BACKGROUND. Colorectal cancer (CRC) is a common tumor in the general population, however the overall incidence has decreased due to the implementation of early detection guidelines. The presence of cutaneous metastasis in colorectal adenocarcinoma occurs in only 0.5% of cases, without specific characteristics, and can be underdiagnosed as benign lesions. The presence of cutaneous lesions secondary to colorectal adenocarcinoma implies advanced stages of the disease. The histopathological study accompanied by an immunohistochemical panel is essential to differentiate CRC. Unfortunately, the presentation of cutaneous metastasis confers a poor prognosis for the patient and high short-term mortality. We report the case of a female patient with a single skin lesion on the right arm as the initial manifestation of colorectal adenocarcinoma.
