Dowling Degos disease in association with multiple seborrhoeic warts

Area of Science:

• Dermatology
• Medical Genetics

Background:

• Dowling Degos disease is a rare genodermatosis characterized by reticulate hyperpigmentation.
• Typical histopathological findings include follicular occlusion and a characteristic pattern of pigment incontinence.

Observation:

• A patient presented with histopathological features consistent with Dowling Degos disease.
• This patient exhibited atypical clinical manifestations not commonly associated with the condition.
• Other family members displayed similar clinical and histopathological patterns.

Findings:

• The histopathology confirmed Dowling Degos disease.
• Unusual clinical features were observed in the proband and family members, suggesting potential phenotypic variability.
• Familial occurrence highlights a possible genetic component influencing disease presentation.

Implications:

• This case expands the understanding of Dowling Degos disease's clinical spectrum.
• Further research may elucidate the genetic factors contributing to the unusual clinical features.
• Recognizing phenotypic variability is crucial for accurate diagnosis and genetic counseling in affected families.
