RESUMO
Gynecomastia presents as abnormal hypertrophy of mammary tissue in males that is typically asymptomatic and usually does not require intervention. Gynecomastia responds well to medical and surgical treatment, when necessary, with low recurrence rates. The authors report an atypical case of recurrent idiopathic unilateral gynecomastia first presenting in an adolescent male. Physical examination, hormonal, and oncologic evaluations were normal. After subcutaneous mastectomy with liposuction and treatment with Tamoxifen at 19 years old, his unilateral gynecomastia recurred over the course of 3 years, requiring a second surgery. Furthermore, we review the literature for recurrent gynecomastia after surgical management to examine prevalence and risk factors.

OBJECTIVE: Gynecomastia is a benign proliferation of the glandular breast tissue in men and is generally caused by a decrease in androgen and an increase in estrogen. Diabetes has been reported to be a risk factor for lowering androgen levels. Moreover, lowered androgen levels are more common in older men. In the present study, we aimed to evaluate the signals for gynecomastia in older men on antidiabetic medications. MATERIALS AND METHODS: A disproportionality analysis was performed to detect the signals for antidiabetic drug-associated gynecomastia in the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) and the Japanese Adverse Drug Event Report database (JADER), using the reporting odds ratio (ROR) and information component (IC). RESULTS: Among 8 classes of medications for diabetes, a signal was detected only for dipeptidyl peptidase-4 (DPP-4) inhibitors (ROR: 1.90, 95% confidence interval (CI): 1.27 - 2.83; IC: 0.84, 95% CI: 0.26 - 1.42) in the FAERS. Regarding individual drugs, ROR and IC signals were detected for sitagliptin (ROR: 2.37, 95% CI: 1.48 - 3.79; IC: 1.12, 95% CI: 0.44 - 1.79) and vildagliptin (ROR: 3.34, 95% CI: 1.39 - 8.08; IC: 1.26, 95% CI: 0.07 - 2.44) in the FAERS and only for sitagliptin (ROR: 4.84, 95% CI: 1.92 - 12.2; IC: 1.48, 95% CI: 0.24 - 2.73) in the JADER. CONCLUSION: This study showed an association between DPP-4 inhibitor use and gynecomastia in older men with diabetes. Further pharmacoepidemiological studies are warranted to verify this finding.

Gynecomastia is a more common finding in primary care clinics than is recognized. Because this finding can be easily overlooked, appropriate investigation and management often are missed. The workup of gynecomastia is highly individualized, based on the patient's presentation and related factors. It should be guided by thorough history taking and physical examination. Unless the patient has associated symptoms, or there is suspicion for an underlying clinical disorder causing the gynecomastia, the patient need not be investigated further. A breast ultrasound is not routinely recommended. Gynecomastia is a benign finding that will spontaneously regress in most patients; however, patients who are concerned with their physical appearance can be treated either medically or surgically. Patients who have had gynecomastia for more than 1 year tend to have fibrosis, which may be more difficult to treat. Management of gynecomastia is highly patient centered, following a detailed discussion about treatment goals and should be started early. Gynecomastia is not considered a premalignant condition; routine screening is not cost-effective, and imaging studies should be pursued only if physical examination findings suggest malignancy.

Gynecomastia is the most frequently breast lesion in males. 148 patients (mean age 24,7 years) operated in our department were reviewed with a mean follow-up of five years. Gynecomastia occurred most frequently during puberty (77,7 %), was bilateral (86,5%) and idiopathic (89,9%). The size of the enlargement was evaluated according to Simon's-classification based on breast-volume and skin-redundancy. 17 (11,5%) stage 1, 77 (52%) stage 2A, 32 (21,6%) stage 2B, 22 (14,9%) stage 3. Clinical examination and mammography determined the consistency of gynecomastia: adipose or firm. 4 different surgical managements were used: 17 (11,5%) subcutaneous mastectomies, 4 (2,7%) liposuctions, 110 (74,3%) liposuctions associated with subcutaneous mastectomy, 17 (11,5%) total mastectomy. All techniques gave good morphologic results. Nonetheless, the authors recommend the combination «liposuction and subcutaneous mastectomy¼, as this technique presents many advantages: small intraoperative blood loss, good skin redraping, short hospital stay, complete histologic examination of the material removed.

