Noninvasive Real-Time Assessment of Nipple-Areola Complex Perfusion Using Laser Speckle Contrast Imaging in Direct-to-Implant Breast Reconstruction.

BACKGROUND: Nipple-areola complex (NAC) necrosis is a major complication for breast reconstruction after nipple-sparing mastectomy. Although intraoperative indocyanine green angiography helps to assess the viability of tissue, the imaging could be conservative which may lead to aggressive resection. The plastic surgeons are eager to know the perfusion changes of NAC throughout the perioperative period. METHODS: In this prospective cohort study, the authors enrolled patients who underwent NSM and immediate direct-to-implant breast reconstruction. All patients underwent laser speckle contrast imaging before surgery, immediately after mastectomy, after implant placement, and 24 h and 72 h after surgery. RESULTS: A total of 94 breasts were analyzed, including 64 breasts healed with viable NAC and 30 breasts with NAC necrosis. In viable NACs, the average blood supply decreased to 56% after NSM and 42% after reconstruction, then recovered to 68% and 80% at 24-h and 72-h post-operation. In necrotic NACs, the average blood supply decreased to 33% after NSM and 24% after reconstruction, and partial perfusion recovery was also recorded at 24-h (31%) and 72-h (37%) post-operation. The cutoff value for predicting NAC viability is 40% after NSM and 25% after implant placement. CONCLUSIONS: The study quantified the NAC perfusion changes during the perioperative period. NAC perfusion decreased significantly after NSM and would be the lowest after the end of breast reconstruction. Viable NACs displayed more perfusion during the operation and showed significant nipple revascularization after breast reconstruction.

Aeromonas hydrophila Infection following Leech Therapy for the Treatment of Nipple-Areola Complex Congestion after Breast Reduction: A Case Report.

Several strategies for the management of venous congestion of the nipple-areola complex (NAC) after reduction mammaplasty have been proposed. Among these, hirudotherapy represents an ancient but still effective method, even though the risk of infections related to leeches should be considered. We report a peculiar case of breast infection and sepsis after leech therapy in a patient who underwent a reduction mammaplasty. A prompt surgical debridement of the wounds and necrotic tissues associated with targeted antibiotic therapy led to a fast improvement of clinical conditions, and partial preservation of the NAC was obtained. Accurate knowledge of the clinical presentation of soft tissue infections related to leeching allows for an early diagnosis and would serve as a warning for surgeons who approach such breast cosmetic procedures.

Positive Nipple Margins in Nipple-Sparing Mastectomy: Management of Nipples Containing Cancer or Atypia.

BACKGROUND: Nipple-sparing mastectomy (NSM) is an oncologically safe approach for breast cancer treatment and prevention; however, there are little long-term data to guide management for patients whose nipple margins contain tumor or atypia. METHODS: NSM patients with tumor or atypia in their nipple margin were identified from a prospectively maintained, single-institution database of consecutive NSMs. Patient and tumor characteristics, treatment, recurrence, and survival data were assessed. RESULTS: A total of 3158 NSMs were performed from June 2007 to August 2019. Nipple margins contained tumor in 117 (3.7%) NSMs and atypia only in 164 (5.2%) NSMs. Among 117 nipple margins that contained tumor, 34 (29%) margins contained invasive cancer, 80 (68%) contained ductal carcinoma in situ only, and 3 (3%) contained lymphatic vessel invasion only. Management included nipple-only excision in 67 (57%) breasts, nipple-areola complex excision in 35 (30%) breasts, and no excision in 15 (13%) breasts. Only 23 (24%) excised nipples contained residual tumor. At 67 months median follow-up, there were 2 (1.8%) recurrences in areolar or peri-areolar skin, both in patients with nipple-only excision. Among 164 nipple margins containing only atypia, 154 (94%) nipples were retained. At 60 months median follow-up, no patient with atypia alone had a nipple or areola recurrence. CONCLUSIONS: Nipple excision is effective management for nipple margins containing tumor. No intervention is required for nipple margins containing only atypia. Our results support broad eligibility for NSM with careful nipple margin assessment.

Successful correction of inverted nipple using silicone implants: A pioneering surgical approach.

