Extraabdominal fibromatosis or desmoid tumor (DT) is a slow growing locally aggressive soft tissue tumor that can occur anywhere in the body. We report the aspiration biopsy cytology features of a case of DT of the right neck area in a 35-year-old man who had a long standing history of tumoral calcinosis. The aspirate was interpreted as "benign spindle cell lesion" and confirmed as DT on histologic examination of the resected mass. We discuss the possible differential diagnoses of other benign or malignant lesions on fine-needle aspiration (FNA) biopsy and especially discuss the aspiration cytology features of DT compared with those of tumoral calcinosis. We also discuss the value of immunohistochemical markers that help in differentiating DT from other entities.
腹外纤维瘤病或韧带样瘤（DT）是一种生长缓慢、具有局部侵袭性的软组织肿瘤，可发生于身体的任何部位。我们报告了一例35岁男性右颈部区域DT的针吸活检细胞学特征，该患者有长期肿瘤性钙化病史。吸出物被诊断为“良性梭形细胞病变”，切除肿块的组织学检查证实为DT。我们讨论了细针穿刺（FNA）活检中其他良性或恶性病变的可能鉴别诊断，特别是将DT的针吸细胞学特征与肿瘤性钙化的特征进行了比较。我们还讨论了有助于将DT与其他实体区分开来的免疫组化标志物的价值。
