Cutaneous protothecosis presenting as recurrent chromomycosis.

T McAnally, E L Parry

    Archives of Dermatology
    |August 1, 1985
    PubMed
    Summary

    Protothecosis can mimic chromomycosis relapse in skin infections. Effective treatment requires distinguishing between these rare conditions, as protothecosis requires different therapies than chromomycosis.

    Area of Science:

    • Dermatology
    • Infectious Diseases
    • Mycology

    Background:

    • Chromomycosis and protothecosis are rare cutaneous infections.
    • Accurate diagnosis is crucial for effective treatment of these conditions.

    Observation:

    • A case is presented where protothecosis clinically and histologically mimicked a chromomycosis relapse.
    • Initial chromomycosis treatment with local excision and ketoconazole was successful.

    Findings:

    • The suspected chromomycosis relapse was confirmed as protothecosis.
    • Protothecosis did not respond to ketoconazole but resolved with amphotericin B and tetracycline hydrochloride.

    Implications:

    • This case highlights the importance of considering protothecosis in the differential diagnosis of recalcitrant chromomycosis.
    • Treatment strategies must be tailored to the specific pathogen, as antifungal monotherapy may be ineffective for protothecosis.
