TLDR EGFR inhibitors can cause yellowish skin eruptions.
The document reported a case of a 43-year-old woman who developed perifollicular xanthomas, characterized by a yellowish papular eruption, during a treatment change from cetuximab to panitumumab, both of which are epidermal growth factor receptor (EGFR) inhibitors. EGFR inhibitors are commonly used in the treatment of various solid tumors due to their role in cell proliferation, differentiation, and angiogenesis. However, these inhibitors often cause cutaneous side effects, including acneiform skin reactions, xerosis, and changes in hair and nails, due to EGFR expression in normal epidermis and associated structures.