Although pubertal gynecomastia is a common clinical presentation of adolescent males, prepubertal gynecomastia is uncommon and mostly idiopathic. However, pathological causes of prepubescent gynecomastia are encountered in clinical practice. This manuscript carries an important message to general pediatricians, to care about exclusion of pathological causes for every patient of prepubertal gynecomastia. We present four different patients with pathological gynecomastia. One of them revealed to be secondary to Sertoli cell tumor, while the second patient describes trauma as a rare cause of prepubertal true gynecomastia. To the best of our knowledge, this is the first time to report occupational trauma as a cause of true gynecomastia as confirmed by pathological specimen, in a prepubertal boy. The third patient presented with retro-areolar mass and bloody nipple discharge secondary to mammary duct ectasia and had favorable self-limited course. Hyperprolactinemia secondary to neglected congenital hypothyroidism was the cause beyond gynecomastia in the fourth patient and this cause has been reported only once in the literature.Conclusion: Despite being rare, pathological causes of prepubertal gynecomastia are encountered in clinical practice, and full investigations including breast and testicular ultrasound are needed to exclude any pathology before diagnosing idiopathic gynecomastia. Repeated friction of the breast can lead to true gynecomastia not only to pseudogynecomastia as previously known. What is Known: ⢠It has been reported that trauma can cause pseudogynecomastia due to hematoma or fat necrosis. ⢠Prepubertal gynecomastia is mostly idiopathic. What is New: ⢠Long-term breast trauma can cause true gynecomastia (adenosis). ⢠Although being mostly idiopathic, pathological causes of prepubertal gynecomastia must be ruled out.

The aim was to define the true incidence of gynaecomastia in adolescent boys with Klinefelter syndrome (KS) and to observe testosterone treatment effects on its duration by examination of the prospectively collected data from a specialist referral clinic for boys with KS, with comparison being made with KS boys identified by a historical newborn chromosome screening programme, together with chromosomally normal controls. Fifty-nine boys over age 13 years were referred to a specialist KS clinic; 21 developed gynaecomastia. The comparator was 14 KS boys identified at birth and 94 chromosomally normal control boys. Testosterone was routinely started at the onset of puberty if gynaecomastia, a manifestation of clinical hypogonadism, was present. Oral or transdermal testosterone was administered in the morning, in a reverse physiological rhythm, and doses were increased according to standard pubertal regimens. The incidence of gynaecomastia was not increased in both the KS cohorts compared with controls. The incidence and age of onset of gynaecomastia was 35.6%, at 12.3 (1.8) years in the KS clinic group; 36.0%, at 13.7 (0.6) years in the newborn survey group; and 34.0%, at 13.6 (0.8) years in the controls. Full resolution of the gynaecomastia occurred in the 12/14 KS clinic boys on testosterone treatment who had completed puberty and as long as adherence was maintained.Conclusion: The incidence of gynaecomastia in KS boys (overall 35.6%) is not increased over typically developing boys. Commencing testosterone when gynaecomastia develops with physiological dose escalation and full adherence can result in the resolution of the gynaecomastia. What is Known: ⢠Gynaecomastia is a common feature in Klinefelter syndrome men. ⢠Hypogonadism occurs from mid-puberty onwards with the absence of the usual rise in testosterone levels. What is New: ⢠The incidence of pubertal gynaecomastia in Klinefelter syndrome is not different from typically developing boys. ⢠Early and prompt starting of testosterone gel treatment and increasing the dose physiologically may help to resolve the gynaecomastia without the need for surgery.

ABSTRACT: This article reviews the most up-to-date evidence-based recommendations pertaining to breast and upper chest conditions, specifically for the sports medicine physician. Because of the unique circumstances of the team physician, they can see a wide breadth of pathology. Athletes may not have a primary care physician and may prefer to present to their team physician for breast and upper chest conditions. It is often more comfortable and convenient for athletes to seek treatment in the team setting. Therefore, it is important that the medical professional be aware of not only common pathology but also of that which is rarer. Any delay in evaluation can result in unnecessary morbidity and lead to complications or extended time lost from sport. Consequently, it also is important to facilitate an atmosphere encouraging early presentation and workup.

BACKGROUND: To investigate the prevalence and risk factors of premature thelarche (PT) in girls and gynecomastia (GM) in boys in Southern China. METHODS: We conducted a cross-sectional study of preschool children across 9 cities in Zhejiang province. A total of 6273 children in the age-group of 2-7 years were recruited from January 2014 to March 2015. Relevant information was collected from mothers through face-to-face interviews. Logistic regression models were used to examine the correlates of PT and GM. Odds ratios (ORs) with 95% confidence intervals (CIs) are reported. RESULTS: The prevalence of PT among girls was 4.8% and that of GM among boys was 0.8%. One hundred girls were diagnosed with PT before the age of 2 years; 69 (69.0%) of these girls experienced spontaneous resolution of PT. Twenty-four boys were diagnosed with GM before the age of 2 years; 10 (41.7%) of these experienced spontaneous resolution of GM. Children borne of mothers with early onset of menarche and those belonging to high-income families were at a higher risk of premature breast development. Greater consumption of eggs was associated with premature breast development in early childhood. CONCLUSIONS: Socioeconomic status of family, early onset of menarche in mother, and consumption of eggs were strongly associated with premature breast development in early childhood.

