Abstract
Dowling-Degos disease (DDD) is an extremely rare hereditary skin condition characterized by the development of painless, small-sized pigmented patches known as macules or keratotic papules. Typically inherited in an autosomal dominant manner, DDD primarily manifests in adulthood, with onset occurring between the ages of 30 and 40 years, and a higher prevalence among females. Although DDD shares clinical similarities with other reticulated pigmentary disorders such as dyschromatosis symmetrica hereditaria, dyschromatosis universalis hereditaria, and reticulate acropigmentation of Kitamura, its distinctive histopathological features set it apart. A 50-year-old female patient presented with hyperpigmented lesions since infancy, predominantly located in flexural areas, prompting consideration of endogenous eczema or DDD. Despite the absence of a family history and normal laboratory test results, a biopsy confirmed the diagnosis based on characteristic histological findings. The identification of DDD underscores the importance of considering rare dermatological entities in differential diagnosis, especially when clinical presentation aligns with established criteria. Further research and awareness are essential for enhancing our understanding and management of this intriguing skin condition.
