Invasive Pulmonary Infection of Malassezia Species in a Patient With Ulcerative Colitis: A Case Report.
J Thorac Imaging
November 2024
Department of Diagnostic and Interventional Radiology.
Malassezia species are lipophilic yeasts recognized for causing skin manifestations, such as pityriasis versicolor. In addition, Malassezia can lead to invasive infection, mostly intravascular catheter-associated sepsis-related lipid-containing total parenteral nutrition in neonates and immunocompromised hosts. We experienced a case of invasive pulmonary Malassezia infection in a patient with refractory ulcerative colitis undergoing immunosuppressive treatment without lipid-containing total parenteral nutrition.

Article Synopsis
- Malassezia are yeast species that naturally live on healthy skin but can contribute to various skin disorders, especially in kids.
- This review covers several skin conditions linked to Malassezia in infants, children, and adolescents, like pityriasis versicolor and seborrheic dermatitis.
- The authors analyze existing research to provide insights on these conditions, including their symptoms, diagnosis, risk factors, treatment options, and theories on how Malassezia contributes to their development.

Article Synopsis
- The study investigates the virulence factors of Malassezia furfur, focusing on its role in bloodstream infections (BSI) and its activity in pityriasis versicolor (PV).
- M. furfur strains from BSI patients exhibited higher biofilm production compared to those from PV patients, but displayed lower enzymatic activities like phospholipase, lipase, and hemolysin.
- Antifungal susceptibility testing revealed that drugs like itraconazole and posaconazole were most effective against M. furfur, with minimum inhibitory concentrations indicating a stronger resistance profile in strains from BSI patients compared to those from PV patients.
Pityriasis rosea in pregnancy: A case series and literature review.

July 2022
Department of Dermatology and Venereology, Medical University of Graz, Austria.
Background And Objective: Pityriasis rosea (PR), a common skin disease in young adults, may adversely affects the course of pregnancy and the unborn child.
Patients And Methods: Data from forty-six pregnant women with PR seen in the dermatological university clinic between 2003 and 2018 were analyzed and compared with patient data (n = 53) from previously published studies to determine the incidence and risk factors for an unfavorable pregnancy outcome after PR infection.
Results: Unfavorable pregnancy outcomes (defined as miscarriage, preterm delivery before week 37 of gestation, or birth weight < 2,500 g) were significantly less frequent in our study population than in a pooled cohort obtained from previously published studies (10.
