摘　　要：包裹性乳头状癌是乳腺导管内乳头状癌的特殊组织学亚型,仅占所有乳腺癌的0.9%~2.0%,好发于绝经后的中老年女性。临床上常表现为乳房肿块和乳头血性溢液,易与其他乳腺良、恶性病变混淆,导致误诊或漏诊而延误诊治。报告1例以右侧乳腺炎为主要临床表现的50岁女性患者,乳腺超声提示炎症并乳腺脓肿,穿刺结果考虑炎性改变,对症治疗后症状未见缓解,手术完整切除后病理诊断为包裹性乳头状癌。对于绝经后女性且存在长期未经治疗的乳腺结节突发局部感染或脓肿时,应警惕伴乳腺包裹性乳头状癌的可能,必要时应完整切除肿物并行病理学检查以明确诊断,改善患者的预后。Encapsulated papillary carcinoma is a rare histological subtype of intraductal papillary carcinoma of the breast,accounting for only 0.9%to 2.0%of all breast cancers.It primarily occurs in postmenopausal women and typically presents clinically as breast mass or bloody nipple discharge.Due to its nonspecific presentation,encapsulated papillary carcinoma can be easily confused with benign or malignant breast conditions,often resulting in misdiagnosis or delayed treatment.We report a case of a 50-year-old female patient who presented with symptoms resembling right-sided mastitis.Breast ultrasound suggested inflammatory changes with breast abscess,and initial fine-needle aspiration suggested inflammation.However,the symptoms did not improve with symptomatic treatment.Following surgical excision,pathological diagnosis confirmed encapsulated papillary carcinoma.In postmenopausal women presenting with sudden infection or abscess in a long-standing untreated breast nodule,the possibility of underlying encapsulated papillary carcinoma should be considered.Complete surgical excision and histopathological examination are essential for definitive diagnosis and to improve patient outcomes.
