What condition might a patient exhibit if they have swollen face, puffiness around eyes, and absence of dental complaints after gastrointestinal x-rays?

A patient displaying a swollen face, puffiness around the eyes, and no dental complaints after gastrointestinal x-rays likely indicates angioneurotic edema, also known as angioedema. This condition is characterized by rapid swelling of the deeper layers of the skin, often around sensitive areas such as the eyes and lips.

Angioneurotic edema can result from various causes, including allergic reactions or hereditary factors, but it is distinct in that it usually produces swelling without the accompanying pain or tenderness that would typically suggest a dental issue or infection. The absence of dental complaints further supports the diagnosis of angioneurotic edema, as conditions like an acute periapical abscess or acute maxillary sinusitis would typically present with localized pain or other dental-related symptoms.

In the case of infectious mononucleosis, while it can cause swelling in lymph nodes and general discomfort, the specific combination of facial puffiness and the lack of dental complaints points more clearly to angioneurotic edema as the most fitting diagnosis. Thus, the symptoms described are most consistent with angioneurotic edema.
