Cicatricial ectropion associated with treatment of metastatic colorectal cancer with cetuximab.

Cetuximab is a monoclonal antibody that binds to the epidermal growth factor receptor (EGFR) of cancer cells expressing EGFR and prevents dimerization and downstream cell signaling pathways. It has been shown to prolong survival in patients with metastatic colorectal cancer. Cutaneous toxicity is relatively common because of the inhibition of EGFR of normal epidermal cells.

Iridoschisis and bilateral lens subluxation associated with periocular eczema.

We present a 53-year-old man with bilateral lens subluxation, unilateral iridoschisis, and a long-standing history of periocular eczema. Although a case of unilateral lens subluxation and ipsilateral iridoschisis has been described recently, the pathogenesis of this simultaneous occurrence remains unclear. Our case raises questions about the relationship among these clinical observations and suggests that these findings may exist as part of an unrecognized oculodermal syndrome.
