The aim of this review is to illustrate the mammographic and sonographic appearances of squamous metaplasia of the lactiferous ducts (SMOLD) and to discuss the disease processes of this uncommon breast disease, which shows a strong correlation with smoking. The most common mammographic appearance is of a retro-areolar asymmetrical density. Ultrasonography of the symptomatic breast typically shows a retro-areolar, predominately medial, ill-defined, hypoechoic lesion with either abscess or sinus/fistula formation. Duct dilatation and continuity with lactiferous ducts is commonly seen. Increased vascularity is occasionally seen on colour Doppler ultrasound. Pathology tissue confirmation is always required and this can be by histology of a core biopsy or excision specimen, or fine-needle aspiration (FNA) cytology. Occasionally smears of an associated abundant nipple or sinus discharge may be of value.
本文旨在阐述乳管鳞状上皮化生（SMOLD）的乳腺 X 线摄影和超声表现，并讨论这一不常见乳腺疾病的病变过程，该病与吸烟有很强的相关性。最常见的乳腺 X 线摄影表现为乳晕后不对称性密度。症状性乳房的超声检查通常显示乳晕后、主要为内侧、边界不清的低回声病变，伴有脓肿或窦道/瘘管形成。导管扩张并与输乳管相连是常见的。彩色多普勒超声偶尔可见血管增多。总是需要进行病理组织学确认，这可以通过核心活检或切除标本的组织学，或细针抽吸（FNA）细胞学来完成。偶尔，相关丰富的乳头或窦道分泌物的涂片可能具有价值。
