Oncological Outcomes of Nipple-Sparing Mastectomy in an Unselected Population Evaluated in a Single Center / Desfechos oncológicos da mastectomia poupadora do complexo areolo-mamilar em uma população não selecionada avaliada em um único centro

Abstract Objective Nipple-sparing mastectomy (NSM) has been traditionally used in selected cases with tumor-to-nipple distance > 2 cm and negative frozen section of the base of the nipple. Recommending NSM in unselected populations remains controversial. The present study evaluated the oncological outcomes of patients submitted to NSM in an unselected population seen at a single center. Methods This retrospective cohort study included unselected patients with invasive carcinoma or ductal carcinoma in situ (DCIS) who underwent NSM in 2010 to 2020. The endpoints were locoregional recurrence, disease-free survival (DFS), and overall survival (OS), irrespective of tumor size or tumor-to-nipple distance. Results Seventy-six patients (mean age 46.1 years) (58 invasive carcinomas/18 DCIS) were included. The most invasive carcinomas were hormone-positive (60%) (HER2 overexpression: 24%; triple-negative: 16%), while 39% of DCIS were high-grade. Invasive carcinomas were T2 in 66% of cases, with axillary metastases in 38%. Surgical margins were all negative. All patients with invasive carcinoma received systemic treatment and 38% underwent radiotherapy. After a mean of 34.8 months, 3 patients with invasive carcinoma (5.1%) and 1 with DCIS (5.5%) had local recurrence. Two patients had distant metastasis and died during follow-up. The 5-year OS and DFS rates for invasive carcinoma were 98% and 83%, respectively. Conclusion In unselected cases, the 5-year oncological outcomes following NSM were found to be acceptable and comparable to previous reports. Further studies are required.

Resumo Objetivo A mastectomia poupadora do complexo areolo-mamilar (MPM) tem sido tradicionalmente utilizada em casos selecionados com distância tumor-mamilo > 2 cm e biópsia de congelação da base do mamilo negativa. Recomendar MPM em populações não selecionadas continua controverso. Este estudo avaliou os resultados oncológicos de pacientes submetidas à MPM em uma população não selecionada atendida em um único centro. Métodos Coorte retrospectivo incluindo pacientes não selecionadas com carcinoma invasivo ou carcinoma ductal in situ (CDIS) submetidas à MPM entre 2010 e 2020. Os desfechos incluíram: recorrência locorregional, sobrevida livre de doença (SLD) e sobrevida global (SG), independentemente do tamanho do tumor ou da distância tumor-mamilo. Resultados Setenta e seis pacientes (média: 46,1 anos de idade) (58 carcinomas invasivos/18 CDIS) foram incluídas. A maioria dos carcinomas invasivos era hormônio-positivo (60%) (superexpressão de HER2: 24%; triplo-negativo: 16%), enquanto 39% dos CDIS eram de alto grau histológico. Os carcinomas invasivos foram T2 em 66% dos casos, com metástases axilares em 38%. As margens cirúrgicas foram todas negativas. Todas as pacientes com carcinoma invasivo receberam tratamento sistêmico e 38% receberam radioterapia. Após um período médio de 34,8 meses, 3 pacientes com carcinoma invasivo (5,1%) e 1 com CDIS (5,5%) apresentaram recidiva local. Durante o acompanhamento, duas pacientes tiveram metástase à distância e vieram a óbito. As taxas de SG e SLD aos 5 anos para carcinoma invasivo foram de 98% e 83%, respectivamente. Conclusão Em casos não selecionados, os resultados oncológicos de 5 anos após MPM foram considerados aceitáveis e comparáveis a resultados anteriores. Estudos adicionais são necessários.

Salvage Nipple-sparing Mastectomy for Patients with Breast Cancer Recurrence: A Case Series of Brazilian Patients / Mastectomia preservadora de mamilo para pacientes com recidiva de câncer de mama: Uma série de casos de pacientes brasileiras

Abstract Objective Few studies analyzed the safety of salvage nipple-sparing mastectomy (NSM) for local relapse treatment. We evaluated the outcomes of patients with indications for mastectomy who chose to undergo NSM for ipsilateral breast tumor recurrence (IBTR). Methods Between January 2001 and December 2018, we evaluated 24 women who underwent NSM for local relapse after conservative surgery. Results Thepatientswere followedupfor amean time of132months since thefirst surgery. After the NSM, 5 (20.8%) patients were diagnosed with local recurrence and only 1 (4.2%) patient died. The patients presented 4.8% (2) of partial and 2.4% (1) of total nipple necrosis. Conclusion In this long-term follow-up since the first surgery, we observed low rates of complication and good survival, although associated with high local recurrence in patients diagnosed with IBTR undergoing NSM as salvage surgery.We demonstrated that NSMmay be considered after IBTR for patients who did not want to undergo total mastectomy.

