A patch of rashes on the body trunk and proximal extremities are generally known as Pityriasis versicolor disease. The yeasts that are normally found in the human body are responsible for this infection in a warm and totally humid environment. These are oval shaped spots that merge together to form patches. They may have fine scaling and dark tan, pale or pink in color. The color changes when the infected is overheated especially after a warm bath or exercise. The patches have sharp borders and have a pin pricking itching feel overtime. The beginning of sweating helps in stopping the pin prick feeling. The most common affected areas are back, upper arms, underarms, lower legs, chest and neck.
