Dark filariasis is most common in people who work outdoors and are in constant contact with such decaying matter. It may present as shallow ulcers, petechiae, brownish-black spots, or warty growths, and may be characterized by a slight itch or mild swelling or pain, or may be asymptomatic. The subcutaneous tissue type of dark filariasis often has isolated, deep subcutaneous or muscular abscesses or cysts, and the lesions may be as large as an apricot kernel or several centimeters, or even a large plaque over the entire chest. Patients are most often seen in those who work outdoors and are in constant contact with such putrescences. They may appear as shallow ulcers, petechiae, brownish-black spots, or warty growths, and may be slightly itchy or mildly distended, or may be asymptomatic. Subcutaneous tissue-type dark filariasis often has isolated, deep subcutaneous or muscular abscesses or cysts, and the lesions may be as large as an apricot kernel or several centimeters, or even a large plaque over the entire chest. Systemic dark aspergillosis this type can be caused by the skin or subcutaneous tissue dark aspergillosis spread to the lymph nodes, lungs, brain and gallbladder, etc., can also have no skin damage, the initial that lymph node or blood dissemination. Mycological examination: take pus and tissue fluid from different damages, after treatment with 10% potassium hydroxide solution, various forms of brown and black-brown mycelium and yeast-like spores can be seen under the microscope, and thick-walled spores (walled bricks) are not seen. Tissue and pus were taken for culture, and brown and black fluffy or yeast-like colonies could be grown. HE staining can be detected in the majority of separated, black-walled hyphae, 1.5-3?m in diameter, occasionally branchable or yeast-like germinating spores, hyphae surrounded by inflammatory cells or multinucleated giant cell infiltration, no thick-walled spores (mural bricoliths). Biopsy can be seen in the subcutaneous tissue with dilute pus, exudate in the cyst, if the cyst wall excision is incomplete, leaving a sinus tract. Chest acne: From the perspective of Chinese medicine theory, acne in different parts of the body is the external manifestation of the dysfunction of different internal organs. Chest acne is caused by endocrine disorders. There are many causes of acne on the chest, such as the lack of breathability of the bra, clogging of pores due to excessive sebum, hormonal imbalance in the body, excessive intake of spicy and stimulating foods before or during menstruation, and emotional irritability and restlessness, all of which can lead to acne on the chest. Yoke Chest: Severe closed chest injuries resulting in multiple rib fractures, resulting in softening of the local chest wall without rib support and abnormal breathing, i.e., the softened area of the chest wall sinks in during inhalation and protrudes outward during exhalation, is called Yoke Chest. Shackle chest is often associated with pulmonary contusion and is an important factor in the development of acute respiratory distress syndrome (ARDS). Round, solid or cystic mass in the lung: teratoma of lung is a rare benign tumor of the lung that originates in the lung without teratoma in the mediastinum. In recent years, several cases have been reported in China. Intrapulmonary teratoma may be the vagus embryonic tissue, along the bronchus downstream, for the lung embryonic base encapsulation formation of tumor. Intrapulmonary teratoma is located in the lung parenchyma, or in the bronchial lumen, and is mostly a round, substantial or cystic mass of varying sizes. The age of the patients is more than 30 years old, and the number of male and female cases is similar. There were no symptoms such as coughing up blood, fatigue, emaciation and chest pain. They are often seen for secondary infections. There may be pestle finger.X-ray examination is mostly the surface of secondary lesions, such as lung abscess, bronchial dilatation, pulmonary atelectasis. Attention to improve the body’s immunity, especially cellular immunity, can use immunomodulatory drugs. (I) Treatment 1, local treatment For limited skin and subcutaneous damage as well as keratitis and sinusitis, surgical excision is appropriate, but it should be complete to avoid re-implantation of the organism. In addition, local heating therapy can also be applied. Black hair nodular disease is commonly treated by shaving the hairs, or washing the hairs daily and scraping the nodules by hand. It can be cured by shaving the hairs and then using some antifungal agents (e.g., 0.05% mercuric chloride, 6% salicylic acid, 12% benzoic acid, 3% sulfur, or 2% formaldehyde solution). The hair can also be washed with a solution containing ketoconazole and selenium disulfide. Topical treatment of palmar melanosis is often effective. Imidazole cream is particularly effective, applied externally 2 to 3 times a day for 2 weeks. Miconazole and clotrimazole creams are effective in the treatment of parapodial and plantar lesions. Miconazole is effective in the treatment of foot lesions. Keratolytic agents (such as 10% sulfur cream, 6% salicylic acid, 12% benzoic acid ointment or tincture) are often effective in the treatment of this disease. 2.Systemic treatment Suitable for systemic damage, surgery can not be removed cases. Most of the antifungal drugs are not sensitive, poor efficacy, the need for long-term, large quantities of medication. Infection caused by vial mold, flucytosine, fluconazole and amphotericin B is more effective. Trichoderma infections are only sensitive to flucytosine, which can be combined with amphotericin B. Recently, itraconazole and terbinafine have also been used in the treatment of this disease, but experience is still needed. (ii) Prognosis Systemic dark mycosis fungoides has a poor prognosis and often leads to death.
