Cutaneous pseudolymphoma: an unusual eyelid presentation.

Pseudolymphoma is an inflammatory response to known or unknown stimuli that results in a lymphomatous-appearing but benign accumulation of inflammatory cells. Resemblance to lymphoma is usually most apparent histologically. Most cases are idiopathic. Approximately three-quarters of cases of cutaneous pseudolymphoma are localized with the most common site on the face (70%), chest, and upper extremities. We would like to report an unusual eyelid presentation of cutaneous pseudolymphoma, not previously reported. It is therefore important to consider cutaneous pseudolymphoma as a differential diagnosis of eyelid lesions.
