Ito mole
Introduction
Introduction to Ito Ito is a pigmented lesion that occurs in the distribution of the posterior supraclavicular and lateral cutaneous nerves of the shoulder and neck, the supraclavicular region and the upper arm. It is also known as the acromion deltoid. Ito often occurs in the trunk and limbs, and is common in the scapula, supraclavicular and deltoid areas. Many people are very concerned about the treatment of Ito, which was first reported by Ito in 1954, so it was named "Itosnevus". Ito is a pigmented lesion that occurs in the distribution of the posterior supraclavicular and lateral cutaneous nerves of the shoulder and neck, the supraclavicular region and the upper arm. It is also known as the acromion deltoid. basic knowledge Sickness ratio: 0.05% Susceptible people: no special people Mode of infection: non-infectious Complications: sepsis
Cause
Ito's cause
(1) Causes of the disease
The distribution of melanocytes in the skin is abnormal.
(two) pathogenesis
Microscopically, the melanocytes are located in the middle of the dermis, which may involve the upper part of the dermis or the subcutaneous tissue. The number of melanocytes is more, and there are more bulges in the lesions. The cell bodies are elongated and fusiform, scattered between the dermal collagen fibers. Melanocytes are seen in a few lesions.
Prevention
Ito prevention
Prevention: There is no effective preventive measure for this disease. Pay attention to health, do a good job of safety protection, reduce and avoid the irritating and accidental damage of adverse factors, can play a certain preventive role. In addition, early detection, early diagnosis and early treatment are also the key to the prevention and treatment of this disease. In case of onset, active treatment should be actively treated to prevent complications.
Complication
Ito complications Complications sepsis
The disease can be progressively enlarged, and the surface of the skin can be broken, so it is easy to be infected concurrently. Because the skin integrity is destroyed, it may cause skin bacterial infection or fungal infection due to scratching, usually secondary to low constitution, or Long-term use of immunosuppressive agents and fungal infections such as onychomycosis, such as concurrent bacterial infections may have fever, skin swelling, ulceration and purulent secretion. Severe cases can lead to sepsis, which should be brought to the attention of clinicians.
Symptom
Ito symptoms common symptoms pigmented spotted light brown spots
In the shoulder and neck, the upper clavicle area and the upper arm, the skin is light blue, grayish blue, light brown, dark brown or blue-brown rash or patch, mottled, generally the central color of the patch is dark, the edge is light, or the center For patches, the edges are spots, or the entire lesion is dense and dense, and the boundaries are not clear. Occasionally, some areas of the lesion may be slightly raised or have blue-black bumps of miliary size to mung bean size.
Examine
Ito's inspection
Routine skin examination: Light blue, grayish blue, light brown, dark brown or blue-brown rash or patch on the skin of the shoulder and neck, upper clavicle and upper arm, showing a mottled shape.
Diagnosis
Ito Diagnostic Identification
diagnosis
According to clinical manifestations, it is not difficult to diagnose.
Differential diagnosis
Different from the following diseases:
1. Mongolian plaque: It can be self-resolved within a few years at birth, and any part of the body can occur in the lesion.
2. Milk coffee spot: It is the skin manifestation of neurofibromatosis. It is a multi-colored and deep pigmented plaque on the surface of the skin. It is yellowish brown and varies in size.
