Atypical Spitz tumors are one type of the Spitzoid melanocytic lesion, characterized by one or more atypical features, and often demonstrate indeterminate biological potential. Atypical Spitz tumors pose challenges in both clinical and pathological diagnoses. Herein, we report a case of a 1-year-old Japanese girl who presented with a rapidly enlarging lesion mimicking a pyogenic granuloma. The patient was ultimately diagnosed with an atypical Spitz tumor. The challenging clinical nature and diagnostic complexity of atypical Spitz tumors underscore their significance as crucial considerations in pediatric skin tumor differential diagnosis. Consistent consideration of atypical Spitz tumors within the diagnostic framework of pediatric cutaneous neoplasms is essential for timely and accurate assessment, thereby ensuring optimal patient care.
非典型斯皮茨肿瘤是斯皮茨样黑素细胞性病变的一种类型，其特征为具有一个或多个非典型特征，并且常常表现出不确定的生物学潜能。非典型斯皮茨肿瘤在临床和病理诊断方面均带来挑战。在此，我们报告一例1岁日本女孩，其表现为一个迅速增大的病变，类似化脓性肉芽肿。该患者最终被诊断为非典型斯皮茨肿瘤。非典型斯皮茨肿瘤具有挑战性的临床特性和诊断复杂性突显了其在儿童皮肤肿瘤鉴别诊断中作为关键考量因素的重要性。在儿童皮肤肿瘤的诊断框架内持续考虑非典型斯皮茨肿瘤对于及时准确的评估至关重要，从而确保为患者提供最佳治疗。
