Summary:Leser-Trelat sign is a paraneoplastic marker characerized by the abrupt appearance of seborrheic keratoses. It is described in association with many underlying malignant diseases. We report a case of coexistence of two rare entities, represented by the Leser-Trelat sign occurring with male breast cancer. The asscociation of male breast cancer and LT sign is decidedly unusual.
