Abstract
To investigate the role of immunecomplexes (Ic) in type 2 reaction (ENL), tissue fragments of 22 reactional leprosy patients were studied by means of direct immunofluorescence techinique (DIF) in association to routine histopathology. Results showed immunecomplexes in vessel and in the membrance of the dermal-epidermal junction (BMZ). The presence of lc in the deep dermal vessels and in subcutaneous tissue in connection to necrotizing vasculits alteration suggest the participation of these complexes in type 2 reaction (ENL)
