Mycetoma is a chronic suppurative disease of the skin and subcutaneous tissue, characterized by a symptomatic triad: tumor, fistulas and grains. It can be caused by fungi (eumycetoma) and bacteria (actinomycetoma), with similar clinical features. Diagnosis is based on the clinical presentation and identification of the etiological agents in the tissue, by mycological/bacteriological, histopathological and immunohistochemical tests. Read More

Aspergilloma, also known as mycetoma or fungus ball, is characterized by a round or oval mass with soft-tissue attenuation within a preexisting lung cavity. The typical computed tomography (CT) aspect of an aspergilloma is a mass separated from the wall of the cavity by an airspace of variable size and shape, resulting in the air crescent sign, also known as the meniscus sign. This CT feature is non-specific and can be simulated by several other entities that result in intracavitary masses. Read More

Identification of dematiaceous fungi responsible for black-grain mycetoma has remained cumbersome and time consuming for years leading to delayed diagnosis and thereby increased agony to patients. Moreover, difficult morphology of some of these fungi demanding enough expertise for species identification in addition to culture-negativity has often led to misdiagnosis and hence inapt treatment to the patients. We report the identification of Madurella mycetomatis from culture-negative black granules discharged from foot nodular lesions of a 27 years old male using PCR followed by sequencing of the internal transcribed spacer region.

Mycetoma is a tropical neglected disease characterized by large subcutaneous lesions in which the causative organisms reside in the form of grains. The most common causative agent is Madurella mycetomatis. Antifungal therapy often fails due to these grains, but to identify novel treatment options has been difficult since grains do not form in vitro. Read More

Fungi often infect mammalian hosts via the respiratory route, but traumatic transcutaneous implantation is also an important source of infections. Environmental exposure to spores of pathogenic fungi can result in subclinical and unrecognised syndromes, allergic manifestations, and even overt disease. After traumatic cutaneous inoculation, several fungi can cause neglected mycoses such as sporotrichosis, chromoblastomycosis, mycetoma, entomophthoramycosis, and lacaziosis. Read More

Fungi must meet four criteria to infect humans: growth at human body temperatures, circumvention or penetration of surface barriers, lysis and absorption of tissue, and resistance to immune defenses, including elevated body temperatures. Morphogenesis between small round, detachable cells and long, connected cells is the mechanism by which fungi solve problems of locomotion around or through host barriers. Secretion of lytic enzymes, and uptake systems for the released nutrients, are necessary if a fungus is to nutritionally utilize human tissue. Read More
