Thrombogenic vasculopathy with diffuse neutrophilic inflammation: a histologic manifestation of a tick bite.
We describe 5 cases of tick bite reactions with dermal necrosis and sparse interstitial to dense diffuse dermal neutrophilic infiltrates associated with thrombogenic vasculopathy. Tick bite reactions classically consist of moderately dense perivascular infiltrates composed of an admixture of inflammatory cells. Each of our patients had embedded tick parts, with interesting histologic features.
