Painful, aseptic osteitis remains the major problem in the treatment of patients with SAPHO syndrome. We present a child suffering of both sacroiliitis and acne conglobata in the context of SAPHO syndrome. While acne lesions responded well to systemic isotretinoin, sacroiliitis associated pain could be controlled neither by NSAR nor by intralesional or systemic steroid injection. Worse pain limited substantially patient's mobility. This changed immediately after starting etanercept. Within a few days, pain resolved and the patient regained his mobility. This favourable response lasted for 8 months when we tried to stop etanercept under protection with the DMARD sulfazalazin. Unfortunately, within a few days, pain and immobility re-occurred requiring reinstitution of etanercept. This case demonstrates that, similar to other reports, TNF blockade is able to induce prompt and long-lasting response of SAPHO syndrome associated osteoarthritis to TNF blockade.

A patient with clear cell renal cell carcinoma was treated with sorafenib, a multikinase inhibitor, which induced a variety of cutaneous side effects. In addition to xerosis, he developed angioedema (AE), hand-foot syndrome (HFS) and perforating folliculitis (PF). The latter three occurred in a dose-dependent manner. AE was observed at the recommended daily dose of 800 mg. Dose reduction to 400 mg prevented its recurrence. At this dose level, the patient exhibited HFS, which cleared upon further reduction of the dose. While receiving 200 mg, the patient developed PF. To the best of our knowledge, this is the first description of a case of PF during treatment with sorafenib.
