Miliaria Crystallina: Sudamina…

Miliaria Crystallina is also known as Sudamina.  Miliaria is a common skin disease caused by blockage and/or inflammation of eccrine sweat ducts.  Miliaria Crystallina more specifically is due to obstruction of the sweat ducts close to the surface of the skin in the stratum corneum of the epidermis.  The lesions are characterized by small, clear, superficial vesicles with no inflammatory reaction.

ETIOLOGY:  It appears most frequently in bedridden patients (see above) whose fever produces increased perspiration or when clothing prevents dissipation of heat and/or moisture, as in bundled children.  It affects up to 9% of neonates with a mean age of 1 week.  Drugs such as isotretinoin, bethanechol, and doxorubicin may induce Sudamina.

TREATMENT:  No treatment is required.  Certainly treating any underlying condition producing sustained fevers is a must.  The lesions themselves are self-limited and resolve spontaneously.  To read more about Miliaria Crystallina click HERE and HERE.
