Precursor B-cell lymphoblastic lymphoma (B-LBL) is a rare entity and primary cutaneous B-LBL is an even more uncommon diagnosis that typically affects children. A 4-year-old boy presented with a persistent rash on his left cheek for almost 2 years and was found to have primary cutaneous B-LBL. We report this case to emphasize that B-LBL should be in the differential diagnosis for an otherwise unimpressive persistent lesion in the head and neck region and review all reported pediatric cases of primary cutaneous B-LBL without extracutaneous involvement.
前体B细胞淋巴母细胞淋巴瘤（B-LBL）是一种罕见的疾病，而原发性皮肤B-LBL的诊断更为罕见，通常影响儿童。一名4岁男孩左侧脸颊出现持续皮疹近2年，被诊断为原发性皮肤B-LBL。我们报告此病例以强调，对于头颈部区域看似不严重的持续性病变，B-LBL应列入鉴别诊断，并回顾所有报道的无皮肤外受累的儿童原发性皮肤B-LBL病例。
