ABSTRACT
Type I hypersensitivity reactions following ingestion of peanuts and tree nuts are well characterized. Cutaneous hypersensitivity reactions are less well characterized, yet they remain the second most common reaction pattern to contact with or ingestion of such nuts. We present a case of a patient who experienced an acute vesicular cutaneous reaction after prolonged contact with pecans. This case illustrates the salient features of contact dermatitis and serves as a reminder that contact with allergenic foods can lead to hypersensitivity reactions.

Classic porokeratosis is a rare skin disease occasionally involving the oral mucosa. It is characterized by the clinically and histologically distinctive comoid lamella. This case represents a variant of Mibelli's classic porokeratosis presenting as a solitary lesion on the mucosal surface of the lower lip.
