Summary
Ectopic geographic tongue, a common oral condition, can appear on the oral mucosa, not just the tongue. This case highlights unusual lesion locations in a patient with diabetes and blood disorders.
Area of Science:
- Oral Medicine
- Dermatology
- Pathology
Background:
- Geographic tongue (GT) is a common, benign inflammatory condition.
- Typically, GT presents as migratory erythematous patches with peripheral white/yellowish borders on the dorsal tongue.
- Ectopic presentations of GT are rare but documented.
Observation:
- This case report details a patient with type II diabetes, thrombocytopaenia, and autoimmune haemolytic anaemia.
- The patient presented with lesions clinically and histologically consistent with geographic tongue.
- These lesions were located on the floor of the mouth and cheek mucosa, rather than the tongue.
Findings:
- The findings demonstrate an unusual ectopic manifestation of geographic tongue.
- Histological examination confirmed the lesions were similar to typical geographic tongue.
- This presentation expands the known clinical spectrum of geographic tongue.
Implications:
- This case underscores the importance of considering ectopic geographic tongue in differential diagnoses for oral mucosal lesions.
- Awareness of ectopic GT is crucial for accurate diagnosis and patient management.
- Further research may explore potential triggers or associations for ectopic GT in specific patient populations.

00:49The Tongue and Taste Buds
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
