Epidermal growth factor receptor (EGFR) inhibitors have been used as anticancer agents for the treatment of a variety of solid tumors. Related skin toxicities are the most common adverse effects and occur with all EGFR inhibitors. Several treatment approaches, such as antiseptic soaps, topical and oral antibiotics, and topical and oral corticosteroids, have been reported; however, the responses have been varied. Acneiform eruption induced by EGFR inhibitor treatment results from disturbed normal keratinocyte and hair follicle biology and may therefore benefit from local restoration of EGF pathway.. We treated HaCaT cells with EGFR inhibitor and evaluated the expression of EGFR. After treatment of cells with EGFR inhibitor, EGFR expression was increased in a dose-dependent manner. We hypothesized that newly synthesized EGFR, not inhibited by EGFR inhibitors, may perform their biological action in keratinocytes in the presence of additional EGF. In this study, we therefore treated acneiform eruption patients with topical recombinant human EGF (rhEGF) with institutional review board approval. Here, we report three cases of such eruptions who responded to topical rhEGF.. Topical rhEGF may be an effective treatment option for EGFR inhibitor-induced acneiform eruption.

We report the cutaneous side effects of Iressa (ZD1839), a new anti-cancer agent that acts by inhibiting epidermal growth factor receptor signal transduction. The most common cutaneous adverse effect was the development of an acneiform eruption on the face, anterior trunk and back (39%). The second most common side effect was xerosis or desquamation of the face, body or distal parts of the fingers or toes (36%). Additional cutaneous side effects included multiple ingrown paronychial inflammation of the toes and fingers (6%), small ulcers of the oral mucosa or nasal mucosa, and urticaria. The cutaneous adverse effects of Iressa are similar to those of other epidermal growth factor receptor-targeted agents and result from direct interference with the functions of epidermal growth factor receptor signalling in the skin. Iressa-induced acne may be related to excessive follicular hyperkeratosis, follicular plugging, obstructions of the follicular ostium and alteration of hair cycle progression, which lead to an inflammatory response. Xerosis or desquamation reflects a disturbance of the equilibrium between proliferation and differentiation of epidermis. The mechanism by which Iressa leads to the development of paronychia and ingrown nail remains unclear.
