title: Hyalinizing trabecular adenoma.
abstract: A case is presented of hyalinizing trabecular adenoma in a 54-year-old Japanese female. The patient underwent a hemithyroidectomy for the diagnosis of thyroid carcinoma. An intraoperative frozen section diagnosis was medullary carcinoma. Hematoxylin and eosin stained permanent sections from the surgical specimen, a well encapsulated 3.0 x 2.0 x 1 cm nodule, also led us to suspect medullary carcinoma, but immunohistochemical staining for thyrocalcitonin, CEA, and thyroglobulin showed that it was a hyalinizing trabecular adenoma.
