Acute generalized exanthematous pustulosis (AGEP) is a rare acute reaction that is drug induced in 90% of the cases and characterized by a widespread, sterile pustular rash. Erlotinib, a small-molecule EGFR tyrosine kinase inhibitor, has been approved by the FDA for patients with pancreatic cancer and non-small cell lung cancer. Skin rash is a well-known side effect related with all EGFR blocking agents. It has been suggested that rash could be used as a surrogate marker for response and possibly be associated with prolonged survival. We report a case of rare presentation of AGEP involving an adverse effect of erlotinib. The commonly reported adverse effects of erlotinib are mild skin eruptions. However, our case describes the rare presentation of AGEP induced by erlotinib. The estimated incidence rate of AGEP is approximately 1-5 cases per million/year.

Acute generalized exanthematous pustulosis (AGEP) is a pustular eruption, mainly drug induced often accompanied by fever and neutrophilic leukocytosis presenting as scarlatiniform erythema over the flexures evolving into numerous tiny non follicular pustules. We present a case report of a 56-year old woman, who had undergone mastectomy, treated with lapatinib for metastatic disease, and who presented with multiple erythematous papules and plaques with peripheral pustules. She also developed painful pyogenic granuloma-like lesions over the pulp of toe and over the proximal nail folds.All the lesions subsided following withdrawal of lapatinib. Although AGEP has been reported with imatinib (a multikinase inhibitor), there have been no reports of serious reactions with lapatinib, an EGFR inhibitor. This case could represent the first case report of AGEP to the EGFR inhibitor, lapatinib.
