Abstract
Purpose
Atypical ductal hyperplasia (ADH) is a lesion with significant malignant potential. We evaluated the prevalence of breast carcinoma in surgical breast biopsies performed on palpable breast lesions diagnosed initially as ADH by fine needle aspiration cytology (FNAC).
Materials and Methods
Between January 1, 1996 and December 31, 1997, 942 patients performed FNAC at the Department of Surgery and Pathology, College of Medicine, Hallym University and Department of Surgery, Central Gil Hospital were analyzed. ADH was found in 46 (4.9%) of 942 patients, and surgical excision subsequently was performed in 39 of these cases. In these 39 cases, cytologic and histopathologic results from FNAC and surgical biopsies were reviewed and correlated.
