Reportability/Histology--Hematopoietic, NOS: What histology code is used for a patient diagnosed with "myelodysplasia" prior to 2001, if a bone marrow biopsy in 2002 is consistent with myelodysplastic syndrome with refractory anemia with bilineage dysplasia with excess blasts and the final impression is "myelodysplastic syndrome slowly evolving toward acute leukemia?"
Reportability/Histology--Head and Neck: Is mammary analogue secretory carcinoma (MASC) of the left submandibular gland reportable and how is it coded? See Discussion.
Reportability/Histology--Head and Neck: Is a right cerebellopontine (CP) angle endolymphatic sac papillary tumor (ELST) reportable? If so, what is the histology code?
Reportability/Histology--Head & Neck: Is a 2023 mandibular biopsy showing “severe squamous dysplasia with microscopic focus suspicious for superficial invasion” reportable? See Discussion.
Reportability/Histology--Head & Neck: Is carcinoma cuniculatum of the hard palate diagnosed in 2017 reportable? Was this rare variant of squamous cell carcinoma (SCC) missed in Casefinding? If reportable, what is the histology code?
Reportability/Histology--Gallbladder: Is Intracholecystic papillary neoplasm (ICPN) with low-grade intraepithelial neoplasia reportable? The primary site is gallbladder.
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.
