The cornea has a bacterial coating or ulcer

Introduction The corneal infection is characterized by bacterial or ulceration of the cornea. Subcutaneous tissue type of dark filamentous mold can be seen in the subcutaneous tissue with thin pus, and there is exudate in the cyst. If the cyst wall is incompletely removed and the sinus is left, it can be cured for a long time. Phaeohyphomycosis is a group of dark-colored fungi that causes skin, subcutaneous tissue, or systemic infections characterized by dark hyphae in tissues. In 1974 Ajello proposed this name. Dark filamentous mildew has been reported in scattered cases around the world, but it is more common in the tropics. In recent years, there have been reports of sporadic cases in Shandong, Northeast and Zhanjiang. The pathogenic pathways are mainly exogenous infections and conditional pathogenic infections. The route of infection may be the implantation or inhalation of fungal spores by pathogens through skin lesions. The clinical manifestations are shallow ulcers, ecchymoses, brownish black spots or verrucous hyperplasia, consciously itchy or mild pain, and some may have no symptoms. Diagnosis by mycological examination and histopathological examination. Most of them are not sensitive to fungal drugs and have poor efficacy.

According to the performance of skin lesions, the diagnosis of mycological examination and histopathological examination is not difficult. Patients are more likely to work outdoors and are often in contact with such rot. Can be expressed as shallow ulcers, ecchymoses, brownish black spots or verrucous hyperplasia, consciously itchy or mild pain, and some may have no symptoms. Subcutaneous tissue type of dark filamentous mold often has isolated, deep subcutaneous or muscular abscesses or cysts, lesions can be apricot nucleus large or a few centimeters, or even large plaques throughout the chest. Systemic dark filamentous mold This type can be caused by the skin or subcutaneous tissue of the genus Fusarium oxysporum to lymph nodes, lungs, brain and gallbladder, etc., or no skin damage, initial lymph nodes or blood dissemination.

The disease can be divided into the following types:

1. Superficial dark-type Helminthosporium: including palmar black spots and black hair sarcoidosis. Can be expressed as shallow ulcers, ecchymoses, brownish black spots or verrucous hyperplasia, consciously itchy or mild pain, and some may have no symptoms. Black spots on the palm are brown to black scaly patches on the palm and ankle. Even can affect the neck, chest and other parts. Black hair sarcoidosis is the formation of oval small nodules on the hair shaft, hard as a stone, hanging like a scorpion egg or coated on the hair shaft, black. It is not easy to see with the naked eye. Touching with your fingers is like sand. Mainly invades the hair, and secondly in the eyebrows and eyelashes.

Corneal infections are characterized by bacterial or ulcers in the cornea, and the patient is conscious of photophobia, tearing, and visual impairment. When the lacrimal gland is infected, it is characterized by lacrimal duct obstruction, overflowing pus and local granulomatous damage.

2. Subcutaneous tissue type of dark filamentous mildew: often isolated, deep subcutaneous or muscle abscess or cyst, skin lesions can be apricot nucleus or a few centimeters, or even large plaques throughout the chest. At this time, the skin is often affected by brownish red or grayish black. The sputum has a sense of infiltration, the surface is rough, and generally does not rupture. At the time of biopsy, there is a thin pus in the subcutaneous tissue, and there is exudate in the cyst. If the cyst wall is incompletely removed, there is The sinus can not heal for a long time.

3. Systemic dark filament mold: This type can be caused by the skin or subcutaneous tissue of the genus Fusarium oxysporum to lymph nodes, lungs, brain and gallbladder, etc., or no skin damage, initial lymph node or blood dissemination . The incidence of dark-spotted sarcoplasmosis is more urgent. This type of prognosis is poor, often leading to death.

Differential diagnosis

Sometimes it needs to be differentiated from colored germination and Fusarium oxysporum. Coloring geranosis by dark-colored fungi (including Bifidobacterium, Branched genus, Mycobacterium, genus, genus, genus, genus, genus, genus, genus Infections of subcutaneous tissue, sinuses, brain and other tissues caused by genus, Ochroconis, Trichophyton, genus Basidiomycetes and Venom. Common symptoms of the disease include papules, ulcers, and itching. The following information has been compiled for you. Although it does not solve the problem, it can increase your understanding of the disease and can also play a role in health prevention.
