achromatic pigment disorder
Introduction
Introduction to leukochromic disorders Achromic pigmented insults (incontineticapigmentiachromians), also known as hypomelanosis of Ito, are more common in women than men, often sporadic. basic knowledge The proportion of illness: 0.015% Susceptible people: no special people Mode of infection: non-infectious Complications: pruritus, skin cancer
Cause
Causes of leukorrhagic pigment disorders
(1) Causes of the disease
The cause is unclear and may be an autosomal dominant hereditary disease.
(two) pathogenesis
The pathogenesis is still unclear.
Prevention
Achromic pigment disorder prevention
Early detection and early diagnosis and early treatment.
Complication
Achromic pigmentation disorder complications Complications pruritus skin cancer
The disease is mainly caused by hypopigmentation, which causes the skin to resist UV rays. After intense ultraviolet light, skin itching, blisters, skin peeling and other manifestations may occur. This is related to the weakening of the skin's ability to resist ultraviolet light. Severe cases can also induce skin cancer, the appearance of flaky ulcers of the skin, a progressive increase, often combined with infection caused by the secretion of a large number of purulent secretions.
Symptom
Symptoms of leukochrome disorders Common symptoms Pigmentation and hypopigmentation Skin atrophy and pigmentation
The pigmentation spots are splashed with water, and the lateral distribution is distributed on the trunk and limbs. The sweating function and capillary tension of the affected area are all reduced. The disease is often secondary to vesicular damage, and the lesion can be seen with depression or atrophy.
Examine
Colorless pigmentation disorder examination
Histopathology: The number of melanocytes in the lesion area is normal or decreased, the melanin content in the basal layer of the epidermis is reduced, and there is no melanocyte in the dermis.
Diagnosis
Diagnosis and differentiation of leukochrome disorders
According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
Should be identified with no pigmentation.
