Two cases in the literature may be designated "alternating" hemi- 

 hypertrophy, in analogy with the "alternating hemiplegia" of a pons 

 lesion, namely, those of Reissmann .and Behan, in which the face was 

 enlarged on one side, the arm and leg on the other. Other malformations, 

 such as syndactylism, enlargement of one or two digits, and undescended 

 testicle have sometimes been associated. 



From the above it may be concluded that hemihypertrophy, whatever 

 its ultimate cause and its mechanism may be, is a teratologic problem of 

 radically different pathogenesis than general gigantism.
