Microglandular Adenosis of the Breast

Clinical

Age range 28-82 years
- Mean about 50 years
May be a palpable mass or an incidental finding
No metastases reported
May recur
- Very rare aggressive local recurrence
Carcinoma may be associated with microglandular adenosis
- Conservation of immunophenotype and apparent transitional atypical cases support the possibility that microglandular adenosis is a precursor of carcinoma
- Incidence is unknown but reported as high as 27%
- Suggests that complete resection is indicated
