In severe cases papillae undergo hypertrophy to produce cauliflower-like excrescences of 'giant papillae'. Bulbar form- It is characterised by dusky red triangular congestion of bulbar conjunctiva in palpebral area, gelatinous thickened accumulation of tissue around limbus and presence of discrete whitish raised dots along the limbus (Tranta's ...
There is no difference in age for predilection or incidence of concretions, due to the causes of conjunctivitis, aging, and even congenital factor. For statistical purposes Conjunctival Concretion is classified under the World Health Organization's ICD-10 category of H11.129 [1] and the ICD-11 category of 9A61.6. [2]
The conjunctival inflammation is called "active trachoma" and is usually seen in children, especially those in preschool. It is characterized by white lumps in the undersurface of the upper eyelid (conjunctival follicles or lymphoid germinal centers) and by nonspecific inflammation and thickening, often associated with papillae. Follicles may ...
In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull hairs straight), sebaceous glands (secrete sebum onto hair follicle, which oils the hair), sweat glands (can secrete sweat with strong odour or with a faint odour (merocrine or eccrine ...
Generally, diseases outlined within the ICD-10 codes H10-H13 within Chapter VII: Diseases of the eye, adnexa should be included in this category. Wikimedia Commons has media related to Disorders of conjunctiva .
The dermis is composed of three major types of cells: [3] fibroblasts, macrophages, and mast cells.. Apart from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan ...
The name describes a condition where several separate hair fibers bunch together and emerge from the skin through a single hair canal. Pathology shows that deep in the skin several dermal papillae are closely situated with each producing a fiber, but these separate hair follicle bulbs combine into one hair canal towards the skin surface.
The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]
