Abstract: The data of 62 patients with cutaneous metastatic carcinoma in the dermatology department of our hospital from January 2010 to January 2021 were retrospectively analyzed. Among the 62 patients, 34 cases were male (54.8%) and 28 cases were female (45.2%).The mean age of onset was 59.2±12.5 years old (41~89 years old). The median patient visit time was 2 months. There were 45 cases (72.6%) with only one metastatic lesion, and 17 (27.4%) with two or more metastases. The most common sites were chest (18 cases), head (14 cases), and limbs (12 cases). Most of the lesions were nodules and masses (49 cases), followed by erythema (9 cases) and papules (4 cases). Among the primary tumors, 56 cases (90.3%) were metastatic adenocarcinoma, 4 (6.5%) were metastatic squamous cell carcinoma, and 2 were small cell carcinoma. Lung cancer was the most common tumor in males, and breast cancer was the most common tumor in females. Nineteen of the 62 cases were misdiagnosed as other diseases, and the misdiagnosis rate of the first diagnosis was 30.6%. Cutaneous metastatic carcinoma is easy to be misdiagnosed clinically and vigilance should be raised.
