Abstract
A 78-year-old man had been treated under the diagnosis of chronic eczema by a local dermatologist. Skin eruptions became erythrodermic four months prior to the referral to our clinic. Seborrheic keratoses were reported to have appeared on his head, neck, chest, and back and increased rapidly in number. Laboratory examination revealed multiple colon cancers and lymphomatoid papuloses on his left thigh. The association of these three (erythroderma, multiple colon cancer, lymphomatoid papulosis) is found to be rare. [Skin Cancer (Japan) 2005; 20: 249-253]
