Cutaneous presentation of gastric cancer is very rare. This case report is about a patient with a metastatic gastric cancer in which the diagnosis was made by a cutaneous biopsy. Following this unusual diagnostic tool, the patient had an intracardiac thrombus, during the chemotherapy regimen, which wasn't a contraindication for pursuing chemotherapy treatment for over 12 months. This case report is presented to make clinicians aware of a possible atypical sign of presentation of gastrointestinal tract cancer, as well as the importance of clinical suspicion of a well-known problem affecting cancer patients such as venous thromboembolism and its repercussions in the treatment options.
