A female patient with a clinical picture of Turner's syndrome had five separate malignant tumors (three squamous cell carcinomas of the tongue, a colon cancer, and a glioblastoma multiforme). Her peripheral blood cells showed a 45,X/46,XXp-/46,XX/47,XXX mosaicism. The findings are discussed in relation to other extragonadal tumors in Turner's syndrome reported to-date.

A study of cancer incidence in a cohort of 597 women with Turner syndrome (TS) and a virtually complete follow-up is presented. The cohort was established from the Danish Cytogenetic Register. Information on cancer incidence was obtained from the Danish Cancer Registry and compared with the expected number calculated from the age-, period- and site-specific cancer rates for Danish women. A total of 21 neoplasms was observed, of which 13 occurred more than 1 year after diagnosis of TS, corresponding to a relative risk of cancer of 1.1. Wilms' tumour was the only identified childhood cancer. No case of gonadoblastoma or dysgerminoma was identified in the 29 women with a Y chromosome or in the women in whom no Y chromosome material was detected by standard cytogenetic methods, suggesting that the risk of ovarian germ cell tumours may be lower than previously estimated. Colon cancer was observed in five patients (relative risk 6.9, 95% confidence interval 2.2-16.2). Further studies are needed to assess whether colon cancer in TS is related to Turner-associated genes on the sex chromosome(s).

A 14-year-old female with Turner syndrome (karyotype 45,X) had a history of abdominal pain with distention, constipation, and fever. She was first operated on for the suspicion of appendicitis, failed to improve, and was later hospitalized for further investigation and treatment. Studies demonstrated an obstructing tumor of the transverse colon, and an emergency laparotomy was performed. The final diagnosis was a signet-ring cell carcinoma of the colon with diffuse peritoneal dissemination and metastasis to paracolic lymph nodes. On the basis of this case, we report the association of Turner syndrome with malignancies and also some aspects of colon cancer in childhood.
