1/10. Isolated scalp involvement with pityriasis versicolor alba (pityrias versicolor albus capitis) in a patient from a dry, temperate region.Pityriasis versicolor (tinea versicolor) is a common superficial fungal infection of the skin involving the hyphal (filamentous) form of Pityrosporum orbiculare. Clinical cutaneous infection is common in humid, tropical climates, but declines to less than 5 percent in temperate climates. Isolated face or scalp involvement is rare. We present a boy living in a temperate region who had sudden onset of scalp and hairline involvement with tinea versicolor.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
2/10. tinea versicolor mimicking pityriasis rubra pilaris.tinea versicolor is a common noninvasive cutaneous fungal disease. We recount a case of tinea versicolor that mimicked type I (classic adult) pityriasis rubra pilaris. A 54-year-old white man reported a 20-year history of a recurrent pruritic eruption that had marginally improved with use of selenium sulfide shampoo and treatment with oral antihistamines. Results of a skin examination revealed erythematous plaques; islands of spared skin; and follicular erythematous keratotic papules on the trunk, shoulders, and upper arms. A lesion was scraped to obtain skin scales for potassium hydroxide staining. Examination of the stained samples revealed the characteristic "spaghetti and meatballs," confirming the diagnosis.- - - - - - - - - - ranking = 0.5keywords = tinea (Clic here for more details about this article) |
3/10. Confluent and reticulated papillomatosis associated with tinea versicolor in three siblings.We describe three teenage siblings with confluent and reticulated papillomatosis, all presenting during a 6-month period. Two of the three patients had confirmed tinea versicolor, with positive potassium hydroxide scrapings, in association with this entity. This is the largest series of siblings with confluent and reticulated papillomatosis, and the only report describing family members having both confluent and reticulated papillomatosis and tinea versicolor. This report lends further evidence to the hypothesis that confluent and reticulated papillomatosis may be etiologically linked to tinea versicolor, and also suggests a genetic predisposition for it.- - - - - - - - - - ranking = 3.5keywords = tinea (Clic here for more details about this article) |
4/10. Hyperkeratotic head and neck malassezia dermatosis.BACKGROUND: Pityriasis versicolor (tinea versicolor) is a common skin disorder due to malassezia usually affecting adolescents and young adults, more frequently in the tropics. Facial involvement, isolated or not, is not frequent in white adults. OBJECTIVE: Here, we report a possible atypical hyperkeratotic form of dermatosis of the face, in two young immunocompetent Caucasian patients, particularly recalcitrant to therapy. RESULTS: skin scrapings grew yeasts belonging to the genus malassezia, including both M. globosa and M. sympodialis. This unusual variant needs long-term therapy with systemic and topical imidazoles together with facial cleansing. CONCLUSION: We propose the name hyperkeratotic head and neck malassezia dermatosis for this distinctive clinical entity. This variant of pityriasis versicolor should be considered in the differential diagnosis of seborrheic dermatitis and dermatitis neglecta.- - - - - - - - - - ranking = 0.5keywords = tinea (Clic here for more details about this article) |

6/10. tinea versicolor of the face in black children in a temperate region.tinea versicolor is a common superficial fungal infection that typically affects young adults in warm, humid climates. We describe two young black children in the temperate northeastern ohio area with tinea versicolor limited to the face. The occurrence of tinea versicolor on the face is unusual, as is its appearance before puberty. The mycologic and pathophysiologic characteristics of tinea versicolor infection are discussed, and several hypothesis are offered to explain the presence of tinea versicolor in these patients.- - - - - - - - - - ranking = 2keywords = tinea (Clic here for more details about this article) |
7/10. Intravenous catheter-associated malassezia furfur fungemia.malassezia furfur, a lipophilic yeast that is the etiologic agent of tinea versicolor, has not been considered as a cause of serious illness in adults in the past. Two adults are described in whom malassezia furfur fungemia developed while receiving total parenteral nutrition supplemented with lipids. The organism was identified in blood cultures from both patients only after isolation media were supplemented with a source of fatty acids. Because M. furfur will grow only in media supplemented with fatty acids, clinicians should alert the laboratory whenever a lipophilic organism is suspected to be present in blood cultures.- - - - - - - - - - ranking = 0.5keywords = tinea (Clic here for more details about this article) |
8/10. tinea versicolor: a light and electron microscopic study of hyperpigmented skin.hyperpigmentation in lesions of tinea versicolor has previously been reported to be a result of the effects of the fungus Pityrosporon orbiculare on melanosome formation and distribution. Examination of biopsy specimens from lesions of hyperpigmented tinea versicolor involving vitiliginous skin reveals an absence of melanosomes and melanocytes. Reddish-tan and fawn-colored hyperpigmentation in tinea versicolor of this type is not due to melanin pigment. The possible nature of the pigmentation that delineates hyperpigmented tinea versicolor from normal skin is discussed.- - - - - - - - - - ranking = 2keywords = tinea (Clic here for more details about this article) |
9/10. Scanning electron microscopic evaluation of tinea versicolor. Effects of treatment with miconazole nitrate and clotrimazole.A study of tinea versicolor organisms was conducted in one patient by scanning electron microscopy. Morphologic changes in the organisms during treatment with topical clotrimazole and miconazole nitrate consisted of initial wrinkling of the surface, followed by fragmentation. These changes may have reflected cell wall alterations resulting from inhibited ergosterol synthesis induced by both treatment agents. The two drugs were effective in eliminating the organisms.- - - - - - - - - - ranking = 2.5keywords = tinea (Clic here for more details about this article) |
10/10. An unusual case of tinea versicolor in an immunosuppressed patient.A most unusual case of tinea versicolor is presented in which the eruption was localized only to the patient's flexural areas. This is an additional case of tinea versicolor appearing in a renal transplant patient undergoing immunosuppressant therapy. The role that immunosuppressive agents may have played in this case is also presented.- - - - - - - - - - ranking = 3keywords = tinea (Clic here for more details about this article) |
