CD34 and neoplasm: In the following sections, we consider TC/CD34+SC behaviour in adipose tissue affected by pathologic processes, including inflammation and repair through granulation tissue, iatrogenic insulin-amyloid type amyloidosis, non-adipose tissue components and tumours growing in adipose tissue, adipose tissue tumours and other processes, such as the lipomatous hypertrophy of the interatrial septum, nevus lipomatosus cutaneous superficialis of Hoffman–Zurhelle and irradiated adipose tissue.
