Abstract

Histiocytic sarcoma (HS) is an extremely rare and aggressive malignant neoplasm of hematopoietic origin that shows morphologic and immunophenotypic evidence of histiocytic differentiation. In approximately 25% of the cases, presumed transdifferentiation of a preexisting hematolymphoid disorder can be demonstrated. Various extranodal sites, particularly the gastrointestinal tract, soft tissue, skin, and spleen, can be involved. Enhanced CT and FDG PET/CT findings of extranodal histiocytic sarcoma have been barely reported. We present a case with extranodal HS originating in the small intestine after gastric large B-cell lymphoma, mistaken for prostate cancer metastasis in a 76-year-old man.

摘要

组织细胞肉瘤(HS)是一种极为罕见且具有侵袭性的造血源性恶性肿瘤,其具有组织细胞分化的形态学和免疫表型证据。在大约25%的病例中,可以证实存在先前血液淋巴系统疾病的假定转分化。各种结外部位均可受累,尤其是胃肠道、软组织、皮肤和脾脏。关于结外组织细胞肉瘤的增强CT和FDG PET/CT表现鲜有报道。我们报告一例76岁男性患者,其在胃大B细胞淋巴瘤后发生起源于小肠的结外HS,最初被误诊为前列腺癌转移。
