Acromelanosis Albo-Punctata: A Distinct Inherited Dermatosis with Acral Spotty Dyspigmentation without Systemic Involvement
We describe an otherwise healthy 7-year-old boy who developed confetti-like hypopigmented macules on the dorsal aspects of the hands and feet, spreading to the palms and soles a few months after birth. In 1964 Siemens introduced the term acromelanosis albo-punctata to describe the skin features of a patient who has remained the only reported case in the literature so far and who strongly resembles our patient. By genetic testing we excluded mutations in genes known to be involved in diseases with acral hypo- or hyperpigmentation. We review the differential diagnosis of acral localized spotty dyspigmentation and conclude that acromelanosis albo-punctata may represent a distinct entity.
