    Eruptive Disseminated Porokeratosis Associated with Corticosteroid-Induced Immunosuppression
    (Wiley, 2015-10) Bednarek, Robert; Ezra, Navid; Toubin, Yulianna; Linos, Konstantinos; Mousdicas, Nico; Department of Dermatology, IU School of Medicine
    Eruptive disseminated porokeratosis (EDP) is a disease that presents clinically with sudden onset of erythematous papules and plaques, with a ridge-like border histologically represented by a cornoid lamella. We report a case of EDP occurring in a 39-year-old woman 3 days after completion of a 2-week course of oral corticosteroid therapy for an acute asthma exacerbation. The patient was treated with emollients and sun protection. Unlike the more chronic disseminated superficial (actinic) porokeratosis, EDP secondary to immunosuppression from corticosteroid therapy has very rarely been reported in the dermatological literature.

    An unusual presentation of cutaneous histoplasmosis as a recurrent solitary and spontaneously healing lesion in an immunocompetent patient
    (Microbiology Society, 2020) Muldoon, Jessica L.; Wysozan, Timothy R.; Toubin, Yulianna; Relich, Ryan F.; Davis, Thomas E.; Zhang, Chen; Alomari, Ahmed K.; Dermatology, School of Medicine
    Infection with Histoplasma capsulatum typically manifests as a self-limiting pulmonary disease in immunocompetent patients. Systemic symptoms such as cutaneous lesions are associated with immunodeficient states. Our patient was an immunocompetent 68-year-old male who presented with a plaque on his left infraorbital area that was concerning for malignancy. Histological examination of the lesion revealed granulomatous inflammation and small yeast forms suggestive of H. capsulatum. The lesion resolved spontaneously and recurred 1 year later. On recurrence, histological examination again revealed yeast forms consistent with H. capsulatum. Serum and urine testing for H. capsulatum antigen were negative. Next-generation sequencing detected H. capsulatum, which supported the diagnosis of a cutaneous infection. The patient was prescribed and started treatment with itraconazole for 1 year after recurrence of the lesion, and he has not reported further disease recurrence to date. This case is unique because of the presentation of a primary cutaneous recurrent H. capsulatum lesion, and it demonstrated the utility of laboratory testing in its diagnosis.
