Summary

Pigmented subungual lesions are often mistaken for benign nevi. In a study of 1000 patients, all pigmented lesions were found to be subungual hematomas, suggesting benign nevi are rare and suspicious lesions warrant further investigation.

Area of Science:

  • Dermatology
  • Oncology
  • Podiatry

Background:

  • Distinguishing subungual hematoma from benign and malignant nevoid lesions presents a diagnostic challenge in clinical practice.
  • Subungual nevi, particularly in Caucasian populations, are infrequently encountered, necessitating careful evaluation of pigmented nail bed lesions.

Purpose of the Study:

  • To ascertain the incidence of benign subungual nevi within the general Caucasian population.
  • To evaluate the clinical presentation and diagnostic implications of pigmented subungual lesions.

Main Methods:

  • Examination of fingernails and toenails in 1000 consecutive Caucasian patients presenting for unrelated hospital complaints.
  • Clinical assessment and documentation of pigmented subungual lesions.

Main Results:

  • Eight patients (0.8%) exhibited pigmented subungual lesions.
  • All identified pigmented lesions were histopathologically confirmed as subungual hematomas, despite the absence of a reported history of trauma.
  • No benign subungual nevi were identified in the study cohort.

Conclusions:

  • Benign subungual nevi are rare in Caucasian individuals.
  • Pigmented subungual lesions, even without a history of injury, should be treated with high suspicion for malignancy until definitively proven otherwise.
  • This finding underscores the importance of thorough dermatological evaluation for all subungual pigmented lesions.
