Galli Galli Disease: A Challenging Diagnosis in a Bahraini Female Patient

Dowling-Degos Disease (DDD) is an inherited cutaneous disease which presents with classic and atypical cutaneous findings, including macules of hyperpigmentation and hypopigmentation in the flexural creases. A variant, termed Galli-Galli Disease (GGD), presents similarly, with the distinguishing feature of acantholysis on histology. Reports of GGD in the literature are rare, due to the infrequency of the diagnosis. This may contribute to a lack of available information and delayed diagnosis, which can result in a frustrating clinical course for patients. We present a female patient who presented with complaints of a burning sensation and painful rash for the last three years on a background of hypopigmented and hyperpigmented macules on the trunk, upper extremities and flexural creases. Comprehensive dermatopathological evaluation and clinical correlates led to the diagnosis of GGD.
