Piebaldism: rare but all dermatologists have heard this strange term during residency
- The Greek word of origin is:
- πομφολυξ = pompholyx = vesicle
- This term was given to what is now pemphigus by Robert Willan (a British physician, 1757-1817, the real founder of dermatology).
- Alibert (a French physician, 1766-1837) decided then to use this term for all bullous skin conditions originating from pemphix.
- This term will persist and afterwards this term will be used to describe vesicles on the hands (cheiro-pompholyx) and on the feet (podo-pompholyx). (considered as a type of endogenous eczema)
- Nowadays, this term is also known as dysidrosis and pompholyx is rather used for the presence of bullae when the vesicles merge. (often dysidrosis is spelled as dyshidrosis)
