在观察皮下结节或皮下硬结性病变的组织标本时,必须首先判定原发病变是在小叶间质还是在脂肪细胞团中.叶间结缔组织的炎症和真皮看到的炎症具有相同的过程,即皮肤脂膜炎(dermopanniculitis),临床表现为结节性红斑;而原发于脂肪细胞团中的炎症,则以引起脂肪细胞破溃为特征,在修复机制中,出现脂肪吞噬细胞,发生脂肪肉芽肿. When looking at tissue samples of subcutaneous nodules or subcutaneous indurative lesions, one must first determine whether the primary lesion is in the interlobular mesenchyme or in the adipose mass. The inflammation of the connective tissue between the leaves and the dermis sees the same process, Namely dermopanniculitis, which is clinically characterized as nodular erythema. Inflammation in primary adipose tissue mass is characterized by the rupture of fat cells. In the repair mechanism, fat phagocytosis occurs and fat is produced Granuloma.
