Three cases of easy to be misdiagnosed tinea of vellus hair

mycolabadmin

This case report describes three patients (ages 2-24) who had skin infections caused by a fungus called Microsporum canis that initially was misdiagnosed as eczema or other simple skin conditions. The infections involved fine vellus hair and required prolonged combined treatment with both oral and topical antifungal medications to fully resolve. The key lesson is that proper fungal testing and extended treatment similar to scalp ringworm protocols are necessary for treating these easily-missed infections.

Madurella tropicana and Madurella pseudomycetomatis identified as new causative agents of black grain eumycetoma in Senegal

This case report describes two patients in Senegal with a serious fungal infection called eumycetoma caused by previously unidentified fungal species. Using modern DNA sequencing methods, researchers identified the infections as being caused by Madurella tropicana and Madurella pseudomycetomatis, rather than the previously known Madurella mycetomatis. One patient treated with the antifungal drug itraconazole showed good improvement, highlighting the importance of accurate identification for proper treatment.

Approaches to Invasive Fungal Diseases in Paediatric Cancer Centres: An Analysis of Current Practices and Challenges in Germany, Austria and Switzerland

This study examined how 62 children’s cancer hospitals in Germany, Austria and Switzerland manage fungal infections in young cancer patients. Researchers found that hospitals use different methods to prevent and treat these serious infections, with some having special fungal infection experts and others not. The study revealed that larger hospitals tend to have better resources and expertise, while smaller hospitals face challenges like drug interactions and delays in getting test results.

Deep cutaneous fungal infection in an immunocompetent individual caused by a biological pesticide: a rare case report

mycolabadmin

A 66-year-old farmer developed a deep skin fungal infection from a biological pesticide she used for over 10 years. The pesticide contained a fungus called Purpureocillium lilacinum, which is normally harmless to healthy people but caused repeated skin lesions on her face and arms. She was successfully treated with antifungal medication (itraconazole) for three months, and her skin fully healed without returning. This is the first reported case showing that biological pesticides can pose health risks to workers who handle them regularly.

Invasive Cutaneous Mucormycosis in a Patient With Chronic Lymphocytic Leukemia on Obinutuzumab, Idelalisib, and Bruton Tyrosine Kinase Degrader: A Case Report

A 74-year-old man with blood cancer developed a serious fungal skin infection caused by Mucorales while taking multiple targeted cancer drugs. The infection appeared as a darkening ulcer on his ankle that rapidly worsened. Doctors diagnosed it using a skin biopsy showing characteristic fungal structures, though standard fungal tests came back negative. The patient required amputation of his leg below the knee to remove all the infected tissue, along with antifungal medications, and ultimately recovered.

Dermatophytosis caused by Trichophyton benhamiae in a sea lion. First report

mycolabadmin

A 13-year-old sea lion in a marine park developed ringworm-like skin lesions caused by a fungus called Trichophyton benhamiae, marking the first time this fungus has been identified in this species. Scientists identified the fungus using DNA testing and found it was resistant to common antifungal drugs, so they treated it with a combination of oral medication (terbinafine), topical ozonized oil, and a liver-protecting supplement. After three months of treatment, the sea lion’s skin healed completely.

Invasive Rhinocerebral Mucormycosis Is a Rare Complication in Systemic Juvenile Idiopathic Arthritis Patient

A 5-year-old girl with systemic juvenile arthritis being treated with immunosuppressive medications developed a rare and serious fungal infection in her nose and sinuses caused by a mold called Lichtheimia. The infection caused tissue death and spread toward her brain, but was successfully treated with combination antifungal drugs and surgery. This case highlights how powerful immunosuppressive treatments for severe arthritis can increase the risk of life-threatening fungal infections.

Deep cutaneous fungal infection in an immunocompetent individual caused by a biological pesticide: a rare case report

mycolabadmin

A 66-year-old farmer developed recurring skin infections over 10 years from exposure to a biological pesticide containing a fungus called Purpureocillium lilacinum. Although this fungus is generally safe for healthy people, this case shows it can cause serious skin infections with prolonged exposure. The patient was successfully treated with antifungal medication over three months. This case highlights the importance of proper safety measures when working with biological pesticides.

Coexistence of Malassezia Species and Microsporum canis in the Lesions of Adult with Tinea Capitis

mycolabadmin

A 60-year-old woman developed unusual hair loss and scalp inflammation that looked like dandruff but was actually a fungal infection caused by multiple fungi working together. Doctors found three different fungi in her scalp samples: one dermatophyte and two Malassezia species. Lab experiments showed that the Malassezia fungi actually helped the main disease-causing fungus grow better, which explains why the condition looked different from typical cases. After three months of antifungal medication, her symptoms cleared and her hair grew back.

Deep Fungal Infection of the Skin with Two Rare Fungi in a Dog Being Treated with Immunosuppressant Therapy: A Case Report

mycolabadmin

A dog being treated for brain inflammation with immune-suppressing drugs developed a serious skin infection caused by two unusual fungi not previously reported together in veterinary medicine. The infection proved difficult to diagnose, requiring tissue samples and specialized laboratory testing to identify the fungi and determine which antifungal drugs would work best. Despite treatment with antifungal medications and reducing the immunosuppressive drugs, the infection did not improve and the dog’s underlying condition worsened, ultimately requiring euthanasia. This case shows the serious risks of fungal infections in animals on long-term immunosuppressive therapy and highlights the need for careful monitoring and early detection.