Disorders of sex development (DSD) are defined as discrepancy between chromosomal, gonadal and anatomic sex. The basic principles for the management of DSD include a multidisciplinary approach for gender assignment. Clinical assessment includes a detailed history and examination of external genitalia. Most of the disorders with symmetrical gonades indicate hormonal cause while asymmetrical gonades are found in chromosomal DSDs. Karyotyping will indicate a 46XX DSD, 46 XY DSD or mosicism. Internal anatomy is defined by ultrasonography, genitoscopy and laparoscopy. Human chorionic gonadotrophins (hCG) stimulation test is carried out in under-virilised males to see the function of Leydig cells in testes. The Most common cause of 46XX DSD is congenital adrenal hyperplasia (CAH). The decision of gender assignment surgery is to be taken in a multidisciplinary environment and with informed consent of the parents. Most of 46 XX CAH patients, even if markedly virilised, and 46 XY complete androgen insensitivity syndrome are raised as females. Similarly, most of 5-α reductase deficiency and 17-ß hydroxysteroid dehydrogenase deficiency patients are assigned to the male gender. The decision in cases of mixed gondal dysgenesis and ovotesticular DSD is based on the development of external and internal genitalia. Patients with androgen biosynthetic defects, partial androgen insensitivity syndrome are usually assigned to the male gender.

Gynaecomastia may be due to medication, chronic liver or kidney disease, hypogonadism (primary or secondary to pituitary disease) or hyperthyroidism. Having excluded these aetiologies, it is imperative to be vigilant for underlying malignancy causing gynaecomastia. These include human chorionic gonadotrophin-secreting testicular and extratesticular tumours and oestrogen-secreting testicular tumours and feminising adrenal tumours.

PURPOSE OF REVIEW: Our aim is to review the steps of diagnosis and management of gynecomastia with a special focus on treatment of gynecomastia associated with androgen deprivation therapy for prostate cancer. RECENT FINDINGS: Recent studies investigating tamoxifen and radiation therapy for both therapy and prophylaxis of bicalutamide-induced gynecomastia are reviewed. Gynecomastia is a common clinical problem, affecting between one and two thirds of middle-aged men. Diagnosis is typically made by history and physical exam. Common causes include chronic medical conditions and medications; however, unexplained gynecomastia should prompt laboratory work-up, followed by appropriate imaging studies to evaluate for hormone producing cancers. For patients taking bicalutamide for treatment of prostate cancer, tamoxifen or radiation therapy for gynecomastia are excellent options.

BACKGROUND: Pseudogynecomastia is the increased aggregation of fatty tissue in the area of the male breast with resultant female appearance. Two forms can appear: pseudogynecomastia after massive weight loss (pseudogynecomastia obese [PO]) and pseudogynecomastia, which is caused only by adipose tissue (pseudogynecomastia fat). For PO, only the Gusenoff classification with corresponding operative treatment options exists. However, this classification is limited by the fact that it underestimates the extensive variability of residual fat tissue and skin excess, both crucial factors for operative planning. For this reason, we propose a modification of the treatment algorithm for the Gusenoff classification based on our results to achieve more masculine results. MATERIALS AND METHODS: A total of 43 male patients with PO were included in this retrospective study (grade 1a, n = 1; grade 1b, n = 1; grade 2, n = 17; grade 3, n = 24). Forty-two mastectomies with a free nipple-areola complex (NAC) transposition (grades 2 and 3) and 1 with a subcutaneous mastectomy (grade 1a) with periareolar lifting were performed. A retrospective chart review was performed to obtain data regarding age, body mass index, body mass index loss, weight loss, reason for weight loss, comorbidities, nicotine, and additional procedures, postoperative sensitive on the NAC transplants and complications. RESULTS: None of the free-nipple grafts were lost. Forty (95%) of 42 patients with mastectomy had a resensitivity on the NAC. CONCLUSIONS: For pseudogynecomastia, the treatment algorithm of the Gusenoff classification should be modified and adapted according to our recommendations to achieve more optimal masculine results.

