Overview

Tinea versicolor or pityriasis versicolor is a common skin infection caused by the yeast Malassezia furfur (formerly termed Pityrosporum ovale). This yeast is normally found on the human skin and only becomes troublesome under certain circumstances, such as a warm and humid environment.

Symptoms

The symptoms of this condition include:

Generally oval or irregularly-shaped spots of 1/4 to 1 inch in diameter, often merging together to form a larger patch
Occasional fine scaling of the skin producing a very superficial ash-like scale
Pale, dark tan, or pink in color, with a reddish undertone that can darken when the patient is overheated, such as in a hot shower or during/after exercise
Sharp border

These spots commonly affect the back, underarm, upper arm, chest, lower legs, and neck. Occasionally it can also be present on the face. The yeasts can often be seen under the microscope within the lesions and typically have a so called "spaghetti and meat ball appearance" as the round yeasts produce filaments.

In people with dark skin tones, pigmentary changes such as hypopigmentation (loss of color) are common, while in those with lighter skin color, hyperpigmentation (increase in skin color) are more common. These discolorations have led to the term "sun fungus".

Differential diagnosis

Tinea versicolor must be differentiated from other diseases presenting with an erythmatous, scaly, annular and pruritic rash. The differentials include the following:

Name of superficial infection	Clinical presentation	Extension to hair follicle	Fungus(i)	Systemic disease	KOH preparations	Morphology in tissue sections
Tinea or ringworm	Round lesions with scaly border, accompanied by pruritis and burning	Yes; when suppurative known as kerion, when chronic known as Majocchi's granuloma	Dermatophytes (Epidermophyton spp., Trichophyton spp., Microsporum spp.)	Very rare but can invade the dermis and soft tissues, causing mycetomas	Hyphae with or without septations	Hyphae cannot be visualized in the keratin with H&E, special stains are needed
Tinea versicolor	Hypo and hyperpigmentation in patients with oily and sweaty skin, fine scales when scratching	Yes, known as Pityrosporum folliculits	Malassezia spp.	Systemic infections may occur in premature neonates receiving parenteral nutrition and in other immunosuppressed hosts	Yeasts and hyphae (“spaghetti and meat balls”)	Faintly basophilic hyphae in the stratum corneum
Tinea nigra	Brown to black macule, usually on palms, with some scaling	No	Phaeoannellomyces werneckii	Not described	Darkly pigmented, septated, and branching hyphae	Pigmented hyphae in the stratum corneum
White piedra	Creamy-white, small, soft nodules in hair shafts	No	Trichosporon spp.	Immunosuppressed patients may have lung infiltrates, renal involvement, and fungemia	Septate hyphae perpendicular to hair shaft	Not used for diagnosis
Black piedra	Hard dark nodules in hair shafts	No	Piedraia hortae	Not described	Collections of crescent ascospores surrounded by pigmented hyphae	Not used for diagnosis
Superficial candidiasis	Intertrigo, chronic paronychia, onychodystrophy, cheilitis	Yes	Candida spp.	Yes, particularly in patients with AIDS and depending on the level of immunosuppression	Yeasts, pseudohyphae may be observed	Fungal elements may be seen through the biopsy, vascular invasion must be determined

Prevalence

Tinea versicolor is a common condition. It is estimated that 2 to 8% of the population of the United States has it. This skin disease commonly affects adolescents and young adults, especially in warm and humid climates. It is thought that the yeast feeds on skin oils (lipids) as well as dead skin cells.

Treatment

Treatments for tinea versicolor include:

Topical antifungal medications - containing either 2.5% selenium sulfide (Selsun® shampoo in UK, but not Selsun Blue which contains only 1%) or 2% ketoconazole (Nizoral® ointment and shampoo) applied to dry skin and washed off after 10 minutes, repeated daily for 2 weeks. Other topical antifungal agents such as clotrimazole, miconazole or terbinafine are less widely recommended. Additionally, hydrogen peroxide has been known to lessen symptoms, and on certain occasions, remove the problem.
Oral antifungal prescription only medications include 400 mg of ketoconazole or fluconazole in a single dose, or ketoconazole 200 mg daily for 7 days, or itraconazole 400 mg daily for 3-7 days. The single-dose regimens can be made more effective by having the patient exercise 1-2 hours after the dose, to induce sweating. The sweat is allowed to evaporate, and showering is delayed for a day, leaving a film of the medication on the skin.
Recurrence is common and may be reduced by intermittent application of topical agents (such as tea tree oil) or adding a small amount of anti-dandruff shampoo to water used for bathing.

Antimicrobial Regimen

Tinea versicolor^[2]

Alternative regimen: Fluconazole 400 mg PO single dose OR Itraconazole 400 mg PO q24h for 3–7 days

 ===Treatment===
 Treatments for tinea versicolor include:
-* [[Topical]] [[antifungal]] [[medication]]s - containing either 2.5% [[selenium sulfide]] (Selsun&reg; shampoo in UK, but not [[Selsun Blue]] which contains only 1%) or 2% [[ketoconazole]] (Nizoral&reg; ointment and shampoo) applied to dry skin and washed off after 10 minutes, repeated daily for 2 weeks. Other topical antifungal agents such as [[clotrimazole]], [[miconazole]] or  [[terbinafine]] are less widely recommended. Additionally, [[hydrogen peroxide]] has been known to lessen symptoms, and on certain occasions, remove the problem.

 * Oral  antifungal [[Prescription drug|prescription only medication]]s include 400 mg of [[ketoconazole]] or [[fluconazole]] in a single dose, or ketoconazole 200 mg daily for 7 days, or [[itraconazole]] 400 mg daily for 3-7 days. The single-dose regimens can be made more effective by having the patient exercise 1-2 hours after the dose, to induce sweating. The sweat is allowed to evaporate, and showering is delayed for a day, leaving a film of the medication on the skin.
 * Recurrence is common and may be reduced by intermittent application of topical agents (such as [[tea tree oil]]) or adding a small amount of anti-dandruff shampoo to water used for bathing.
