Histopathological Analysis of 62 Cases of Tick Bite with Tick

Abstract

62 specimens of tick bite with tick were examined to establish histopathologic diagnostic criteria. The most common histopathologic findings are extravasation of erythrocytes in dermis 62/62 (100%), sclerosis of dermal collagen fibers 59/62 (95.2%), epidermal necrosis 54/62 (87.1%), ulcer 47/62 (75.8%), neutrophilic cell infiltration in dermis 46/62 (74.2%). We believe that these findings are useful clue for histopathological diagnosis of tick bite in the absence of tick parts.