Inverted nipples are commonly observed and can lead to challenges in breastfeeding, sexual experiences, and dissatisfaction with one's physical appearance. Currently, there is a lack of consensus on the optimal treatment approach. The use of a smooth silicone implant to reconstruct the nipple-areola complex in post-mastectomy breast reconstruction has recently been proposed. This study presents the first case using this approach in a patient with a grade II inverted nipple who previously failed conventional reconstructive surgical treatment.

Immediate Partial Breast and Nipple-Areola Complex Reconstruction Using a Superficial Circumflex Iliac Artery Perforator Flap.

The superficial circumflex iliac artery perforator (SCIP) flap is a versatile flap that has been described for various applications, mostly for lower extremity coverage and head and neck reconstructions. However, there are few publications reporting its use for breast reconstruction, mainly because of its low volume availability. In this article, we present the case of a patient who successfully underwent a partial breast and immediate nipple-areola complex (NAC) reconstruction with an SCIP flap. She had been previously reconstructed with an implant after a nipple-sparing mastectomy, but the NAC turned out to be involved with cancer needing further resection. Our goal with this article, is to introduce a novel concept for addressing partial breast and NAC reconstruction and mostly, to illustrate the importance of an adaptable surgical plan based on every individual case emphasizing the versality of microsurgery for breast cancer reconstruction.

Marking the nipple-areola complex in mastopexy and reduction mammoplasty: a geometrical method.

Mastopexy and reduction mammoplasty are well-established procedures used to address ptotic and hypertrophic breasts. A variety of methods have been described in the literature for managing the three main aspects of these procedures: skin excess, parenchyma, and the nipple-areola complex (NAC). Among these techniques, several have specifically addressed the markings of the NAC in procedures involving a preoperatively established NAC position. While many of these have proven effective over time, the literature lacks standardized and reproducible methods. In this paper, we introduce, step-by-step, a novel approach based on geometrical principles to address this limitation. This method involves the simple process of drawing two hemi circumferences on the vertical limbs of the skin resection pattern, which are commonly marked using the Bisemberg maneuver or similar techniques. The method we introduce is adaptable to virtually all NAC pedicles. Furthermore, as exemplified in the accompanying video, it can be incorporated to most skin resection patterns with a preoperatively defined NAC position. The clinical application, as evidenced in the case reported, appears to be promising. Although it has some limitations, this procedure shows the potential to reduce inaccuracy by minimizing variability factors. As a result, even inexperienced surgeons can achieve precise markings.

Successful treatment of Bowen's Disease in the nipple-areola complex with a combination of photodynamic therapy and cryotherapy-A case report.

Photodynamic therapy (PDT) is a non-invasive, effective treatment for superficial skin conditions, offering superior cosmetic outcomes compared with traditional therapies. Bowen's disease (BD) of the nipple-areola complex (NAC) is rare and thus, lacks a standardized treatment approach. This report details the case of a 48-year-old woman who was successfully treated for BD of the NAC using PDT. Over a follow-up period of 30 months, there was no evidence of disease recurrence, underscoring the potential of PDT as a viable treatment option for this rare manifestation of BD.

Tattooing to reconstruct Nipple-Areola Complex after oncological breast surgery: a scoping review.

PURPOSE: The dermopigmentation of the Nipple-Areola Complex (NAC) is a safe non-surgical reconstruction technique that can restore psychophysical integrity, representing the final step after oncological surgery. This scoping review aims to identify and synthesize the literature focused on medical tattooing for NAC reconstruction in women who underwent breast reconstruction after cancer surgery. Competence and training, outcomes and organizational aspects were assessed as specific outcomes. METHODS: The Joanna Briggs Institute (JBI) methodology for scoping reviews was followed. MEDLINE, Embase, Cochrane Library, Clinical Key, Scopus and Cinahl databases were consulted. After title (N = 54) and abstract (N = 39) screening and full-text review (N = 18), articles that met eligibility criteria were analyzed, critically apprised and narratively synthesized. RESULTS: 13 articles were analysed, with full texts (N = 11) and only abstract (N = 2). The overall quality of the literature (N observational studies = 11; N pilot experimental studies = 2) is weak. Nurses were the professionals mostly involved (N = 6), then medical staff (N = 4) and tattoo artists (N = 2). The professional training is poorly described in 6 papers. The most frequently assessed outcome was the satisfaction rate (N = 8). One study explored aspects of quality of life with a validated questionnaire. The management of these services resulted variable. Nurse-led services were implemented in 2 studies. CONCLUSION: Despite methodological weaknesses, NAC tattooing research is relevant because it helps women redefine their identity after demolitive cancer treatments. Further research on processes and outcomes is needed.

