Bannayan-Riley-Ruvalcaba syndrome (BRRS) is an overgrowth syndrome and polyposis condition, which carries an increased risk for development of benign and malignant tumors of various tissues and organs. A 9-year-old boy with BRRS who had multiple subcutaneous mesenchymal tumors and follicular adenoma of the thyroid and a 14-year-old boy with multiple subcutaneous mesenchymal tumors and gastrointestinal polyposis are presented, with special emphasis on the surgical management of these patients.

Summary Dermatoglyphic findings in 19 patients with phenylketonuria (11 male and 8 female), 39 of their relatives (18 female and 21 male) and 500 controls (TRC) were not statistically significant among the three groups studied. There was no definite relationship between the phenylketonuric gene and the dermatoglyphic patterns.

Dermatoglyphic findings in 19 patients with phenylketonuria (11 male and 8 female), 39 of their relatives (18 female and 21 male) and 500 controls (TRC) were not statistically significant among the three groups studied. There was no definite relationship between the phenylketonuric gene and the dermatoglyphic patterns. The parents of half the phenylketonuria cases are not consanguineous; thus the phenylketonuria gene may be more frequent in Turkey than other European countries.

Summary Antecubital pterygium syndrome is an abnormality characterized by congenital webbing of the elbow. The presence of this web limits the extension of the elbow at 90°. In this paper, a father and son with bilateral anomaly are described and the results of surgery are discussed.

In familial germ cell tumour cases, a normal chromosomal karyotype pattern is rare. We report the findings of germ cell tumours in two siblings with a normal chromosomal karyotype. One of these patients had dysgerminoma in the right ovary and was treated successfully for this. At present, she is 23 years old and has two daughters. The other patient is a 15‐year‐old boy, who is the brother of the first patient and has mediastinal embryonal carcinoma. Although ultrasonography of the testes showed irregularity in the shape and non‐homogeneity of the parenchyma, histopathological examination was found to be normal at the time of diagnosis. At present, he is doing well and his chemotherapy is continuing. Both of them have a normal chromosomal karyotype, 46, XX and 46, XY, respectively. We suggest that children who have a sibling with germ cell tumour should be carefully assessed for development of another germ cell tumour.
