Fibroepithelial Lesions of the Breast - Image 1

Fibroepithelial Lesions of the Breast

Fibroepithelial breast lesions include common benign fibroadenomas in younger women and phyllodes tumors in older women, which may be cancerous. Because these lesions often look similar, careful imaging and pathology correlation is needed. Fibroadenomas are often observed, while phyllodes tumors usually require surgery.

Objectives

Upon completion of this course, students will:

  1. state the estimated occurrence of FELs in women
  2. choose the most common benign breast tumor in women especially under the age of 30
  3. recall the estimated incidence of FAs in symptomatic patients presenting to breast clinics
  4. list the patient population typically affected by juvenile and simple FAs
  5. state the most common benign breast neoplasm in young women
  6. recall the age in which complex FAs typically occur in women
  7. list the complex characterizations of FAs
  8. choose the menopausal stage in which myxoid FAs are more common
  9. define the Carney complex
  10. categorize the terms cellular, giant, and juvenile as they relate to FAs
  11. list the characteristics of cellular FAs at histopathologic analysis
  12. state the reported incidence of tubular adenomas among benign breast lesions
  13. explian when lactational adenomas occur
  14. describe the appearance of FAs at mammography
  15. describe the appearance of FAs at ultrasound
  16. list the characteristics of FAs at MRI
  17. know the percentage of FAs that have the characteristic non-enhancing internal septa at MRI
  18. describe the suspicious features that can be used to favor a diagnosis of mucinous carcinoma over myxoid FA
  19. choose the percent of PTs that account for all breast neoplasms
  20. list the malignant heterologous elements that PTs may contain
  21. choose the organization that no longer advocates for routine excision of some concordant lesions with atypia
  22. list the factors that radiologist should report on the pathology submission of FA specimens
  23. list the histologic features on core biopsy that have been found to be helpful in predicting PTs on excision
  24. state the standard of care for PTs
