Sarcoidosis is a multisystem disorder. Skin injury can have a wide range of semiologies. Ulcerated forms have rarely been described. ⋯ We report an original observation of cutaneous ulcerations revealing multisystemic sarcoidosis. Diagnosis of this rare form relies on skin biopsy and exclusion of other cutaneous granulomatoses. The evolution of ulcerative sarcoidosis is usually satisfactory with the usual treatments of sarcoidosis.

Metformin is a first line treatment for type II diabetes. Cases of metformin-associated lactic acidosis are regularly reported. A direct causal link between metformin overdose and lactic acidosis is not clearly established. The aim of this study is to describe cases of metformin-associated lactic acidosis, to assess their vital et renal prognosis, and to analyze the correlations between metforminemia, lactacidemia, pH and death. ⋯ Metformin-associated lactic acidosis is a rare complication. Its prognosis is inconstant, varying with the presence or absence of a severe disease causing the overdose. No association was found between clinical data, biological data and death.

Extramedullary hematopoiesis (EMH) is very rarely described during sickle cell disease (SCD). Our aim was to describe six cases of EMH occurring in adult SCD patients and to conduct a literature review. ⋯ EMH in SCD patients appears to be rare, with varied localizations. Its diagnosis is made with MRI and/or biopsy, and its treatment is not consensual.

Review Case Reports
[Chronic Q fever. Literature review and a case report of culture negative spondylodiscitis].
Fever is a cosmopolit zoonosis due to Coxiella burnetii. The diagnosis of chronic Q fever can be really misleading. The growth of this bacterium is difficult and blood cultures are often negatives. ⋯ Chronic Q fever and mostly osteoarticular diseases are difficult to diagnose. We have to evoke the diagnosis of osteoarticular chronic Q fever in case of insidious inflammatory syndrome, negatives blood cultures spondylodiscitis especially when associated to endocarditis or vascular infection, and in case of spondylodiscitis with a granulomatous histology without Mycobacterium tuberculosis. Although there are many complementary tests (PET scanner, PCR), serology remains the cornerstone of diagnosis.
