Dermatoglyphics in thyroid cancer.
Digito-palmar dermatoglyphics in 93 subjects with thyroid cancer (34 males, 59 females) of which 87.1% had folliculo-papillar adenocarcinoma were studied qualitatively and quantitatively. The findings were compared to the dermatoglyphics of 100 males and 100 females from the clinically healthy autochthonous population. The thyroid cancer subjects had a lower total digital ridge count (TDRC) and a reduced number of papillar ridges between the a-d triradii, than the control subjects. The A line showed a more marked transversality in cancer males and a more marked obliquity in cancer females. Qualitative examination showed more patterns in the second interdigital area and a higher incidence of typical and atypical form of sulcus transversus in the cancer group as against the controls. Qualitative and quantitative variations in dermatoglyphics were found with respect to the relation between the anatomo-pathologic form and the A, B, or O blood group. However, this variation is not conclusive enough to support the hypothesis of an association between dermatoglyphics and the blood groups in the A, B, O system on the one hand, and dermatoglyphics and the anatomo-pathologic form of thyroid cancer, on the other.
