| clear cell | A cell in which the cytoplasm appears empty with the light microscope, as occurs in certain secretory cells of eccrine sweat glands and in the parathyroid glands when the glycogen is unstained, any cell, particularly a neoplastic one, containing abundant glycogen or other material that is not stained by haematoxylin or eosin, so that the cell cytoplasm is very pale in routinely stained sections. (05 Mar 2000) |
| clear cell acanthoma | A sharply demarcated benign epidermal lesion of a leg or arm with acanthosis and accumulation of glycogen in keratinocytes having pale staining cytoplasm. (05 Mar 2000) |
| clear cell adenocarcinoma | <tumour> A histologic type of renal adenocarcinoma. A histologic type of adenocarcinoma occurring chiefly in the male and female genitourinary tracts which is characterised by distinctive hobnail cell growth of neoplastic cells in sheets, papillae, and coalescing glands. (05 Mar 2000) |
| clear cell carcinoma of kidney | <radiology> Hypernephroma, renal cell carcinoma, arises from proximal collecting tubule, 10% bilateral adenocarcinoma types: papillary, alveolar, onchocytoma vascularity, 85% hypervascular (require pre-op embolization), 10% hypovascular (usually papillary type), 5% avascular associated with: tuberous sclerosis, von Hippel-Lindau syndrome see also: staging (12 Dec 1998) |
| clear cell hidradenoma | <tumour> A tumour derived from eccrine sweat glands, composed of glycogen-rich clear cells. Synonym: eccrine acrospiroma, nodular hidradenoma. (05 Mar 2000) |
| clear layer of epidermis | A layer of lightly staining corneocytes in the deepest level of the stratum corneum; found primarily in the thick epidermis of the palmar and plantar skin. Synonym: clear layer of epidermis. (05 Mar 2000) |
| clear liquid diet | A diet, often used postoperatively, consisting usually of water, tea, coffee, gelatin preparations, and clear soups or broth. (05 Mar 2000) |
| water-clear cell of parathyroid | A variety of chief cell, so-called because the cytoplasm contains much glycogen that is not preserved or stained in the usual preparation. Synonym: wasserhelle cell. (05 Mar 2000) |
| sarcoma, clear cell | A sarcoma of young, often female, adults of the lower extremities and acral regions, intimately bound to tendons as circumscribed but unencapsulated melanin-bearing tumours of neuroectodermal origin. An ultrastructural finding simulates flattened and curved barrel staves, corresponding to the internal structures of premelanosomes. There is a 45-60% mortality in clear cell sarcoma. (12 Dec 1998) |
