Color blastomycosis and hyphomycosis

Introduction to coloring blastomycosis and dark filamentous mildew Fungus from dark color (including Bifidobacterium, Mycobacterium, Mycobacterium, genus, genus, genus, genus, genus, genus, genus, genus, Ochroconis, Infection of subcutaneous tissue, sinuses, brain and other tissues caused by Trichophyton, genus Basidiomycetes and V. genus. Coloring germination is an invasive granulomatous fungal disease caused by different kinds of coloring fungi invading the skin and subcutaneous tissue. The main pathogenic bacteria are soil bottom bacteria, which can enter the human body through skin trauma, and can be inoculated spontaneously. Hematogenous dissemination, the disease mostly occurs in temperate and tropical areas, the course of disease is prolonged, can cause physical disability. Infection of subcutaneous tissue, sinuses, brain and other tissues caused by dark colored fungi. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: pruritus

Coloring blastomycosis and the cause of dark filamentous mildew

Bacterial infection (85%):

Coloring germination is an invasive granulomatous fungal disease caused by different kinds of coloring fungi invading the skin and subcutaneous tissue. The main pathogenic bacteria are soil bottom bacteria, which can enter the human body through skin trauma, and can be inoculated spontaneously. Blood line spread,

Environmental factors (15%):

The disease occurs mostly in temperate and tropical regions, and the course of disease is prolonged and can cause physical disability. Infection of subcutaneous tissue, sinuses, brain and other tissues caused by dark colored fungi.

Coloring blastomycosis and prevention of dark filamentous mildew

1. Wear shoes and avoid skin contact with the soil.

2, pay attention to prevent trauma, early detection of damage and timely treatment.

Coloring blastomycosis and dark filamentous mildew complications Complications pruritus

Complications can cause limb destruction or affect function, and can also form elephantiasis. Very few can spread to distant skin or internal organs, especially the central nervous system, which can also cause death, but it is rare.

Symptoms of coloring blastomycosis and dark filamentous mildew common symptoms chest plaque papules itching

Late colorimetric spore lesions have a characteristic appearance, but early lesions may be misdiagnosed as dermatophytosis. Dark filamentous mildew must be distinguished by histopathology and culture, as well as facial skin infections and non-infectious diseases caused by numerous other causes. Ordinary hematoxylin and eosin-stained tissue specimens are easily recognizable as dark-colored fungi, which are separated by a tan body that reflects its natural black component. Masson-Fonana melanin staining determines its presence. In order to identify pathogenic bacteria, culture is required.

Examination of pigmented blastomycosis and dark filamentous mildew

1. Laboratory examination : Direct microscopic examination can be seen in brown, and the thick-walled scorpion is called split body. No filth is found. The fungus culture has dark fungus growth.

2, histopathological examination: only invade the epidermis, dermis, does not invade the subcutaneous tissue, the epidermis is pseudoepithelial neoplasia, epidermis, small abscess in the dermis, small brown and hard shells in different forms in small abscesses and heterogeneous multinucleated giant cells Cells (thick walled).

Diagnosis and identification of colored buds and dark filamentous mildew

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

1, verrucous skin tuberculosis is more common in adult males, occurs in the hands, feet, upper arm and other exposed parts, has a history of trauma, early rash is a single dark red papules or sickle nodules, hard. After the rash gradually enlarged papillary-like hyperplasia, the surface may have superficial ulcers, the formation of atrophic scars in the center, histopathology is epidermal hyperplasia, dermal tuberculosis granuloma, direct microscopic examination of fungi.

2, foot swelling often has a history of trauma, occurs in frequent contact with the soil, the skin lesions are dark red infiltrative granuloma plaques, can form a sacral tract, from which the granules can be discharged, the fungus directly visible sputum can be seen .
