Pleomorphic lipoma

Introduction to pleomorphic lipoma Pleomorphic lipoma (peomorphiclipoma) is rare, occurring in middle-aged men. Clinically similar to spindle cell lipoma, it occurs mostly in the shoulder and neck, with a diameter of 1 to 13 cm, slow growth, and a few recent accelerated growth. Although both pleomorphic lipoma and spindle cell lipoma show aberrations in nuclear chromosome 16q, the disease is still benign. basic knowledge The proportion of illness: 0.03% Susceptible people: no specific people Mode of infection: non-infectious Complications: ischemic necrosis

Cause of pleomorphic lipoma

(1) Causes of the disease

The cause is still unknown.

(two) pathogenesis

The pathogenesis is still unclear.

Polymorphic lipoma prevention

Pay attention to the law is to live, maintain a good attitude, avoid mood fluctuations to avoid depression, pay attention to decompression, etc. It is helpful; at the same time pay attention to diet reasonable, avoid smoking and drinking, avoid eating fat and greasy food, avoid psychological stimulation of food.

Polymorphic lipoma complications Complications ischemic necrosis

Polymorphic lipoma is a benign lesion, usually with few complications, mainly local skin lesions, partial friction or scratching, causing skin lesions, may be complicated by bacterial infection; local long-term stimulation, a few can lead to eczema changes Or with the occurrence of local eczema; some pedicles are smaller, and the larger apical lipoma may have pedicle torsion, leading to ischemic necrosis.

Symptoms of pleomorphic lipoma Common symptoms Slow growth and cold stimulation of skin lesions...

Clinically similar to spindle cell lipoma, it occurs mostly in the shoulder and neck, with a diameter of 1 to 13 cm, slow growth, and a few recent accelerated growth. Although both pleomorphic lipoma and spindle cell lipoma show aberrations in nuclear chromosome 16q, the disease is still benign.

Examination of pleomorphic lipoma

Currently there are no related content description.

Histopathology: The tumor tissue is clearly defined, and the tumor cells are highly pleomorphic. Although mature fatty cell regions are found, most fat cells vary in size. About half of the tumors have fat cells or vacuolated cells, which are present in a small amount of mucus. Among the interstitial, there are a large number of dense, staggered collagen bundles. There may be multiple overlapping nuclei in the tumor cells, or arranged in petal-shaped giant cells. The chromosome division in the nucleus is rare and there is no necrotic tissue.

Diagnosis and diagnosis of pleomorphic lipoma

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

1. Liposar sarcoma: invasive growth, more tumor cells, more atypical nucleus, and see atypical mitotic figures, multiple vacuolarized fat cells, no thickened collagen fiber bundles, rare petal-shaped giant cell.

2. Spindle cell lipoma: spindle cells account for the majority, in the pleomorphic lipoma is small focal.
