Prurigo nodularis associated with advanced gastric cancer: report of a case

In a male Japanese patient, prurigo nodularis (PN) appeared in association with gastric cancer. The cutaneous pruriginous lesions dramatically improved soon after total gastrectomy without any treatment for the skin lesions. Peripheral eosinophilia seen before the operation also rapidly disappeared. These data suggest that some cytokines involved in gastric cancer might have played an important role in the development of PN in our patient.
