Diabetic Foot Ulcer

Diabetic Foot Ulcer

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...

Summary

Acquired polyonychia, or split nail, can result from nail matrix division, often due to trauma. This case highlights a rare instance of a split nail developing on a thumb after childhood injury.

Area of Science:

Dermatology
Nail Biology
Surgical Pathology

Background:

Nail disorders are predominantly acquired, with congenital causes being rare.
Trauma to the nail unit frequently causes nail dystrophy or deformity.
Division of the nail matrix can lead to acquired polyonychia, commonly known as a split nail.

Observation:

A 50-year-old male presented with a split nail on his right thumb.
The condition originated from a childhood trauma to the affected digit.
Clinical examination and X-ray confirmed a well-defined split nail plate.

Findings:

The patient exhibited acquired polyonychia resulting from trauma.
Surgical intervention was recommended but declined by the patient.
