Agminate Spitz naevi arising on hyperpigmented patches

Area of Science:

• Dermatology
• Pediatric Dermatology
• Oncology

Background:

• Dr. Sophie Spitz established criteria in 1948 to differentiate juvenile melanoma from malignant melanoma.
• Spitz nevi, a type of melanocytic lesion, are typically benign but can be challenging to diagnose.
• Eruptive Spitz nevi have been documented on various skin pigmentation types, including normal, hypopigmented, and lightly pigmented skin.

Observation:

• Spitz nevi arising on hyperpigmented skin are exceptionally rare, with only 12 previous reports in medical literature.
• This paper details three new cases of eruptive Spitz nevi observed within a single year in a pediatric dermatology department.
• All three cases involved children and the lesions appeared on the arms.

Findings:

• The occurrence of eruptive Spitz nevi on hyperpigmented skin is exceedingly uncommon.
• The three presented cases add to the limited existing data on Spitz nevi in this specific context.
• The lesions were observed on the arms of pediatric patients.

Implications:

• Increased awareness of Spitz nevi on hyperpigmented skin is crucial for accurate diagnosis in pediatric patients.
• These findings may prompt further research into the specific characteristics and behavior of Spitz nevi in individuals with darker skin tones.
• Clinicians should consider Spitz nevi in the differential diagnosis of pigmented lesions in children, even on hyperpigmented skin.
