Some of the adenocarcinoma variants (SRC) tend to present with prominent bladder wall thickening (âlinitis plasticaâ like) without apparent growth due to diffuse infiltration of the bladder wall by tumor cells. Results: Average follow-up time was 77 months. Adenocarcinoma is the non-smoker tumour - SCLC and squamous are more strongly associated with smoking. Variable histologic features based on adenocarcinoma in situ type Most adenocarcinoma in situ types are associated with high risk human papillomavirus (HPV) Negative p16 immunohistochemical staining may indicate a non HPV associated adenocarcinoma in situ type Colo-Rectal Adenocarcinoma Focused Colo-Rectal Adenocarcinoma with stained slides of pathology.