Resumo Objetivo Há poucos estudos sobre a segurança de se realizar adenomastectomia (nipple-sparing mastectomy, NSM, em inglês) para tratamento de recidiva local. O objetivo deste estudo foi avaliar os resultados de pacientes com indicação para mastectomia que optaram por se submeter a NSM para o tratamento de recorrência local. Métodos Foram analisadas 24 pacientes submetidas a NSM para tratamento de recidiva local após tratamento conservador entre janeiro de 2001 e dezembro de 2018. Resultados As pacientes foramacompanhadas por um períodomédio de 132meses a partir da primeira cirurgia. Após a NSM, 5 (20,8%) pacientes foram diagnosticadas com recorrência local, e apenas 1 paciente foi a óbito. As pacientes apresentaram 4,8% de necrose parcial e 2,4% de necrose total do mamilo. Conclusão Em um longo período de acompanhamento desde a primeira cirurgia, foram observadas baixas taxas de complicação pós-operatória e boa sobrevida, porém, associadas comuma alta taxa de recorrência local em pacientes submetidas a NSM para tratamento de recidiva local após cirurgia conservadora. Neste estudo, demonstrou-se que a NSM pode ser considerada uma opção cirúrgica para pacientes que não querem se submeter a mastectomia total.

Nipple-sparing Mastectomy with Immediate Implant-based Reconstruction for Patients with Pure Ductal Carcinoma in Situ / Mastectomia preservadora demamilo com reconstrução imediata baseada em implante para pacientes com carcinoma ductal puro in situ

Abstract Objective The presence of an extensive intraductal component is associated to an increasing risk of relapse in the nipple-areola complex. The aim of the present study was to evaluate the outcomes of patients diagnosed with ductal carcinoma in situ (DCIS) who underwent nipple-sparing mastectomy (NSM) with immediate breast reconstruction using silicone implants. Methods We retrospectively analyzed the postoperative complications and oncological safety of 67 breast cancer patients diagnosed with pure DCIS who underwent NSM with immediate breast reconstruction using silicone implants between 2004 and 2018. Results Among the 127 NSM procedures performed, 2 hematomas (1.5%) and 1 partial nipple necrosis (0.7%) were observed. After a mean follow-up of 60months, the local recurrence rate was of 8.9%, the disease-free survival rate was of 90%, and 1 of the patients died. Conclusion Despite the local recurrence rate, we showed that NSM with immediate breast reconstruction using silicone implants is a feasible surgical approach, with a low rate of complications and high survival rates for patients with a diagnosis of pure DCIS when breast-conserving surgery is not an option.

Resumo Objetivo A presença de componente intraductal extenso é associada ao risco aumentado de recorrência no complexo aréolo-mamilar. O objetivo deste estudo foi avaliar os resultados de pacientes diagnosticados com carcinoma ductal in situ (CDIS)submetidas a adenomastectomia (nipple-sparing mastectomy, NSM, em inglês) com reconstrução mamária imediata utilizando prótese de silicone. Métodos Restrospectivamente, foramanalisadas as complicações pós-operatórias e a segurança oncológica de 67 pacientes com câncer de mama diagnosticadas com CDIS puro, e submetidas a NSM com reconstrução mamária imediata utilizando prótese de silicone, entre 2004 e 2018. Resultados Entre os 127 procedimentos realizados, 2 hematomas (1,5%) e 1 necrose parcial de mamilo (0,7%) foram observados. Após um período médio de 60 meses de seguimento, a taxa de recorrência local foi de 8,9%, a sobrevida livre de doença, de 90%, e apenas 1 paciente foi a óbito. Conclusão Apesar da taxa de recorrência local, demostrou-se que NSM com reconstrução mamária imediata comprótese de silicone é umprocedimento viável, combaixa taxa de complicação e alta sobrevida para pacientes com diagnóstico de CDIS puro quando a cirurgia conservadora da mama não é uma opção.

