Tinea versicolor
- Tinea versicolor is a common cutaneous fungal infection which may chronically recur
- TV most frequently occurs in sub-tropical and tropical regions with high temperatures and high humidity
- Patients present with hypopigmented or hyperpigmented macules and patches often on the back and chest
- A fine scale is often seen
- Lesions are usually asymptomatic but some lesions are itchy
- Tinea versicolor is caused by a dimorphic, lipophilic fungus of the genus Malassezia, formerly known as Pityrosporum
- Histopathology reveals fungal hyphae and spores (spaghetti and meatballs) within the stratum corneum
- Associated hyperpigmentation and acanthosis can also be seen in some cases
- Topical antifungal agents are the first line treatment of choice
