本文报道7例石英结晶所引起假性纤维性组织细胞瘤。年龄22～71岁,其中6例在40岁以上。男4例,女3例。5例为无痛性肿块,1例痛疼明显,1例为偶然发现。4例肿块位于鼠蹊部,3例位于腹壁。其中5例曾分别在10～41年前于发病部位注射过含硅的药物。(4例为治疗疝用硬化剂,1例注射过狂犬疫苗。)另一例病变发生于手术疤痕附近,还有一例致病原因不明。此7例患者均行手术治疗,除两例失访外无一例复发,尽管一例行不完全切除,病变一直稳定不变。肉眼下此7例典型病变均呈灰黄色,外界不甚清楚,直径1～7cm不等,被密集纤维组织包裹,切面硬韧。显微镜下7例病理表现非常相似,由大量组织细
This article reports seven cases of quartz crystallization caused by pseudo-fibrous histiocytoma. Ages 22 to 71 years old, 6 of whom are over 40 years old. There were 4 males and 3 females. Five cases were painless masses, one case had pain and one case was found by chance. Four patients were located in the groin and 3 were located in the abdominal wall. Among them, 5 cases had been injected with silicon-containing drugs at the site of onset 10 to 41 years ago. (4 patients were treated with sclerotherapy and 1 patient was injected with rabies vaccine.) Another lesion occurred near the surgical scar, and one case of the cause was unknown. All 7 patients underwent surgical treatment. There was no recurrence except for two cases of loss of follow-up. Although one case was incompletely removed, the lesion remained stable. Under the naked eye, these 7 typical lesions were gray-yellow, and the outside world was not very clear. The diameter ranged from 1 to 7 cm and was surrounded by dense fibrous tissue. The cut surface was hard and tough. The pathological appearance of the 7 cases under the microscope was very similar, with a lot of tissue fine
