It is a lesion with loss of substance of the cutaneous coating, with little tendency to the spontaneous scaring, it is of type [trófica] for circulatory ecstasy and it representes 80 between the 70% you of them ulcerate vascular.
The localization preferential is the inferior third of the leg by being the most exposed zone to micro-traumatism and infections, by not having good muscular support and present perforans that transmits the waves hiperreactivity to the superficial tissues without subduing.

The skin for their circular tension tends to don't allow to approach the borders.
They are but frequent in the feminine sex.

Their Physiopatology this related with the phenomenon of veined chronic hypertension that create alterations hemodynamics in the venulo-capillary circuit, with increase of the pressure hydrostatic and edema, necrosis fat, fibrosis and sclerosis that finish altering the arterial glasses.
The zone appears atrium, with alteration of the tissues and of color ocher or reddish. Upon taking place the micro-traumatism, they begin ulcerate that they increase progressively of size in circumference feeling and longitudinal.

One could observe lesions of irregular or nets borders, reddish, bleeding to the close contact where they could present capillaries of neo-formation or on the contrary be sanious with necrosis purulent, oozing liquidates thick for added infection. The depth is variable, could arrive to the periosteum.
In general, the patient refers pain especially if infection is added. In the zone peri-ulcerous could observe lesions of dermatitis scaly pigmentary or impetiginous alternating with dry zones.

Their natural evolution, upon not being tried, it is the increase of size, deepening it and even arriving to the fibrosis of the surrounding fabric.
The ulcerate post-rhomboid could be present in any of their clinical degrees, adopting several characteristics.
The mixed forms are the most common. The lesions edematous is dermopathy with processes of cellulitis induratin, fibrosis with or without it ulcerate.

The treatment of an ulcerates is, frequently, lingering. It is fundamental establish an diagnose between the different types of you ulcerate, since the treatment differs if their etiology is veined, arterial, of infectious origin, metabolic, thermal or for radiant body.
The local cure has a provisional characteristic and should go accompanied by always the correction of the cause producer, from the pathology of base.

The local treatment seeks to reach the following objectives:
- Cleaning of the wound.
- Protection of polluting agents.
- Stimulate the scaring.

He made of clean a wound correctly is going to have a direct relationship with the optimistic of the necessary conditions so that this cicatrize correctly and that the danger of infection diminishes, since with the cleaning, they retire microorganisms and material necrótic present in the channel of the lesion.

It will be made if it present necrosis, sphacelus or detritus. It is essential so that a wound cicatrize correctly since the fabric necrótic or the sphacelus are broth of cultivation for infections, they begin an inflammatory answer, they suppose a demand phagosoma for the wound and they retard the cure upon representing a mechanical barrier for the tissue of granulation.

It have been observed that you ulcerate exudative they cure more slowly than the not exudatives, the excess of oozing could macerate the surrounding tissue.
