Minor N.Ny., a 2-year-old girl, was examined in 1986 in a contested paternity case by an order of court. The defendant did not admit paternity and named another man, so anthropological and blood-group examinations were performed on mother, child and the two men. Giving expert opinion may prove to be difficult following anthropological examinations for developmental anomalies of either party. However, the observed disease or developmental anomaly may have clinical importance for parties examined 'by chance'. In our case morphological deviation was detected in mother.
