The current report presents an extremely rare case of a 41-year-old female with advanced gastric cancer who developed scalp metastasis during the period of systemic chemotherapy. The patient did not exhibit any rash or plaque at the initial physical examination. Following the 11th cycle of chemotherapy, the patient complained of pain on the scalp and a pink lesion was identified in the parietal region on physical examination, which increased in size and became darker and ulcerated. Pathological biopsy of the lesion and cranial magnetic resonance imaging confirmed the diagnosis of scalp metastasis. The patient succumbed to the disease one month later. The English literature was searched in the PubMed database and four cases of gastric cancer metastatic to the scalp were found. The present report discusses the common clinical presentations of these four cases in combination with the current case.
