We describe the case of a middle-aged woman with a giant IDP of the breast with focal carcinoma who underwent a new technique-single axillary incision reverse-sequence endoscopic salvage resection(3,4). A review of magnetic resonance imaging, diagnostic evaluation and pathologic correlation, as well as relevant surgical approaches, is documented. Clinical practice should be alert to the possibility that giant IDP may contain a malignant component, and when excision of a giant breast mass is required, a single axillary incision with reverse-sequence endoscopic preservation of excision can provide the patient’s post-excision breast aesthetic needs through breast reconstruction techniques. Case History A left breast lump was found in a 43-year-old woman 1 year ago. 2 months ago, the lump grew rapidly and there was a bloody discharge from the left nipple with occasional localized pain. No relevant medical history or previous breast trauma was found, and there was no family history of breast cancer. Physical examination revealed a left breast mass about 15 cm in diameter, mainly involving the outer upper quadrant of the breast, with a bluish-purple coloration of the overlying skin portion, and an outward-superior deviation and deformation of the left breast (Figure 1). Differential diagnosis, investigations and treatment Laboratory tests showed elevated tumor marker CEA 23.196ng/ml. MRI of both breasts showed that the volume of the left breast had increased, and a huge irregular cystic solid mass was seen in it, measuring about 85*91*102mm, with a discernible border, the solid component was mainly located in the posterior-superior portion of the nipple, and the margins were lobulated and cauliflower-like (Figure 2), and the imaging features suggested the possibility of malignant tumors. To clarify the diagnosis, pathologic examination of the left breast mass and left axillary lymph node puncture was performed. The results of axillary lymph node examination showed lymphoid hyperplasia. Examination of the breast mass showed ductal epithelial hyperplasia with papillary hyperplasia in the focal area. Further immunohistochemistry was performed which showed IDP with ductal epithelial common type hyperplasia. (Figure 3) The patient had a strong aesthetic demand, and considering the possibility of malignancy on preoperative imaging, the patient’s consent was sought and the patient was finally treated with a trans left axillary lumpectomy with a reverse sequence method of subcutaneous resection of the left mammary gland and anterior pectoralis muscle prosthesis combined with a patch for stage I reconstruction and biopsy of the left anterior sentinel lymph node. The surgical procedure was as follows: through an invisible axillary incision in reverse anatomical order (posterior breast space-subcutaneous), the breast gland was excised, and a suitable prosthesis and biopatch were selected and placed in front of the pectoralis major muscle,and intraoperative sentinel lymph node biopsy of 3 nodes was performed on frozen section for rapid pathological examination, which showed no neoplastic lesions. Conclusion IDP is a benign, or noncancerous breast tumor, most IDPs are small, with a few lesions exceeding 5 centimeters in diameter, and IDPs greater than 10 centimeters are more rare (12,13). Papilloma diagnosed on imaging or gross needle aspiration biopsy may be diagnosed as atypical ductal growths, carcinoma in situ, and invasive carcinoma after surgical resection (14). The use of a single axillary incision for reverse-sequence endoscopic retention mastectomy gives patients access to their therapeutic and aesthetic needs by overcoming the limitations of traditional endoscopic retention mastectomy applications. Results The post-operative breast tissue underwent pathologic examination with findings of IDP with ductal epithelial exuberant hyperplasia and focal areas of atypical hyperplasia, and low-grade ductal carcinoma in situ formation (Figure 4). Post-operative diagnosis is giant IDP with localized intraductal carcinoma of the left breast (Tis Luminal B type). The patient had a good postoperative recovery, with no signs of tumor recurrence and satisfactory appearance at 1-year follow-up (Figure 5), and was treated with post-operative endocrine therapy, tamoxifen 10mg bid. Discussion IDP lesions of the breast including with or without atypical ductal hyperplasia, IDPs with carcinoma in situ or invasive carcinoma, carcinoma in situ or invasive carcinoma, pericytes carcinoma, and solid carcinoma (5,6). IDP is the most common symptom in patients with IDP, but patients usually do not have specific clinical findings before imaging, and puncture pathology testing is often inconclusive due to limited access to material, and may diagnose a benign lesion that is inadequately treated or requires a second surgical procedure (7,8,9). Single axillary incision reverse-sequence endoscopic retention resection is a safe, cheaper, and efficient surgical technique with a reliable mid-term oncologic safety profile. In suitable candidates, breast reconstruction techniques based on subpectoral implants can provide excellent cosmetic results (10,11). In our patients, transaxillary mastectomy of the breast mass was performed due to a large mass in the breast and the need for breast aesthetics. According to us, only a few cases have been reported of giant IDP of the breast with focal carcinoma and new technique-single axillary incision reverse sequence endoscopic retention resection cases. Conflict of Interest Statement The authors have no relevant financial or nonfinancial interests to disclose. Key Clinical Message Giant Intraductal papilloma (IDP) may contain a malignant component, and when excision of a giant IDP is required, a single axillary incision with reverse-sequence endoscopic preservation of excision can provide the patient’s post-excision breast aesthetic needs through breast reconstruction techniques.
