Large patches on the chest

Introduction Patients with dark filamentous mold are more common in outdoor work and those who are often exposed to such decay. 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. It is a skin, subcutaneous tissue or systemic infection characterized by dark hyphae in tissues caused by dark fungi.

Cause

(1) Causes of the disease

It is a skin, subcutaneous tissue or systemic infection characterized by dark hyphae in tissues caused by dark fungi.

(two) pathogenesis

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.

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.

Mycological examination: taking various kinds of pus and tissue fluids in different lesions, after treatment with 10% potassium hydroxide solution, various forms of brown and dark brown hyphae and yeast-like spores can be seen under the microscope, no thick-walled spores (walls) Brick-like body). Tissue and pus cultures can be grown to produce brown and black fluff-like or yeast-like colonies.

HE staining can be found in most separated, black-walled hyphae, 1.5 to 3 m in diameter, occasionally branched or yeast-like blasts, inflammatory cells or multinucleated giant cells infiltrated around hyphae, no thick-walled spores (wall Brick-like body).

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, the sinus is left.

Differential diagnosis

Chest acne: From the perspective of Chinese medicine theory, acne in different parts is the external manifestation of different visceral dysfunction in the human body. Chest acne is caused by endocrine disorders. There are many causes of chest acne, such as the bra is not very breathable, there is sebum oil caused by pore blockage, and there is imbalance in the body's hormone secretion, etc., making women's chest acne, Pre- or post-menopausal intake of spicy, irritating food, emotional irritability, irritability, etc. can lead to chest acne.

Even the chest: severe closed chest injury caused multiple rib fractures, which caused the local chest wall to lose rib support and soften, and abnormal breathing, that is, in the softened area, the chest wall was invaded when inhaling, and the external protrusion was called the sacral chest during exhalation. Even the chest is often associated with pulmonary contusion, and is an important factor in the induction of acute respiratory distress syndrome (ARDS).

A round or substantial cystic mass in the lung: a teratoma of lung is a rare benign lung tumor that refers to a mediastinal teratoma that originates in the lung. In recent years, there have been several reports in China. The intrapulmonary teratoma may be a vagus embryogenic tissue that descends along the bronchus and is a tumor formed by the lung embryo base. The intrapulmonary teratoma is located in the lung parenchyma, or in the bronchial lumen, mostly rounded or cystic masses, varying in size. The patients were more than 30 years old, and the number of males and females was similar. No hemoptysis, fatigue, weight loss, chest pain and other symptoms. I often see a doctor because of a secondary infection. There may be a clubbing. X-ray examination is mostly the surface of secondary lesions, such as lung abscess, bronchiectasis, atelectasis and so on. 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.
