Aspergillus species can cause a group of superficial and cutaneous mycoses: distal lateral subungual onychomycosis, proximal subungual onychomycosis, otomycosis, and cutaneous …
Aspergillus (Galactomannan) Antigen, Serum
Invasive aspergillosis (IA) is a severe infection that occurs in patients with prolonged neutropenia, following transplantation or in conjunction with aggressive immunosuppressive regimens (eg, prolonged corticosteroid usage, chemotherapy). The incidence of IA is reported to vary from 5% to 20% depending on the patient population.
Aspergilloma
Continuing Education Activity. An aspergilloma is a fungus ball or mycetoma composed of Aspergillus hyphae along with cellular debris and mucus. It is a noninvasive type of chronic pulmonary aspergillosis. Aspergillus species colonize the preexisting cavity in the lung parenchyma and form a fungus cavity.

Articles from Journal of Craniovertebral Junction & Spine are provided here courtesy of Wolters Kluwer -- Medknow Publications. Aspergillus spinal epidural abscess (ASEA) is a rare entity that may mimic Pott's paraplegia as it commonly affects immunocompromised patients. We present one institutional case of ASEA with …
Aspergillosis
These drugs are the standard treatment for invasive pulmonary aspergillosis. The most effective treatment is a newer antifungal drug, voriconazole (Vfend). Amphotericin B is another option. All antifungal drugs can have serious side effects, including kidney and liver damage. Interactions between antifungal drugs and other medications are also ...

The clinical spectrum of pulmonary aspergillosis | Thorax
The clinical presentation of Aspergillus lung disease is determined by the interaction between fungus and host. Invasive aspergillosis develops in severely immunocompromised patients, including those with neutropenia, and increasingly in the non-neutropenic host, including lung transplant recipients, the critically ill patients and patients on steroids. A …
Practice Guidelines for the Diagnosis and Management of
Aspergillus species continue to be an important cause of life-threatening infection in immunocompromised patients. This at-risk population is comprised of patients with prolonged neutropenia, allogeneic hematopoietic stem cell transplant (HSCT), solid organ transplant (SOT), inherited or acquired immunodeficiencies, corticosteroid use, …
