[Adult-onset colloid milium. Presentation of two cases]. / Milio coloide del adulto. Presentación de 2 casos.

Colloid milium is a degenerative process that is characterized clinically by the development of translucent, yellow, 1-2 mm papules located in photoexposed areas. Histologically, deposits of a colloid substance are seen in the papillary dermis. We present two cases of this infrequent pathology in two male patients, who had been subjected to intense sun exposure because of their work. We initiated treatment with photoprotective creams and topical tretinoin, with little clinical improvement.
