Resumen<br />

En los últimos años se han publicado numerosos artículos<br />

acerca <strong>de</strong> <strong>la</strong>s manifestaciones cutáneas re<strong>la</strong>cionadas<br />

con <strong>la</strong> administración <strong>de</strong> quimioterapia sistémica<br />

con 5-fluorouracilo.<br />

Aunque <strong>la</strong> toxicidad <strong>de</strong> este agente se manifiesta mayormente<br />

en <strong>la</strong> piel y sus anexos, <strong>la</strong>s afecciones cutáneas<br />

son poco frecuentes y al parecer <strong>de</strong>pen<strong>de</strong>n <strong>de</strong> <strong>la</strong><br />

dosis.<br />

Son varios los agentes terapéuticos conocidos por<br />

causar pigmentación cutánea durante el tratamiento<br />

y luego <strong>de</strong> él. Esta complicación parecería ser puramente<br />

estética, dado que casi nunca se asocia con toxicidad<br />

sistémica.<br />

Se presentan dos casos <strong>de</strong> hiperpigmentación por 5-<br />

fluorouracilo <strong>de</strong> patrón poco frecuente (<strong>Derm</strong>atol<br />

Argent 2002; Nº 5: 265-268).<br />

Summary<br />

Cutaneous reactions have been reported with the use<br />

of sistemic 5-fluorouracil. The toxicity of this agent is<br />

often conspicuosly disp<strong>la</strong>yed by the skin and its appendagges<br />

although eruptions associated with 5-<br />

fluorouracil are uncommon and seem to be <strong>de</strong>pen<strong>de</strong>nt<br />

on dose.<br />

Many chemotherapeutic agents are associated with<br />

hiperpigmentation. This complication if purely cosmetic<br />

concern and is not generally associated with sistemic<br />

toxicity.<br />

Pigmentation occurs in a variety of patterns and may<br />

involve the skin in a diffuse or localized fashion or involve<br />

the mucous membranes, hair and nails.<br />

Citotoxic drugs have resulted in numerous report of<br />

si<strong>de</strong> effects, hiperpigmentation is a frequent clinical<br />

feature in this patients.<br />

We report two cases of unussual pattern of hiperpigmentation<br />

associated to sistemic 5-fluorouracil.<br />
