The authors report two cases of sclerosing lipogranuloma of the scalp diagnosed postmortem. The first was suspected to have acquired the lipid material from a grease gun injury to the scalp, while the second had received injections of an unidentified lipid for treatment of baldness. In each, the resultant sclerosing lipogranuloma extended laterally beneath the scalp from the vertex of the skull. The histologic reaction was round to oval cystic spaces within a dense collagenous stroma typical of the "swiss cheese" pattern of sclerosing lipogranuloma. Punctate, ringlike, or globoid densities were seen on roentgenograms of a 5-mm-thick transmural section of scalp in the first case.
作者报告了两例头皮硬化性脂肪肉芽肿病例，均为死后诊断。第一例疑似因头皮被油脂枪损伤而获得脂质物质，第二例曾接受不明脂质注射以治疗秃发。在每例中，所形成的硬化性脂肪肉芽肿均从颅骨顶点向头皮下方横向扩展。组织学反应为在致密胶原基质内出现圆形至椭圆形囊腔，这是硬化性脂肪肉芽肿典型的“瑞士奶酪”样模式。在第一例中，对5毫米厚的头皮全层切片进行X线检查时可见点状、环状或球状密度影。
