Tangential shave biopsyTissue sample/scrape taken parallel to the skin while at the same time lightly pulling up the skin. This removes the superficial tumor and a smaller part of the depth.

Used by plastic surgeons in resection of burns and by dermatologists to remove seborrheic keratoses. Contraindicated in observation of malignant melanoma, as you do not have control over the exact margin of safety on both sides and bottom.
Tanner scale Classification for assessment of breast development and genital development. Used for assessment of gynecomastia (breast development in men) in plastic surgery.

TelangiectasiaPersistent dilatation of skin capillaries or minor venules. Often seen in basal cell carcinomas.
Third-degree burnA burn to the skin where all layers of the skin are affected, extending down into the subcutaneous layer. The lesion has brown/black edges. Scalding can cause the skin to appear white and leathery as well as firm and inelastic without bullae. In-depth, coagulated veins/arteries are visible. The lesion is without pain and a sense of pricking. The entire dermis is damaged, which is why regeneration can only happen from the wound edges and not the wound bed.

Tissue expansionProcedure in which a balloon/tissue expander prosthesis is placed under the skin and gradually filled with salt water to expand overlying skin. Subsequently, excess skin can be used to close the nearby defect, or simply hold a permanently drop-shaped breast prosthesis as seen during breast reconstruction.
TNMClassification of malignant tumors. T describes the primary tumor by size, depth of growth and/or local distribution. N describes whether there are metastases in regional lymph nodes such as the axilla. M describes whether there are distant metastases such as in the lungs or liver.

Tragus (ear)The posteriorly pointing cartilage projection in front of meatus acusticus externus.
TRAM-Flap (transverse rectus abdominis musculocutaneous flap)Stalked flap used for breast reconstruction. Excision of the musculus rectus abdominis, skin, fat and associated blood vessels is made. May cause problems with herniation and pain from the donor site. For that reason, the DIEP flap or LD flap is a more preferred method.
Transposition flap The local flap that is transposed/lifted and moved from nearby donor site to a defect. Frequently used flap, e.g. the nasolabial flap that is harvested from the cheek and transposed to the nose.

Traumatic woundWounds that have been caused by mechanical trauma to the skin, E.g. wounds caused by accidents and fights. This type of wound is seen primarily in the emergency room.
Tuberous breastsCongenital deformity of one or both breasts, characterized by a narrow tubular breast with an underdeveloped lower pole as well as an oversized areola-papilla complex.

Tumor free resection margins Pathological/histologic expression that all the tumor cells are completely excised and therefore no tumor cells are left in the bottom of the rim. 
In practice, the peripheral zone around the tumor is found without evidence of several millimeters of the malignant cells.
