lesion

injury or loss. In the civil law jurisdictions the word is often used in the context of an ‘unfair’ loss, as where an adult takes advantage of a minor or someone purchases something for much less than it's worth.

LESION, contracts. In the civil law this term is used to signify the injury suffered, in consequence of inequality of situation, by one who does not receive a full equivalent for what he gives in a commutative contract.
     2. The remedy given for this injury, is founded on its being the effect of implied error or imposition; for in every commutative contract, equivalents are supposed to be given and received. Louis. Code, 1854. Persons of full age, however, are not allowed in point of law to object to their agreements as being injurious, unless the injury be excessive. Poth. Oblig. P. 1, c. 1, s. 1, art. 3, Sec. 4. But minors are admitted to restitution, not only against any excessive inequality, but against any inequality whatever. Poth. Oblig. P. 1, c. 1, s. 1, art. 3, Sec. 5; Louis. Code, art. 1858.
     3. Courts of chancery relieve upon terms of redemption and set aside contracts entered into by expectant heirs dealing for their expectancies, on the ground of mere inadequacy of price. 1 Vern. 167; 2 Cox, 80; 2 Cas. in Ch. 136; 1 Vern. 141; 2 Vern. 121; 2 Freem. 111; 2 Vent. 359; 2 Vern. 14; 2 Rep. in Ch. 396; 1 P.

Dieulafoy lesion (DL), although an uncommon cause of non-variceal UDB, may cause potentially life-threatening bleeding, especially in the elderly ([2]).
For the accurate selection of the Dieulafoy lesion patient group, the medical and endoscopic records of these patients were reviewed in order to meet the diagnostic criteria of Dieulafoy lesions.
Out of the total number of 2104 patients with non-variceal upper digestive bleeding, 31/2104 (1.5%) have presented endoscopic bleeding from a Dieulafoy lesion. 19/31 (61.3%) were male and 12/31 (38.7%) female (Figure 1), mean age 63 [+ or -] 12.83 years (range 23-83 years).
Dieulafoy lesion is a rare but potentially fatal etiology of gastrointestinal bleeding due to its ability to cause significant acute life threatening hemorrhage.
In conclusion, one must always be mindful to keep Dieulafoy lesion as part of their differential diagnosis when evaluating any individual of any age who presents with acute gastrointestinal hemorrhage, even in the absence of significant comorbidities or risk factors.

At a distance of approximately 5-6 cm from the anal verge, an active Dieulafoy lesion was observed.
Dieulafoy lesion is one of the well-defined causes of acute massive gastrointestinal bleedings.
Typically, patients with Dieulafoy lesion are old, and this lesion is twice common in men.
Miko and Thomazy, (5) who carried out measurements of the diameter of mucosal and submucosal arteries of patients with Dieulafoy lesion as well as control subjects, support that theory.
A Dieulafoy lesion remains asymptomatic unless mucosal erosion exposes the underlying artery, causing it to bleed.
