acral fibrokeratoma
Introduction
Introduction to acral keratinoma Acromion keratoma, also known as acquired fibroma (acquired fibrokeratomaoffinger/toe) is a disease caused by hyperkeratosis of the epidermis, which is more common in male adults. Occurs in the vicinity of the joint between the fingers. The clinical manifestation is a solid, single-shot round or elongated protrusion. Surgical resection is the main treatment. basic knowledge Sickness ratio: 0.1% Susceptible people: no specific population Mode of infection: non-infectious Complications: internal injuries and fever
Cause
The cause of acral keratosis
Cause:
Histopathology showed that the epidermis of the tumor was significantly hyperkeratotic, the acanthosis was thick, the epidermis was widened and branched; the center of the tumor was intertwined, and the coarse collagen fibers were arranged vertically, surrounded by capillaries and reticular fibers.
Prevention
Limb fiber keratoma prevention
The disease is mainly related to local long-term compression and frictional stimulation, and may also be caused by local trauma and other localized tissue irritative degeneration and hyperplasia. Early detection, early diagnosis and early treatment are of great significance for indirect prevention of this disease. Therefore, when there is itching or keratosis in the local skin, regular anti-infective treatment should be carried out. It can be rubbed with vitamin A acid ointment and 20% urea ointment. To reduce the incidence of complications.
Complication
Limb fibroma complication Complications, internal injuries, fever
There may be mild inflammatory cell infiltration around the blood vessels, and the elastic fibers are broken, resulting in a decrease in skin elasticity. Secondly, due to the obvious keratinization of the skin, the skin is often broken due to scratching, and the skin integrity is destroyed. Therefore, the skin may be infected by bacterial infection or fungal infection, usually secondary to low constitution, or long-term use of immunosuppressants and ash. Patients with fungal infections such as nails, such as concurrent bacterial infections, may have symptoms such as fever, swelling of the skin, ulceration, and purulent secretion. Severe cases can lead to sepsis, which should be brought to the attention of clinicians.
Symptom
Symptoms of acral keratosis common symptoms Epidermal keratosis acne nodules wrist swelling and palm flexion...
1. The area of the hair is near the joint of the toe, and occasionally in the palm of the hand.
2. Clinical Symptoms A single round solid protrusion, long or dome-shaped, smooth surface, pink, with short pedicles, varying degrees of keratinization on the surface.
Examine
Examination of acral keratinoma
Histopathology: consists of densely arranged glass-like collagen bundles and varying amounts of fibroblasts. A small number of thin-walled blood vessels are visible. The blood vessels and collagen fibers are often arranged perpendicularly to the upper epidermis, and the epidermis is usually hyperkeratotic and The acanthosis is thick.
Diagnosis
Diagnosis and diagnosis of acral keratoma
According to the location of the disease and the characteristics of the lesion, the disease is generally not difficult to diagnose.
Differential diagnosis
1. Residual multi-finger (toe) exists at birth, located at the base of the fifth finger, often bilateral, and many nerve bundles are visible in the tissue image.
2. Sometimes it needs to be differentiated from the skin angle, the phalanx pad, the baby finger (toe) fibroids.
