Abstract: To the Editor,An 82-year-old female was admitted due to a cervical mass accompanied by a 7-day history of discomfort during swallowing.Physical examination revealed a hard, prominent, and well-defined left anterior cervical mass.High-frequency ultrasound (US) found a left thyroid lobe mass with irregular, ill-defined margins, hypoechoic and heterogeneous aspect (sheet-like hypoechoic area and floating light spot within) (fig 1a).Color Doppler US displayed moderate blood flow signals (fig 1b).Computed tomography (CT) demonstrated a low-density mass in the left thyroid lobe with heterogeneous density, irregular contour, and indistinct margin, measuring approximately 45x39 mm.Notably, patchy calcification was observed, with CT value ranging from 46 to 69 Hu (fig 1c).Finally, the patient underwent surgical resection, and postoperative pathological examination confirmed the diagnosis of intrathyroidal thymic carcinoma (fig 1d).Immunohistochemical staining was positive for CK, CK19, CK5/6, and P63, while it was negative for TP0, TTF-1, Tg, Galectin-3, CD56, CgA, Syn, and EMA.In situ hybridization for EBER was also non-reactive.Notably, a high expression of Ki-67 was detected.Unfortunately,
