Posttraumatic Onychoheterotopia: A Report of Two Cases

Area of Science:

• Dermatology
• Hand Surgery
• Trauma Medicine

Background:

• Ectopic nail growth is a rare condition.
• Trauma can lead to unusual nail presentations.

Purpose of the Study:

• To report a unique case of ectopic nail growth on the palmar aspect of a finger.
• To discuss the clinical presentation and management of this rare condition.

Main Methods:

• A case report of a 35-year-old male with ectopic nail growth.
• Clinical examination and patient history.
• Assessment of quality of life using the Dermatology Life Quality Index (DLQI).

Main Results:

• An asymptomatic ectopic nail developed on the palmar aspect of the middle finger 9-10 months post-trauma.
• The ectopic nail was oriented vertically and lacked normal luster.
• The patient reported no impact on quality of life (DLQI score of 0).

Conclusions:

• Ectopic nail growth can occur after significant hand trauma.
• Conservative management may be appropriate for asymptomatic cases.
• This condition, though rare, highlights the complex healing potential of nail structures.