Is free nipple grafting necessary in patients undergoing reduction mammoplasty for gigantomastia? A systematic review and meta-analysis.

BACKGROUND: Gigantomastia is a debilitating condition characterised by an excessive breast tissue growth impacting patients' quality of life. Surgically treatment options include the limited-length pedicle (LP) technique with free nipple grafting (FNG) and the elongated pedicle (EP) technique, which maintains continuity of the nipple-areola complex (NAC). Initially, despite the less satisfactory aesthetic outcome, FNG was preferred to treat hypertrophic breasts requiring resections over 1000 g of parenchymal and adipose tissue, due to concerns about NAC perfusion. Recently, many studies have questioned this indication. The aim of this study was therefore to evaluate the safety of the NAC-carrying EP technique in patients with gigantomastia eventually challenging the need for FNG. METHODS: A literature search using PubMed and Cochrane databases was performed, including studies describing the outcome of EP technique for resection exceeding 1000 g of breast tissue. Thereby, a meta-analysis was conducted to evaluate the rate of NAC necrosis, whereas a descriptive statistic was applied to assess all other surgery-associated complications. RESULTS: Twenty-five studies, encompassing 1355 patients (2656 breasts), were included. EP demonstrated an extremely low rate of NAC necrosis. Moreover, the analysis demonstrated a low rate of ischaemia-independent complications and a very high probability of maintaining NAC-sensation equal to the preoperative state. CONCLUSION: Current evidence indicates that the EP technique should be the preferred surgical method to treat gigantomastia with or without massive ptosis whenever indicated. It has proven to be safe. Furthermore, it yields superior aesthetic and functional outcomes, including breast feeding and preservation of NAC-sensation compared to the LP technique.

Nipple-areola complex prosthesis as a new arsenal for breast reconstruction.

Nipple and areola complex (NAC) recreating is primordial to achieve a complete breast reconstruction. Some patients would not benefit or choose to undergo surgical or tattoo NAC reconstruction. Recently, innovative NAC silicone prostheses have been developed that are applied over the skin and come in various shapes, sizes, and colors to match different NAC tones and sizes. Our prospective study aims to evaluate for the first time, to our knowledge, the safety of these prostheses and patients' and surgeons' satisfaction using a 30-day survey. Twenty patients using these NAC prostheses after unilateral breast reconstruction postmastectomy with NAC excision were included. All patients except one (95%) were satisfied/very satisfied with the aspect and symmetry of NAC prostheses compared with native contralateral NAC. All patients were more/much more satisfied with their body image and self-esteem using the NAC prostheses. Except for 2 (90%), no participant presented any skin reaction, infection, or erosion. Most patients (68.75%) used the prosthesis every day, and others-occasionally. All participants stated they would recommend these prostheses to other women as a temporary or definitive solution. With these promising results demonstrating a high safety and satisfaction rate, we are confident that this simple, safe, noninvasive, and cost-effective device should be proposed to all patients to improve the management of breast reconstruction and offer body integrity to patients. Health insurance should consider reimbursement for these prostheses in patients after mastectomy or with NAC deformation after trauma, surgery, or congenital.

Factors influencing the shape, size, symmetry and scar of the nipple-areola complex after bilateral reduction mammoplasty.

