Reports of induction or exacerbation of psoriatic palmoplantaris pustulosis (PPPP) after anti-tumor necrosis factor-alpha (TNF-alpha) treatment are few. We describe 2 new cases of PPPP induced by infliximab. In 1999, a total of 442 patients in our department received anti-TNF-alpha treatment for a variety of chronic rheumatic conditions and were regularly(More)
Inaugural cutaneous metastasis is exceptional in osteosarcoma. We report a case of a woman with osteosarcoma of the right knee who presented two tumefactions of the scalp at the time of diagnosis. Magnetic resonance imaging identified a high intensity T2 signal in the femur and also a high-intensity signal in the soft tissues. The head scan confirmed the(More)
In Europe, human dirofilariasis refers to a group of autochtonous parasitic infections caused by tissue nematodes of the genus Dirofilaria, responsible for two distinct clinical presentations: Dirofilaria immitis usually presenting as pulmonary lesions and Dirofilaria repens as subcutaneous nodules. Rare in humans, genital involvement manifests itself as(More)
BACKGROUND Natalizumab is a monoclonal antibody directed against α₄ integrin used in the treatment of multiple sclerosis (MS). Four cases of melanomas occurring in patients prescribed natalizumab to treat MS were recently reported. Although some fundamental data suggested that α₄β1 integrin could be linked to the invasiveness of melanoma, none showed any(More)
Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that strongly influence molecular signalling in normal and cancer cells. Although increasing evidence suggests a role of PPARs in skin carcinogenesis, only expression of PPARgamma has been investigated in human melanoma tissues. Activation of PPARalpha has been(More)
