Reportability/Histology--Gallbladder: Is intracholecystic papillary-tubular neoplasm (ICPN) with extensive high grade dysplasia of the gallbladder reportable?
Reportability/Histology--Fallopian Tube: Is a diagnosis of serous tubal intraepithelial neoplasm (neoplasia) (STIN) equivalent to serous tubal intraepithelial carcinoma (STIC)? Does the designation of high or low grade have any effect on potential reportability? See Discussion.
Reportability/Histology--Eye: Is “squamous mucosa with high grade dysplasia” equivalent to a diagnosis of “high grade squamous dysplasia?” See Discussion.
Reportability/Histology--Eye: Is conjunctival intraepithelial neoplasia, moderate to severe, reportable and if so, what are the histology and behavior codes? See Discussion.
Reportability/Histology--Endometrium: Is endometrial hyperplasia with atypia equivalent to atypical hyperplasia of the endometrium (8380/2) and thus reportable?
Reportability/Histology--Endometrium: Are the following terms and diagnoses synonymous with endometrioid intraepithelial neoplasia (EIN) and therefore reportable?
1. Atypical glandular epithelium
2. Isthmic-type mucosa with focal severe atypia
3. Simple hyperplasia without atypia
4. EIN/complex atypical hyperplasia (EIN/CAH) or focal EIN/CAH (on biopsy but the resection pathology or operative note states no EIN/CAH/atypical hyperplasia)
Reportability/Histology--Digestive Sites: Is a diagnosis of “tubulovillous adenoma with high grade dysplasia” in the duodenum equivalent to a diagnosis of “tubulovillous adenoma, high grade” and, therefore, non-reportable, or is this a reportable non-colorectal high grade dysplasia? See Discussion.
Reportability/Histology--Conjunctiva: Is low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL) with focal high-grade features of the conjunctiva (C690) reportable? If reportable, what histology should be assigned?
