Cutaneous metastasis from gastric cancer: Manifestation, diagnosis, treatment and prognosis

Introduction:
Cutaneous metastasis from gastric cancer is very rare. The understanding of this disease is incomplete. This situation delays its diagnosis and treatment, followed by poor prognosis. Here, we first report a study based on a network to improve the diagnosis, treatment and prognosis of cutaneous metastasis from gastric cancer.
Methods:
A comprehensive search of PubMed was performed. All studies on cutaneous metastasis from gastric cancer were collected. The publication date was limited from 2000 to the present, and the language was limited to English. SPSS 26.0 was employed for statistical analysis.
Results:
Seventy-two patients were included. The average patient age was 60.0 ± 16.0 years. In total, 72.2 % of the patients were male. The most common manifestation was nodular skin lesions (45.8 %). The metastases generally presented as multiple lesions (61.1 %). The most common metastasis location was the thoracoabdominal wall (56.9 %). 64.7 % of the patients simultaneously had extracutaneous metastases. Most of the tumors were poorly differentiated carcinomas (87.5 %), and 66.1 % had signet ring cells. 40.8 % of the cutaneous metastases presented as primary manifestations. Only 9.6 % had their diagnosis as soon as the cutaneous metastasis emerged. Systemic chemotherapy (65.6 %) was the most common treatment strategy, followed by radical surgery (12.5 %). The median overall survival was only 6 months. The median overall survival of 5 patients with resected tumors was 48 months.
Conclusion:
Cutaneous metastasis from gastric cancer usually manifests as an emerged nodule or erysipelas-like skin lesion. Resection of the cutaneous lesion could be helpful for patients with local metastases.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
