To report a case of a 25-year-old woman with previously treated peripheral T-cell lymphoma (PTCL) presenting with a recurrent lower eyelid lesion.Case report.A 25-year-old young woman with previously treated PTCL noted an induration in the skin of her left lower eyelid. Upon diagnosis of a chalazion, antibiotic eye drops and ointments as well as steroid eye drops were administered. However, the condition worsened rapidly and swelling of the lower eyelid became remarkable. An excisional biopsy revealed that the palpebral lesion was diagnosed as recurrence of PTCL. Electron irradiation was applied as a radical treatment, and the prognosis was satisfactory without recurrence at 10 months after the last irradiation.Although lymphoma isolated to the ocular adnexa is rare, it should always be included in the differential diagnosis of any patient presenting with progressive swelling of the eyelid or ocular region.
