Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses , as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails ). [15] [16] While only a small number of skin diseases account for most visits to the physician , thousands of skin conditions have been described. [14] Classification of these conditions often presents many nosological challenges, since underlying etiologies and pathogenetics are often not known. [17] [18] Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane ), morphology ( chronic blistering conditions ), etiology ( skin conditions resulting from physical factors ), and so on. [19] [20] Clinically, the diagnosis of any particular skin condition is made by gathering pertinent information regarding the presenting skin lesion (s), including the location (such as arms, head, legs), symptoms ( pruritus , pain), duration (acute or chronic), arrangement (solitary, generalized, annular, linear), morphology ( macules , papules , vesicles ), and color (red, blue, brown, black, white, yellow). [21] Diagnosis of many conditions often also requires a skin biopsy which yields histologic information [22] [23] that can be correlated with the clinical presentation and any laboratory data. [24] [25] [26]

Study 4 was a randomized, multicenter, open-label trial in which 1466 patients were randomized to receive second-line treatment for metastatic NSCLC; 729 patients received IRESSA 250 mg daily and 715 patients received docetaxel. The median duration of treatment with IRESSA was months. The study population characteristics were: median age 61 years, age less than 65 years (61%), female (36%), Caucasian (79%), Asian (21%), NSCLC adenocarcinoma histology (54%), never smoker (20%), ECOG PS 0 or 1 (88%) and two or more prior therapies (16%).
