These tumors are usually benign, but they can come back and cause the breast to look abnormal if not totally removed. Complex fibroadenomas are fibroadenomas harboring 1 or more complex pathologic features: epithelial calcifications, apocrine metaplasia, sclerosing adenosis, and cysts larger than 3 mm. Breast Pathology. Complex sclerosing lesions are benign breast masses characterized by a central dense collagenous stroma with a radiating proliferation of benign breast elements, including cysts, usual ductal hyperplasia, and adenosis.
