Invasive micropapillary carcinoma is a rare variant of invasive ductal carcinoma of the breast. This variant has been described as clinically aggressive due to its high frequency of lymphovascular invasion, axillary nodal metastases, and a greater degree of loco-regional recurrence. Invasive micropapillary carcinoma can have a variety of imaging presentations, typically presenting as an irregular mass. This case report describes a unique presentation of invasive micropapillary carcinoma and illustrates the propensity of invasive micropapillary carcinoma to secrete fluid and have a lack of regional lymphadenopathy. The challenges of the accompanying diagnostic imaging-work up are discussed.
浸润性微乳头状癌是乳腺浸润性导管癌的一种罕见变异型。由于其淋巴管侵犯、腋窝淋巴结转移的高发生率以及更高程度的局部区域复发，这种变异型被描述为具有临床侵袭性。浸润性微乳头状癌可有多种影像学表现，典型表现为不规则肿块。本病例报告描述了浸润性微乳头状癌的一种独特表现，并说明了浸润性微乳头状癌分泌液体及缺乏区域淋巴结肿大的倾向。同时还讨论了伴随的诊断性影像学检查的挑战。
