Disease: Fungal skin infection

Tinea incognito skin lesions worsen after antifungal treatment: Atypical tinea appearing twice in a case: A case report

A young woman had a persistent facial rash for 10 months that was initially misdiagnosed as dermatitis because early fungal tests were negative. When fungal testing was repeated, it finally confirmed a fungal infection (tinea incognito) caused by contact with a dog. Treatment with antifungal medication alone initially worsened the condition by causing bacterial infection, but combining antifungal and antibiotic medications resolved it. The infection returned after using the same contaminated skincare products, but was successfully treated again with the combined medication approach.

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

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.

Dual-Emission FRET-PCR Outperforms SYBR Green and EvaGreen for Accurate Discrimination of Primary Canine Dermatophytes: Microsporum canis, Nannizzia gypsea, and Trichophyton mentagrophytes

Dogs often get fungal skin infections caused by three main types of fungi. Doctors have traditionally grown these fungi in culture, which takes 2-4 weeks. Scientists have now developed a faster genetic test called FRET-PCR that can identify which fungus is causing the infection in just 2.5 hours. This new test is more accurate and reliable than older genetic tests, helping veterinarians treat infections quickly and prevent them from spreading.

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

An 8-year-old dog receiving long-term immunosuppressive medication for brain inflammation developed rare fungal skin infections caused by two unusual fungi not previously reported together in veterinary medicine. Diagnosis required multiple tests including tissue samples, staining techniques, and genetic testing. Despite treatment with antifungal medications and careful adjustment of immunosuppressive drugs, the infections did not improve, highlighting the difficult balance between fighting infections and controlling the underlying immune disease.

Deep cutaneous phaeohyphomycosis caused by Cladophialophora boppii: A case report

A 69-year-old woman with breast cancer developed a skin infection caused by a rare fungus called Cladophialophora boppii while taking dexamethasone for cancer treatment. Doctors diagnosed the infection through skin biopsy and fungal testing, then removed the infected area surgically. After three weeks of antifungal medication (itraconazole), the infection cleared completely and did not return during four months of follow-up. This case suggests that surgery combined with short-term antifungal treatment may be sufficient for this type of infection.
