Feedback:
Bullae are large (1.0 cm or larger in diameter) fluid-filled blisters, whereas vesicles are small (<1.0 cm in diameter). Nodules are solid marble-like lesions (>0.5 cm) that are deeper and firmer than a papule. A wheal is a somewhat irregular, relatively transient area of localized skin edema, such as a mosquito bite.
