| lymphoma, small lymphocytic | A low-grade malignant lymphoma that may, in some cases, be considered histologically identical to chronic lymphocytic leukaemia (cll; leukaemia, lymphocytic, chronic). It is diffuse in pattern, representing the neoplastic proliferation of well-differentiated B-lymphocytes. In patients with immunoglobulin gammopathies, the lymphocytes may exhibit plasmacytoid characteristics. (12 Dec 1998) |
|---|---|
| lymphoma, undifferentiated | A form of lymphoma in which relatively large stem cells with large nuclei, pale, scanty cytoplasm, and indistinct borders are predominant. The cells are undifferentiated, i.e., show no morphologic evidence of maturation toward lymphocytes or histiocytes. (12 Dec 1998) |
| acute cutaneous leishmaniasis | A form of cutaneous leishmaniasis characterised by rural distribution of human cases near infected rodents, particularly communal ground squirrels; characterised by acute rapidly developing dermal lesions that become severely inflamed, with moist necrotizing sores or ulcers that heal in two to eight months after a two to four month incubation period; among nonimmune immigrants, multiple lesions may develop, which heal more slowly and leave disabling or disfiguring scars. A strong delayed hypersensitivity and involvement of immune complexes play a role in necrosis, which is part of the healing process and of the strong specific immunity that follows. Synonym: acute cutaneous leishmaniasis, rural cutaneous leishmaniasis, wet cutaneous leishmaniasis. (05 Mar 2000) |
| administration, cutaneous | The application of suitable drug dosage forms to the skin for either local or systemic effects. (12 Dec 1998) |
| anterior cutaneous branches of intercostal nerves | Medial mammary branches of anterior cutaneous branches of ventral primary rami of thoracic spinal nerves. See: medial mammary branches. (05 Mar 2000) |
| anterior cutaneous branch of iliohypogastric nerve | <anatomy, nerve> Distribution, skin on pubis. Synonym: ramus cutaneus anterior nervi iliohypogastrici, genital branch of iliohypogastric nerve. (05 Mar 2000) |
| anterior cutaneous nerves of abdomen | The ventral primary rami of spinal nerves T7-T11 (seventh to eleventh intercostal nerves), which supply the abdominal as well as the thoracic wall; innervate intercostal, subcostal, serratus posterior inferior, transversus abdominis, external and internal oblique, and rectus abdominis muscles, and provide sensory branches to the periphery of the diaphragm, and parietal pleura and peritoneum. Synonym: rami cutanei anteriores pectoralis et abdominalis nervorum intercostalium, ramus cutaneus anterior (pectoralis et abdominalis) nervorum thoracicorum, anterior cutaneous nerves of abdomen, pectoral and abdominal anterior cutaneous branch of intercostal nerves. (05 Mar 2000) |
| anterior femoral cutaneous nerves | Anterior cutaneous branches of femoral nerve; supplies distal 3/4 of skin and superficial fascia of anterior and medial thigh. Synonym: rami cutanei anteriores nervi femoralis. (05 Mar 2000) |
| anthroponotic cutaneous leishmaniasis | A form of Old World cutaneous leishmaniasis, usually with a prolonged incubation period and confined to urban areas. Synonym: chronic cutaneous leishmaniasis, dry cutaneous leishmaniasis, urban cutaneous leishmaniasis. (05 Mar 2000) |
| candidiasis, cutaneous | Candidiasis of the skin manifested as eczema-like lesions of the interdigital spaces, perleche, or chronic paronychia. (12 Dec 1998) |
| vasculitis, allergic cutaneous | Vasculitis due to allergic reaction, marked by such cutaneous lesions as papules, macules, vesicles, urticarial wheals, purpura, and small ulcers, and accompanied by itching and usually a slight fever and malaise. (12 Dec 1998) |
| passive cutaneous anaphylaxis | An evanescent cutaneous reaction occurring when antibody is injected into a local area on the skin and antigen is subsequently injected intravenously along with a dye. The dye makes the rapidly occurring capillary dilatation and increased vascular permeability readily visible by leakage into the reaction site. Pca is a sensitive reaction for detecting very small quantities of antibodies and is also a method for studying the mechanisms of immediate hypersensitivity. (12 Dec 1998) |
| passive cutaneous anaphylaxis test | An animal is injected intradermally with antibody (usually IgE) and subsequently challenged intravenously with a mixture of antigen and Evans blue dye 24-48 hours later. A dark blue area indicates a positive reaction due to the leakage of the dye at the site of antigen-antibody reactions. (05 Mar 2000) |
| medial antebrachial cutaneous nerve | <anatomy, nerve> Arises from the medial cord of the brachial plexus, passes downward in company with the brachial artery and then the basilic vein, and supplies the skin of the anterior and ulnar surfaces of the forearm. Synonym: nervus cutaneus antebrachii medialis, medial cutaneous nerve of forearm. (05 Mar 2000) |
| medial brachial cutaneous nerve | <anatomy, nerve> Arises from the medial cord of the brachial plexus, unites in the axilla with the lateral cutaneous branch of the second intercostal nerve, and supplies the skin of the medial side of the arm. Synonym: nervus cutaneus brachii medialis, lesser internal cutaneous nerve, medial cutaneous nerve of arm, Wrisberg's nerve. (05 Mar 2000) |
