Primary cutaneous anaplasic large-cell lymphoma involving medial canthus of the eyelid. / Linfoma anaplásico de células grandes primario cutáneo del canto medio palpebral.

Cutaneous anaplastic large-cell lymphoma (cALCL) is a condition within CD30 lymphoid proliferations spectrum. Involving the eyelid is unusual and all cases found in the literature are located in the upper eyelid. In this case we report an cALCL atypical presentation. A 39 year-old woman with no significant medical history, presents a fast-growing mass in the medial canthus, with inflamatory-infectious appearance. After a week with antibiotics with no response, an excisional biopsy was practiced. The hystopathology analysis with a negative systemic work up confirmed the diagnosis of a cALCL. After two-year follow up, patient is asymptomatic. cALCL involving the eyelid are rare but potentially life-threatening disorders, so more information about diagnosis, treatment and follow up is needed.
