cavernous lymphangioma
Introduction
Introduction to cavernous lymphangioma Cavernous lymphangioma (cavernouslymphangioma) is a mass formed by the development of primitive lymphatic vessels. It is a congenital malformation, a hamartoma, and a borderline between tumor and deformity. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: pneumonia
Cause
Cause of cavernous lymphangioma
(1) Causes of the disease
When the mesoderm in the embryonic venous plexus forms a primitive lymphatic sac, a misconfiguration occurs, causing the primitive lymphatic sac to fail to communicate with the venous system, or fail to communicate with the lymphatic trunk, or a small amount of lymphatic sac in the lymphatic system. Separated, resulting in circulatory disorders of the lymphatic system.
(two) pathogenesis
The mesoderm gap in the embryonic venous plexus fuses to form a large primitive lymphatic sac, which drains into the central venous system, and then the lymphatic sac gradually degenerates or develops into a lymphatic system parallel to the vein, if the primitive lymphatic sac and lymphatic system are not In common, spongiform lymphangioma can occur. Most of lymphangioma and hemangiomas exist at birth. They are actually a congenital malformation, a hamartoma, and a borderline between tumor and deformity. .
Histopathology: It can be seen that the cavernous lymphangioma is a multi-atrial cystic cavity with a thick cyst wall, which is filled with lymph fluid and rich in connective tissue interstitial.
Prevention
Cavernous lymphangioma prevention
There is no effective preventive measure for this disease. Early detection and early treatment are the key to prevention.
Complication
Cavernous lymphangioma complications Complications pneumonia
1. Spongiform lymphangioma of the huge cheeks sometimes invades the mouth, tongue, and lower throat, causing difficulty in eating and speaking or causing difficulty in breathing or even suffocation.
2. Pneumonia, tongue, and cavernous cavernous lymphangioma can affect eating, causing food to be inhaled into the respiratory tract to produce lung infection.
Symptom
Symptoms of cavernous lymphangioma Common symptoms There is swelling and tenderness in the hyoid bone area, swelling of the lower lip, bulging, gingival swelling, giant tongue
Cavernous lymphangioma is located in the dermis or subcutaneous tissue, and occurs in the head and neck and lower limbs, especially in the lips, tongue, cheeks, etc. The lesions are unclear, soft and compressive, but do not change with body position, and the volume can be large. Can be small, large, local tissue obviously swelling and deformation, and affect the function, such as giant lips, giant tongue, etc., the surface of the tumor surface is normal, or light red, piercing can extract a light yellow transparent liquid.
Examine
Examination of cavernous lymphangioma
B-ultrasound, CT examination helps to confirm the diagnosis and understand the location and extent of the lesion.
Diagnosis
Diagnosis and diagnosis of cavernous lymphangioma
diagnosis
According to clinical features and auxiliary examinations, it is generally not difficult to diagnose.
Differential diagnosis
Cavernous lymphangioma needs to be differentiated from cavernous hemangioma. The former has a slightly firmer texture, and its compressibility and morphological changes with body position are not as obvious as hemangioma. Hemangiomas can sometimes be touched with venous stones. In the presence of lymphangioma, the surface of the lymphangioma is more normal, while the hemangioma is often seen with a blood-expanded blood vessel, resulting in a slight blue color in the part. The puncture examination shows that the color of the obtained liquid is different and can be clearly distinguished.
