Papular vascular hyperplasia

Introduction to papular angiogenesis Papularangioplasia was first proposed by Wilson Jones and Marks in 1970. Two cases of this disease have been published before, one case was reported by Winer and Levin with Kaposi sarcoma, and one case was atypical by Peterson et al. Suppurative granuloma report. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious complication:

Cause of papular angiogenesis

The pathogenesis is still unclear. Atypical vascular hyperplasia can be seen in the dermis. The small capillary lumen is lined with columnar endothelial cells that are large and protrude into the lumen. They can be arranged in a double layer, and the endothelial cells are sometimes free in the lumen. There are a large number of cells like endothelial cells or fibroblast-like cells in the interstitial, and many cells are atypical, nuclear chromatin is abundant, and occasionally multinucleated. Red blood cell overflow can be seen.

Prevention of papular vascular proliferation

There are no effective preventive measures 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.

Papular vascular hyperplasia complications Complication

The papules caused by the limited edema of the epidermis may be accompanied by eczema, contact dermatitis, and the like. Clinically, it is characteristic because various cells infiltrate the papules caused by the epidermis or dermis.

Papular vascular hyperplasia symptoms common symptoms papular vascular hyperplasia

For multiple soft, pale purple red pimples, the diameter is only a few millimeters, the number is 2 to 30, which is good for the face, which can naturally subside.

Examination of papular angiogenesis

Histopathology: The dermis is seen in atypical vascular hyperplasia, a small capillary lumen, which is composed of many large and prominent columnar endothelial cells arranged in a layer. Even the double layer is visible. The interstitial interstitial has many nuclei deeply stained, which is atypical. Occasionally, multinucleated cells, red blood cells extravasation can be seen in the stroma.

Diagnosis and diagnosis of papular angiogenesis

The disease occurs mostly in the face and trunk of the elderly. The damage is lavender vascular papules, round or elliptical, with a diameter of 1 to 3 mm, soft and fading, and the number varies from 2 to 30. It needs to be differentiated from pyogenic granuloma, Kaposi sarcoma and angiosarcoma. If there is not enough clinical data, it is difficult to rule out Kaposi sarcoma and angiosarcoma.

Purulent granuloma, also known as telangiectasia granuloma, is a polypoid lesion formed by the proliferation of skin and mucous membranes and venous lobular hyperplasia, often caused by minor injuries. A benign lesion of the oral mucosa for organizing a reactive lesion of trauma and infection.
