[A Case of Early Gastric Cancer with Nodular Tumor-like Scalp Metastasis].

Many neoplasms, including lung cancer, breast cancer, melanoma, and gastrointestinal tract malignancy, possess potential for skin metastasis. Skin metastases can represent the first presentation of such malignancies and may be observed incidentally during routine exam. Skin metastases from gastric adenocarcinoma are uncommon, with a prevalence rate of 0.04-0.8%. Cutaneous metastases from gastric cancer are generally observed as the initial symptom of advanced gastric cancer. Early detection and treatment can increase patient survival. A 42-year-old woman visited our department with nodule about 1 cm in size on the right frontal scalp noticed incidentally after laparoscopy-assisted distal gastrectomy and adjuvant systemic chemo-therapy for early gastric cancer about 16 months prior. The patient was diagnosed with skin metastasis from gastric adenocarcinoma. Complete excision of the skin lesion and additional chemotherapy were performed. Herein, we report a case of nodular tumor-like scalp metastasis from early gastric cancer with a brief review of the literature.
