Psoriasis

Definition

Psoriasis is a chronic, non-contagious disease characterized by inflamed hyperproliferative lesions covered with silvery-white scabs of dead skin.

Description

Psoriasis, which affects at least four million Americans, is slightly more common in women than in men. Although the disease can develop at any time, 10–15% of all cases are diagnosed in children under 10, and the average age at the onset of symptoms is 28 years of age. Psoriasis is most common in fair-skinned people and relatively rare in dark-skinned individuals, although the rate among African Americans appears to be slowly rising.

Breast reconstruction

Definition

Breast reconstruction is a series of surgical procedures performed to recreate a breast. Reconstructions are commonly begun after portions of one or both breasts are removed as a treatment for breast cancer. A breast may need to be refashioned for other reasons such as trauma or to correct abnormalities that occur during breast development.

Wide local excision

Definition

Wide local excision is a type of surgery for breast cancer. It is considered “breast-conserving” surgery because only the malignant tumor and a surrounding margin of normal breast tissue are removed. Lymph nodes in the armpit (axilla) may also be removed. This procedure is also called lymph node dissection.
