Histopathologically, the lesion showed an almost normal epidermis and a granulomatous inflammation composed of epithelioid cells, multinucleated giant cells, and lymphocytes in the superficial and middle dermis. Alcian blue staining revealed mucin deposition in the granulomas. There was some degeneration of collagen fibers. Perineural inflammatory infiltrates and thrombosis were observed in the deep dermis and subcutaneous tissue. At 1 week after biopsy, the lesions had almost disappeared without any treatment.
