Abstract
BACKGROUND: We report a patient with chronic lymphocytic leukemia (CLL) that developed recurrent vesicobullous lesions that histologically demonstrated features of an exaggerated response to an arthropod bite. OBJECTIVE: Patients with CLL can present with many cutaneous manifestations, including specific and nonspecific lesions. Although rare, patients with CLL can develop an exaggerated response to an arthropod bite. CONCLUSION: Emphasis needs to be placed on the clinical recognition of arthropod bites as an unusual cutaneous manifestation of CLL, as they provide the physician with both a diagnostic and a therapeutic challenge. Patients often deny being bitten and, thus, the biopsy results conflict with the patient's history. Additionally, as there is no specific treatment, both the patient and physician are faced with a similar dilemma. Although our patient initially responded well to corticosteroids, his lesions significantly improved while being treated with dapsone.
