原发性红斑肢痛症的组织病理学表现无特异性:特殊研究显示小神经纤维密度降低

摘要

The histopathology of primary erythromelalgia has been poorly characterized. A total of 33 skin biopsy specimens from 29 patients with a diagnosis of primary erythromelalgia were reexamined. Histopathologic findings were nonspecific. Vascular thrombi were not identified. A relative decrease in small nerve fiber density was noted in specimens from 13 of 16 patients.
