Few benign and malignant tumors of thyroid lesion share many histological features, including papillary and trabecular pattern, hyalinized stroma, calcification, nuclear grooving, and nuclear inclusion. The lesions those have these common features are hyalinizing trabecular tumor, papillary thyroid carcinoma, medullary carcinoma, paraganglioma, trabecular follicular adenoma (TFA), and poorly differentiated tumor (PDT). These tumors are derived from thyroid follicular cell except PDT and paraganglioma. Hyalinized trabecular tumor and TFA are rare tumors. Due to these common features, they create a diagnostic pitfall for a false-positive or false-negative diagnosis. Therefore, histopathological and immunohistochemical studies are needed to make a definite diagnosis. The present case describes a relatively rare thyroid tumor – hyalinizing trabecular tumor – with its varied morphological features creating diagnostic difficulties and role of immunohistochemistry in formulating definitive diagnosis.
