Patient No. 4: Below 6 year old, a febrile, chest appearance of these lesions 7 days ago. The lesions are eczema. The oval nature of the lesions and angular orientation are valuable clues for diagnosis. In an uncommon type of pityriasis rosea, the rash may be concentrated in the armpits and groin or on the face, forearms, and shins. Pityriasis rosea usually begins with a single patch of pink-to-red, scaly skin, from 2–5 cm in size. This "herald patch" is usually located on the trunk, neck, or upper arms. The herald patch is followed 1–3 weeks later by the development of a widespread rash, with smaller (0.5–2 cm) oval patches of pink-to-red, scaly skin on the trunk and upper arms. The second rash forms a "Christmas tree" pattern on the back. Pityriasis rosea is a self-limited condition, meaning that it goes away on its own, typically within 6–8 weeks, without treatment. However, the rash often leaves behind patches of lighter (hypopigmented) or darker (hyperpigmented) skin, which are more obvious in darker-skinned people and may take months to return to its normal color.