BACKGROUND: Asymmetry and scar formation of the nipple-areola complex (NAC) after reduction mammoplasty with periareolar suture are common complications and can significantly affect patient satisfaction. OBJECTIVE: The aim of this study was to investigate possible procedure-specific influencing factors on asymmetry and shape disturbances of the nipple-areola complex to optimize postoperative outcome and thus improve patient satisfaction. METHODS: 78 patients were followed-up after a 5-year period as part of a retrospective cohort study. Objective parameters as areolar diameter, symmetry, scar patterns, dimensions of the breast, and anthropometric measurements were recorded. All patients underwent surgery according to an established treatment algorithm depending on the preoperative measurements. Follow up was 1 week, 6 week, 6 months and 3 years postoperatively. RESULTS: The periareolar suture-technique significantly influenced the symmetry and shape of the NAC. Compared to the intraoperative determined diameter and the postoperative diameter, the net-suture technique showed the highest NAC symmetry and minimal divergence. Patients who underwent Hall-Findlay mammoplasty showed significantly higher rates of asymmetry and deformity of the NAC with teardrop formation in comparison to Lejour mammoplasty. Scar formation was affected by periareolar ruffle formation especially after purse string suture. CONCLUSIONS: Regardless of what reduction mammoplasty techniques and periareolar suturing-technique are used, a tension-free suture of the NAC is crucial for shape, symmetry and scar formation. The net suture technique resulted in significantly higher symmetry of the NAC.

Utilidad de la fotografía térmica como herramienta predictora de compromiso vascular del complejo areola-pezón / Utility of thermal photography as a predicting tool of vascular involvement of nippel-areolar complex

Introducción y objetivo: La viabilidad del complejo areola pezón (CAP) es un aspecto de vital importancia en cirugía mamaria. En estudios previos presentamos, con el uso de la mamografía 3D, que la revascularización de los CAP tras mastopexia no es ad-integrum y que existen patrones vasculares distintos en algunas pacientes después de ser sometidas a cirugía mamaria. Hay métodos para evaluar la circulación de los tejidos, no solo antes de la cirugía, sino durante el intraoperatorio, como son: la colorimetría, la indocianina verde y la termografía. Nuestro objetivo es presentar el uso de la termografía como predictor del compromiso vascular de los CAP durante la mastopexia. Material y método: Estudio prospectivo observacional en 37 pacientes (74 mamas) sometidas a mastopexia en las que realizamos mediciones de temperatura con cámara térmica portátil (Flirone pro®, modelo 435-0004-03) para teléfono inteligente (Apple, I-phone® 12, versión 16.1.1). Evaluamos resultados en cuanto a diferenciales de temperatura en 3 etapas de cirugía mamaria: inicial, intermedia y final. Resultados: El promedio de temperatura entre inicial y final de las pacientes con signos clínicos de compromiso vascular de los CAP fue superior a 4 grados de diferencial. En el resto de las pacientes, en las que los CAP no presentaron signos clínicos de cambios de flujo sanguíneo, el diferencial entre la temperatura inicial y la final fue menor de 3.1 grados. Conclusiones: Mantenerse a la vanguardia en la seguridad de la especialidad nos compromete a disponer de procedimientos seguros para nuestros pacientes. En nuestra experiencia, la termografía puede servir como herramienta predictora del compromiso vascular del C.A.P durante la cirugía mamaria.(AU)

Background and objective: The viability of the nipple areola complex is a vitally important aspect in breast surgery. In previous studies, with the use of 3D mammography, we presented that the revascularization of the NIC after mastopexy is not ad-integrum and that there are different vascular patterns in some patients after undergoing breast surgery. There are methods to evaluate tissue circulation, not only before surgery, but also during the intraoperative period, such as: colorimetry, indocyanine green, and thermography. Our objective is to present the use of thermography as a predictor of vascular compromise of the nipple-areola complexNIC during mastopexy. Methods: A prospective and observational study was carried out in 37 patients (74 breasts) who underwent mastopexies. Temperature was obtained using the Flir one pro® model 435-0004-03 portable thermal camera for smartphones (Apple® smartphone,I-phone12 version 16.1.1, evaluating temperature differentials in 3 stages of breast surgery: initial, intermediate and final. Results: The average temperature between initial and final in patients with clinical signs of vascular compromise of the nipple-areola complex was greater than 4 degrees. Rest of patients, with nipple-areola complex without clinical signs of blood flow changes, a differential between the initial and final temperature of <3.1 degrees was found. Conclusions: In our experience, thermography can serve as a predictive tool of vascular compromise of the nipple-areola complex during breast surgery.(AU)

Superomedial-Posterior Pedicle-Based Reduction Mammaplasty: Evaluation of Effectiveness and BREAST-Q Outcomes of a Rapid and Safer Technique.

