“…SNB can be used for lymph node staging of ABC just as for orthotopic breast cancer [ 1 , 3 , 13 , 15 – 18 , 20 , 21 ]. The classical Sappey’s line serves as a “watershed,” defined as an imaginary line transversely connecting the umbilicus to the L2 on the back, separating the area of lymphatic drainage of the torso.…”

“…His classification is still used today because glandular tissue is subject to hormonal effects and medical conditions such as enlargement, swelling, tenderness, lactation during puberty, premenstruation and/or pregnancy, as well as development of fibroadenoma, adenoma, cysts, abscesses, mastitis, and particularly ductal carcinoma. Our case corresponds to Kajava’s class I; complete breast with nipple, areola, and glandular breast tissue all in place (also known as polymastia) [ 1 , 5 , 8 , 12 , 13 ].…”

“…The incidence of ectopic breast cancer, including the aberrant type, is low, i.e., 0.2–0.6% of all breast cancers. The most common location is the axilla (60–70%), although it can develop in other less common locations such as IMR (5–10%) and rarely in the thighs, perineum, groin, and vulva [ 3 , 13 , 15 ]. Of the 1,148 cases of primary breast cancer we encountered from 1992 to 2020, only five (0.44%) were ABC, and all four previous cases were in the axilla.…”

Accessory breast cancer in the inframammary region: a case report and review of the literature

et al. 2021

Background Although a few cases of accessory breast cancer (ABC) have been reported, most were in the axillary region. We encountered an extremely rare case of ABC in the inframammary region (IMR). Case presentation The patient was a 68-year-old postmenopausal woman who had noticed a congenital accessory nipple in her left IMR with slight, occasional discharge 20 years ago. Recently, she noticed a mass under the accessory nipple and visited a nearby clinic; fine-needle aspiration cytology of the mass revealed that it was malignant. She presented to our department 2 weeks after she had noticed the mass. Physical and imaging examinations showed an irregular tumor mass 1.7 × 1.4 × 1.0 cm in size connected to the accessory nipple beneath the left normal breast. Neither distant metastasis nor lymph node swelling was observed. Ultrasound-guided core needle biopsy revealed the mass to be invasive ductal carcinoma. We diagnosed her tumor as ABC in the left IMR; cT1cN0M0: stage IA. Curative wide resection with sentinel node biopsy was performed. Intraoperative evaluation of the frozen section revealed a hot and green ipsilateral axillary lymph node that was free from carcinoma; therefore, nodal dissection was avoided. Histopathological examination including immunochemical staining revealed that the tumor was invasive ductal carcinoma arising from the accessory breast tissue, scirrhous type, 1.7 × 1.4 × 1.0 cm in size, with a solid intraductal component. There was no lymphovascular infiltration, and the surgical margin was 1.5 cm or more. The tumor was estrogen and progesterone receptor-positive, Her2/neu-negative, and had a Ki-67 labeling index of 20%. There was no involvement of the three hot and/or green nodes. The final classification was pT1cN0(sn)M0: stage IA. Letrozole 2.5 mg/day will be administered for 5 years as adjuvant hormonal therapy. Conclusions A cutaneous and/or subcutaneous lesion except for proper breast tissue on the milk line, or mammary ridge from axilla to groin may be an accessory breast tissue. Its serial abnormalities must be worried malignant potential to ductal carcinoma which needs some imaging and pathological examinations for definitive diagnosis and appropriate treatment according to the usual orthotopic breast cancer without delay.

Carcinoma of the accessory axillary breast is uncommon, with an incidence of 0.2 to 0.6%. We report a patient whose biopsy of a suspicious lesion in the axilla present for one year revealed invasive ductal carcinoma (IDC). There was presence of breast tissue and absence of lymphoid tissue in the biopsy, suggesting a breast malignancy. Magnetic resonance mammography was suggestive of the lesion well away from the normal breast, confirming an accessory axillary breast. She was offered wide local excision of the lesion with axillary lymph node dissection and modified radical mastectomy (MRM), and she chose the latter. Her post-operative biopsy showed the involvement of all the 25 lymph nodes harvested. Any suspicious lesion in the axilla should be promptly worked up for malignancy. Accessory axillary breast carcinoma, if confirmed, can be addressed with wide local excision along with axillary lymph node dissection. However, further studies should clarify this and the outcomes.

“…Accessory Breast Tissue is the abnormal formation of breast tissue at any point along the embryogenic breast line. It is mostly seen in the axillary region and may present a restrictive pattern [3]. ESPB was chosen for anesthesia in our case with accessory breast tissue covering the axillary fossa due to its location and the patient's preference against general anesthesia.…”

ESPB that has axial and sagittal spreads allows it to be as effective as the central blocks. Although its effectiveness on postoperative thorax analgesia has been vastly reported, the number of studies on its use in combination with other blocks for sedation purposes in the management of breast surgery anesthesia is limited. We present the anesthetic management of a patient for accessory breast tissue surgery by using ESPB block from T1. We observed that the effect of ESPB on skin incision and skin-related tissue retractions was limited while postoperative pain control was sufficiently managed by the skin infiltration with ESPB.
