Abstract：Objective To investigate the causes of misdiagnosis of minimal breast carcinoma ( MBC) by ultrasound. Methods We retrospectively reviewed the clinical and ultrasonic data of 90 cases of MBC which confirmed by pathology. Re-sults Among the 90 cases, 58 cases were diagnosed accurately, and 32 cases were misdiagnosed. Twenty cases were misdi-agnosed as having breast fibroadenoma, ten cases were misdiagnosed as having lobular hyperplasia, and two as having adenosis of the breast. The range of largest diameter of tumors was 0. 5-1. 0 cm in 55 cases, among whom, 37 were diagnosed correc-tively by ultrasound, and 18 were misdiagnosed, and there were significant differences of edges and microcalcification signs between the two groups(P<0. 05). There were 35 patients with tumor diameter less than or equal to 0. 5 cm, among whom, 21 were diagnosed correctively by ultrasound, and 14 were misdiagnosed, and there were significant differences of aspect ratio and nodule number between the two groups (P<0. 05). The tumor edges in patients with different tumor diameters (0. 5-1. 0 and ≤5 cm) showed significant difference (P<0. 05). Conclusion The nodules of MBC patients showing diameter of 0. 5-1. 0 cm, clear edges and no calcification in ultrasound may be easily misdiagnosed. Furthermore, multiple nodules with diam-eter less than or equal to 0. 5 cm and aspect ratio less than 1 were also easily misdiagnosed.
