Reportability/Histology--Heme
& Lymphoid Neoplasms: Is a diagnosis of myeloid stem cell disorder or
myeloid stem cell neoplasm reportable when the differential diagnosis includes
only reportable neoplasms? If so, how should histology be coded? See Discussion.
Solid Tumor Rules/Histology--Fallopian Tube: How is histology coded for a high-grade serous carcinoma with admixed yolk sac tumor of the right fallopian tube? See Discussion.
Reportability/Histology--Soft Tissue: Is superficial CD34 positive fibroblastic tumor reportable and if so what histology code should be used? See Discussion.
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--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?
Reportability/Histology--Lung: Are adenocarcinoma spectrum lesions on lung imaging reportable when no further information is available? See Discussion.
2024 SEER Manual/Primary Site--Retroperitoneum: What is the primary site code for a final diagnosis of endometrioid adenocarcinoma from a biopsy of a right retroperitoneal mass? See Discussion.
SEER Manual/Reportability--Vulva: Is vulvar intraepithelial neoplasia (VIN II) alone reportable? An example is a final diagnosis from a pathology report that states only 'VIN II' with no additional details/wording.
2024 SEER Manual/Reportability--Breast: Is "lobular intraepithelial neoplasia" (LIN) a glandular intraepithelial neoplasia? If so, is lobular neoplasia II (LN II)/LIN II non-reportable, similar to PanIN II - SINQ 20240026? See Discussion.
