OBSERVE / REASON / EXPLAIN

Oral lesion description

Describe an oral lesion objectively before proposing a differential.

Original teaching scenario / OSCE

Your practical station

An examiner asks you to describe an oral mucosal teaching case. Present observations first, then explain what additional history and assessment you need.

Recognise and interpret

Site, distribution, surface, border, colour, size and history support a structured description.

1

Locate

State the precise anatomical site and number of lesions.

2

Describe

Record morphology and measurements without replacing observations with a diagnosis.

3

Correlate

Relate duration, symptoms and relevant history to the differential.

At the viva table

Try answering aloud, then open the suggested answer. Examiner questions vary.

01 / Is a white patch automatically one diagnosis?

No. Many conditions can have a white appearance.

02 / Why document duration?

Evolution over time affects the differential and urgency.

03 / Does absence of pain prove a lesion is harmless?

No. Important pathology can be painless.

04 / Why record an objective baseline?

It supports review and communication.
