Cutaneous T-cell lymphoma (CTCL) is significantly less common than B-c
ell lymphoma in patients with acquired immunodeficiency syndrome (AIDS
). Periocular involvement by CTCL usually occurs in the setting of mor
e widespread plaque or tumor-stage disease; therefore, CTCL localized
solely to the periocular region is rare. We report the case of a 38-ye
ar-old Hispanic woman with AIDS and an enlarging tumor of the left upp
er eyelid. The clinical differential diagnosis included various infect
ions and neoplasms. Examination of an incisional biopsy specimen revea
led a dense infiltrate of atypical lymphocytes that labeled as T cells
with use of the immunoperoxidase technique. The tumor subsequently re
gressed with local radiotherapy. Eyelid CTCL is reviewed and the diffe
rential diagnosis of eyelid lesions is reviewed.
