these ectopic foci can occasionally give rise to hyperplasia and neoplasms of the thymus.

“…The most common presentation is as a neck mass, frequently near the inferior pole of the thyroid gland. 6 Cervical thymic cysts can be challenging to diagnose and are difficult to distinguish from lymphatic malformations and branchial cleft cysts. 5 Histopathological analysis is necessary for definitive diagnosis.…”

Ectopic cervical thymus: A clinicopathological study of consecutive, unselected infant autopsies

Abstract: This study revealed that ECT is an essentially benign anomaly that occurs frequently during the development of the thymus, and may disappear over the first few years of life. These results suggest a conservative approach to the management of ECTs would be appropriate.
