Spindle cell lipoma

Introduction to spindle cell lipoma Spindle celllipoma is a special type of lipoma, mainly found in male elderly (40 to 70 years old). It accounts for 1.5% of the occurrence of lipoma. basic knowledge The proportion of illness: 0.003%-0.009% Susceptible people: no special people Mode of infection: non-infectious complication:

The cause of spindle cell lipoma

(1) Causes of the disease

The cause is still unknown.

(two) pathogenesis

The pathogenesis is still unclear.

Spindle cell lipoma 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.

Spindle cell lipoma complications Complication

There are generally no other complications.

Spindle cell lipoma symptoms Common symptoms Slow growth

Clinically, it is often characterized by a slow-growing, painless mass. In general, the tumors are mostly single nodules with clear boundaries or envelopes. The diameter is 1 to 13 cm, usually less than 5 cm. The cut surface is yellow or grayish yellow, with grayish-white rubber-like areas, which occur in the back, the part, and the pole. Individuals can occur on the face, in the skin or under the skin, and grow slowly.

Examination of spindle cell lipoma

Histopathology: The tumor is encapsulated by a capsule, with or without a capsule, and invades the surrounding muscle. The tumor consists of mature adipocytes and uniform spindle cells, which are present in the mucinous matrix and the thick collagen fiber bundle, and the spindle cells are small. , with a single nucleus, nuclear prolongation to bipolar, CD34 staining positive, often along the collagen bundle, or in the form of an umbrella distributed between the fat cells, usually, the two cells are roughly the same number, mixed together or one each At the site, the whole tumor tissue contains many mast cells, which is a unique point of this tumor. There are not many tumor vessels in the tumor. Both spindle cell lipoma and pleomorphic lipoma show the aberration of nuclear chromosome 16q.

Diagnosis and diagnosis of spindle cell lipoma

diagnosis

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

Differential diagnosis

Fibrolipoma

Only fibrous tissue hyperplasia, no bundled spindle cells, no obvious mucinous interstitial increase.

2. Fibrosarcoma

No fat cells.