INTRODUCTION: Breast hypertrophy, a common pathological condition, often requires surgical intervention to alleviate musculoskeletal pain and improve patients' quality of life. Various techniques have been developed for breast reduction, each with its own advantages and complications. The primary aim of this study is to evaluate the efficacy, safety, and patient-reported outcomes of the authors technique: the Superomedial-Posterior Pedicle-Based Reduction Mammaplasty. MATERIAL AND METHODS: A prospective study was conducted on 912 patients who underwent breast reduction surgery between November 2012 and July 2020. The surgical technique involved preserving all glandular tissue from the areola to the pectoralis major muscle using the superomedial-posterior pedicle. The patients' demographic data, operative details, complications, breast-related quality of life (measured using the Breast-Q questionnaire), and nipple-areola complex sensitivity were analyzed. RESULTS: The average operative time was 62.12 ± 10.3 minutes. Complications included minor wound dehiscence (4.05%) and hematoma (1.2%), with no cases of nipple-areola complex necrosis. Nipple-areola sensitivity was fully restored in all patients at the 2-year follow-up. Patient satisfaction with the procedure was high with a statistically significant difference observed between pre- and postoperative scores (p < 0.001) of the Breast-Q questionnaire. CONCLUSION: Authors technique offers reliable vascularization and innervation of the nipple-areola complex and achieves satisfactory aesthetic outcomes. It is associated with shorter operative times compared to other techniques reported in the literature. The Superomedial-Posterior Pedicle-Based Reduction Mammaplasty represents a safe and effective method for breast reduction surgery, providing significant benefits to patients with breast hypertrophy.

A Nomogram Based on Conventional and Contrast-Enhanced Ultrasound for Pre-operative Prediction of Nipple-Areola Complex Involvement in Breast Cancer: A Prospective Study.

OBJECTIVE: Accurately predicting nipple-areola complex (NAC) involvement in breast cancer is essential for identifying eligible patients for a nipple-sparing mastectomy. This study was aimed at developing a pre-operative nomogram for NAC involvement in breast cancer using conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS). METHODS: All patients with primary breast cancer confirmed by pre-operative biopsy underwent US and CEUS examinations. Post-operative pathology was used as the gold standard in assessing NAC involvement. Lasso regression was used to select the predictors most associated with NAC involvement. A nomogram was constructed to calculate the diagnostic efficacy. The data were internally verified with 500 bootstrapped replications, and a calibration curve was generated to validate the predictive capability. RESULTS: Seventy-six patients with primary breast cancer were included in this study, which included 16 patients (21.1%) with NAC involvement and 60 patients (78.9%) without NAC involvement. Among the 23 features of US and CEUS, Lasso regression selected one US feature and two CEUS features, namely, ductal echo extending from the lesion, ductal enhancement extending to the nipple and focal nipple enhancement. A nomogram was constructed, and the results revealed that the area under the curve, sensitivity, specificity and accuracy were 0.891, 81.3%, 86.7% and 85.5%, respectively. The calibration curve exhibited good consistency between the predicted probability and the actual probability. CONCLUSION: The nomogram developed based on US and CEUS had good performance in predicting NAC involvement in breast cancer before surgery, which may facilitate the selection of suitable patients for NAC preservation with greater oncological safety.

Factors associated with alteration of nipple or skin sensation and impact of duration of time following nipple-sparing mastectomy (NSM): an analysis of 460 cases with comparison of conventional versus endoscopic- or robotic-assisted NSM.

