Lipomas are usually sporadic, asymptomatic lesions, and their clinical and histologic presentation does not pose diagnostic difficulties. In ambiguous cases, however, knowledge of genetics is necessary. HMGA2 expression in adipose cells enables the differentiation of normal adipose tissue from lipoma and liposarcoma. Moreover, lipomas can be associated with genetic diseases, such as multiple endocrine neoplasia type 1, neurofibromatosis type 1, Wilson's disease, or mitochondrial diseases. Lipomas can run in families (familial multiple lipomatosis) or be a part of genetic syndromes such as PTEN hamartoma tumor syndrome, Proteus syndrome, and Pai syndrome. This study aims to present the genetic basis of lipomas and diseases in which these lesions occur in the clinical picture.

Arterial hypertension (HT) is one of the most common lifestyle diseases worldwide, including Poland. According to World Health Organization, as many as 1.28 billion adults worldwide were suffering from HT in 2011 -a half were unaware of their disease. It is claimed that approximately 10 million of deaths annually are the result of improperly high blood pressure values (BP) [1]. It is estimated that the number of HT patients will exceed 1.5 billion by 2025. Therefore, it classifies HT as a major global healthcare problem [2].According to the WOBASZ II study, more than 40% of the adult Polish population were diagnosed with HT. A constantly increasing trend of newly di-
