Question

A patient presents to the clinic with the lesion given in the image. He had a traumatic injury to the chest one year ago. What is the most likely diagnosis?

• A. Hemangioma
• B. Hypertrophic scar
• C. Keloid
• D. neurofibroma

Answer 1

The Correct Option is C

The case presents with a lesion following a traumatic chest injury one year ago. To identify the most likely diagnosis, let us understand the characteristics of each condition:

• Hemangioma: Typically presents at birth or shortly thereafter, not usually associated with trauma.
• Hypertrophic Scar: Raised, red scars that remain within the boundaries of the original wound, often developing shortly after injury.
• Keloid: Raised, thick, irregular scar tissue that extends beyond the original wound boundary. Often develops months to years after injury.
• Neurofibroma: Usually presents as soft, fleshy lesions associated with nerves, not commonly linked to trauma.

Given the history of a traumatic injury and the development of a lesion that may exceed the wound's original boundaries, the most likely diagnosis is a Keloid. Unlike hypertrophic scars, keloids are known for growing beyond the original site of skin damage, often occurring long after the inciting trauma.

Condition	Characteristics
Hemangioma	Common in infancy
Hypertrophic Scar	Confined, early formation
Keloid	Extends beyond wound, late formation
Neurofibroma	Associated with nerve fibers

Therefore, given the patient's history and lesion behavior, the likely diagnosis is Keloid.