BACKGROUND: Gynaecomastia is a benign enlargement of the male breast, of which the psychological burden on the patient can be considerable, with the increased risk of disorders such as depression, anxiety, and social phobia. Minimal scarring can be achieved by liposuction alone, though it is known to have a limited effect on the dense glandular and fibroconnective tissues. We know of few studies published on "liposuction alone", so we designed this study to evaluate the outcome of combining liposuction with glandular liposculpturing through two axillary incisions as a single treatment for the management of grades I and II gynaecomastia. METHODS: We made a retrospective analysis of 18 patients with grade I or II gynaecomastia who were operated on by combined liposuction and glandular liposculpturing using a fat disruptor cannula, without glandular excision, during the period 2014-2016. Patient satisfaction was assessed using the Breast Evaluation Questionnaire (BEQ), which is a 5-point Likert scale (1 = very dissatisfied; 2 = dissatisfied; 3 = neither; 4 = satisfied; 5 = very satisfied). The post-operative aesthetic appearance of the chest was evaluated by five independent observers on a scale from 1 to 5 (5 = considerable improvement). RESULTS: The patient mean (SD) overall satisfaction score was 4.7 (0.7), in which 92% of the responders were "satisfied" to "very satisfied". The mean (SD) BEQ for all questions answered increased from 2.1 (0.2) "dissatisfied" preoperatively to 4.1 (0.2) "satisfied" post-operatively. The observers' mean (SD) rate for the improvement in the shape of the front chest wall was 4.1 (0.7). No haematomas were recorded, one patient developed a wound infection, and two patients complained of remnants of tissue. The median (IQR) body mass index was 27.4 (26.7-29.4), 11 patients had gynaecomastia grade I, and 7 patients grade II. The median (IQR) volume of aspirated fat was 700 ml (650-800), operating time was 67 (65-75) minutes, 14 patients had general anaesthesia, and hospital charges were US$ 538 (481-594). CONCLUSIONS: Combined liposuction and liposculpturing using the fat disruptor cannula resulted in satisfied patients and acceptable outcomes according to the observers' ratings. It could be a useful alternative with an outcome that corresponds to that of more expensive methods.

INTRODUCTION: The objectives of this study are: (1) comparison of long-term outcomes after correction of severe gynecomastia using different techniques; (2) apply the Italian version of the BODY-Q; (3) present the role of intercostal perforator flap (ICAP) after massive weight loss for correction of severe gynecomastia. MATERIALS AND METHODS: Between January 2008 and March 2016, we performed surgical correction of bilateral severe gynecomastia in 80 men (160 breasts) following massive weight loss. Patients answered the Italian version of BODY-Q postoperative module. All patients had experienced substantial weight loss (> 30 kg), presented with bilateral severe tissue ptosis of the breast, follow-up of almost 2 years and had a good understanding of the Italian language, and signed consents were included in the study. The sample was studied about age, BMI, comorbidity, bariatric surgical procedure, follow-up, type of post-bariatric surgical procedure, complications and secondary procedures. RESULTS: We performed 487 severe gynecomastia corrections from 2008 to 2016; 80 patients adhered to the inclusion criteria and formed our study group. This cross-sectional study compared three cohorts: 52 access using a circumareolar scar, 18 with an inframammary fold scar, 10 with an inframammary fold scar using intercostal perforator flaps. There were 16 secondary procedures in group one, 2 in group two and 1 in group three. We compared the secondary procedures of group 1 with the other groups, and we obtained a significant difference with a P = 0.04. The mean patient age was 36.5 years, and the average body mass index was 27.5 kg/m2 at the time of surgical correction of gynecomastia. From the BODY-Q analysis, the group of patients undergoing adenomammectomy with inframammary fold scar using intercostal perforator flaps has achieved significantly better results regarding the satisfaction with chest, psychosocial function, satisfaction with outcome and better body image. CONCLUSIONS: This is the first study that used the BODY-Q to analyze the correction of severe gynecomastia following massive weight loss with long-term results. The use of this patient-reported outcome measure underlined that the intercostal artery perforator flap, used in the correction of severe gynecomastia following massive weight loss, is a safe and effective technique with good outcomes and high patient satisfaction.

INTRODUCTION: Aesthetic breast area improvements for gynecomastia and gender dysphoria patients who seek a more masculine appearance have increased recently. We present our clinical experience in breast masculinization and a classification for these patients. METHODS AND MATERIALS: From July 2003 to May 2014, 68 patients seeking a more masculine thorax underwent surgery. They were divided into five groups depending on three factors: excess fatty tissue, breast tissue, and skin. A specific surgical treatment was assigned according to each group. The surgical treatments included thoracic liposuction, subcutaneous mastectomy, periareolar skin resection in one or two stages, and mastectomy with a nipple areola complex graft. The evaluation was performed 6 months after surgery to determine the degree of satisfaction and presence of complications. RESULTS: Surgery was performed on a total of 68 patients, 45 male and 22 female, with ages ranging from 18 to 49 years, and an average age of 33 years. Liposuction alone was performed on five patients; subcutaneous mastectomy was performed on eight patients; subcutaneous mastectomy combined with liposuction was performed on 27 patients; periareolar skin resection was performed on 11 patients; and mastectomy with NAC free grafts was performed on 16 patients. The surgical procedure satisfied 94% of the patients, with very few complications. CONCLUSIONS: All patients who wish to obtain a masculine breast shape should be treated with only one objective regardless patient's gender: to obtain a masculine thorax. We recommend a simple mammary gland classification for determining the best surgical treatment for these patients LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.
