Breast Metastases in Children and Adolescents With Rhabdomyosarcoma: A Large Single-Institution Experience and Literature Review.

INTRODUCTION: Breast metastasis is rare in childhood malignancies. Soft tissue sarcomas, especially rhabdomyosarcomas (RMS), and hematologic neoplasms, such as lymphomas, are the most common tumors that metastasize to the breast, albeit rare. MATERIALS AND METHODS: All cases with breast metastasis within a cohort of 200 RMS patients followed in our institution during 1990 to 2014 were assessed retrospectively and the literature was reviewed. RESULTS: There were 3 adolescent female patients with breast metastasis. All had alveolar histology. The primary tumors were in the parameningeal sites, extremities, and the perineum, respectively. Two patients had breast metastasis at diagnosis, and 1 during follow-up. In 1 breast lesion, there was a complete response to chemotherapy, and in another there was no response to chemotherapy, and the patient underwent radical mastectomy. In the third patient, there was partial response, and lesions progressed. All patients died with recurrent/progressive disease, 2 with no recurrence in the breast. In the English literature, there are 70 cases including our cases. All but 1 involve female patients, all adolescents, most have alveolar histology and poor prognosis. All had chemotherapy, whereas some had surgery and/or radiotherapy for local treatment. CONCLUSION: Breast metastasis should be considered in adolescent female patients with RMS. Optimal management is not clear. Besides chemotherapy, mastectomy and radiotherapy should be considered on a case basis.

The emerging role of national academies in surgical training: an inspiring environment for increasing the quality of health care in breast cancer management.

Medical education, both graduate and postgraduate, is given at medical schools and affiliated teaching hospitals. The training at these institutions is necessary and valuable. In each field of the medical profession, the relevant science is being developed and changed constantly. Training of medical staff and auxilliary professionals must be adaptable to changes in the field. Also, the development of standards for the diagnosis and treatment of diseases is important. Independent institutions, called academies, serve an extremely useful task in the continuing further training that needs to be adjusted according to individual needs. Academies are independent and free from bureaucracies. Standardized records are uniform and comparable at these institutions. Both patients and medical staff receive training from these institutions. In this way, a high standard is provided in medicine, error rates are decreased and patient satisfaction is increased. Breast cancer, the most common tumor in women, is a serious cause of morbidity and mortality. The European Institute of Oncology (EIO) in Milan, Italy and the European Academy of Senology in Duesseldorf, Germany play important roles in establishing the standards of breast care. They provide substantial training for physicians to achieve high quality in breast cancer management. SENATURK (Senoloji Akademisi, Turkish Academy of Senology) was established in 2010 in Istanbul, Turkey. Both national and international scientists and physicians including eminent senologists are currently faculty members of this young organization. SENATURK collaborates with other institutions in Europe. Its missions include developing training programs for each level of the profession, as well as developing data recording systems and electronic learning tools for breast cancer prevention, diagnosis, treatment, rehabilitation and palliation. Briefly, SENATURK plays a significant role as the opinion leader on every aspect of health care related to conditions and diseases of the breast.

Management of endocrine surgical disorders during COVID-19 pandemic: expert opinion for non-surgical options.

PURPOSE: The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic. METHODS: We used Delphi method with a nine-scale Likert scale on two rounds of voting involving 64 experienced eminent surgeons and endocrinologists who had the necessary experience to provide insight on endocrine disorder management. All voting was done by email using a standard questionnaire. RESULTS: Overall, 37 recommendations were voted on. In two rounds, all recommendations reached an agreement and were either endorsed or rejected. Endorsed statements include dietary change in primary hyperparathyroidism, Cinacalcet treatment in secondary hyperparathyroidism, alpha-blocker administration for pheochromocytoma, methimazole ± ß-blocker combination for Graves' disease, and follow-up for fine-needle aspiration results of thyroid nodules indicated as Bethesda 3-4 cytological results and papillary microcarcinoma. CONCLUSION: This survey summarizes expert opinion for the management of endocrine surgical conditions during unprecedented times when access to surgical treatment is severely disrupted. The statements are not applicable in circumstances in which surgical treatment is possible.

Clinical characteristics, late effects and outcomes in pineoblastomas in children: a single center experience.

