The age of onset ranged from 36 to 76 years old, with a predilection between 40 to 69 years old, especially in the 50 to 59 age group, with an average age of onset of 50 years.

Among them, classical type is the most representative. This article is all classical. There are three classical types: 1. Erythema or eczema, also known as early polymorphic rash. 2. Flat infiltration or moss-like infiltration. Phases 1 and 2 are collectively referred to as pregranuloma, and only the first phase is referred to as pregranuloma. The authors divide the treatment according to the latter. 3. Granulation or tumor formation. In this article, we did not see the first phase in 17 cases, 3 cases of flat infiltration period, from the flat infiltration period