Ginecomastia: Consideraciones médicas y quirúrgicas en cirugía general / Gynecomastia: Medical and surgical considerations in general surgery

La ginecomastia, definida como el crecimiento del tejido glandular mamario en los hombres, aparece desde la etapa neonatal hasta la senil, puede ser unilateral o bilateral, y es de causa multifactorial, incluyendo aquellos pacientes asociados al uso de medicamentos, donde predomina un desbalance en la relación testosterona­estrógeno. Relativamente, la idiopática es la más frecuente. La mayoría involucionan espontáneamente, las neonatales por perdida del influjo transplacentario en las primeras semanas, y las puberales entre 12 a 24 meses. Se presenta como un aumento del tamaño mamario, asintomático o con hipersensibilidad por inflamación durante el crecimiento del tejido fibroglandular mamario, con una repercusión psicológica enorme, sobre todo en la etapa de la adolescencia. El estudio y manejo es interdisciplinario y se ofrece de acuerdo con las condiciones y la etiología. Aquellos pacientes púberes en quienes no involuciona reciben tratamientos médicos, o tratamientos quirúrgicos cuando falla la terapéutica o hay presión social, e incluso radioterapia en casos donde desarrollan ginecomastia con hipersensibilidad al tratamiento hormonal del cáncer de próstata

Gynecomastia, defined as the growth of breast glandular tissue in men, appears from the neonatal to senile stage, can be unilateral or bilateral, and is of multifactorial cause, including those patients associated with the use of medications, where an imbalance in the testosterone ­ estrogen ratio. Relatively, idiopathic is the most common. Most regress spontaneously, neonatals due to loss of transplacental influx in the first weeks, and pubertal ones between 12 to 24 months. It presents as an increase in breast size, asymptomatic or with hypersensitivity due to inflammation during the growth of the mammary fibroglandular tissue, with an enormous psychological repercussion, especially in adolescence. The study and management is interdisciplinary and offered according to conditions and etiology. Those pubertal patients in whom it does not regress receive medical treatments, or surgical treatments when therapy fails or there is social pressure, and even radiotherapy in cases where they develop gynecomastia with hypersensitivity to hormonal treatment of prostate cancer

Masculinización torácica en pacientes trans / Thoracic masculinization in transsexual pacients

La mastectomía bilateral en pacientes transexuales de mujer a hombre es uno de los primeros procedimientos quirúrgicos y cuyos resultados son la creación de una pared torácica para el paciente trans. Su anatomía diferente y sus componentes serán reubicados y correspondidos con el de un paciente femenino. Se obtiene, entonces, un tórax estéticamente agradable en el cual la base está en la ubicación del complejo areola pezón (CAP), que será reposicionado y se cambiará de tamaño acorde al sexo reasignado. La técnica quirúrgica elegida ha sido conservando la irrigación del pedículo inferior y con conservación del CAP, el cual luego será reposicionado y modificado con respecto a su tamaño. Y en segundo tiempo su conformación final. Revisión y actualización tanto de la estética como la satisfacción del paciente trans.

Bilateral mastectomy in female-to-male transsexual patients is one of the first surgical procedures and whose results are the creation of a thoracic wall for the trans patient, its different anatomical and its components will be relocated and matched with that of a patient female. An aesthetically pleasing thorax is then obtained in which the base is in the location of the nipple areola complex (CAP), it will be repositioned and it will be resized according to the reassigned sex. The surgical technique chosen has been conserving the irrigation of the lower pedicle and conserving the CAP, which will then be repositioned and modified with respect to its size. And in the second time its final conformation. Review and update of both the aesthetics and satisfaction of the trans patient.

Development of Robotic Mastectomy Using a Single-Port Surgical Robot System / 한국유방암학회지

Minimal invasive surgical technique has been increasingly applied to breast surgery. Since the first robot-assisted nipple-sparing mastectomy was introduced, we have been performing nipple-sparing mastectomy using multi-port robotic surgical system. Last year, the new robotic surgical system with single port was introduced. We report the development of a robotic nipple-sparing mastectomy with immediate reconstruction through a single incision using the updated single-port surgical robot system for a patient with ductal carcinoma in situ (DCIS). Breast reconstruction was performed using implants. Postoperative pathological examination revealed DCIS in both breasts. There were no major immediate complications, except for a minor skin burn on the right breast. Overall, the initial operation using the updated platform was safely performed.

