| perforating folliculitis | Erythematous papules with a central keratin plug which are scattered on the arms, thighs, and buttocks; seen especially in diabetics on haemodialysis. See: hyperkeratosis follicularis et parafollicularis. (05 Mar 2000) |
|---|---|
| eosinophilic pustular folliculitis | A dermatosis characterised by sterile pruritic papules and pustules that coalesce to form plaques with papulovesicular borders; spontaneous exacerbations and remissions may be accompanied by peripheral leukocytosis, eosinophilia, or both, and may result in eventual destruction of hair follicles and formation of eosinophilic abscesses. The disease has been reported in AIDS, and a possibly separate form of eosinophilic pustular folliculitis occurs in infants. Synonym: Ofuji's disease. (05 Mar 2000) |
| eosinophillic folliculitis | <pathology> An inflammatory reaction around hair follicles, characterised by very itchy papules that may grow together to form plaques. The cause of this condition in people with AIDS has yet to be established, although the condition obviously involves invasion of the follicles by eosinophils. Partially successful treatment has been reported with ultraviolet light, steroids, antihistamines and itraconazole. (09 Oct 1997) |
| folliculitis | <dermatology> Inflammation of a follicle or follicles, used ordinarily in reference to hair follicles, but sometimes in relation to follicles of other kinds. (12 Nov 1997) |
| folliculitis abscedens et suffodiens | A chronic progressive follicular-pustular eruption in the scalp. (05 Mar 2000) |
| folliculitis barbae | Tinea of the beard, occurring as a follicular infection or as a granulomatous lesion; the primary lesions are papules and pustules. Synonym: barber's itch, folliculitis barbae, ringworm of beard, tinea sycosis, trichophytosis barbae. (05 Mar 2000) |
| folliculitis decalvans | A papular or pustular inflammation of the hair follicles of the scalp seen mostly in men, resulting in scarring and loss of hair in the affected area. Synonym: acne decalvans, alopecia follicularis. (05 Mar 2000) |
| folliculitis keloidalis | A type of acneiform disorder in which secondary pyogenic infection in and around pilosebaceous structures ends in keloidal scarring. It manifests as persistent folliculitis of the back of the neck associated with occlusion of the follicular orifices. It is most often encountered in black or asian men. (12 Dec 1998) |
| folliculitis nares perforans | Inflammation of a hair follicle in the nose; the infection extends to, and perforates, the cutaneous surface. (05 Mar 2000) |
| folliculitis ulerythematosa reticulata | Erythematous "ice-pick" or pitted scars on the cheeks; a scarring type of folliculitis, associated with keratosis pilaris and commonly inherited as an autosomal dominant trait. Synonym: atrophoderma vermiculatum. (05 Mar 2000) |
| recurrent pyogenic cholangitis | Repeated attacks of cholangitis, commonly noted among Asians living in Asia, associated with the presence of multiple intrahepatic and extrahepatic bile duct stones and strictures. (05 Mar 2000) |
| granuloma, pyogenic | A usually solitary polypoid capillary haemangioma of the skin and gingival or oral mucosa, often associated with trauma or local irritation, representing a vasoproliferative inflammatory response. It presents as a small erythematous papule that enlarges and may become pedunculated and may become infected and ulcerate with accompanying purulent exudate. The haemangioma without suppuration is called angiogranuloma. Pyogenic granuloma is not a granuloma: the name refers to the mass of inflamed, highly vascular granulation tissue. (12 Dec 1998) |
| pyogenic | <microbiology> Producing pus, pyopoietic which is the liquid inflammatory product made up of cells and a thin fluid called liquor puris Origin: Gr. Gennan = to produce (18 Nov 1997) |
| pyogenic arthritis | Acute inflammation of synovial membranes, with purulent effusion into a joint, due to bacterial infection; the usual route of infection is hemic to the synovial tissue, causing destruction of the articular cartilage, and may become chronic, with sinus formation, osteomyelitis, deformity, and disability. Synonym: purulent synovitis, pyarthrosis, pyogenic arthritis, suppurative synovitis. (05 Mar 2000) |
| pyogenic bacterium | A bacterium that causes a pyogenic infection, such as the pyogenic cocci (staphylococci, streptococci, pneumococci, meningococci) and Haemophilus influenzae. (05 Mar 2000) |
