Giant epidermal inclusion cyst of the thyroid: a rare occurrence

ABSTRACT

Epidermal inclusion cyst (EIC) of the thyroid is extremely rare in the clinical practice. A handful of cases have been documented in the past in the world literature. A giant EIC of the thyroid is hitherto unreported. This lesion may arise from the squamous metaplasia of the thyroid follicular cells. Though non-neoplastic, giant forms can cause compression of the vital structures of the neck. In the present case, we have described a giant epidermal inclusion cyst successfully managed with surgical management.
