Question
Reportability--Thyroid: Is a hyalinizing trabecular neoplasm of the thyroid reportable? Pathology comment states: Hyalinizing trabecular neoplasm is considered by some to represent a variant of papillary thyroid carcinoma because of the similar nuclear cytology, immunoprofile and RET-oncogene rearrangements.

Discussion


Answer
Hyalinizing trabecular neoplasm is not reportable. Hyalinizing trabecular neoplasm, or hyalinizing trabecular tumor, is a synonym for hyalinizing trabecular adenoma in ICD-O-3, which is coded 8336/0. The 2004 WHO classification states that "fine needle aspiration biopsy is often interpreted as papillary carcinoma because of the nuclear features in the tumor" (page 104).
