This case report details a rare linear manifestation of Darier's disease in a 60-year-old male. The diagnosis was challenging due to the unusual presentation along Blaschko's lines.
Area of Science:
- Dermatology
- Medical Genetics
Background:
- Darier\'s disease is a rare autosomal dominant genodermatosis.
- Typical presentations involve greasy, hyperkeratotic plaques.
- Linear Darier\'s disease is an extremely rare variant.
Observation:
- A 60-year-old male presented with a 6-year history of skin lesions.
- Lesions were brown to red papules and plaques with hyperkeratosis.
- The distribution followed Blaschko\'s lines on the abdomen.
Findings:
- The clinical presentation mimicked other dermatoses, delaying diagnosis.
- Dermatological workup and biopsy were crucial for confirming the diagnosis.
- Histopathology revealed characteristic features of Darier\'s disease.
Implications:
- Highlights the importance of considering rare variants in dermatological diagnosis.
- Emphasizes the diagnostic utility of biopsy in challenging cases.
- Contributes to the limited literature on linear Darier\'s disease.
