Practitioners often encounter peculiar round/oval rashes in pe-diatric patients, particularly during the warm-weather months. Most of these rashes are benign, and most are insect-related; but certain ones may be more ominous. In some regions of the country, tick bites are a year-round issue, but cases have been reported elsewhere in colder months, due to the frequent number of warm spells during the winter in which ticks may emerge. Besides, soon enough the warm months of "lemonade-time" and tick bites will be upon much of the rest of us. Thus I thought this presentation "refreshing" some aspects of particularly benign-looking rashes - with especially problematic outcomes if left untreated - would be worthwhile. As usual, these cases show that the synthesis of the history with the physical findings is critical.CASE ONE A previously healthy, white, 3-month-old girl presents to your office with a faint, concentric 3-cm ovoid rash in the posterior axillary area (see Figure 1) that started yesterday. During a 3-day family camping trip at a Kentucky state park the previous weekend, the mother noticed a small black dot under the baby's axilla, which she scraped off with much difficulty.
