Olmsted syndrome with hypotrichosis

Area of Science:

• Dermatology
• Medical Genetics
• Pediatrics

Background:

• Olmsted syndrome is a rare disorder characterized by mutilating palmoplantar keratoderma and peri-orificial hyperkeratosis.
• It often presents with associated hair abnormalities and can significantly impact mobility.

Purpose of the Study:

• To report a case of Olmsted syndrome in an 8-year-old boy.
• To describe the clinical presentation, diagnostic findings, and treatment response.

Main Methods:

• Clinical examination of skin and hair.
• Light and scanning electron microscopy of hair shafts.
• Assessment of treatment response to oral retinoids and topical keratolytics.

Main Results:

• The patient presented with severe keratoderma, hyperkeratotic plaques, and sparse, easily pluckable hair with shaft abnormalities.
• Lesions were unresponsive to conventional treatments but showed partial improvement with oral retinoids and topical keratolytics.
• Psychomotor development was normal initially, but mobility was restricted due to keratoderma.

Conclusions:

• Olmsted syndrome requires a multidisciplinary approach for management.
• Oral retinoids may offer a therapeutic option for this condition, although response can be partial.
• Further research into genetic and therapeutic aspects is warranted.