Nipple-sparing mastectomy through periareolar incision with immediate reconstruction

PURPOSE: Nipple-sparing mastectomy (NSM) has become increasingly popular due to improved cosmesis without compromising oncologic safety. Radial and inframammary incisions are usually used to achieve NSM, with periareolar incisions usually being avoided because of the risk to nipple-areola complex viability. In an attempt to maximize esthetic effects, we performed NSM through periareolar incision with immediate reconstruction. We report our initial experience.METHODS: This case series consisted of all consecutive patients (n = 34) who underwent NSM through a periareolar incision in our institution between August 2017 and December 2018. All patients underwent NSM through periareolar incision followed by immediate reconstruction with an implant or deep inferior epigastric perforator flap. Patient demographics, tumor and treatment characteristics, and short-term postoperative outcomes were reviewed.RESULTS: The mean patient age was 46.74 ± 6.69 years (range, 38–62 years), and the mean operation time was 96.68 ± 28.00 minutes. Indications included in situ cancer in 12 cases and invasive cancer in 22 cases. There was 1 major complication (postoperative hematoma) requiring operative reintervention. No other complications including fistula, implant exposure, or reconstruction failure was observed. At the time of writing, no case of local recurrence has been observed.CONCLUSION: Our initial report shows that NSM with immediate reconstruction may successfully be performed through periareolar incision. This method maximizes esthetic effects and may be an appropriate surgical option for NSM.

Reconstrução mamária após mastectomia contralateral profilática / Breast reconstruction after prophylactic contralateral mastectomy

Introdução: A indicação da mastectomia contralateral profilática (MCP) tem aumentado nos últimos anos nas pacientes fora do grupo de alto risco, apesar de seu benefício oncológico controverso em relação à sobrevida. A possibilidade da reconstrução mamária é um dos fatores mais importantes desse aumento. O objetivo é avaliar pacientes submetidas à MCP quanto às indicações e complicações após a reconstrução imediata. Método: Avaliação das pacientes submetidas à reconstrução mamária imediata após mastectomia terapêutica e MCP quanto às indicações e complicações. Resultados: Das 13 pacientes do estudo, apenas 4 apresentavam indicação de MCP por alto risco (forte história familiar). As outras indicações foram busca pela simetria, controle da ansiedade em relação à nova neoplasia e risco acumulado pela idade. Ocorreram apenas complicações menores, sem necessidade de reoperação em 4 das 13 pacientes (30,76%) e num total de 26 mamas reconstruídas foram registradas 8 complicações (30,76%). Conclusão: A realização da MCP tem aumentado, sendo que as indicações transcendem o ponto de vista oncológico, com impacto direto na atuação do cirurgião plástico quanto aos aspectos que envolvem a reconstrução, tanto no planejamento quanto suas complicações.

Introduction: Prophylactic contralateral mastectomy (PCM) has been increasingly indicated in recent years for patients outside of the high-risk group, although its cancer benefit in terms of survival remains controversial. The possibility of breast reconstruction is one of the most important factors for this indication. The objective of this study was to evaluate the indications and complications after immediate breast reconstruction in patients who underwent PCM. Method: Indications and complications were evaluated in patients who underwent immediate breast reconstruction after therapeutic mastectomy and PCM. Results: Of the 13 patients in the study, only 4 had a high-risk indication for PCM (strong family history). The other indications were desire for symmetry, control of anxiety related to neoplasm recurrence, and age-related risk. Only minor complications occurred, without a need for reoperation, in 4 of the 13 patients (30.76%). Eight complications (30.76%) in 26 reconstructed breasts were recorded. Conclusion: The number of PCM procedures has been increasing and the indications transcend the oncological point of view, directly influencing the performance of plastic surgeons with respect to the planning and complications of breast reconstruction.

