纤维组织细胞瘤由软组织的不同种类的肿瘤所组成,可能起源于组织细胞。O′Brien & Stout(1964)曾描述过此种肿瘤的恶性类型。纤维组织细胞瘤发生于软组织的不同部位,但以四肢最常见;而头颈部则属罕见。1977年,Blitzer等复习35例头颈部不同部位的纤维组织细胞瘤,其中仅有6例位于鼻窦,2例起源于筛窦,4例起源于上颌窦。本文报告一例上颌窦恶性纤维组织细胞瘤,病变已侵及上颌骨和颧骨。该病例进行了手术根治,继以放疗。经过一年随访,未见局部复发或转移。
Fibrous tissue tumors are composed of different types of tumors in soft tissues and may originate from tissue cells. O’Brien & Stout (1964) has described the malignant type of this type of tumor. Fibrous histiocytoma occurs in different parts of the soft tissue, but is most common in the limbs; the head and neck are rare. In 1977, Blitzer et al. reviewed 35 cases of fibrous histiocytoma in different parts of the head and neck. Only 6 of them were located in the sinuses, 2 of them originated in the ethmoid sinuses, and 4 of them originated in the maxillary sinus. This article reports one case of malignant fibrous histiocytoma of the maxillary sinus. The lesion has invaded the maxilla and tibia. The case underwent radical surgery followed by radiotherapy. After one year of follow-up, no local recurrence or metastasis was found.
