|---|---|---|---|
| 설명 | 피부 표피의 최상층에 있는 각질층이 증식-변화하여 까칠까칠해지거나 굳어지는 피부병-표피의 각질이 증식할 뿐만 아니라, 때로는 털주머니의 각층이 표피의 각층보다도 심하게 증식하여 구진을 형성하는 수가 있다. 각질은 표피세포가 각화하여 생기는 것으로, 정상적인 각화과정에서는 각층에 세포핵을 발견할 수 없다. 그런데 각질증식의 경우에는 세포핵이 잘 염색되어 존재한다. |

|---|---|---|---|
| 설명 | 일광각화증, 노인성각화증 등으로 불리는 이 병은 태양에 노출되는 부위에 나타나는 1cm 이하의 홍반성 각화구진이다. 즉 붉은 색을 띠는 껍질이 일어나는 모양을 한 융기가 약간 있는 그리고 경계가 비교적 명확한 둥근 모양의 병터이다. 이 병은 대개 햇볕노출이나 피부의 색조와 상관있고 약 20%에서 편평세포암종의 발생이 있어 치료를 필요로 한다. |

| Roentgen | <radiobiology, unit> The special unit of exposure, based on a quantity of ionisation (charge) produced by the absorption of X or gamma radiation energy in a specified mass of air under standard conditions. 1R = 2.58 x 10-4 C kg-1 or air. For radiation protection purposes, an exposure to 1 roentgen of x or gamma rays (air kerma of ~10-2 J kg-1) is generally assumed to produce an absorbed dose of 1 rad in water or soft tissue. Abbreviation: R (06 Aug 1998) |
|---|---|
| roentgen-equivalent | <radiobiology> A unit of dose equivalent to that quantity of ionizing radiation of any type that produces in man the same biologic effect as one rad of X-rays or gamma rays; the number of rems is equal to the absorbed dose, measured in rads, multiplied by the quality factor of the radiation in question.100 rem = 1 Sv. (05 Mar 2000) |
| roentgen-equivalent physical | <radiobiology, unit> A roentgen equivalent physical is a unit of absorbed radiation approximately equivalent to a roentgen, an international unit of x- or gamma-radiation. An obsolete unit of measurement; that quantity of ionizing radiation of any kind which, upon absorption by living tissue, produces an energy gain per gram of tissue equivalent to that produced by 1 roentgen of X-rays or gamma-rays. Acronym: rep See: rad. (05 Mar 2000) |
| roentgen ray | <investigation> A type of irradiation used for imaging purposes that uses energy beams of very short wavelengths (0.1 to 1000 angstroms) that can penetrate most substances except heavy metals. This is the commonest form of imaging technique used in clinical practice everywhere in the world with the image captured on photographic film. An AP film is when the beams pass from front-to-back (anteroposterior) and is used for mobile film, particularly on the ward or in casualty. This is the oposite to a PA film (posteroanterior) in which the rays pass through the body from back-to-front. Most films taken in the main radiology department are PA. (20 Jun 2000) |

| actinic keratosis | <dermatology> A skin lesion that is abnormally sensitive to the effects of ultraviolet light (sunlight). Thought to be a precancerous skin lesion that is more common in the fair-skinned or elderly individual. Approximately 20% of these skin lesions will develop into squamous cell carcinoma. Prevention includes the use of sun screen agents and the avoidance of drugs (for example tetracyclines) known to cause photosensitivity reactions. Usually a discreet slightly raised, red or pink lesion located on a sun exposed surface. Texture may appear as rough, gritty or scaly. Growths may be biopsied to look for cancer or removed via cryotherapy or electrical cautery. Some topical agents may be used to promote peeling. (27 Sep 1997) |
| arsenical keratosis | Multiple keratoses, most commonly of the palms and soles but also of the fingers and proximal portions of the extremities, resulting from long-term arsenic ingestion; they resemble Bowen's disease microscopically and may become malignant. (05 Mar 2000) |
| seborrheic keratosis | A benign skin lesion resulting from excessive growth of the top layer of skin cells. It usually is found in persons over 30 years old and may be few or numerous. (12 Dec 1998) |
| senile keratosis | <dermatology> A skin lesion that is abnormally sensitive to the effects of ultraviolet light (sunlight). Thought to be a precancerous skin lesion that is more common in the fair-skinned or elderly individual. Approximately 20% of these skin lesions will develop into squamous cell carcinoma. Prevention includes the use of sun screen agents and the avoidance of drugs (for example tetracyclines) known to cause photosensitivity reactions. Usually a discreet slightly raised, red or pink lesion located on a sun exposed surface. Texture may appear as rough, gritty or scaly. Growths may be biopsied to look for cancer or removed via cryotherapy or electrical cautery. Some topical agents may be used to promote peeling. (27 Sep 1997) |
| solar keratosis | A skin lesion that is abnormally sensitive to the effects of ultraviolet light (sunlight). Thought to be a precancerous skin lesion that is more common in the fair-skinned or elderly individual. Approximately 20% of these skin lesions will develop into squamous cell carcinoma. Prevention includes the use of sun screen agents and the avoidance of drugs (for example tetracyclines) known to cause photosensitivity reactions. Usually a discreet slightly raised, red or pink lesion located on a sun exposed surface. Texture may appear as rough, gritty or scaly. Growths may be biopsied to look for cancer or removed via cryotherapy or electrical cautery. Some topical agents may be used to promote peeling. (27 Sep 1997) |
| nevus follicularis keratosis | Comedo nevus, congenital or childhood linear keratinous cystic invaginations of the epidermis, with failure of development of normal pilosebaceous follicles. Synonym: nevus follicularis keratosis. (05 Mar 2000) |
| inverted follicular keratosis | A solitary benign epithelial tumour of infundibular hair follicle origin occurring on the face, consisting of a lobulated epidermal downgrowth of keratinizing squamous cells with a pattern of eddies or whorls. (05 Mar 2000) |
| tar keratosis | Warty lesions of the face and hands resulting from repeated, prolonged exposure to tar and pitch; also occurs as keratoacanthoma-like lesions that can become malignant, particularly on the scrotum. (05 Mar 2000) |
| keratosis | <dermatology> A skin lesion that is abnormally sensitive to the effects of ultraviolet light (sunlight).
