Last edited: 4/16/2026

Overview

Eosinophilic pustular folliculitis (EPF) is a rare inflammatory skin disorder characterized by pruritic, circinate plaques featuring follicular papules and pustules, predominantly affecting the face, trunk, and arms 1.

Diagnosis

  • Clinical Presentation: Pruritic circinate plaques with follicular papules and pustules 1.
  • Histopathology: Biopsy shows eosinophil and neutrophil infiltration within hair follicles, dermis, and epidermis 1.
  • Laboratory Findings: Peripheral leukocytosis and eosinophilia are common 1.
  • Management

  • First-Line Treatment:
  • - Prednisolone: Oral prednisolone is often used, typically starting at 0.5-1 mg/kg/day 1.
  • Adjunctive Treatments:
  • - Antibiotics: May be considered for secondary infections 1. - Immunosuppressive Agents: In refractory cases, agents like cyclosporine or dapsone might be necessary 1.

    Special Populations

  • Pediatrics: No specific pediatric considerations mentioned 1.
  • Elderly: No unique considerations noted for elderly patients 1.
  • Comorbidities: Management adjustments for patients with comorbidities are not specified 1.
  • Key Recommendations

  • Initiate treatment with oral prednisolone at 0.5-1 mg/kg/day for symptomatic relief and disease control (Evidence: Moderate 1).
  • Monitor peripheral blood counts for eosinophilia and leukocytosis to guide treatment response (Evidence: Expert opinion 1).
  • Consider immunosuppressive therapy such as cyclosporine or dapsone for patients who do not respond to corticosteroids (Evidence: Weak 1).
