Nipple adenoma in prepubescent boy：a case report and review

Abstract Background：Nipple adenoma is a rare benign nipple tumor that is seldom seen in males and can be challenging to differentiate from Paget's disease. Case report：We report the case of a boy with nipple adenoma who was initially misdiagnosed with Syringocystadenoma papilliferum combined with a tubular apocrine adenoma. Six months post-diagnosis, a nipple-areolar resection was conducted, followed by a purse-string suture technique to restore and reshape the nipple's appearance. Histopathological examination confirmed the diagnosis of nipple adenoma. Conclusion：Nipple adenomas often prove difficult to alleviate without surgical intervention; surgical excision is deemed the gold standard for treatment. It is vital to establish a clear pathological diagnosis for nipple adenomas, as they are benign tumors, to prevent unnecessary overtreatment.
