A. 10 month old male infant brought to the ER on a sweltering day of June. He is listless, cranky and "floppy as dishrag". He has no hair or teeth.

While I agree with the answers, Q.3 doesn't make much sense.....it says ambiguous genitalia yet the testes arent palpable??It would be clearer if you could give the complete question....thanks.
Does anyone know whats the disease in Q.1??

Ectodermal dysplasia seems to be the diagnosis in Q1

Ectodermal dysplasia is not a single disorder but has variants. This looks like the anhydrotic form, in which sweat glands are the ones which are worst affected.
Not sure though. Opinions welcome.
