systemic idiopathic telangiectasia
Introduction
Introduction to systemic idiopathic telangiectasia Systemic idiopathic telangiectasia (generalizedidiopathictelangiectasia), an unexplained telangiectasia of the extremities and trunk. More common in women aged 40 to 50. The cause of the disease is still unknown. The lesions are usually distributed in the calf or along the nerve. They are usually lined up. They can also be expressed as small hemangiomas. There is no specific treatment. Oral antibiotics may be effective in some patients. basic knowledge The proportion of sickness: 0.2% - 0.35% Susceptible people: no specific population Mode of infection: non-infectious Complications: bleeding disorders
Cause
Causes of systemic idiopathic telangiectasia
Cause:
The cause of this disease is unknown.
Pathogenesis
The pathogenesis of this disease is still unclear.
Pathology: The dermal capillaries in the upper part of the dermis are dilated and congested. The wall of the dermis is composed only of endothelial cells, and the alkaline phosphatase activity is absent, indicating the venous part of the expanded capillary capillaries.
Prevention
Systemic idiopathic telangiectasia prevention
1. Strengthen care and nutrition to improve patient resistance and immunity.
2. Prevention of infection should pay attention to isolation and minimize contact with pathogens.
Complication
Systemic idiopathic telangiectasia complications Complications, bleeding disorders
1. Conjunctivitis: Conjunctivitis is a general term for the inflammatory reaction of conjunctival tissue in the external and internal factors. Although conjunctivitis itself is generally not severely affected by vision, it can cause vision damage when its inflammation affects the cornea or causes complications.
2. Oral ulcer: a superficial ulcer that occurs on the oral mucosa. It can range in size from rice to soy, round or oval, with a concave surface and congestive congestion. Ulcers are characterized by periodicity, recurrence and self-limiting, which occur in the lips, cheeks, and tongue. The etiology and pathogenesis are still unclear. The cause may be local trauma, mental stress, changes in food, drugs, hormone levels, and vitamin or trace element deficiency. Systemic diseases, genetics, immunity, and microorganisms may play an important role in their occurrence and development.
Symptom
Systemic idiopathic telangiectasia symptoms Common symptoms telangiectasia hyperemia
The disease is more common in women aged 40 to 50 years, the skin lesions first in the calf, and later extended to the thigh, abdomen and buttocks, the distribution may be systemic or unilateral, or limited to a certain part, or distributed along the nerve, Generally arranged in a line, it can also be expressed as small hemangioma, and some patients can invade the conjunctiva and oral mucosa.
Examine
Examination of systemic idiopathic telangiectasia
Currently there are no related content description.
Tissue biopsy dermal capillaries dilate, hyperemia, the wall is composed only of endothelial cells, alkaline phosphatase activity is absent.
Diagnosis
Diagnosis and differentiation of systemic idiopathic telangiectasia
According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
Need to distinguish from atypical hereditary hemorrhagic telangiectasia and telangiectasia with systemic diseases, hereditary hemorrhagic telangiectasia lesions are widely distributed, occur in the upper part of the body, symmetry, bleeding Features, telangiectasia associated with systemic disease contains active alkaline phosphatase in endothelial cells of the peripheral arterioles and capillary iliac arteries.
