Fine reticulate to patchy hyperpigmentation
Introduction
Introduction The pigmentation spots are finely meshed to patchy and initially reddish. After turning to grayish gray to dark brown, it is often found on the exposed parts of the cheeks, neck and back, especially around the eyelids and the ankles. It can be seen in congenital keratosis, in the upper part of the trunk, neck, shoulder, face, abdomen, etc. It can be seen that the fine fine mesh gray-brown pigmentation is velvety. At the same time, it can be seen that the skin is atrophied and the telangiectasia is very obvious, just like vascular atrophic cutaneous heterochromia. The facial skin is red and atrophy, and there may be irregular pigmentation. The skin of the hands and feet is widely atrophied and transparent, and there may be diffuse keratotic damage in the palms, ankles, knees and elbows. It is easy after skin trauma. Form a bullous. Patients can sometimes have changes in atrophic deformities of the skin, muscles, and hands and feet.
Cause
Cause
Can be seen in congenital keratosis, generally has three characteristics:
1 methyl malnutrition, can not form a deck.
2 oral, inter- or vaginal mucosa may have white thickening (white keratosis).
3 The skin may have extensive reticular pigmentation and discoloration areas of vascular atrophic cutaneous heterochromia, but is lighter.

Can be seen in congenital keratosis, visible in the upper part of the trunk, neck, shoulders, face, abdomen, etc., fine fine-grained gray-brown pigmentation, velvet-like feeling. At the same time, it can be seen that the skin is atrophied and the telangiectasia is very obvious, just like vascular atrophic cutaneous heterochromia. The facial skin is red and atrophy, and there may be irregular pigmentation. The skin of the hands and feet is widely atrophied and transparent, and there may be diffuse keratotic damage in the palms, ankles, knees and elbows. It is easy after skin trauma. Form a bullous. Patients can sometimes have changes in atrophic deformities of the skin, muscles, and hands and feet.
Diagnosis
Differential diagnosis
It should be differentiated from congenital cutaneous heterochromia and non-perspiration ectodermal dysplasia.
Dermatopathia pigmentosa reticularis (DPR) is a rare disease that is mainly characterized by reticular pigmentation, non-scarring alopecia and malnutrition.