BACKGROUND: Pineoblastomas (PB) are rare tumors of the central nervous system and are more common in children. There is no consensus about standard of care. The objective of this study is to analyze the outcome of children with PB. METHODS: Six patients with PB who were diagnosed between 1990-2012 were evaluated retrospectively. Demographics, age of diagnosis, first complaint, tumor region, diagnosis type, seeding metastasis to the spinal axis or cerebrospinal fluid (CSF), treatment and survival of these patients were recorded. RESULTS: Three patients had subtotal resection and all patients received chemotherapy and craniospinal irradiation (CSI) after diagnosis. Median follow-up after treatment was 5.5 (range:1-19) years. Two patients are alive with no evidence of disease for 7.5 and 10 years, one of whom was diagnosed with papillary thyroid carcinoma 9.5 years after treatment. One of the patients who died had lived for 19 years after diagnosis. CONCLUSIONS: Pineoblastomas are rare but very aggressive tumors; more effective treatment strategies are needed. Survivors should be followed up for late effects such as second malignancies and endocrine deficiencies.

The Positive Effects of a Calorie-Restricting High-Protein Diet Combined with Intragastric Botulinum Toxin Type A Application Among Morbidly Obese Patients: A Prospective, Observational Analysis of Eighty-Seven Grade 2 Obese Patients.

PURPOSE: Many studies evaluating the effect of intragastric botulinum toxin type A injection (IG-BTxA) for the treatment of obesity have been published. However, none of these studies combined this procedure with a calorie-restricting high-protein diet. Herein, we aimed to evaluate the effects of IG-BTxA application combined with a calorie-restricting high-protein diet. MATERIALS AND METHODS: This prospective cohort study is conducted with eighty-seven grade 2 obese patients treated between January 2019 and August 2019. Group 1: IG-BTxA + refused to consult the dietitian; group 2: IG-BTxA + get calorie-restricting high-protein diet; group 3: only get a calorie-restricting high-protein diet. Loss of weight, treatment adaptation (visual analog scale score), the status and changes of comorbid conditions, and changes in eating behaviors (Self-Regulation of Eating Behaviour Questionnaire score) were assessed. RESULTS: Loss of weight, treatment adaptation, and positive behavioral change in eating preferences were significantly higher in group 2 (p = 0.01; p = 0.001; p < 0.01, respectively). Additionally, the decrease in medication requirement for diabetes and hypertension was higher in group 2 (p < 0.05). CONCLUSION: IG-BTxA application before calorie-restricting high-protein diet facilitates adaptation to the new diet style and helps to lose weight faster in grade 2 obese patients. Also, more positive results were achieved in terms of controlling comorbid diseases.

An analysis of general surgery theses set up between years 1998-2018 in Turkey: Evidence levels and publication rates of 1996 theses.

OBJECTIVES: Setting up and advocating a thesis is mandatory at the end of the residency training program to become a specialist in general surgery according to the regulations on medical specialization in Turkey. Writing a thesis helps the resident to learn to ask structured questions, assembling the most accurate study design, managing the study process, collecting the results and building a conclusion with medical implications. In this descriptive study, we aimed to investigate the publication rates of the theses written in the field of general surgery and to assess the properties of the published theses. MATERIAL AND METHODS: We performed an online search on September 1, 2018, about the theses of general surgery residents on the website of National Thesis data center of Academic Educational Board in Turkey including theses of medical residents in university-affiliated hospitals and analyzed theses accomplished between 1998-2018. The publication status of the theses was assessed by the entry of author name, the title of the theses and keywords of the theses by using the search engines of PubMed, Google Scholar and Turkish Academic Network and Information Center Turkish Database (ULAKBIM). Data were presented in a descriptive form as absolute numbers and percentages. RESULTS: Between 1998-2018, 1996 theses were completed. 393 (20.5%) of these were published in a journal, and 288 (14.4%) were published in a journal indexed in SCI/SCIE. According to research methodologies, 79.2% of the experimental studies were published in SCI/SCIE indexed journals. CONCLUSION: Publication rates of the theses in the field of general surgery are low as they are in other specialties of medicine. This descriptive study might give an idea about the low scientific publication rates of general surgery theses. Further studies are needed to understand the underlying factors, which are responsible for this scant scientific performance.

