a Tumor cells with clear cytoplasm and rhabdomyoid tumor cells with eosinophilic nuclei intermingled with diffuse patchy arrangement and necrosis in the center [hematoxylin and eosin (HE) 100×]. b Junction between the typical parathyroid carcinoma cell region and the differentiated cell region of rhabdoid sarcoma (HE, 50×). c Rhabdoid tumor cells, eosinophilic cytoplasm, nuclear deviation, and obvious nucleolus (HE, 400×). d obvious characteristics of parathyroid glands: small cubic clear cells, abundant slender fibrovascular compartments (inside the red oval).(HE, 200×)
