MP/H Rules/Histology--Pleura: How is histology coded when the pathology report final diagnosis is "malignant neoplasm, compatible with malignant mesothelioma" if the COMMENT section of the pathology report indicates the tumor has a mixed epithelial and sarcomatoid pattern? See Discussion.
Systemic/Surgery Sequence--Bladder: How is the systemic treatment/surgery sequence field coded for a 2013 case if the patient has a TURBT followed by multi-agent chemotherapy, and then a cystoprostatectomy followed by post-operative multi-agent chemotherapy?
Reportability: Is a clinically diagnosed Stage III malignant thymoma reportable when the post-neoadjuvant resection showed spindle cell thymoma? See Discussion.
Reportability/Behavior: Is HGSIL (high grade squamous intraepithelial lesion) of the vulva or vagina reportable and is it a synonym for histology code 8077/2 [squamous intraepithelial neoplasia, grade III]?
Reportability--Heme & Lymphoid Neoplasms: Is a peripheral blood finding consistent with involvement by monoclonal, lambda-restricted mature B cell population with co-expression of CD5 and CD23 reportable if, immunophenotypically, the case is consistent with a chronic lymphocytic leukemia/small lymphocytic lymphoma? See Discussion.
