Carcinoma showing thymus like differentiation (CASTLE) is a rare tumor involving soft tissues of the neck and the thyroid gland. It arises from ectopic thymus or remnants of branchial pouches in the neck. It may present as an asymptomatic neck or thyroid mass, which may or may not be invasive. Most cases follow an indolent course and have good prognosis. We report a case of 34-year-old female who presented with hoarseness of voice and mass in the neck. Surgical excision was done. Histopathology and immunohistochemistry (CD5 positivity) revealed carcinoma showing thymus like differentiation (CASTLE). No recurrence was noted after one year of follow-up.
