Introduction: In recent few decades, widespread use of mammography has resulted in increased detection of precursor and preinvasive breast lesions such as atypical ductal hyperplasia, ductal carcinoma in situ and, a type of breast lesion termed, ‘Flat epithelial atypia” which belongs to the group of columnar cell lesions with atypia. Although in India, invasive breast cancer is still most common presentation than early preinvasive lesions, with advanced diagnostic set up and increased awareness, early detection of preinvasive lesions is bound to be increased in future. For their accurate diagnosis, it is very necessary to be aware and alert about the morphology of these lesions.
Objectives: Present study was undertaken to study the morphology of Columnar Cell Lesion and other changes in Surgical Biopsy specimens received in Histopathology laboratory of a tertiary health care centre.
Materials and Methods: Excessive sections were taken from breast tissue surrounding the primary lesion in mastectomy or wide local excision specimens received over two-year duration and were examined for various changes in the epithelium and in the stroma especially columnar cell lesions and other precursor lesions.
Results: A spectrum of precursor lesions including columnar cell lesions could be commonly seen in most of the specimens. Their morphology and differential diagnosis could be studied in details in these sections which otherwise are wasted usually.
Conclusion: The tissue surrounding primary lesion in surgical pathology breast specimens is a good source to study the detailed morphology of columnar cell lesions and other lesions to get familiar with them for their accurate detection and early diagnosis in future.