Nova proposta para utilização de Becker 35 no segundo tempo de reconstrução mamária de grandes volumes / New proposal for the use of the Becker 35 expander in second large volume breast reconstruction

Introdução: A reconstrução imediata de mama realizada com o expansor de Becker é uma técnica de reconstrução versátil e consolidada na prática médica. Apresentamos uma proposta original com o uso do expansor de Becker associado a um segundo implante mamário. Métodos: Estudo retrospectivo realizado no período de janeiro de 2014 a outubro de 2016 no Hospital A.C. Camargo. A análise dos prontuários das pacientes reconstruídas com Becker 35 avaliou o índice e tipo de complicações e a associação de rádio e quimioterapia e comorbidades das pacientes com 5 casos de associação de implantes. Resultados: 193 reconstruções com Becker em 168 pacientes. Vinte cinco casos com reconstrução bilateral. Idade média de 47 anos e 33% apresentaram comorbidades. Cento e dezenove (62%) pacientes seguiram radioterapia e quimioterapia pós-operatórias. Complicações: seroma em 7 pacientes, hematoma no retalho da mastectomia em 2 pacientes, necrose parcial do retalho da mastectomia em 3 pacientes, necrose/infecção com exposição do expansor em 2 pacientes. O total de complicações foi de 9,5%. Um total de 133 (69%) pacientes foram submetidas a esta segunda etapa cirúrgica para complementação da reconstrução da mama, sendo o expansor de Becker substituído por um implante definitivo. As pacientes com uso de Becker 35 associado a outro implante não apresentaram complicações. Conclusões: A associação do implante-expansor de Becker 35 a um segundo implante mamário foi eficaz em atingir um volume maior nas reconstruções mamárias com baixo índice de complicações.

Introduction: Immediate breast reconstruction performed with the Becker expander is a versatile and accepted technique. We present an original proposal for the use of the Becker expander for a second breast implant. Methods: A retrospective study was performed between January 2014 and October 2016. Medical records were used to evaluate the indications and complications, the use of radio- and chemotherapy, and comorbidities in all patients, including 5 in whom combined implantation was performed. Results: The Becker expander was used for 193 reconstructions in 168 patients, including 25 cases with bilateral reconstructions. The average patient age was 47 years, and 33% had comorbidities. Postoperative radiotherapy and chemotherapy were performed in 119 patients (62%). Complications included seroma in 7 patients, hematoma in the mastectomy flap in 2 patients, partial necrosis of the mastectomy flap in 3 patients, and necrosis/infection with expander exposure in 2 patients. Complications occurred in 9.5% of the cases. A total of 133 (69%) patients underwent a second surgical stage to complement breast reconstruction, with the Becker expander being replaced by a definitive implant. Patients in whom the Becker 35 expander was used in a second breast implant developed no complications. Conclusions: the use of the Becker 35 expander for a second breast implant was effective in achieving greater volume in breast reconstruction with a low rate of complications.

Bilateral Autologous Breast Reconstruction in a Patient with Unilateral Breast Cancer: A Case Report

Various reconstructive and/or oncoplastic options are available for breast cancer patients. In properly selected patients, autologous tissue-based reconstruction usually results in aesthetic, natural breasts. The choice of a reconstructive option for a breast cancer patient is a multifactorial decision that should consider the patient's values and preferences, as well as oncologic variables. A case of a 47-year-old woman who underwent bilateral skin-sparing mastectomy (SSM) and bilateral abdominally-based reconstruction despite having unilateral breast cancer. Right SSM and left lumpectomy were indicated for ductal carcinoma in situ in the right breast and benign tumors with microcalcifications in the left breast. The patient had very small breasts and wished for larger breasts, using her own tissue, to be created in a single-stage operation. Right SSM and left subcutaneous mastectomy were followed by bilateral free transverse rectus abdominis flap reconstruction and nipple sharing.

Mastectomia redutora de pele com retalho dermogorduroso de pedículo inferior na reconstrução imediata de mamas com médias e grandes hipertrofias / Skin-reducing mastectomy using inferior pedicle dermal fat flaps in immediate reconstruction of medium and large hypertrophic breasts

Introdução: O câncer de mama é o tipo mais comum entre as mulheres (excetuando-se os de pele não melanoma) e nos últimos anos seu tratamento evoluiu muito com as mastectomias preservadoras de pele. As mamas com ptose grau II e III são de difícil abordagem e necessitam da redução estética do envelope cutâneo após o procedimento de adenomastectomia. Métodos: Foi realizado um estudo retrospectivo de janeiro de 2013 a janeiro de 2016 em que foram incluídas todas as pacientes submetidas à adenomastectomia e reconstruídas imediatamente através de redução do envelope cutâneo com a técnica de marcação de Pitanguy associada ao emprego de prótese ou expansor no plano submuscular superiormente e abaixo do retalho dermicogorduroso inferiormente. Resultados: Um total de 15 pacientes foram operadas pela técnica proposta, contabilizando um total de 25 mamas (10 casos foram bilaterais). Doze pacientes apresentavam câncer, duas realizaram cirurgia profilática e uma apresentava fibroadenoma gigante juvenil. Em dois casos foi utilizado expansor e em 23 mamas foi colocada a prótese definitiva em um único tempo cirúrgico. Em três mamas o complexo aerolopapilar (CAP) foi ressecado por motivos oncológicos; dos 22 preservados, em 15 foi realizado enxerto e em 7 ascensão através de retalho de pedículo superior. Houve 5 casos de complicação (20%), sendo 3 seromas (12%), 1 necrose na junção do 'T' (4%), e 1 necrose total do CAP (4%). Conclusão: A técnica descrita fornece um método eficaz e reproduzível de reconstrução mamária imediata com prótese em um tempo único em pacientes com mamas volumosas. Contudo, deve-se selecionar bem os pacientes, pois não se pode negligenciar os riscos de complicações.

