|---|
| corpus cavernosum clitoridis | One of the two parallel columns of erectile tissue forming the body of the clitoris; they diverge at the root to form the crura of the clitoris. Synonym: cavernous body of clitoris. (05 Mar 2000) |
|---|---|
| corpus cavernosum conchae | Erectile tissue in the mucous membrane covering the conchae of the nasal cavity. Synonym: plexus cavernosi concharum, corpus cavernosum conchae. (05 Mar 2000) |
| corpus cavernosum penis | One of two parallel columns of erectile tissue forming the dorsal part of the body of the penis; they are separated posteriorly, forming the crura of the penis. Synonym: cavernous body of penis. (05 Mar 2000) |
| corpus cavernosum urethrae | The median column of erectile tissue located between and ventral to the two corpora cavernosa penis; posteriorly it expands into the bulbus penis and anteriorly it terminates as the enlarged glans penis; it is traversed by the urethra. Synonym: corpus cavernosum urethrae, spongy body of penis. Corpus spongiosum urethrae muliebris, the submucous coat of the female urethra, containing a venous network that insinuates itself between the muscular layers, giving to them an erectile nature. (05 Mar 2000) |
| lymphangioma cavernosum | A condition of conspicuous dilation of lymphatic vessels in a fairly circumscribed region, frequently with the formation of cavities or "lakes" filled with lymph. Synonym: cavernous lymphangiectasis. (05 Mar 2000) |
| atypical lipoma | <tumour> Lipoma, occurring primarily in older men on the posterior neck, shoulders, and back, which is benign but microscopically atypical, containing giant cells with multiple overlapping nuclei forming a circle. Synonym: pleomorphic lipoma. (05 Mar 2000) |
| CNS lipoma | <radiology> Incidence: less than1% of brain tumours, age: presentation in childhood/adulthood, associated with agenesis of corpus callosum in 50%, assymptomatic in 50% location: genu of corpus callosum (25-50%), tuber cinerum, quadrigeminal region, chiasmatic, interpeduncular, sylvian, CP angle, and cerebellomedullary cisterns findings: -100 HU on CT, occasionally calcified rim (especially in corpus callosum), no enhancement, hyperintense on T1 (characteristic) (12 Dec 1998) |
| pleomorphic lipoma | <tumour> Lipoma, occurring primarily in older men on the posterior neck, shoulders, and back, which is benign but microscopically atypical, containing giant cells with multiple overlapping nuclei forming a circle. Synonym: pleomorphic lipoma. (05 Mar 2000) |
| spindle cell lipoma | <tumour> A microscopically distinctive form of lipoma in which adipose tissue is infiltrated by fibroblasts and collagen; usually found in the shoulder or neck of elderly men. (05 Mar 2000) |
| infiltrating lipoma | A malignant tumour derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (liposarcoma, myxoid), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (12 Dec 1998) |
| telangiectatic lipoma | A benign neoplasm composed of a mixture of adipose tissue and blood vessels. (12 Dec 1998) |
| lipoblastic lipoma | A malignant tumour derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (liposarcoma, myxoid), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (12 Dec 1998) |
| lipoma | <oncology, tumour> Clumps of fat cells. Literally, fat cancer. These are benign tumours that can form in the breast. (16 Dec 1997) |
| lipoma annulare colli | An encircling growth of lipoma (or coalescent lipoma's) in the neck, resulting in a collar-like enlargement. See: Madelung's neck. (05 Mar 2000) |
| lipoma arborescens | An irregularly shaped lipoma involving the synovial membrane of a joint, resulting in fingerlike or treelike hyperplastic folds in the villi. (05 Mar 2000) |
