腋下副乳腺肿瘤超声表现特征

目的探讨腋下副乳腺肿瘤超声声像图特征。 方法回顾性分析2007年1月至2015年3月首都医科大学附属北京同仁医院经病理证实的5例腋下副乳腺肿瘤患者超声声像图特点。5例腋下副乳腺肿瘤中，3例伴胀痛，2例无胀痛。1例哺乳期有溢液。病理证实4例为副乳纤维腺瘤，1例为副乳癌。 结果超声声像图显示5个肿块均为低回声，内部回声均匀。4个副乳纤维腺瘤为椭圆形，边界清晰，血流信号呈少量或中量血流。1个副乳癌形态不规则，边界欠清，血流信号丰富。超声声像图显示3个纤维腺瘤周围见类乳腺腺体回声，1个纤维腺瘤及1个副乳癌周围未见类乳腺腺体回声。 结论腋下肿瘤周围类乳腺腺体回声及典型临床症状有助于副乳腺肿瘤的诊断。

Sonographic features of tumor in ectopic axillary breast tissue

ObjectiveTo observe the sonographic features of tumor developed in ectopic axillary breast tissue. MethodsThe sonographic features of five patients with tumor developed in ectopic axillary breast tissue confirmed by histopathology in Beijing Tongren Hospital, Capital Medical University from January 2007 to March 2015 were retrospectively reviewed. Among five patients with tumor originated from ectopic axillary breast tissue, 3 had regional swelling and tenderness, 2 presented without pain. There was scant secretion from one tumor during lactation. There were 4 fibroadenomas and 1 carcinoma arising from ectopic axillary breast tissue confirmed by histopathology. ResultsThe sonographic appearance of the five masses was homogeneous and hypoechoic. Four fibroadenomas arising from ectopic axillary breast tissue were oval-shaped, well-defined masses with mild or moderate vascularity on sonograms. One carcinoma arising from ectopic axillary breast tissue was an irregular, ill-defined mass with abundant vascularity. Ultrasonography showed that the breast-like tissue surrounded 3 fibroadenoma. This feature was not founded in 1 fibroadenoma and 1 carcinoma. ConclusionThe breast-like tissue surrounding axillary mass and typical symptom are useful to the diagnosis of tumor developed in ectopic breast tissue.
