Cowden syndrome
Cowden syndrome is a rare genetic disease with the autosomal dominant inheritance, characterised by a combination of macrocephaly with multiple hamartomas and impaired lipid metabolism. The article presents a clinical case report of this disease in a 8-year-old boy with two genetically confirmed mutations in the genes PTEN and SHDB responsible for the development of Cowden syndrome. At present, there is insufficient evidence about the influence of combined pathogenic mutations in both genes and, consequently, about the possible outcomes and clinical manifestations of the disease. Taking into account the rarity of this pathology, multisystem organ involvement and also the absence of characteristic clinical signs in childhood, a description of this clinical case might be of interest in order to raise the awareness for Cowden syndrome. Key words: Cowden syndrome, hamartomas, PTEN, SDH, succinate dehydrogenase, hypoglycaemia, dyslipidemia
