Talon Noir: A Case Report and Literature Review

Area of Science:

• Dermatology
• Podiatry
• Sports Medicine

Background:

• Talon noir is a common, benign skin condition affecting the feet.
• It is frequently observed in young athletes and individuals engaged in activities like mountain climbing.
• The condition is characterized by asymptomatic presentation and self-limiting nature.

Observation:

• A case of talon noir was observed in an elderly female patient.
• Clinically, the presentation mimicked acral melanoma, a type of skin cancer.
• This unusual presentation prompted further investigation.

Findings:

• Histological examination revealed characteristic intraepidermal hemorrhage and fluid collection.
• These findings are consistent with shearing forces, the typical etiology of talon noir.
• The biopsy confirmed the diagnosis, differentiating it from melanoma.

Implications:

• This case expands the known demographic for talon noir, including elderly individuals.
• It underscores the importance of biopsy in differentiating talon noir from potentially malignant lesions.
• Highlights the need for clinical vigilance, even in seemingly straightforward dermatological conditions.
