1. Small plaque parapsoriasis

 
Quotation from the 9th edition of Lever's:
 
"Relationship with lymphomait is generally accepted that the small plaque parapsoriasis, or digitate dermatosis, is a benign disorder without the potential of transformation into mycosis fungoides."
 
Reference in the 9th edition to concepts contrary by A. Bernard Ackerman et al. (ABA): None.
 
Statements contrary by ABA:
 
"Error: Small-plaque parapsoriasis (digitate and guttate dermatosis) is not mycosis fungoides. Reason: Small-plaque parapsoriasis, like large-plaque parapsoriasis, is a macular/patch expression of mycosis fungoides."
 
"Error: Some conditions termed parapsoriasis may convert into mycosis fungoides. Reason: Mycosis fungoides is a systemic lymphoma from the outset; small-plaque parapsoriasis, as but one example, cannot transform into mycosis fungoides because it is mycosis fungoides and, in fact, no inflammatory disease converts into mycosis fungoides."
