Background:
Both Paget's disease (PD) and nipple adenoma (NA) are rare lesions occurred on nipple and share some similarities in clinical manifestations, but there are have different pathological manifestations and imaging findings. This study analyzed the clinicopathological and imaging features of PD in nipple and NA to improve our knowledge about these two diseases and to provide guidance for clinical diagnosis and treatment.
Methods:
Retrospectively analyzed 99 female patients confirmed by surgery and pathology from January 2014 to December 2018. The features of imaging examination included 95 cases of breast ultrasound, 83 cases of breast X-ray and 24 cases of magnetic resonance imaging (MRI) were analyzed and compered the detection rate and diagnostic accuracy.
Results:
The 99 patients consisted of 76 patients with PD and 23 patients with NA. Despite the similarity of clinical manifestations between PD and NA, the pathological features of these diseases were completely different. Differences in various imaging manifestations were found to facilitate differential diagnosis. Breast X-ray and ultrasound can discover the nipple areola changes such as mass and calcification, but some cases still show negative. Breast MRI can clearly show the areola lesions of nipple PD and NA, accurately evaluate the degree and size of breast lesions, and help clinicians choose appropriate and personalized diagnosis and treatment methods.
Conclusions:
The combination of multiple breast imaging examinations (including X-ray, ultrasound, and MRI) can improve the diagnosis of PD and NA and play a guiding role in the options for clinical treatment.
