Linear seborrheic keratoses associated with underlying malignancy.
A clinical syndrome, consisting of eruptive linear seborrheic keratoses associated with adenomatous colonic polyps (malignant but without invasion of the stalk) and/or frankly invasive colonic adenocarcinomas, is described in five patients. Partial to almost complete regression of the cutaneous lesions over the succeeding months to years was noted after removal of the internal malignant tumors in all five patients. Resolving lesions were characterized by an accentuation of chronic inflammatory infiltrate both within the epidermis and dermis, suggesting perhaps that the regression of the skin lesions may be related to enhanced immunologic response concomitant with the removal of the underlying malignancy.
