Talon Noir in a Young Baseball Player: A Case Report.
Summary
Talon noir, or black heel, presents as asymptomatic pigmented macules on a child's foot. This condition, caused by shear-force injury, often resolves spontaneously within weeks.
Area of Science:
- Dermatology
- Pediatrics
- Sports Medicine
Background:
- Hyperpigmented lesions on the plantar surface of pediatric feet require a differential diagnosis including talon noir, acral melanoma, and verruca with thrombosis.
- Talon noir are characterized as asymptomatic brown-black pigmented macules resulting from intraepidermal hemorrhages.
Observation:
- This case report details talon noir in a young baseball player, noting an unusual distribution of plantar macules.
- The lesions were attributed to shear-force injury, common in athletes.
Findings:
- Talon noir are caused by repetitive friction and shear forces, leading to intraepidermal bleeding.
- These lesions are benign and typically resolve spontaneously within 2-3 weeks without intervention.
Implications:
- Properly fitting athletic footwear is crucial for preventing talon noir in pediatric athletes.
- Differentiating talon noir from more serious conditions like acral melanoma is essential for appropriate patient management.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
