PRP with subcorneal acantholysis: case report and review.
Although the clinical findings of pityriasis rubra pilaris (PRP) are striking, the microscopic diagnosis can be difficult because changes can be subtle and can overlap with other skin diseases. Suprabasal acantholysis can be seen in PRP, mimicking pemphigus vulgaris. We report a patient with PRP whose initial biopsies demonstrated subcorneal acantholysis mimicking pemiphigus foliaceus.
