Tissue expansion in a patient with extensive nevus comedonicus.
Nevus comedonicus is a rare developmental abnormality of the pilosebaceous apparatus that presents as an aggregation of dilated follicular orifices filled with pigmented keratinous material. Occurrence of extensive or giant lesions is even more rare. Indications for treatment include recurrent infections and cosmetic reasons. Therapeutic approaches include topical keratolytic agents, manual extraction of comedones, dermabrasion, and excision of smaller lesions. Increasing clinical experience with tissue expansion has suggested that it might be used effectively in the definitive treatment of an extensive nevus comedonicus previously considered too large to excise without the use of a skin graft, despite the potential risk of infection within the lesion during the course of expansion. We report the first patient with giant nevus comedonicus to be treated using tissue expansion. This patient demonstrates that prompt treatment of cellulitis and abscesses within the lesion will keep this process isolated from the adjacent expanders and will not compromise a planned excision and reconstruction.
