Abstract

• Purpose
  To evaluate pathologic findings of fibrocystic disease correlated with sonographic findings in the patients with solid lesion on ultrasonography.
• Materials and Methods
  Total 63 pathologically proven fibrocystic disease in 57 patients are retrospectively evaluated. On ultrasonography, the lesions were divided into solid and non-solid mass-like lesions. We analyzed the margin and echogenicity of solid mass-like lesions that were correlated with pathologic findings and also statistically analyzed Chi-square and Fisher's exact test.
• Results
  Ultrasonogram of fibrocystic disease showed solid mass-like lesion in 73% and non solid mass-like lesion in 27%. Among the solid lesions, well-defined margin revealed in 72%, ill-defined margin in 28% and hypoechoic in 59%, isoechoic 41%. On the pathologic analysis, the solid and the non-solid mass-like lesion showed respectively : fibrous stroma in 56.5% and 53%, fibroadenomatous change in 50% and 12%, mixed stroma in 41% and 35.3%, cystic change in 37% and 70.6%, ductectasia in 28% and 58.8%, lobular hyperplasia in 26% and 12%, ductal hyperplasia 13% and 5.9%, and adenosis in 8.7% and 0%. The solid lesions showed more fibroadenomatous change and the difference between there was statistically significant(p=0.008).
• Conclusion
  The solid mass-like lesion, which represented as a well-defined isoechoic benign mass on ultrasonogram was more common than as expected, and this was due to the fibroadenomaous change on histopathology.
