Pityriasis (tinea) versicolor is a benign, superficial, common fungal infection localized to the stratum corneum.
It occurs most commonly in postpubertal individuals when the sebaceous glands are the most active.
Facial involvement is common in adolescents, but lesions are also found on the upper trunk, neck, arms, dorsum of the hand and pubis.
Patient presents with erythematous, hypo- or hyperpigmented macules or patches that may have a slight scale.
It is caused by the lipophilic yeast Malassezia furfur.
Intraoperative epidural analgesia, perioperative opioid and total dose of volatile agent appear to show some “clinically meaningful associations” with relapse-free survival (RFS) in children with solid organ tumour, particularly in paediatric sarcoma patients, according to a Singapore study. However, no statistically significant association exists between epidural use and an improved RFS.