Supernumerary ectopic parathyroid glands. Persistent hyperparathyroidism due to mediastinal parathyroid adenoma localized by preoperative single photon emission computed tomography and intraoperative gamma probe application.

Ectopic and/or supernumerary parathyroid glands are a major cause of persistent and recurrent Hyperparathyroidism (HPT). For this reason, it is widely accepted that preoperative localization should be performed to improve the surgical results in patients with persistent or recurrent HPT. Primary HPT (pHPT) was diagnosed incidentally in a 50-year old female patient during a preoperative examination for hernia. No pathologic parathyroid gland was detected in the preoperative Tc-99m Methoxybutylisonitrile (MIBI) scintigraphy and Ultrasonography (US). Cervical exploration was performed bilaterally. Four parathyroid glands were located adjacent to the thyroid gland. A fifth was detected in front of the cricoid cartilage. All five of them were of normal histology. Postoperatively, hypercalcemia persisted. Single Photon Emission Computed Tomography (SPECT) was performed before the second operation and radioguide surgery was carried out by median sternotomy. SPECT showed a parathyroid adenoma in the middle of the anterior mediastinum which was excised (size 1x0.5x0.5 cm) using a gamma probe. In conclusion, SPECT and intraoperative gamma probe application may help to detect the parathyroid adenomas, especially if they are small in size and buried in the adipose tissue. Such localization shortens the duration of the operation and reduces the possibility of complications.

Evaluation of the Reliability, Utility, and Quality of Information Used in Total Extraperitoneal Procedure for Inguinal Hernia Repair Videos Shared on WebSurg.

Purpose The Internet is widely used by patients and physicians for obtaining medical information. WebSurg is a valuable information resource that can improve the learning experience of medical professionals if used appropriately. This study aimed to evaluate the quality and accuracy of videos on the total extraperitoneal procedure (TEP) for inguinal hernia repair. Methods We included 32 videos returned by the WebSurg search engine in response to the keyword "TEP." Video popularity was evaluated using the video power index (VPI). The videos' educational quality was measured using the DISCERN score, Journal of American Medical Association (JAMA) benchmark criteria, and Global Quality Score (GQS). Technical quality was measured using the TEP Scoring System (TepSS) by three surgeons who performed TEP routinely. Results All videos were obtained from medical doctors; 12.5% of the videos were uploaded from Belgium; 3.1%, China; 6.3%, Colombia; 6.3%, England; 59.4%, France; 9.4%, Germany; and 3.1%, Korea. No significant differences were noted in terms of the VPI, DISCERN scores, JAMA benchmark criteria, GQSs, and TepSS scores (p > 0.05). The mean VPI, DISCERN score, JAMA benchmark criteria, GQS, and TepSS score were 9454.53 ± 15085.57, 32.75 ± 6.99, 2.31 ± 0.47, 1±0, and 9.25 ± 2.36, respectively. No significant associations were noted between the VPI and DISCERN score, JAMA benchmark criteria, and GQS (p > 0.05). Similarly, there was no significant association between the VPI and TepSS scores (r = 0.100; p = 0.587). Conclusions The online information on TEP is of suboptimal quality. Although limited information is available on preoperative and postoperative processes, the educational potential of WebSurg cannot be ignored.

Comparison of New Era's Education Platforms, YouTube® and WebSurg®, in Sleeve Gastrectomy.

INTRODUCTION: The Internet is a widely used resource for obtaining medical information. However, the quality of information on online platforms is still debated. Our goal in this quality-controlled WebSurg® and YouTube®-based study was to compare these two online video platforms in terms of the accuracy and quality of information about sleeve gastrectomy videos. METHODS: Most viewed (popular) videos returned by YouTube® search engine in response to the keyword "sleeve gastrectomy" were included in the study. The educational accuracy and quality of the videos were evaluated according to known scoring systems. A novel scoring system measured technical quality. The ten most viewed (popular) videos in WebSurg® in response to the keyword "sleeve gastrectomy" were compared with ten YouTube® videos with the highest educational/technical scores. RESULTS: Scoring systems measuring the educational accuracy and quality of WebSurg® videos were significantly higher than ten YouTube® videos which have the most top technical scores (p < 0.05), and no significant difference was found in the assessment of ten YouTube® videos that have the highest technical ratings compared with WebSurg® videos (p 0.481). CONCLUSIONS: WebSurg® videos, which were passed through a reviewing process and were mostly prepared by academicians, remained below the expected quality. The main limitation of WebSurg® and YouTube® is the lack of information on preoperative and postoperative processes.