Introduction: Breast cancer is the most common type of neoplasm among women (except for non-melanoma skin cancers), and in the past few years, its treatment greatly evolved with skin-sparing mastectomies. Breasts with grades II and III ptosis are difficult to approach and require an aesthetic reduction of the cutaneous envelope after adenomastectomy. Methods: A retrospective study was conducted from January 2013 to January 2016. This included all patients undergoing adenomastectomy and immediate reconstruction via reduction of the cutaneous envelope using Pitanguy's marking technique associated with the use of a prosthesis or expander above the submuscular plane and below the dermal fat flap. Results: A total of 15 patients were operated on based on the proposed technique, accounting for a total of 25 breasts (10 cases were bilateral). Twelve patients had cancer; two underwent prophylactic surgery; and one developed juvenile giant fibroadenoma. In two cases, an expander was used, and in 23 breasts, a definitive prosthesis was placed in a single surgical period. In three breasts, the nipple-areolar complex (NAC) was resected for oncological reasons; of the 22 preserved, 15 underwent grafting, and seven underwent elevation through the superior pedicle flap. There were five complications (20%): three seromas (12%), one necrosis at the "T" junction (4%), and one total NAC necrosis (4%). Conclusion: The technique described is an effective and reproducible method of immediate breast reconstruction using implants in a single period in patients with large breasts. However, the right patients should be selected because the risks of complications cannot be neglected.

The Lazy S Design: A Novel Skin Closure Design in Skin-Sparing Mastectomy for Implant-Based Breast Reconstruction

Preservation of the breast skin envelope during immediate implant-based breast reconstruction is important for producing symmetrical and natural-looking breasts. We propose the lazy S design for the closure of round-shaped wounds with the hope of improving the aesthetic outcomes and reducing the tension on the wound by preserving the skin. Additionally, the direction of tension is dispersed due to the shape of this design. Patients undergoing implant reconstruction after skin-sparing mastectomy may benefit from the lazy S design.

Gigantomastia juvenil. Hipertrofia virginal. Presentación de caso clínico / Juvenile macromastia. Virginal mammary hypertrophy. Case report

La gigantomastia juvenil es una afección médica benigna poco frecuente que causa el crecimiento excesivo y discapacitante de las mamas, provocando importantes trastornos físicos y psíquicos a pacientes púberes o adolescentes. Presentamos el caso en una paciente de 23 años, la cual se encontraba en la última etapa de su patología con una importante signosintomatología. Al no existir un tratamiento específico para ella, la mastoplastia reductiva es el procedimiento más efectivo con el que se cuenta. Se realizó una reducción de 9000 g de tejido mamario mediante la técnica de Torek, obteniendo mamas de volumen medio, simétricas, con cicatrices aceptables. La complejidad de esta patología hace que debamos manejarnos con un equipo multidisciplinario, tanto durante su estudio como en su tratamiento, y consideramos muy importante realizar un seguimiento estricto a largo plazo ya que es posible que, después del tratamiento quirúrgico, se presenten recurrencias.

Juvenile gigantomastia is a rare benign medical condition that causes excessive and disabling growth of the breasts and provokes considerable physical and psychological discomfort in patients in their puberty and adolescence. We introduce the case of a 23-year-old patient in the last stage of her condition with considerable signs and symptoms. There is no specific treatment for juvenile gigatomastia; hence breast reduction is the most effective procedure available. A reduction of 9,000 grams of breast tissue was performed using Torek's technique, resulting in medium volume, symmetrical breasts with acceptable scars. The complexity of this disorder requires a multidisciplinary team during the study and therapy stages. A strict long-term follow-up is recommended as relapses are possible after surgery.

