Cutaneous Pseudolymphoma Secondary to Insect Bite: A Case Report

Introduction Cutaneous Pseudolymphoma (CPL) encompasses a heterogeneous group of benign, reversible, and inflammatory lymphocyte proliferation. Case presentation We present a unique instance of CPL triggered by an insect bite in a 42-year-old female who presented to our hospital with a solitary tender erythematous shallow ulcer over her right arm, which was misdiagnosed initially as cutaneous leishmaniasis due to her travel history. A biopsy ultimately revealed cutaneous lymphoid hyperplasia related to an arthropod bite reaction. Moreover, various treatment options were initiated. Conclusion This case highlights the need for clinicians to consider CPL in the differential diagnosis of chronic skin lesions to avoid misdiagnosis and ensure appropriate treatment.
