During a routine lab dissection, lesions were found to be scattered along the mesentery of the colon and small intestines, as well as the abdominal peritoneum. Due to its presentation and histological analysis, a diagnosis of adenocarcinoma was made. Adenocarcinomas are mucus-secreting cells that are found within and near the glands of organ (Nakhaie, Mohsen et al., 2020). One of the most common clinical manifestations of adenocarcinomas is within the colorectal region due to the numerous mucous secreting cells found within these sites. Literature reviews have indicated that different metastasis patterns that can differentiate between adenocarcinomas of various histological subtypes.

OBJECTIVES: The primary objective of this study is to analyze the progress of metastasis of an adult male cadaver found in a routine academic dissection.

METHODS: This study consists of a case study of an adult male cadaver and literature review regarding metastasis of colorectal adenocarcinomas. Histological slides were taken from the small intestine mesentery, ileocecal junction, liver, lungs, epidermis of the left lateral anterior neck, abdominal aorta and abdominal peritoneum.

RESULTS: Current histological slides indicate the presence of adenocarcinoma within the abdominal peritoneum as well as the small intestine mesentery. Recent histological findings indicate that the primary tumor was located at the ileocecal junction and is consistent with an adenocarcinoma. Histological findings also show secondary metastasis to the liver. The lung nodule was found to be a fibrocalcific. Histological analysis of abdominal aorta was found to be atherosclerotic and thrombotic. The cyst on the epidermis of the neck was found to be benign.

CONCLUSION: Research surrounding colorectal adenocarcinoma is still ongoing. We hope to establish the pattern of metastasis as well as the various organs that the adenocarcinoma metastasized to.
