Background: Drug-induced eyelid edemas are rare. Herein, we describe a patient who developed this type of edema under chemotherapy. Patients and methods: A year-old male patient with a history of hypertension and adenocarcinoma of the lung with brain metastases consulted for incipient non-itchy eyelid edema with progressive worsening.
The swelling occurred after 3 cycles of pemetrexed-carboplatin. There was no evidence of any other cause of edema. A diagnosis of pemetrexed-induced eyelid edema was made. Given the efficacy of this treatment and the patient's consent thereto, it was maintained.
Discussion: Palpebral edemas secondary to pemetrexed are very rare, with only 22 published cases in the literature. Other differential diagnoses must be ruled out before considering this etiology. The pathogenesis of eyelid edema remains unknown.
One hypothesis is capillary protein leakage inducing swelling in soft tissue and non-malignant effusion, as has been suggested for docetaxel. Other agents such as tyrosine kinase inhibitors imatinib and nilotinib and mTOR inhibitors sirolimus may also cause eyelid edema.
Treatment of eyelid edema is difficult and one case of surgical treatment has been published with good results and no recurrence after 6 months.
