Author: admin, 25.01.2014Oral candidiasis or candidosis is mainly caused by the yeast Candida albicans, although other Candida species often cause infection. Erythematous candidiasis is a poorly understood condition associated with corticosteroids, topical or systemic broad-spectrum antibiotics, or HIV disease. The lesions in hyperplastic candidiasis present as chronic, discrete raised areas that vary from small, palpable, translucent, whitish areas to large, dense, opaque plaques (Fig. Candida-associated denture stomatitis, also called denture sore mouth or chronic atrophic candidiasis, is one of the most common ailments in wearers of full dentures; in some areas such as Scandinavia, 60% of wearers over 60 years old were reported to suffer from the condition.
A few patients have chronic candidiasis from an early age, sometimes with a definable immune defect, e.g. Candidiasis is usually restricted to the skin and mucous membranes but may occasionally spread and manifest systemically (multisystem involvement). All forms of oral candidiasis are considered to be opportunistic infections, and the epithet ‘disease of the diseased’ has been applied to these infections, which are seen mainly in the ‘very young, the very old and the very sick’. Primary oral candidiases: localized candidal infections present only in the oral and perioral tissues.
Secondary oral candidiases: candidal infections that manifest in a generalized manner both in the oral cavity and in other mucous and cutaneous surfaces (systemic mucocutaneous candidal infections).
35.2 Pseudomembranous candidiasis (thrush) of the palate in a human immunodeficiency virus (HIV)-infected individual. It may arise as a consequence of persistent acute pseudomembranous candidiasis when the pseudomembranes are shed, or may develop de novo. 35.3 Erythematous candidiasis of the palate in a human immunodeficiency virus (HIV)-infected individual. 35.5 Histopathological section of a chronic hyperplastic candidiasis lesion showing numerous candidal hyphae infiltrating the superficial layers of the oral epithelium. It has also been shown that the occurrence of an otherwise unexpected mycosis (typically oral candidiasis) in an HIV-infected individual is a poor prognostic indicator of the subsequent development of full-blown AIDS (see also Chapter 30). Systemic forms of candidiasis may affect only one organ or be disseminated (candidal septicaemia, candidaemia). These are due to rare disorders (except perhaps in candidiasis of human immunodeficiency virus (HIV) infection) such as thymic aplasia and chronic endocrine diseases.
Hence, some consider pseudomembranous and the erythematous variants a continuum and a single entity (i.e. The combination of oral and oesophageal candidiasis is particularly prevalent in HIV disease. Erythematous candidiasis of the palate is a common Candida-associated lesion frequently observed in elderly people wearing full dentures (Candida-associated denture stomatitis; see below). However, in HIV-infected populations on antiretroviral therapy, the incidence of oral candidiasis has significantly declined.
Oral cancer supervenes in 9–40% of cases of hyperplastic candidiasis, as compared with the 2–6% risk of malignant transformation cited for oral white patches in general.
