Oily granuloma

Introduction to oily granuloma Oilgranuloma belongs to the category of foreign body granuloma. It has been named oleogranuloma, paraffinoma. Often due to the injection of oil or insoluble lipid liquid, tissue is a special type of reaction to oil and fat foreign bodies, most of which form nodules or plaques, and the symptoms are mild or absent. basic knowledge The proportion of sickness: 0.003%-0.006% Susceptible people: no special people Mode of infection: non-infectious Complications: swelling

Causes of oily granuloma

(1) Causes of the disease

Due to the correction of human cosmetic defects, local injection of liquid paraffin oil or cod liver oil, vegetable oil (olive oil), for the purpose of Tulong milk or repairing some other collapsed deformities (such as saddle nose), and injecting oil, not absorbed by the body tissue, forming a Foreign body, which causes body tissue reaction, eventually mechanized or tissue necrosis, calcium deposition, formation of localized granuloma-like hyperplasia, late, because silicone substances are widely introduced into the body for cosmetic filling, so, due to injection of oil The resulting tissue response is rare.

(two) pathogenesis

Infused with oil, not absorbed by the body tissue, forming a foreign body, causing the body tissue reaction, eventually mechanized or tissue necrosis, calcium deposition, forming a localized granuloma-like hyperplasia.

Oil granuloma prevention

There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Oil granulomatous complications Complications swelling

Due to the formation of granuloma, the disease can form fibrous connective tissue after mechanization, and further develops to form scar tissue, which was originally implanted with liquid oil to achieve a cosmetic effect. However, due to the formation of granuloma leading to scar tissue, it can cause the replication of the mucosa, causing changes in tissue morphology and swelling.

Symptoms of oily granuloma Common symptoms Tensile inflammatory cells infiltrating nodular granuloma Subcutaneous fat necrosis

Frequent invasive swelling in the injection site, or subcutaneous induration or plaque, the epidermis may be normal or yellowish, reddish, and the mass is mostly round or irregular, to damage the presence of different depths, its activity Degree can be different, or fixed, or movable, occasionally collapse to the surface, forming a difficult ulcer, the site is often in the injection site, such as facial beauty, breast augmentation, or oil injection site, common hip, stock , abdominal, etc., or withered hemangioma, can be around the anus or tumor tissue, as for work accidents, oil pressure into the skin, can cause red nodules or plaques in the hands, local tissue swelling or subcutaneous fat necrosis, It is also an oily granuloma hyperplasia. The latter is not only dark purple, but also has local swelling. It has more symptoms. It can be nervous and oppressive in the early stage. After a long time, it can reach several years or decades, and tissue hyperplasia or necrosis occurs. Local pain can be gradually aggravated, and inflammatory lobular infiltration of fat lobule, fat cell necrosis, lipocytic granuloma and foreign body granuloma reaction, forming large oil droplets in the tissue.

Oil granuloma examination

Histopathology: It is of great significance for the diagnosis of this disease. In addition to not absorbing oil and fat, it looks like an "onion-like" cyst tissue, forming a majority of unequal eight-shaped, or round, or irregular cavities. Connective tissue and inflammatory infiltration of lymphocytes, plasma cells, foamy macrophages, and reactions caused by vegetable oils, which may contain fine oil particles.

Diagnosis and identification of oily granuloma

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.

According to the history of injection and the characteristics of skin lesions, it is not difficult to diagnose, and its unique histopathological changes can be distinguished from fibrosis, lipoma, and hard erythema.
