Background

Bloody nipple discharge (BND) is a rare and distressing finding in infants, although its etiology is usually benign. Diagnostic management of BND and breast lesions in children calls for an adapted approach.

Case

We present the case of an 11-month-old girl with unilateral BND and a painless breast mass. Sonographic and histologic examination identified juvenile papillomatosis of the breast.

Summary and Conclusion

Juvenile papillomatosis of the breast is a rare cause of breast lesions in young patients with specific sonographic and histologic characteristics. Because of the associated risk of malignancy, surgical excision is the preferred therapy.

幼儿乳头状瘤病：婴儿血性乳头溢液一例。

背景

尽管婴儿的病因通常是良性的，但婴儿中流血的乳头溢液（BND）是一种罕见且令人困扰的发现。儿童BND和乳腺病变的诊断管理需要一种适应性方法。

案件

我们介绍了一个单月BND和无痛乳房肿块的11个月大女孩的病例。超声检查和组织学检查可发现青少年乳头状瘤（JPB）。

总结与结论

JPB是具有特定超声和组织学特征的年轻患者乳腺病变的罕见原因。由于相关的恶性风险，手术切除是首选的治疗方法。
