Desmoid tumor of the breast is a rare benign entity that usually is mistaken for carcinoma clinically and radiologically. We report two cases of desmoid tumor of the breast detected by mammography screening using digital breast tomosynthesis (DBT). The larger tumor was detected at both full-field digital mammography (FFDM) and DBT. The smaller desmoid tumor, however, was identified only at tomosynthesis. Mammographic and ultrasonographic findings at diagnostic work-up were consistent with carcinoma of the breast. Preoperative needle biopsies could not conclusively diagnose the lesions. Both patients underwent excisional biopsy and histopathology revealed fibromatosis of the desmoid type.
乳腺硬纤维瘤是一种罕见的良性病变，在临床和影像学上通常被误诊为癌。我们报告两例通过数字乳腺断层合成（DBT）乳腺钼靶筛查发现的乳腺硬纤维瘤病例。较大的肿瘤在全视野数字乳腺钼靶（FFDM）和DBT检查中均被发现。然而，较小的硬纤维瘤仅在断层合成检查中被识别。诊断性检查时的乳腺钼靶和超声检查结果与乳腺癌一致。术前针吸活检未能明确诊断这些病变。两名患者均接受了切除活检，组织病理学显示为硬纤维瘤型纤维瘤病。
