Reportability--Vulva: Is well differentiated vulvar intraepithelial neoplasm (dVIN) reportable? See Discussion.

Reportability/Histology--Penis: Is a diagnosis of undifferentiated penile intraepithelial neoplasia (PeIN) reportable for cases diagnosed in any year? See Discussion.

MP/H/Multiple primaries--Stomach: How should I report this case? I reviwed both the MP/H and the Heme Rules and could not determine whether or not this case is multiple primaries in a single site but two histologies and therefore needing two separate abstracts.

Path Diagnosis: Gastric Mass Biopsy: 1) Signet Ring Cell Carcinoma. 2) Extranodal Marginal Zone Lymphoma of Mucosa-Associated Lymphoid Tissue (MALT Lymphoma). 3) Mild Intestinal Metaplasia and Marked Fundic Gland Atrophy, Negative for H Pylori. Comments: Biopsy shows presence of both signet ring carcinoma and MALT Lymphoma.

Reportability/Histology--Heme & Lymphoid Neoplasms:  How should this unusual 2023 pathology-only case be reported and coded for leukemia cutis? See Discussion.

Reportability/Histology--Thymus: Is a 2021 diagnosis of a type A microscopic thymoma reportable? See Discussion.

Reportability/Histology--Heme & Lymphoid Neoplasms:  Should a non-Langerhans cell histiocytosis involving the hypothalamus and pituitary gland be accessioned as a reportable, behavior /1, CNS neoplasm? See Discussion.

Reportability/Histology--Thymus: Is a thymoma a malignancy if described as having separate tumor nodules within peri-thymic adipose tissue? See Discussion.

Reportability--Skin: Is this case not reportable if the intranasal polyp is covered with cutaneous epithelium (essentially skin) or, is it reportable as a primary intranasal basal cell carcinoma? I have found one article regarding primary intranasal basal cells, which are described as being "very rare". But, I am not sure whether, in those cases, cutaneous epithelium was found.

FINAL DIAGNOSIS: (A) Nasal cavity, polyp, excision: Sinonasal inflammatory polyp with overlying cutaneous epithelium showing foci of superficial (noninvasive) basal cell carcinoma

Reportability/Histology: Is this reporatable? If so, what is the correct histology?

2012 duodenal nodule biopsy, pathology positive for well differentiated neuroendocrine neoplasm.

Reportability/Histology--Eye: Is conjunctival intraepithelial neoplasia, moderate to severe, reportable and if so, what are the histology and behavior codes? See Discussion.
