  • Lesion

    A lesion is any damage or abnormal change in the tissue of an organism, usually caused by disease or trauma. Lesion is derived from the Latin laesio "injury". Lesions may occur in plants as well as animals.

  • Stener lesion

    Stener lesion

    A Stener lesion is a type of traumatic injury to the thumb. It occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx. No longer in contact with its insertion site, the UCL cannot spontaneously heal.

  • Skip lesion

    A skip lesion is a wound or inflammation that is clearly patchy, "skipping" areas that thereby are unharmed. It is a typical form of intestinal damage in Crohn's disease, but may also be the kind of damage to the renal tubules in acute tubular necrosis. Rarely, it is a characteristic of temporal arteritis.

  • Molecular lesion

    A molecular lesion or point lesion is damage to the structure of a biological molecule such as DNA, enzymes, or proteins that results in reduction or absence of normal function or, in rare cases, the gain of a new function. Lesions in DNA consist of breaks and other changes in the chemical structure of the helix (see types of DNA lesions ) while lesions in proteins consist of both broken bonds and improper folding of the amino acid chain.

  • Perthes Lesion

    Perthes Lesion

    Perthes lesion is variant of Bankart lesion, presenting as an anterior glenohumeral injury that occurs when the scapular periosteum remains intact but is stripped medially and the anterior labrum is avulsed from the glenoid but remains partially attached to the scapula by intact periosteum.

  • Squamous intraepithelial lesion

    A squamous intraepithelial lesion (SIL) is an abnormal growth of epithelial cells on the surface of the cervix, commonly called squamous cells. This condition can lead to cervical cancer, but can be diagnosed using a Pap smear or a colposcopy. It can be treated by using methods that remove the abnormal cells, allowing normal cells to grow in their place. In the Bethesda system, the cytology can be graded as LSIL (low-grade squamous intraepithelial lesion) or HSIL (high-grade squamous intraepithelial lesion).

  • American Lesion

    American Lesion

    American Lesion is a solo album by Greg Graffin, the lead singer of the punk band Bad Religion. Like the album Into the Unknown , this album is a massive departure for Graffin, whose songs generally revolve around loud guitars and harmonies. American Lesion for the most part features Graffin's voice alone, and each song features acoustic guitar or piano rather than electric guitars. The song "Cease" (track 6 on this album) is a slow piano ballad that is also featured on Bad Religion's album The Gray Race as a fast-paced punk rock song.

  • Benign lymphoepithelial lesion

    Benign lymphoepithelial lesion is a type of benign enlargement of the parotid and/or lacrimal glands. This pathologic state is sometimes, but not always, associated with Sjögren's syndrome.

  • Target lesion

    In dermatology, a target lesion or bull's-eye lesion, named for its resemblance to the bull's-eye of a shooting target, is the typical lesion of erythema multiforme (EM) in which a vesicle is surrounded by an often hemorrhagic maculopapule. EM is often self-limited, of acute onset, resolves in three to six weeks, and has a cyclical pattern. EM lesions are multiform (polymorphous) and include macules, papules, vesicles, and bullae. Target lesions are also typical of erythema chronicum migrans.

  • Feline odontoclastic resorptive lesion

    Feline Tooth Resorption (TR) is a syndrome in cats characterized by resorption of the tooth by odontoclasts, cells similar to osteoclasts. TR has also been called "feline odontoclastic resorption lesion" (FORL), neck lesion, cervical neck lesion, cervical line erosion, feline subgingival resorptive lesion, feline caries, or feline cavity. It is one of the most common diseases of domestic cats, affecting up to two-thirds. TRs have been seen more recently in the history of feline medicine due to the advancing ages of cats, but 800-year-old cat skeletons have shown evidence of this disease. Purebred cats, especially Siamese and Persians, may be more susceptible.
