To report a case of ALK-positive Spitz nevus in a pediatric patient and review existing literature on the condition.
Approach:
Literature Review: The article reviews the characteristics of Spitz nevus, its benign nature, and the role of ALK gene fusions in differentiating it from malignant melanoma.
Key Findings:
The patient exhibited a large ALK-positive Spitz nevus with satellite foci and gradual enlargement.
Histopathology revealed spindle-shaped cells with positive reactions to multiple markers including ALK.
Interpretation:
Spitz nevus is a benign melanocytic lesion commonly found in children, with ALK positivity aiding in differential diagnosis from malignant melanoma.
Limitations:
The case presented atypical features that may require extended follow-up.
Conclusion:
Complete surgical excision is recommended for atypical cases, and the patient showed no recurrence after one year of follow-up.
Federal prosecutors allege that a Florida physician and research staff fabricated clinical trial records that were submitted into database systems used to evaluate investigational drugs.
