Question 37

Benign Condition of Unknown Cause: Median Rhomboid Glossitis

Answer 37

Appears as flat or slightly raised oval erythematous area in midline of dorsal tongue. Devoid of filiform papillae (smooth texture), remaining tongue surface is coated and appears raised. May be associated with chronic fungal infection by Candida Albicans

Question 38

Benign Condition of Unknown Cause: Geographic Tongue or "Migratory Glossitis"

Answer 38

Diffuse areas devoid of filiform papillae; appears as erythmatous patches surrounded by white or yellow border. NOT static, inherited, histology similar to psoriasis, exacerbated by stress, sometimes burning sensation.

Question 39

Benign Condition of Unknown Cause: Fissured Tongue

Answer 39

Dorsal tongue surface shows deep fissures or grooves that can become irritated if food debris collects. Seen in 5% population. Inherited.

Question 40

Benign Condition of Unknown Cause: Hairy Tongue

Answer 40

Increased accumulations of keratin on filiform papillae that results in white, hairy appearance. Papillae can be brown or black due to chromogenic bacteria, tobacco, foods. Temporarily reversed with tongue brushing.

Question 42
