Overview
The definitive diagnosis of fibroadenoma is confirmed by an ultrasound guided biopsy. Characteristic findings for fibroadenoma on microscopic histopathological analysis can be found here.[1]
Other Diagnostic Studies
Aspiration Cytology
- The definitive diagnosis of fibroadenoma is confirmed by an ultrasound guided biopsy. Characteristic findings for fibroadenoma on microscopic histopathological analysis can be found here.[1]
- Indications for an ultrasound guided biopsy include:
- Rapidly enlarging mass
- Atypical findings on ultrasound
- A lesion greater than 2.5 cm in size, with no previous studies for comparison
- Patients preference
- The characteristic cytologic features of fibroadenomas include:[2]
- Clusters of spindle cells without inflammatory or fat cells. This is found in 96% of all fibroadenomas.
- Aggregates of cells with a papillary configuration resembling elk antler (antler horn clusters). Found in about 93%.
- Uniform cells with well-defined cytoplasm lying in rows and columns (honeycomb sheets). Found in about 95%
