Aspergillosis is the most frequent invasive mold infection in
immunocompromised patients.7 For this patient, in particular,
his long-term habitation in an orchard with probable exposure to
high spore counts,4 frequent incidental cutaneous injuries, and
impaired cutaneous barrier in MF were likely risk factors for
developing this infection.

The Infectious Disease Society of America guidelines specify
three groups of antifungal agents for the treatment of aspergillosis, namely triazoles, amphotericin B, and echinocandin. Triazoles are the preferred agents for most patients.5 Amphotericin
B is often reserved for use in resource-limited settings in which
no alternative agents are available as in the case of our patient.
Scopulariopsis is frequently isolated from onychomycosis
patients. Cutaneous infection is rare but has been reported.4
Several drug susceptibility studies have shown that the organism is resistant to broad-spectrum antifungal agents including
amphotericin B, flucytosine, fluconazole, itraconazole, voriconazole, and terbinafine.6,8,9
Decisions on when to proceed with chemotherapy for MF
should involve both infectious disease specialists and hematologists/oncologists, as they must consider the progression of cutaneous infection during treatment versus the risk of death from
the underlying malignancy if the treatment is delayed.10,11 In
cases such as these, multiple biopsies, fungal cultures, and
MALDI-TOF may be needed to establish the etiology of the
opportunistic pathogens which can present as multiple coexisting infections in a single patient.
Conclusion
Treatment of aspergillosis and scopulariopsis remains difficult,
especially for immunocompromised patients who need to start
chemotherapy because of multiple drug interactions since
most antifungal agents are nephrotoxic. Given the high resistance to antifungal agents and its potential to disseminate in
immunocompromised hosts, treatment of a secondary opportunistic fungal infection serves as a roadblock to therapy.