BACKGROUND: The current study aims to evaluate the nipple and skin sensation following nipple-sparing mastectomy (NSM) and identify patient-, surgical-, or treatment-related factors affecting nipple or skin sensation in this cohort. METHODS: Patients who received NSM with postoperative nipple and skin sensation test evaluation at a single institution over the past 10 years were retrospectively retrieved from a prospectively collected breast cancer surgery database. RESULTS: A total of 460 NSM procedures were included in this current study, with the mean age of 48.3 ± 9.1. Three-hundred eighty-three (83.3%) patients had breast reconstructions. One-hundred seventy-four (37.8%) received conventional NSM (C-NSM), 195 (42.4%) endoscopic-assisted NSM (E-NSM), and 91 (19.8%) robotic-assisted NSM (R-NSM) procedures. For nipple sensation assessment, 15 (3.3%) were grade 0, 83 (18.2%) grade I, 229 (49.7%) grade II, and 133 (28.9%) grade III (normal sensation), respectively, with mean grade score of 2.1 ± 0.7. The preserved (grade III) nipple sensation rate was 36.2% (63/174) in the C-NSM group, 26.7% (52/195) in the E-NSM group, and 19.7% (18/91) in the R-NSM group (P = 0.06). The "time since surgery to last evaluation" was significantly longer in the C-NSM group (45.6 ± 34 months) or E-NSM group (44.7 ± 35.8 months) as compared to R-NSM group (31.8 ± 16 months, P < 0.01). In multivariate analysis, peri-areolar incision showed higher grade of nipple sensation (OR: 2.1, P = 0.02) compared to upper outer quadrant incision, and longer follow-up time post-NSM showed significant improvement of nipple or skin sensation (> 60 months vs. ≦ 12 months: nipple odds ratio (OR) = 5.75, P < 0.01; skin, OR = 1.97, P < 0.05). CONCLUSION: Our current analysis showed some factors to be related to postoperative nipple or skin sensation, and longer "time after surgery" was associated with significant improvement of nipple and skin sensation in patients who received NSM, regardless of the surgical approaches. SYNOPSIS: Our current analysis showed a significant portion of patients with decrease or loss of nipple or skin sensation after nipple-sparing mastectomy (NSM). Several factors associated with preserved nipple or skin sensation were identified, including age, surgical methods, surgical wound location, and association of time from surgery showing that improvement of partial nipple or skin sensation was evident after a longer follow-up.

Mamoplastia de reducción y medialización del complejo areola-pezón en paciente acondroplásica con gigantomastia. Caso clínico / Reduction mammoplasty and nipple medialization in achondroplasic patient with gigantomastia. Case report

La acondroplasia es una enfermedad genética rara que representa la forma más común de enanismo de extremidades cortas. Existen pocos casos reportados de gigantomastia y subsecuente cirugía mamaria en esta población. Presentamos el caso de una paciente con acondroplasia, gigantomastia y medialización de pezón que requirió mamoplastia reductora y reposición de complejo areola pezón (CAP). Se utilizó la técnica de T invertida con pedículo inferior. La planeación quirúrgica y el correcto marcaje en pacientes acondroplásicos son pasos importantes para una cirugía exitosa teniendo en cuenta que las referencias anatómicas habituales no son guías confiables para un posicionamiento ideal de la mama en el tórax o del CAP en la mama. (AU)

Achondroplasia is a rare genetic disease representing the most common form of short-limb dwarfism, and there are a few case reports of gigantomastia and subsequent breast surgery in this patient population. We present the case of a patient with achondroplasia, gigantomastia and nipple medialization who required a reduction mammaplasty and reposition of the nipple areola complex (NAC). An inverted T technique with an inferior pedicle was used. Surgical planning and correct marking in achondroplasic patients are important steps for a successful surgery considering that common anatomical landmarks are not a reliable guide for ideally positioning the breast on the thoracic wall or the NAC on the breast.

Nipple Sparing Goldilocks Mastectomy, A New Modification of the Original Technique.

