Overview
Biopsy may be helpful in the diagnosis of Paget's disease of the breast. Findings on biopsy diagnostic of Paget's disease of the breast include presence of Paget cells, which are arranged in solid groups.[1]
Biopsy
- Biopsy may be helpful in the diagnosis of Paget's disease of the breast.
- Biopsy can be performed by shaving, punch or incisional techniques, the latter being the most appropriate one.[1]
- It is essential that the sample contains part of the lactiferous duct and if the areola is affected, it also needs to be represented in the sample to confirm the diagnosis.
- Often histological exams are inconclusive and more biopsies, or even surgical removal of the entire nipple may be required.
- The main histological characteristic is the presence of Paget cells, which are arranged in solid groups.
- On occasion, they form glandular arrangements outlining the basal epidermis and exhibit migration to the granular layer, similarly to melanocytes.
