Abstract:
Pseudolymphoma refers to a heterogenous group of benign reactive T- or B-cell lymphoproliferative processes of diverse causes that simulate cutaneous lymphomas clinically and/or histologically. This condition may be caused by known stimuli such as medications, infections or the bites of arthropods, or may be idiopathic. Herein we report a 36-year-old woman who developed a red nodule on the left neck following a tick bite 7 months earlier. Biopsy specimen of the left neck showed diffuse infiltrate of lymphocytes admixed with many eosinophils arrayed throughout the reticular dermis. The infiltrating cells were positive for UCHL-1, L-26(CD20) and focal positive for lambda-chain and kappa-chain, but negative for Bcl-2 and Bcl-6.
