The spectrum of breast diseases in Saudi Arab females: A 26 year pathological survey at Dhahran Health Center

Abstract

In an attempt to delineate the spectrum of breast diseases in Saudi Arab females, we carried out a retrospective study of all cases of breast biopsies and mastectomies accessioned in the files of surgical pathology in our laboratory for 26 years (1967-1992). A total of 915 cases were collected. Fibroadenoma was the most common lesion encountered (30.7%), followed by fibrocystic condition (21.1%), carcinoma (14.9%), acute mastitis (7.2%), duct ectasia (4.9%), lactational adenoma (4.8%), intraductal papilloma (2.6%), galactocele (2.4%) and several less frequent lesions. Pathological conditions associated with lactation such as acute mastitis, abscess, granulomatous mastitis, galactocele and lactational adenomas constituted 16.2% of the cases in this series. This high frequency is related to the high fertility rate among Saudi Arab females. The mean age of Saudi Arab females with ductal carcinoma was 47.1 years as compared to 54 years in Western countries. Many patients presented with a large size tumor, skin and/or nipple involvement, as well as a high frequency (61.7%) of axillary nodal metastases in those who underwent axillary nodal dissection. The high frequency of fibroadenoma could be related to the large number of young females in our population. A great increase in the number of cases in the last five years has been observed. This could be related to more awareness among Saudi Arab females of their health problems and the expansion of our medical services.
