Skin osteoma

Introduction to cutaneous osteoma Osteomacutis may be a tumor that originates from pluripotent mesenchymal tissue. The tumor may be single or multiple, with a diameter of 0.1 to 5 cm, a clear boundary and a hard texture. basic knowledge The proportion of illness: the incidence rate is 0.002% - 0.004% Susceptible people: no special people Mode of infection: non-infectious complication:

Cause of cutaneous osteoma

(1) Causes of the disease

The cause is still unknown.

(two) pathophysiology

In the osteoma of the dermis or subcutaneous tissue, irregular normal bone tissue regions are visible. In some cases, the Hastelloy tube is visible, and there is a typical plate-like structure around it. Osteoblasts and osteoclasts can be seen around the bone tissue area. The osteoblasts are single long, and the osteoclasts have several nuclei, similar to foreign giant cells. There is a distinct tissue reaction between the blood vessels and the cells around the bone tissue.

Skin osteoma prevention

Prevention of cutaneous osteoma should first focus on and improve those factors that are closely related to our lives, such as smoking cessation, proper diet, regular exercise, and weight loss. Appropriate exercise, enhance physical fitness and improve your disease resistance. Anyone who follows these simple and reasonable lifestyles can reduce their chances of developing cancer. Therefore, pay attention to personal and environmental hygiene, avoid drug abuse, and pay attention to personal protection when working in a harmful environment.

Dermal osteoma complications Complication

Osteosarcoma is the most benign of bone tissue tumors, with few malignant changes. Most of the patients are teenagers and youth. The skull and upper and lower jaws are intended to be good sites. Slow growth and less symptoms. When it protrudes into the cranial cavity, eyelids, nasal cavity and nasal discharge, it can cause compression symptoms. When it develops toward the surface of the skull, it can cause abnormalities in appearance. After the whole body is merged, the tumor stops growing on its own. Therefore, in addition to the more serious compression symptoms or excessive deformity must be surgically removed, do not have to consider treatment; but should continue to observe, due to occasional malignant changes in osteoma. The tumor should be surgically removed during treatment and include a small amount of normal bone around the tumor. Otherwise, the tumor can recur and even malignant.

Symptoms of cutaneous osteoma Common symptoms Local tenderness

The tumor can be single or multiple, and it occurs in the scalp, forehead, cheek and chin. The diameter is 0.1~5cm. It is spherical, the boundary is clear, the texture is hard, the surface is skin color or red, pigmentation, and it can be broken. Have pain or tenderness.

Clinical can be divided into 4 groups:

1 generalized osteoma, which occurs or occurs in adolescents when born;

2 single large osteoma, occurring in the skin and subcutaneous of the scalp or limb after birth;

3 single small osteosarcoma, occurring in adolescents, sometimes excreted bone fragments percutaneous;

4 face multiple miliary osteoma, seen in young women with lupus vulgaris or older women without acne.

Sometimes the nucleus is large and deeply stained, and it looks like malignant, but the clinical progress is benign and there is no metastasis.

Examination of cutaneous osteoma

Histopathology: Osteogenesis in the dermis or subcutaneous tissue, surrounded by osteoblasts and osteoclasts. The former has a single nucleus and a long original shape. The latter has multiple nuclei, foreign bodies like giant cells, and mild capillaries around the lesion. Hyperplasia and see inflammatory cells.

Diagnosis and differentiation of cutaneous osteoma

diagnosis

According to the specific clinical manifestations, medical history, examination for diagnosis.

Differential diagnosis

1. Calcium deposition in the skin is characterized by an amorphous structure, HE staining is dark blue, and no osteoblasts can be identified.

2. Secondary ossification of the skin is identified by histopathology.
