Sections demonstrate a dense, non-neoplastic chronic inflammatory process characterized by a polymorphous infiltrate within a vascularized, edematous stroma. The cellular population is dominated by confluent sheets of mature plasma cells, interspersed with small lymphocytes and scattered eosinophils. Aggregates of epithelioid histiocytes are present. The background shows active neovascularization with thin-walled, congested capillaries and reactive myofibroblasts. No evidence of malignancy, or caseous necrosis is identified.
