~소화기에서 Colonoscopic Mucosal and Submucosal Resection 시술하신 분인데, 조직검사결과를 보니 M코드를 어떻게 줘야할지 모르겠어서 질문드립니다.【판독결과】Specimen: 1 group   A piece of grayish-tan polypoid mass, measuring 1.1 x 0.7 x 0.4 cm in size    Entirely blocked in A. DIAGNOSIS :Cecum, colonoscopic mucosal resection:  A well-circumscribed submucosal lesion    composed of cystically dilated atypical oncocytic glands in a rich lymphoid stroma,      favor GALT/dome-type carcinoma, well-differentiated, 0.2 cm in greatest dimension,        with 1) overlying high-grade dysplastic adenomatous component,                  1.1 x 0.7 cm in size             2) confinement to submucosa (1.5 mm in thickness)              3) lymphovascular invasion: not identified             4) perineural invasion: not identified             5) indeterminate resection margin              6) pT1 by AJCC 8th edition        (See note) note) The overall microscopic findings favor a GALT/dome-type carcinoma. It is thought that the tumors represent early low-grade lesions limited to the submucosa (pT1). Recurrences or metastases to lymph nodes or distant sites have not been reported for any patients with this tumor, and, thus it seems resonable to conclude that adequate local excision is sufficient treatment (Chetty R et al. World J Gastrointest Oncol 2019 15;11:59-70).*Immunohistochemical staining result   p53: positive, diffuse현재 암과 관련한 다른 영상학적 검사는 시행하지 않았습니다.BX 관련해서 자료를 찾아보니 굉장히 드문 케이스 같습니다.. 교수님께서 악성은 맞다고 하셨는데, 적합한 M코드가 무엇인지 알려주시면 감사하겠습니다~
병리자문 결과 해당 진단명은 매운 드문 variant of adenocarcinoma 의 증례로서 부여 가능한 세부 코드가 없으므로 M8140/3(Adenocarcinoma, NOS) 로 코딩해주시기바랍니다.
