This report describes the case of a 41-year old woman in treatment for advanced colorectal cancer who developed severe bilateral blepharitis and trichomegaly after the second dose of cetuximab. Cetuximab-related eyelid toxicity has been described previously; however, its pathogenesis has not yet been clearly established.

This report describes the clinical case of a 41-year old female patient with advanced colorectal adenocarcinoma who developed an intensely pruriginous eruption on her eyelids with a marked edema, erythema and desquamation following the second infusion of cetuximab (Figure 1). Examination using a DermLite DL100 dermatoscope revealed details of the desquamation and the presence of squamous, crusted, true perifollicular concretions, suggesting that the process had originated as a follicular reaction in the eyelashes. Onset of trichomegaly in the eyelids was also found (Figures 2 and 3). Non-contact epiluminescence light microscopy permitted the dermatologist access to details that would have been impossible to obtain without visual aid.
Cutaneous side effects occur in 80% of patients in use of cetuximab of which 15% are severe. 1 They generally appear during the first week of treatment. 1 The principal manifestations include acneiform eruptions, seborrheic dermatitis, paronychia, trichomegaly and maculopapular exanthemas.2,3
