Lymphocutaneous chromoblastomycosis

Last edited: 4/15/2026

Overview

Chromoblastomycosis is a chronic fungal infection caused by dematiaceous fungi, characterized by localized skin lesions that can extend along lymphatic vessels, forming lymphocutaneous spread. 1

Diagnosis

  • Clinical presentation includes papules, nodules, and ulcerations that may disseminate along lymphatic channels.
  • Histopathological examination essential, showing characteristic Medlar bodies (Keratinohyalin granulocytes).
  • Ultrastructural analysis can reveal variability in Medlar body features, reflecting host-fungal interactions. 2
  • Management

  • First-line treatments include systemic antifungal agents such as itraconazole or terbinafine.
  • Cryosurgery has shown efficacy but may result in depigmentation and cosmetic concerns. 3
  • Surgical excision may be considered for localized lesions, though lymphatic spread complicates complete removal.
  • Special Populations

  • No specific guidelines provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts. 13
  • Key Recommendations

  • Confirm diagnosis through histopathological examination with identification of Medlar bodies. (Evidence: Moderate 2)
  • Initiate treatment with systemic antifungals like itraconazole or terbinafine for optimal efficacy. (Evidence: Moderate 1)
  • Consider cryosurgery for localized lesions, acknowledging potential cosmetic drawbacks. (Evidence: Weak 3)