Effects of Bathing Habits on Postoperative Wound Complications Following Sacrococcygeal Pilonidal Sinus Surgery: A Retrospective Analysis of 67 Adolescent Patients.

INTRODUCTION: Sacrococcygeal pilonidal sinus disease generally affects young people and impacts their quality of life. Few published studies assessing the characteristics of the disease in the adolescent population exist. OBJECTIVE: In this paper, the authors aim to evaluate the effects of bathing habits on wound complications in adolescent patients following Karydakis flap surgery for sacrococcygeal pilonidal sinus. MATERIALS AND METHODS: The medical records of 79 adolescent patients who underwent sacrococcygeal pilonidal sinus surgery between January 2014 and December 2017 at the Surgery Clinic of Malatya State Hospital (Malatya, Turkey) were evaluated retrospectively. Following exclusion, 67 patients were evaluated for demographics, body mass index (BMI), previous abscess formation, bathing frequency, number of sinus pits, and postoperative wound infection and dehiscence. The total follow-up time for the 67 patients was 90 days. RESULTS: The BMIs of patients with previous abscess formation were significantly higher (P = .029). In the cases with abscess, the number of pilonidal sinus pits was significantly higher (P = .039) There was a statistically significant difference between postoperative complication rates according to the number of baths per week. Wound infection rates were found to be higher in patients who bathed more than twice weekly during the 28 days after surgery (P = .005). No statistical significance was observed in complication rates from days 28 to 90 after the surgery between those who bathed twice weekly and more than twice weekly (P > .05). CONCLUSIONS: Postoperative wound complications in adolescent patients treated with Karydakis flap surgery for sacrococcygeal pilonidal sinus are more frequent in those who bathe more than twice weekly during the first 28 days postoperatively.

Comparison of the effects of two different marine-derived omega-3 fatty acid sources, krill oil, and fish oil, on the healing of primary colonic anastomoses after colectomy applied Wistar albino rat model.

BACKGROUND: Oils from marine organisms have a different fatty acid composition. Fish oil (FO) has a high content of eicosapentaenoic and docosahexaenoic acids esterified to triacylglycerols; while in krill oil (KO), fatty acids are primarily esterified to phospholipids. This study aimed to compare the efficacy of two different, marine-derived omega-3 fatty acid sources in the wound healing of colon anastomoses rat model. METHODS: For the study, we used 42 male Wistar albino rats. The rats were divided into six groups with seven rats in each group-CO3: left colonic anastomosis (control group), sacrificed on the third day; KO3: left colonic anastomosis + oral KO, sacrificed on the third day; FO3: left colonic anastomosis + oral FO, sacrificed on the third day; CO7: left colonic anastomosis (control group), sacrificed on the seventh day; KO7: left colonic anastomosis + oral KO, sacrificed on the seventh day; FO7: left colonic anastomosis + oral FO, sacrificed on the seventh day. Peritoneal adhesions, anastomotic bursting pressures, hydroxyproline levels, and histological examination of the anastomotic tissue were evaluated. RESULTS: On day 7, bursting pressure and hydroxyproline measurements of the KO group was significantly higher than the FO group (p=0.012; p=0.002, respectively). Also, on day 7, a statistically significant difference was observed between the groups according to inflammatory cell infiltration, fibroblast activity, neoangiogenesis, and collagen deposition in favor of the KO group (p=0.023; p=0.028; p=0.016; p=0.012, respectively). CONCLUSION: Both KO and FO supplementation in patients before colorectal surgery may reduce some risk of anastomotic leakage; and KO might be a better alternative and excellent omega-3 source.

Retrospective Analysis of the first 100 Kidney Transplants at the Istanbul Okan University, Health Application and Research Center.

