Most AMEs appear to represent variants of intraductal papilloma
. (3) The differentiation of papilloma with prominent myoepithelial cells from AMEs can be made based on architecture, pattern, and degree of myoepithelial proliferation.

are generally solitary and located in the subareolar region in the major and lactiferous ducts, hence the derivation of the term central/solitary papilloma.
The market for global intraductal papilloma
is constrained by the lack of awareness, high cost of surgery, complications of the surgery, lack of focus on women health in the developing and poorer regions of the world etc.
Excision is indicated for intraductal papilloma
of the breast diagnosed on core needle biopsy.
Histological examination of a core biopsy revealed intraductal papilloma
, and although follow-up was recommended unfortunately it was not performed.
Diagnosis of breast cancer with mammography is established on the difference of density of lesion and surrounding tissue.20 In this study, among the lesions in grade 4A, there were 13 cases of benign lesions including two cases of adenoma, five cases of adenoma fibrosum, two cases of intraductal papilloma
, one case of mastitis, one case of breast phyllodes tumor, one case of hyperplasia of mammary glands and one case of granulomatous inflammation and seven cases of malignant lesions.
In the present study, fibrocystic disease is the predominant benign lesion comprising 39 cases (41%), followed by fibroadenoma 26 cases (28%), fibrocystic disease with columnar cell change 13 cases (14%), sclerosing adenosis 8 cases (8%), intraductal papilloma
5 cases (5%), apocrine adenoma 3 cases (3%), benign phyllodes 1 case (1%) (Figure 2).
Two cases of intraductal papilloma
were diagnosed on cytology.
is a benign growth within the ductal system and presents as bloody nipple discharge.
Of these 7 patients, 2 underwent excisional biopsies, demonstrating an invasive lobular carcinoma in 1, and an intraductal papilloma
in the other.
