Question:

Reportability--Thyroid: Is a hyalinizing trabecular neoplasm of the thyroid reportable? See Discussion.

Discussion:

The 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.

Answer:

Hyalinizing trabecular neoplasm is not reportable.

Hyalinizing trabecular neoplasm, or hyalinizing trabecular tumor, is a synonym for hyalinizing trabecular adenoma [8336/0] in the ICD-O-3. The 2004 WHO classification states that "fine needle aspiration biopsy is often interpreted as papillary carcinoma because of the nuclear features in the tumor."
