[Keratosis linearis with ichthyosis congenita and sclerosing keratoderma (KLICK syndrome)]. / Queratosis linear con ictiosis congénita y queratodermia esclerosante (síndrome KLICK).

We describe the case of a 32-year-old male patient who had presented from birth with generalized ichthyosiform dermatosis, palmoplantar keratoderma with constrictive bands around the fingers and keratotic plaques in a linear arrangement, located in the large skin folds. The dermatopathological examination showed orthokeratotic hyperkeratosis and epidermal hyperplasia with hypergranulosis. No other members of the patient's family were affected. With these clinical and histological findings, the diagnosis was keratosis linearis with ichthyosis congenita and sclerosing keratoderma (KLICK syndrome). The patient rejected treatment with oral retinoids and was treated with emollients and 30 % urea creams, with little clinical response.

[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.
