Abstract

PURPOSE
Tubular adenoma (TA) is known as a rare lesion of the breast which is difficult to diagnosis preoperatively because of its rarity and similarity to fibroadenoma. Hence, our purpose is to suggest the characteristic sonographic features for its correct diagnosis.
MATERIALS AND METHODS
We retrospectively analyzed the clinical data and mammographic and sonographic findings. of seven patients(mean age, 23) who during theprevious five years had presented at our hospital with pathologically-proven tubular adenomas.
RESULTS
TA was misdiagnosed as fibroadenoma, since on physical examination of these young females, the lesions presented apalpable, non-tender mass. Mammographically, they showed a well defined mass similar to fibroadenoma. however, Sonographic findings were characteristic of TA and compared to fibroadenoma, showed a well demarcated and smooth bordered mass with transverse long axis, posterior enhancement and homogeneous lower internal echogenecity. Nocase showed lateral wall refractive shadowing.
CONCLUSION
In young females, the clinical and mammographic findings of TA are similar to those of fibroadenoma. However, sonographic findings of TA can, be helpful in the differential diagnosis of this entity and fibroadenoma.
