We have examined the clinical characteristics of pigmented macules on palms and/or soles. A total of 238 inpatients and 111 healthy persons over 40 years old in Japan were included in our analysis. We found: (a) that such pigmented macules may occur not only on healthy persons but also on patients who suffer from various internal disorders, (b) that, in both males and females, the incidence of pigmented macules is relatively high in malignancy patients in comparison with non‐malignancy and control individuals, (c) that the incidence is higher in males than in females, (d) that, in both males and females, there was a tendency toward distribution on both palms and soles in malignancy patients in comparison with the non‐malignancy and control individuals (p<0.01), and (e) that, among cases with pigmented macules, the number of pigmented macules is empirically greater in inpatients (the malignancy and non‐malignancy groups) than in the controls.
