Mohs micrographic surgery for fungal soft tissue infections.

BACKGROUND

Invasive fungal infections of the integument are relatively rare. In the immunocompromised patient, however, they may show an extremely aggressive biological behavior despite high dosed topical or systemic antifungal therapy. As the fungal tissue invasion usually reaches well beyond the area of clinical necrosis or other visible changes, standard surgical excision often proves to be inadequate, resulting in the need for repeated relatively wide excisions with the resulting substantial loss of initially healthy tissues.

OBJECTIVE

To present the use of Mohs surgery as a safe and effective treatment modality for invasive fungal infections in a patient with a zygomycetes infection of his scalp.

RESULTS

The micrographic excision of the highly aggressive fungal infection, the acute postoperative course, and the delayed reconstruction with a split-thickness skin graft were all well tolerated without complications.

CONCLUSION

Mohs micrographic excision deserves serious consideration in the treatment of aggressive localized fungal infections.
