1. Kaposi's sarcoma (KS) is about 1 / 3 AIDS patients at the first examination had KS. KS is a multifocal tumor, manifested as skin, blood vessels of multiple nodules, a few may be violations of internal organs. At the beginning of hand, foot, leg (still pre-emptive in the nose, helix, nipples, eyelids, penis, abdominal wall, etc.), and then slowly toward the concentric expansion, spread to the trunk, head, face, neck, genitalia, etc., the number of up to 100 or more. Lesions to red or purple rash, papules, nodules or plaques, is diffuse infiltration or bleeding. Diameter from sorghum, lentils m to vary in size, scattered or in clusters. There was sponge-like uplift, texture firm who, a few showed verrucous, papillary or cauliflower-like tumors. Subjective symptoms are not noticeable, or partially swollen, with pain, burning, itching. 10% of the patients had visceral damage, sequential involving lymph nodes, gastrointestinal tract, lung, liver, pericardium, adrenal gland, bladder, thyroid, bone, brain, vocal cords, tonsils and so on. If the only damage to internal organs without skin lesions, is more of fever, weight loss, lymph nodes and hepatosplenomegaly, anemia and so on.
It should be noted that generally do not die of AIDS patients-pulmonary KS, and more died in the immune suppression caused by infectious complications. Therefore, tumor staging, in addition to degree of tumor lesions, we must also focus on patients with systemic symptoms and immune status. In AIDS patients, PCP occurred accounted for 50% ~ 60%, and KS, 26%, while there are KS and PCP in 8%, and other infections 15%.
2. Non-Hodgkin's lymphoma, AIDS pandemic, distribution and non-Hodgkin's lymphoma was a parallel between the incidence of relationship. Lymphoma, 95% occurred in lymphoid outside the organization, can occur in any part of the body and can spread to the bone marrow, liver, central nervous system, digestive tract and so on. Clinically, AIDS patients tend to malignant lymphoma, a high degree of histological types and clinical course of invasive 『. Primary central nervous system lymphoma in the histological type are often the primary immune cells of these patients showed a single mass within the brain parenchyma, while the body transferred to the central nervous system lymphoma, often located in meningeal lymphoma. Primary non-Hodgkin's lymphoma in the bone marrow, primarily the performance of fever, anemia, bleeding tendency, infection syndrome, blood and bone marrow as an exception like. Gastrointestinal lymphoma can occur in any part of the esophagus to the anus, manifested as abdominal distention pain, abdominal mass, bowel movement abnormalities, and gastrointestinal bleeding. Lymphoma patients with poor prognosis, the majority die within 6 months. Primary central nervous system lymphoma in patients with shorter survival period, usually 2 to 4 months.
3. Other cancer and papilloma-related anal cancer and cervical cancer in HIV infected persons more common. As women. HIV infection rates increase in the incidence of cervical cancer is increasing, therefore, in the HIV infected women, cervical checks need to be carefully carried out to detect early malignant lesions.
