Cutaneous granulomas are formed by the infiltration and proliferation of inflammatory cells, accompanied by capillary hyperplasia and fibroblast encapsulation. Skin granulomas include infectious granulomas and foreign body granulomas. Infectious granuloma is mostly due to bacterial, fungal, parasitic infections, such as dermatophyte infections, which can form chronic inflammation in the skin, with a large number of macrophages and lymphocytes infiltrating around the inflammation, and fibroblasts proliferating, accompanied by vascular hyperplasia. Long-term repeated action, the formation of skin granuloma. Foreign body granuloma is a foreign body left in the skin (such as wood splinters, sutures, etc.), macrophages and other inflammatory cells will encircle the foreign body, accompanied by fibroblasts, lymphocytes proliferation, the formation of a nodule, i.e., cutaneous granuloma. There are many reasons for the formation of dermatogranuloma, it is recommended to improve the relevant examinations in a timely manner to clarify the diagnosis, and standardized treatment under the guidance of a professional doctor.
