| keratitis, dendritic | A form of herpetic keratitis characterised by the formation of small vesicles which break down and coalesce to form recurring dendritic ulcers, characteristically irregular, linear, branching, and ending in knoblike extremities. (12 Dec 1998) |
| keratitis, herpetic | A superficial, epithelial herpes virus hominis infection of the cornea, characterised by the presence of small vesicles which may break down and coalesce to form dendritic ulcers (keratitis, dendritic). (12 Dec 1998) |
| kerato- | A confusing prefix it can refer to the cornea (as in keratitis and keratocornea) or to horny tissue (as in keratin and keratosis). (12 Dec 1998) |
| keratoacanthoma | A benign, non-neoplastic, usually self-limiting epithelial lesion closely resembling squamous cell carcinoma clinically and histopathologically. It occurs in solitary, multiple, and eruptive forms. The solitary and multiple forms occur on sunlight exposed areas and are identical histologically; they affect primarily white males. The eruptive form usually involves both sexes and appears as a generalised papular eruption. (12 Dec 1998) |
| keratoangioma | A discrete, pink to red telangiectasia having a tendency to undergo secondary epithelial changes, including acanthosis and hyperkeratosis. An underlying vascular abnormality is present in many cases. The term angiokeratoma is applied to a number of quite distinct conditions which share a common clinical presentation with asymptomatic hyperkeratotic vascular skin lesions and a histological combination of superficial dermal vascular ectasia.

| keratoconjunctitis | Inflammation of the eye involving both the cornea and conjunctiva. (12 Dec 1998) |
| keratoconjunctivitis | <ophthalmology> Inflammation of the cornea and conjunctiva. (18 Nov 1997) |
| keratoconjunctivitis sicca | Drying and inflammation of the conjunctiva as a result of insufficient lacrimal secretion. When found in association with xerostomia and polyarthritis, it is called sjogren's syndrome. (12 Dec 1998) |
| keratoconjunctivitis, infectious | Infectious diseases of cattle, sheep, and goats, characterised by blepharospasm, lacrimation, conjunctivitis, and varying degrees of corneal opacity and ulceration. In cattle the causative agent is moraxella (moraxella) bovis; in sheep, mycoplasma, rickettsia, chlamydia, or acholeplasma; in goats, rickettsia. (12 Dec 1998) |
