As with papillary carcinomas in general, it tends to occur in postmenopausal women.
Pathologically, intracystic papillary carcinomas may show four cellular patterns:
- compact columnar epithelial
- stratified spindle cell
- transitional cell form resembling urothelium
The combination of two or more of these patterns may also be seen.
Some report value in measuring CEA levels in the aspirated cyst fluid 3.
On mammography, an intracystic papillary carcinoma is often seen as a round or oval circumscribed mass, most frequently in the retroareolar region.
The usual ultrasound appearance is a cystic mass, with or without septations, with solid papillary masses projecting into the cyst lumen.
Treatment and prognosis
A segmental mastectomy is usually performed, and axillary lymph node sampling (axillary lymph node dissection or sentinel lymph node mapping) is suggested in patients in whom invasion is likely.
Intracystic papillary carcinoma has a slow growth rate and an excellent prognosis with 10-year survival rates approaching 100% 1,2.