Experience with Bilateral Risk-Reducing Mastectomy for an Unaffected BRCA Mutation Carrier / 한국유방암학회지

Women with BRCA1/2 mutations have a high risk of breast cancer and may opt for risk-reducing mastectomy (RRM). We report a 38-year-old Japanese woman who was diagnosed as a BRCA2 mutation carrier. She underwent prophylactic bilateral skin-sparing mastectomy (SSM) with excision of the nipple and preservation of the areola skin. It is unclear whether a bilateral RRM leads to better survival compared with intensive surveillance. The oncological risk associated with the presence of remnant breast glandular tissue after SSM or nipple-sparing mastectomy has been obscure. We report the first case of RRM for a Japanese BRCA mutation carrier and provide a literature review on risk management for BRCA mutation carriers with a focus on the concepts and procedures of RRM.

Treatment of Pseudoangiomatous Stromal Hyperplasia of the Breast: Implant-Based Reconstruction with a Vascularized Dermal Sling

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal lesion with incidental histologic findings. Surgical excision is recommended as the treatment of choice for PASH, although the recurrence rates after excision range from 15% to 22%. A 46-year-old-female presented with a six-month history of bilateral breast enlargement and painful sensation mimicking inflammatory carcinoma. Imaging studies demonstrated innumerable enhancing nodules in both breasts. Due to the growth of the lesions and progressive clinical symptoms, bilateral subcutaneous mastectomy was performed. Grossly, the specimens were round and well-circumscribed, and the histologic examination revealed PASH. After mastectomy, we created a pocket with the pectoralis major muscle and a lower skin flap, which was deepithelized. Anatomical mammary implants were inserted, and the nipple areolar complex was transferred to a new position as a free graft. The aesthetic result was satisfactory after twelve months of follow-up.

"Mini-Flow-Through" Deep Inferior Epigastric Perforator Flap for Breast Reconstruction with Preservation of Both Internal Mammary and Deep Inferior Epigastric Vessels

This procedure was developed for preservation of the rectus muscle components and deep inferior epigastric vessel after deep inferior epigastric perforator (DIEP) flap harvesting. A 53-year-old woman with granuloma caused by silicone injection underwent bilateral nipple-sparing mastectomies and immediate reconstruction with "mini-flow-through" DIEP flaps. The flaps were dissected based on the single largest perforator with a short segment of the lateral branch of the deep inferior epigastric vessel that was transected as a free flap for breast reconstruction. The short segments of the donor deep inferior epigastric vessel branch are primarily end-to-end anastomosed to each other. A short T-shaped pedicle mini-flow-through DIEP flap is interposed in the incised recipient's internal mammary vessels with two arterial and four concomitant venous anastomoses. Although it requires multiple vascular anastomoses and a short pedicle for the flap setting, the mini-flow-through DIEP flap provides a large pedicle caliber, enabling safer microsurgical anastomosis and well-vascularized tissue for creating a natural breast without consuming time or compromising the rectus muscle components and vascular flow of both the deep inferior epigastric and internal mammary vessels.

Contralateral Breast Symmetrisation in Immediate Prosthetic Breast Reconstruction after Unilateral Nipple-Sparing Mastectomy: The Tailored Reduction/Augmentation Mammaplasty

BACKGROUND: In the literature on nipple-sparing mastectomy (NSM) with one-stage immediate implant reconstruction, contralateral symmetrisation has drawn little attention, with many surgeons still performing standard cosmetic mammaplasty procedures. However, standard implant-based mammaplasty usually does not result in proper symmetry with the mastectomy side, especially regarding breast projection, overall shape, and volume distribution. METHODS: We retrospectively reviewed 19 consecutive patients undergoing unilateral NSM with immediate prosthetic reconstruction and contralateral simultaneous symmetrisation by using the tailored reduction/augmentation mammaplasty technique between June 2012 and August 2013. RESULTS: The average follow-up time was 13 months (range, 10-24 months). No major complications, such as infection, haematoma, and nipple-areola complex necrosis, were experienced. CONCLUSIONS: Our experience suggests that simultaneous contralateral symmetrisation with tailored reduction/augmentation mammaplasty after unilateral immediate implant reconstruction after NSM facilitates durable and pleasant symmetric outcomes.
