    Primary infection in most cases of dimorphic fungi is _________.

    • Cardiac infection

    • Gastro infection

    • Pulmonary infection

    Correct Answer
    A. Pulmonary infection
    Explanation
    Dimorphic fungi are a group of fungi that can exist in two different forms depending on the environmental conditions. In most cases, the primary infection caused by dimorphic fungi occurs in the lungs, leading to a pulmonary infection. This is because the spores or conidia of these fungi are usually inhaled, and the lungs provide a suitable environment for their growth and colonization. Once established in the lungs, the fungi can cause respiratory symptoms and potentially spread to other organs in the body.

    Infections from fungi occur mostly due to:

    • Disruption of natural barriers

    • Immunosuppression

    • Occupational contact

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Infections from fungi can occur due to a combination of factors. Disruption of natural barriers, such as damaged skin or mucous membranes, can make it easier for fungi to enter the body and cause infection. Immunosuppression weakens the immune system's ability to fight off infections, including fungal infections. Occupational contact with fungi, such as working in environments with high fungal exposure or handling contaminated materials, can also increase the risk of fungal infections. Therefore, all of these factors can contribute to the occurrence of fungal infections.

    A pathologist receives a surgical specimen taken from a 12-year-old boy. The submitted history is not helpful. The specimen is processed for histopathology and the pathologist submits the following report. The specimen was one cm in diameter and nodular. The cut surface revealed a central region of white creamy material surrounded by a rim of firm tissue. Microscopically, the central region consisted of neutrophils, some of which were apoptotic. The neutrophils were surrounded by a capsule of proliferating granulation tissue. What is your diagnosis?

    • Abscess

    • Benign neoplasm

    • Cellulitis

    • Granuloma

    • Infarct

    Correct Answer
    A. Abscess
    Explanation
    The correct answer is Abscess. The description of the specimen, including the presence of a central region of white creamy material surrounded by a rim of firm tissue, along with the microscopic findings of neutrophils and proliferating granulation tissue, are consistent with an abscess. An abscess is a localized collection of pus within a tissue, typically caused by a bacterial infection. The presence of neutrophils and apoptotic neutrophils further supports the diagnosis of an abscess.
