83 yrs lady with "cutaneous AILT" diagnosed twice in general oncology dept with possibly "surgical way of thinking" (2007 "Ca cutis reg. cruris"-2013 "fibroma reg. cruris"). Local radiation after each episode (wise?) without haematological evaluation (BM absent) and chemo.  
2014: reexcision.  
MACRO: 6,5x3,5x0,5 cm skin piece with irregular induration 4,3x3 cm.  
HISTO: Vaguelly nodular, vascularised, effected by fibrosis (postradio-?) heterogenous infiltrate, enreached by atypical spindle and "histyoid" cells and scant T CD4+ lymphos admiture.  
IH:  
MOLECS:  
2014: B/T polyclonal.  
2007: pending.  
 
Question: definite classification of cutanous elderly LPD vs mesenchymal lesion? Other? (?)(AILT is not there...).
