8. Sebaceous adenoma

 
Quotation from the 9th edition of Lever's:
 
"In terms of differentiation, sebaceous adenoma stands between sebaceous hyperplasia, in which sebaceous lobules appear fully or nearly fully matured, and sebaceous epithelioma or sebaceomaSebaceous adenoma and sebaceous epithelioma lack nuclear atypia and invasive, asymmetric growth patterns, which are hallmarks of sebaceous carcinoma."
 
Reference in the 9th edition to concepts contrary by A. Bernard Ackerman et al. (ABA): None.
 
Statements contrary by ABA:
 
"Sebaceous 'Adenoma' is Sebaceous Carcinoma. In short, in our judgment, so-called cystic sebaceous adenoma is really sebaceous carcinoma."