Objective: Although Goldilocks mastectomy offers good aesthetic outcomes. Removal of the nipple-areolar complex (NAC) often has a negative psychological impact. The objective of this study was to assess the feasibility and esthetic outcome of this technique with salvage of the NAC using a dermal pedicle. Materials and Methods: The study included female patients suffering from breast carcinoma with large and or ptotic breast. Patients were offered Goldilocks mastectomy. Those who were unfit for anesthesia, those with locally advanced or metastatic disease or those refusing the procedure were excluded. Results: Fifteen female patients (18 breasts) with a mean age of 51.6 years underwent Goldilocks breast reconstruction with a trial of NAC preservation. The mean body mass index was 39.1 kg/m2. More than half (56%) were cup C, while 44% were cup D. Seven cases (46.7%) showed grade II ptosis and 8 (53.3%) were grade III. The mean operative time was 168 minutes (range 130-240 minutes). NAC ischemic changes were noted in five cases; two (11%) were partial while three (17%) were total. Two cases (11%) suffered from flap loss and one of them was total. No locoregional recurrence or distant metastases were observed. Conclusion: The Goldilocks mastectomy with nipple preservation is an appealing and feasible option for a certain group of patients who have large-sized and/or ptotic breasts. Nevertheless, it is a time-consuming technique with relatively higher rates of flap and NAC complications. Further, studies are required with a larger number of cases and longer follow-up.

How to accurately preoperative screen nipple-sparing mastectomy candidate-a nomogram for predicting nipple-areola complex involvement risk in breast cancer patients.

BACKGROUND: Nipple-sparing mastectomy (NSM) offers superior cosmetic outcomes and has been gaining wide acceptance. It has always been difficult to objectively quantify the risk of nipple-areola complex involvement (NACi). The goal was to develop a prediction model for clinical application. METHODS: Patients who had a total mastectomy (TM) between January 2016 and January 2020 at a single institute formed the development cohort (n = 578) and those who had NSM + immediate breast reconstruction (IBR) between January 2020 and January 2021 formed the validation cohort (n = 112). The prediction model was developed using univariate and multivariate logistic regression studies. Based on NACi risk variables identified in the development cohort, a nomogram was created and evaluated in the validation cohort. Meanwhile, stratified analysis was performed based on the model's risk levels and was combined with intraoperative frozen pathology (IFP) to optimize the model. RESULTS: Tumor central location, clinical tumor size (CTS) > 4.0 cm, tumor-nipple distance (TND) ≤ 1.0 cm, clinical nodal status positive (cN +), and KI-67 ≥ 20% were revealed to be good predictive indicators for NACi. A nomogram based on these major clinicopathologic variables was employed to quantify preoperative NACi risk. The accuracy was verified internally and externally. The diagnostic accuracy of IFP was 92.9%, sensitivity was 64.3%, and specificity was 96.9% in the validation group. Stratified analysis was then performed based on model risk. The diagnostic accuracy rates of IFP and NACiPM in low-risk, intermediate-risk, and high-risk respectively were 96.0%, 93.3%, 83.9%, 61.3%, 66.7%, and 83.3%. CONCLUSION: We created a visual nomogram to predict NACi risk in breast cancer patients. The NACiPM can be used to distinguish the low, intermediate, and high risk of NAC before surgery. Combined with IFP, we can develop a decision-making system for the implementation of NSM.

Basosquamous Cell Carcinoma of the Nipple-Areola Complex-Report of a Case.

Basosquamous cell carcinoma (BSCC) is a rare malignancy usually arising on sun-exposed areas of the skin. BSCC is described as a rare variant of Basal cell carcinoma (BCC) which shows clinical and microscopic features of both BCC and of Squamous cell carcinoma (SCC). We report the case of a 70-year-old male with a cutaneous lesion of the nipple-areola complex (NAC); to the best of our knowledge, this is the first ever reported patient with BSCC in this area. The lesion had a fast growth, but, due to the COVID19 crisis, the patient only came to our observation one year after onset of this condition. Physical examination showed a bleeding red ulcerated lesion that involved the NAC, measuring 27 mm × 20 mm. Biopsy showed a BSCC. Pre-operative breast ultrasound scan, mammogram and MRI were all performed before surgery, which consisted of simple mastectomy and sentinel lymph-node biopsy. The patient was discharged home on the 4th post-operative day, and at 18-month follow-up there are no signs or clinical evidence of local recurrence or metastases. Diagnosis of BSCC of the nipple-areola complex requires high index of suspicion and a thorough differential diagnosis, management, and suitable radical treatment due to well described high rates of recurrence and of metastases. Differential diagnosis with similar lesions (e.g., Paget's disease, Bowen's disease, BCC, and SCC) should also be taken into account.
