Cutaneous Involvement of the Ear as the Sole Presenting Symptom in Recurrent Chronic Lymphocytic Leukemia: A Case Report.

Abstract

Cutaneous involvement of chronic lymphocytic leukemia (CLL) is rare but has been previously documented to involve the head and neck region. Generally, involvement to the ears is limited to the ear lobule; however, this study presents a unique case of recurrent CLL with cutaneous involvement overlying the auricular ear. The presentation was initially concerning for possible perichondritis but remained unresponsive to antibiotics and steroids. Eventual punch biopsy confirmed the recurrent CLL, although the lesion also presented with unique pathology, notably associated granulomata. This case demonstrates auricular involvement of CLL with unique pathology and highlights the importance of a widened differential and early, definitive tissue biopsy when evaluating refractory inflammation of the external ear.
