Observations:
Etanercept is a human recombinant soluble tumor necrosis factor (TNF-α) receptor fusion protein. Etanercept has been used successfully to treat a wide range of inflammatory disorders including psoriasis and psoriatic arthritis resistant to classical disease-modifying treatments. The widespread use of TNF-α antagonists led to the recognition of adverse effects. Herein, we report a case of palmoplantar pustular psoriasis in a 37-year-old man during the etanercept therapy.
