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

mycolabadmin

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.

Endogenous Endophthalmitis: An underestimated serious complication in patients with disseminated fusariosis

An 18-year-old boy with acute leukemia developed a serious fungal infection caused by Fusarium mold that spread throughout his body, including to both eyes. Despite receiving intensive antifungal medications injected directly into his eyes along with systemic treatment, he lost his vision. However, through aggressive combined therapy, doctors were able to save both eyes and continue his cancer treatment successfully.

Photo Quiz: A cutaneous fungal infection with discordant biomarker results—a diagnostic challenge

A woman with advanced HIV infection presented with skin sores and respiratory symptoms that were initially suspected to be a viral infection. Testing revealed she had histoplasmosis, a serious fungal infection caused by Histoplasma capsulatum that had spread throughout her body affecting her skin, lungs, and lymph nodes. While standard tests for this fungus were negative, other fungal markers and cultures eventually confirmed the diagnosis, and she was treated with antifungal medications.

Clinical aspects and recent advances in fungal diseases impacting human health

Fungal infections are becoming a major health threat, affecting over a billion people worldwide. The main problems are difficulty diagnosing these infections, increasing resistance to current medications, and limited treatment options. Doctors and the public need better awareness, and new antifungal drugs with different approaches are needed to effectively treat resistant infections.

Disseminated mucormycosis leading to a fatal gastrointestinal perforation in a pediatric case of EBV-associated Hemophagocytic lymphohistiocytosis

A 12-month-old girl developed a serious immune system disorder called hemophagocytic lymphohistiocytosis triggered by Epstein-Barr virus infection. Despite aggressive treatment, she developed a life-threatening fungal infection caused by mucormycosis that spread throughout her digestive system. The case illustrates how fungal infections can rapidly progress and become fatal in children with severely weakened immune systems, emphasizing the need for doctors to recognize early warning signs like tissue darkening on the skin.

Geotrichosis Due to Magnusiomyces capitatus: A Severe Emerging Invasive Fungal Disease

A 71-year-old man with cancer undergoing chemotherapy developed a rare and serious fungal blood infection caused by Magnusiomyces capitatus. Despite treatment with antifungal medications, the infection spread throughout his body and he died 10 days after admission. This case highlights how some fungi can resist common antifungal drugs and the importance of quickly identifying the exact type of fungus causing an infection to choose the right treatment.

Pulmonary Mucormycosis in Diabetic Patients: A Case Series From a Tertiary Respiratory Center in Sri Lanka

This case study describes three patients with diabetes who developed a serious lung infection caused by a rare fungus called mucormycosis. The infection presented with various symptoms like cough, fever, and weight loss, and was diagnosed using lung tissue samples that showed the characteristic fungal structures. Two patients recovered with prolonged antifungal medication treatment, while one patient unfortunately died despite receiving prompt treatment, highlighting how serious this infection can be.

Invasive nasal and paranasal mucormycosis in a patient with severe dengue fever and multiple risk factors: A case report and literature review

mycolabadmin

A 50-year-old woman in Vietnam developed a rare and deadly fungal infection called mucormycosis while recovering from dengue fever. She had weakened immunity from taking steroids for other conditions and from the dengue virus itself. The infection caused black, dead tissue to rapidly spread in her nose and around her eye. Despite treatment with antifungal medications, the infection progressed, and she died within days. The case shows how important it is to watch for dangerous opportunistic infections in dengue patients, especially those already dealing with weakened immune systems.

Polymerase Chain Reaction on Respiratory Tract Specimens of Immunocompromised Patients to Diagnose Pneumocystis Pneumonia: A Systematic Review and Meta-analysis

mycolabadmin

This study analyzed how well PCR tests detect Pneumocystis pneumonia, a serious fungal lung infection in immunocompromised patients. The research reviewed 55 studies with over 11,000 tests and found that PCR testing of fluid from the lungs or induced sputum works very well, especially at ruling out the disease when negative. However, positive test results need careful interpretation because the test can detect the fungus even when it’s just colonizing rather than causing active infection.

Odontogenic-onset mucormycosis: A case series from a tertiary care institute in North India

mycolabadmin

Mucormycosis is a serious fungal infection that can develop after dental procedures like tooth extraction or root canal therapy, especially in people with poorly controlled diabetes. This case study from India describes five patients who developed this infection within weeks of dental work. The infection destroys bone in the upper jaw and palate but usually doesn’t spread to the sinuses like other forms of mucormycosis. All patients improved with antifungal medications and surgical cleaning, highlighting the importance of proper sterilization during dental procedures.
