Histiocytoses are a group of heterogeneous diseases that mostly comprise Langerhans cell histiocytosis (LCH) and non-LCH. The association of LCH with non-LCH is exceptional. We report 23 patients with biopsy-proven LCH associated with Erdheim-Chester disease (ECD) (mixed histiocytosis) and discuss the significance of this association. We compare the(More)
BACKGROUND Imatinib mesylate is a potent inhibitor of platelet-derived growth factor and transforming growth factor-β signalling pathways which may play a role in systemic sclerosis (SSc)-associated skin changes. OBJECTIVES We aimed primarily at assessing the efficacy of imatinib mesylate in scleroderma skin fibrosis. METHODS We performed a phase II(More)
BACKGROUND Mycobacterium chelonae is a ubiquitous, rapidly growing, opportunistic, non-tuberculous mycobacterium that can cause skin and bone tissue infections. We report a case of cutaneous infection due to M. chelonae following anti-TNF therapy. CASE REPORT A 70-year-old woman with a medical history of rheumatoid arthritis was admitted for several(More)
BACKGROUND X-linked dominant chondrodysplasia punctata, also known as Conradi-Hünermann-Happle syndrome, is a rare skeletal dysplasia characterized by short stature, craniofacial defects, cataracts, ichthyosis, coarse hair, and alopecia. Conradi-Hünermann-Happle syndrome is caused by mutations in the gene EBP encoding Δ(8)-Δ(7) sterol isomerase(More)
Stopping or preventing local bleeding in patients with inherited bleeding disorders linked to abnormal platelet function is traditionally treated by transfusion of blood cell products or recombinant factor VIIa. We now report the use in such patients of autologous platelet-rich clots as an aid to preventing bleeding and to facilitating tissue regeneration(More)
BACKGROUND Atrophic dermatofibrosarcoma is a rare clinical variant of dermatofibrosarcoma protuberans (or Darier-Ferrand tumor) preferentially observed in childhood and early adulthood. OBSERVATION We report a case of multifocal atrophic dermatofibrosarcoma protuberans of childhood onset only diagnosed when the patient was 29 years old. The clinical(More)
Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that affects medium- and small-sized arteries. We report the case of a 32-year-old female with PAN in which renal involvement was revealed by a secondary hyperaldosteronism. Hypokaliemia and arterial hypertension preceded rupture of renal artery aneurysm by several months. We believe that(More)
