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.

Giant cell arteritis (GCA) is a large-vessel vasculitis that mainly affects women over fifty. GCA usually involves branches from the external carotid arteries, causing symptoms such as headaches, scalp tenderness, and jaw claudication. The most severe complication is ophthalmologic involvement, including acute anterior ischemic optic neuropathy and, less frequently, central retinal artery occlusion with a risk of permanent blindness. ⋯ General practitioners play a crucial role in early diagnosis, directing patients to specialized centres, and in managing ongoing treatment in collaboration with specialists. This collaboration is essential to address potential long-term complications such as cardiovascular events. They can occur five to ten years after the diagnosis of GCA even when the disease is no longer active, meaning that vigilant follow-up is required due to the patients' age and status.
