Histologically, sebaceous hyperplasia consists of enlarged lobules of mature sebaceous glands with a central dilated duct. |
Case 1 was highly cellular, contained scattered cells with argyrophilic granules, and was not associated with cancerization of lobules. |
Lobular carcinoma in situ within the ducts and lobules of nipple showed absence of reactivity with E-cadherin. |
The lobules in complexly marginal fluting branch and expand to form deep lobes. |
This classification was based on the belief that ductal carcinomas arose from ducts and lobular carcinomas from lobules. |
The lesion displayed unremarkable pancreatic lobules with acini, ducts, and islets of Langerhans cells. |
