A case of teratoma of the thyroid gland in a 3-month-old child is reported. Present since birth, it presented as an acute respiratory emergency. This was relieved by surgical removal. The tumor showed normal thyroid tissue flanking the mass and at surgery was seen to derive its blood supply from the main thyroid vessels.
Blood group studies were conducted in 330 patients suffering from gastro intestinal disorders and 180 patients with congenital malformations and compared with normal subjects. Statistical analysis has shown that (a) there is significant correlation between B group and thalassaemia, (b) congenital malformations show higher incidence in B and O groups. It would be pertinent to draw attention to the fact that B group was found to be significantly correlated to duodenal ulcer from the present study contrary to the early reports. In addition, these observations show that blood groups are linked with diseases.
