We report a case of a 76-year-old man presenting with a 12-month history of a solitary lesion on his scalp. The histopathology was consistent with a grade 2/3 osteosarcoma extending to the subcutis. Full-body imaging excluded any involvement of the underlying bony tissue or solid organ malignancy, thus a diagnosis of primary cutaneous osteosarcoma (PCO) was made. Given the exceedingly rare nature of PCO, we discuss the clinico-pathological features of this case and those previously reported in the literature.
我们报告了一例 76 岁男性患者，其头皮上有一处孤立性病变，病史长达 12 个月。组织病理学检查符合 2/3 级骨肉瘤，延伸至皮下组织。全身成像排除了任何潜在骨组织或实体器官恶性肿瘤的累及，因此诊断为原发性皮肤骨肉瘤（PCO）。鉴于 PCO 的罕见性质，我们讨论了该病例的临床病理特征以及文献中以前报道的特征。
