Surgical Management and Outcomes of Cutaneous Mold Infections in Immunocompromised Children.

Background Cutaneous mold infections occur infrequently but can be life-threatening in immunocompromised children. The literature regarding its surgical management is limited. This study aims to describe the surgical management and outcomes of cutaneous mold infections in immunocompromised children. Methods Hospitalized patients receiving a skin biopsy at a single pediatric hospital in 2003 to 2017 were identified. Inclusion criteria were immunocompromised status, younger than 21 years, and surgical excision of a confirmed cutaneous mold infection. Patient information, details of immunosuppression, operative details, and 6-month postoperative and disease outcomes were collected. Results Seventeen patients (21 lesions) were identified with an average age of 6.8 years (range = 0.2-19.5 years). Affected anatomic regions included limb (15, 71%), chest (2, 10%), axilla, back, abdomen, and head (1 or 5% each). Excisions occurred, on average, within 1.7 days of initial biopsy (range = 0-7 days). When specified, margins were 0.5 to 2.0 cm, and surgeons used intraoperative fungal detection techniques in 8 cases (47%). Definitive closure was achieved by secondary intention/dressings changes (9, 43%), skin graft (7, 33%), a skin substitute (2, 10%), immediate primary closure (2, 10%), and delayed primary closure (1, 5%). Overall, 14 patients were alive 6 months after resection (82%). Conclusions This study is the first to critically evaluate the methodology for surgical resection of cutaneous fungal infections in immunocompromised children. We suggest timely excision once diagnosed with, at minimum, 0.5-cm margins and intraoperative pathologic study when considering surgical treatment for this rare but serious infection.
