Clinical presentations of MBAITs. MBAITs have variable clinical presentations including pink polypoid papules (1, from shoulder of patient W-F1-IV-9), raised pink papules (2, from groin of L-F1-IV-15), and lightly pigmented papules (3, from cheek of L-F1-IV-4). These lesions were clinically difficult to distinguish from banal dermal nevi, as pictured in (4), which shows a clinically similar lesion also from the chest of the same patient pictured in (2).
