[Internal medicine, seen from the mouth].

Area of Science:

• Oral Medicine
• Internal Medicine
• Dermatology

Background:

• The oral cavity is frequently affected by various systemic diseases.
• Oral manifestations can serve as crucial indicators of underlying health conditions.
• Systemic diseases often present with distinct signs within the oral cavity.

Purpose of the Study:

• To highlight the importance of oral semiology in internal medicine.
• To present five distinct oral lesions as indicators of systemic conditions.
• To emphasize the role of differential diagnosis in identifying severe diseases from oral findings.

Main Methods:

• Presentation of five clinical cases with specific oral manifestations.
• Detailed description of oral semiology findings: strawberry tongue, ulceration, labial lesion, gingival hyperplasia, gingival hyperpigmentation.
• Discussion of differential diagnoses for each presented oral condition.

Main Results:

• Specific oral signs, including strawberry tongue, ulcerations, labial lesions, gingival hyperplasia, and hyperpigmentation, were illustrated.
• These oral findings were linked to potential underlying systemic diseases.
• The study demonstrates the diagnostic value of observing these oral signs.

Conclusions:

• Oral semiology is a vital tool for internists to detect systemic diseases.
• Prompt recognition and differential diagnosis of oral lesions can lead to the identification of severe underlying conditions.
• A thorough oral examination should be an integral part of a comprehensive medical assessment.
