A CASE IS LINKED TO HISTOPATHOLOGY GROUP TOO:  
 
24 yrs Lady suffered from multiple biopsies (incl. excissional) with scarring due to multifocal lymphoid follicular hyperplasia (pseudolymphoma) from 2012 till now.  
Eruptions: violaceus, elevated (photo included), around postbiopsy scars.  
Biopsies: 2012 LEFT brachial skin, 2013 RIGHT humeral skin, 2015 RIGHT cheek/face...  
 
HISTO in all biopsies the same: tumoral, deep, fibrotic follicular hyperplasia. Only 2012 largest excission is included (2013 and 2015 smaller biopsies).  
 
IH: Nothing special in all biopsies: Bcl2(-) II follicles, no expansions of MZ or abberrancies. Ig kappa/lambda polytypical.  
Serology: Ab titers against Borrelia absent.  
MOLECS: IGH, IGK, TCRB, TCRG ir TCRD locuses- NONclonal profile.  
 
PROPOSAL/QUESTION: B lymphoid hyperplasia (multifocal/disseminated): what the cause is?
