Genetic (30%):

The disease belongs to a rare autosomal dominant genetic disease, which can be associated with a variety of hereditary types, and is related to various factors such as environmental factors and autoimmune factors.

pathology

The pathogenesis is still not clear. For a rare autosomal dominant inheritance. Histopathological examination: the basal layer of pigment particles increased, the hypopigmentation area was less, and the phagocytic cells in the dermis increased.

Diagnosis and differentiation of symmetry acral pigmentation in soil and fertilizer

diagnosis

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.

Differential diagnosis

1. Secondary pigmentation abnormalities after frostbite are caused by repeated inflammation, leukoplakia is more prominent than dark spots, no freckles-like rash on the face, no genetic characteristics.

2. Coloring dry skin disease In addition to pigmentation changes, there are dry skin, atrophy, telangiectasia and skin flushing.

3. Reticulated acral pigmentation Freckle-like pigmentation spots on the dorsal side of the extremities are particularly obvious and dense in the lateral part of the iliac crest. The pigmented spots are slightly concave compared with normal skin, but consistent with the sulcus, no pigmentation spots, and distribution. More extensive.
