The authors present a case of 60-year-old woman, followed-up for melanoma removed eight years ago, with incidental findings of years-long numerous pigmented macules on the trunk and limbs. Histology suggested the diagnosis of morbus Dowling-Degos, with less common finding of horn cysts.
The presence of acantholysis during the revision of biopsy led to the final diagnosis of morbus Galli-Galli, which is considered to be a subtype of genodermatosis morbus Dowling-Degos. The review provides current knowledge about this disease.
