| teratomatous cyst | A cyst containing structures derived from all three of the primary germ layers of the embryo. (05 Mar 2000) |
|---|---|
| ear cyst | A sebaceous cyst that occurs most commonly in the ear canal. They are bulging sac-like collections of dead skin cells and fluid. These cysts can be quite painful and may block the canal causing hearing loss. Treatment may include warm wet compresses, antibiotics (if infected) and surgical removal in some cases. Most resolve spontaneously. (27 Sep 1997) |
| echinococcus cyst | A cyst formed in the liver, or, less frequently, elsewhere, by the larval stage of Echinococcus, chiefly in ruminants; two morphological forms caused by Echinococcus granulosus are found in humans: the unilocular hydatid cyst and the osseous hydatid cyst; a third form in humans is the alveolar hydatid cyst, caused by Echinococcus multilocularis. Synonym: echinococcus cyst, hydatid. (05 Mar 2000) |
| thyroglossal cyst | <anatomy, embryology> A thyroglossal cyst is a fluid-filled sac that is present at birth and located in the midline of the neck. A thyroglossal cyst is a result of incomplete closure of a segent of a tube-like structure (the thyroglossal duct) that is present, and normally closes, as the embryo develops. Synonym: thyrolingual cyst. (07 Mar 2000) |
| thyroglossal duct cyst | A cyst in the midline of the neck resulting from nonclosure of a segment of the ductus thyroglossus. Synonym: cervical cyst. (05 Mar 2000) |
| thyrolingual cyst | A thyrolingual cyst is a fluid-filled sac that is present at birth and located in the midline of the neck. A thyrolingual cyst is a result of incomplete closure of a segent of a tube-like structure (the thyrolingual duct) that is present, and normally closes, as the embryo develops. A thyrolingual cyst is also called a thyroglossal cyst. (12 Dec 1998) |
| Tornwaldt's cyst | <anatomy> A cystic notochordal remnant found inconstantly in the posterior wall of the nasopharynx at the lower end of the pharyngeal tonsil. Synonym: bursa pharyngea, Luschka's bursa, Tornwaldt's cyst. (05 Mar 2000) |
| endometrial cyst | A cyst resulting from endometrial implantation outside the uterus, as in endometriosis. (05 Mar 2000) |
| endothelial cyst | A serous cyst whose sac is lined with endothelium. (05 Mar 2000) |
| ependymal cyst | A circumscribed distention of some portion of the central canal of the spinal cord or of the cerebral ventricles. Synonym: neural cyst. (05 Mar 2000) |
| trichilemmal cyst | A common cyst of the skin and subcutis which contains sebum and keratin, and is lined by pale-staining stratified epithelial cells derived from follicular trichilemma. Synonym: trichilemmal cyst. (05 Mar 2000) |
| epidermal cyst | Intradermal or subcutaneous saclike structure, the wall of which is stratified epithelium containing keratohyalin granules. (12 Dec 1998) |
| epidermoid cyst | A closed sac (sebaceous gland) within the tissue containing oily or fatty semi-solid material. These cysts are found most commonly on the genitalia, vulva or labia. Features include a nontender, small lump in the skin. Sebaceous cysts which turn red or tender may require treatment with oral antibiotics. Warm wet compresses may help the cyst expel some of its contents. Surgical excision of the cyst may be necessary to prevent recurrence. (27 Sep 1997) |
| epidermoid inclusion cyst | <radiology> Well-circumscribed radiolucent lesion showing a thin cortical margin that may not be visible in its entirety, frequently in the terminal phalanx, history of penetrating trauma is often elicited Differential diagnosis: ABC, enchondroma (12 Dec 1998) |
| epithelial cyst | A cyst lined with epithelium. (05 Mar 2000) |
