Latent autoimmune diabetes of adults (LADA) is a type of autoimmune diabetes that begins in adulthood (usually after the age of 35 years); its main feature is the presence of diabetes-associated autoantibodies (most often autoantibody against glutamic acid decarboxylase), which leads to progressive destruction of the islets of Langerhans. This is a heterogeneous condition that presents with clinical and laboratory manifestations common to type 1 diabetes and type 2 diabetes.We report a case of a 71-year-old man diagnosed with type 2 diabetes two years ago, poorly controlled with oral antidiabetic therapy, and worsening in the third year. He had a positive family history of type 2 diabetes in two second-degree relatives (nephews). No pathologic findings at the physical examination were found.His body mass index was 23 kg/m 2 and glycated hemoglobin was 10.6%. Laboratory workup revealed low basal C-peptide (<0.1 ng/mL) and positive glutamic acid decarboxylase antibodies, and the LADA diagnosis was confirmed. This case highlights the importance of being aware of this disease, especially in patients previously diagnosed with type 2 diabetes who remain uncontrolled with diet and oral hypoglycemic agents. LADA is often confused with type 2 diabetes, and therefore, the management is frequently inadequate. An early diagnosis and treatment are crucial to delaying disease progression.

Younger patients and early referrals had better outcomes. Endothelin receptor antagonist toxicity should be monitored, particularly in patients previously exposed to hepatotoxic drugs.

SUMMARY The authors report a case of a 69-year-old man with idiopathic leukocytoclastic cutaneous vasculitis. For three years, the lesions recurred with progressive worsening and were associated with systemic manifestations of low-grade fever, weight loss and raised inflammatory markers. The patient latter presented a 6th cranial nerve involvement, raising the concern of a possible systemic vasculitis, which was latter evidenced by the development of deep vein thrombosis and angina pectoris. The treatment of the patient witch based on the decreasing of inflammatory activity, by using effective immunosuppressive therapy, with lower toxicity is more important than identifying the type of the vasculitis. This case illustrates the importance of awareness for the systemic involvement that can occur in up to 50% of patients with leukocytoclastic cutaneous vasculitis.
