Lesions affecting the terminal duct lobular unit (TDLU) in breast are all except –
Correct Answer: Nipple adenoma
Description: If you know the structural architecture of breast, this question is very simple
The breast comprises a branching system of duct leading down from the nipple ending in glands(acini aggregated into lobules) which have potential to secrete milk
Approximately 12 large ducts emerge from the breast at nipple as lactiferous ducts.
Their subdivisions form rather complicated breast segments that are discrete physiologically, but probably interdigitate with each other at their boundaries.
The ducts branch repeatedly ultimately giving rise to the terminal duct lobules unit (TDLU). In simple words, successive branching of the large ducts eventually leads to terminal duct lobular unit (TDLU).
The tissue between the ducts and glands is composed of fat and fibrous tissue, and is called stroma. Stroma makes up the bulk of the volume of the adult breast.
