A 70-year-old woman presents for evaluation of an asymptomatic growth on her right wrist, which was noted approximately 2 months ago. She provides a history of longstanding severe psoriasis now well maintained on ustekinumab. She had previously received treatment with both etanercept and efalizumab, the latter during a Phase 2 clinical trial. She denies history of skin cancer. Examination revealed a 0.8-cm, flesh-colored papule with pigmented speckles.

Biopsy of the lesion revealed a nodular basal cell carcinoma, which was subsequently removed by excision.
Biologic therapies have revolutionized treatment of psoriasis with a highly acceptable risk-to-benefit ratio.1,2 Long-term extension of data gleaned from patients enrolled in clinical studies did not reveal an increased rate of skin cancers.3,4 However, an association with both squamous and basal cell carcinomas to tumor necrosis factor-inhibitor therapy has been suggested by additional clinical studies.5,6 Whether this patient’s basal cell carcinoma is related to previous biologic therapy is open to conjecture.