OBJECTIVES: The renal transplant program of Istanbul Okan University Hospital started in August 2017. Five cadaveric and 95 living donor kidney transplants have been performed for over 16 months. In this study, we aimed to share our experiences regarding kidney transplantation. METHODS: In this study, a retrospective analysis of 100 patients who underwent kidney transplantation at the Istanbul Okan University over 16 months, the Health Application and Research Center was carried out. Patients' demographics, creatinine levels of donors and recipients, co-morbid conditions, postoperative complications, features of arterial anastomosis and arterial variations observed on computed tomography angiography of donor-patient were assessed. RESULTS: Mean age of donor patients was 44.05±13.76 (18-71) years. All living donors had computed tomography angiography for assessment of the vascular structure of both kidneys. Accessory right kidney artery was the most dominant vascular variation (16.5%). The primary cause of chronic renal disease was diabetes mellitus (36.4%) and hypertension (15.6%). Mean warm and cold ischemia time was 1.82±0.44 (1-3) and 40.25±6.12 (31-57) minutes, respectively. The most observed postoperative complication was stenosis of ureter anastomosis (4.1%). End-to-end arterial anastomosis between renal and internal iliac arteries was the most preferred anastomosis (57.2%). CONCLUSION: Increasing kidney transplantation, which is the most appropriate treatment in terms of cost-effectiveness, will be beneficial for patient health and economy of the country.

The Positive Effects of the Human Amniotic Membrane on the Healing of Staple Line After Sleeve Gastrectomy Applied Long-Evans Rat Model.

BACKGROUND: The staple line leakage is a dangerous complication of sleeve gastrectomy. Various strategies have been tried to reduce the leakage risk. The amniotic membrane (AmM) is the inner layer of the placental membranes and has anti-inflammatory, anti-fibrosis, and anti-scarring effects, and it also has lower immune characteristics which are another essential characteristic of AmM concerning its utility for grafting. In this study, we aimed to investigate the impact of AmM on the staple line healing process of sleeve gastrectomy model in rats. MATERIALS AND METHODS: We used twenty-eight Long-Evans rats in this study. Sleeve gastrectomy was performed with tristapler. Fourteen rats served as controls, AmM was applied staple line of the other fourteen. Fourteen animals were sacrificed (seven from the AmM applied group and the other seven from the control group) on the third postoperative day. And, the other fourteen animals were sacrificed (seven from the AmM applied group and seven from the control group) on the seventh postoperative day. The tissue around the staple line was evaluated microscopically and macroscopically, bursting pressures and hydroxyproline levels were also measured. RESULTS: The bursting pressure and hydroxyproline measurements of the AmM applied group was significantly higher on the seventh postoperative day (p = 0.015, p = 0.012) Fibroblast activity and neoangiogenesis of the AmM applied group was also significantly higher on the seventh postoperative day (p = 0.004, p = 0.002). CONCLUSION: This study showed that covering of staple line of sleeve gastrectomy model in rats significantly provided higher bursting pressures and increased hydroxyproline levels, fibroblast activity, and neoangiogenesis which may potentially lead a better staple line healing. We think further investigations are needed on this issue.

Primary Rhabdomyosarcoma of the Breast: Imaging Findings and Literature Review.

BACKGROUND: Primary breast rhabdomyosarcoma (RMS) can occur in children. There is a lack of knowledge regarding radiologic findings and added diffusion-weighted magnetic resonance imaging (MRI) features of RMS in the literature. CASE REPORT: A 12-year-old girl was diagnosed with primary alveolar RMS of the breast. Gray scale ultrasound revealed posterior acoustic enhancement behind a well-circumscribed, multilobulated hypoechoic mass. Doppler ultrasound revealed increased peripheral and central vascularity. Hypointense septations on T2-weighted image exhibiting more enhancement than the stroma on late gadolinium-enhanced images were striking within a hyperintense mass. A hyperintense hemorrhagic focus on T1-weighted image was present in the absence of any necrosis. Avid enhancement on early postcontrast images proceeding from the periphery to the center was depicted. CONCLUSION: A rapidly enlarging mass with an echogenic peripheral rim together with posterior acoustic enhancement on gray scale ultrasound, intense vascularity on Doppler ultrasound, axillary lymphadenopathy, and satellite nodules on MRI should raise suspicion. Enhancing central and peripheral septations are suggestive of RMS. Dynamic contrast-enhanced MRI in suspected cases can provide valuable data in the differential diagnosis.

Regional Clinical and Biochemical Differences among Patients with Primary Hyperparathyroidism.

BACKGROUND: Environmental habitat may play a role in clinical disparities of primary hyperparathyroidism (pHPT) patients. AIMS: To compare preoperative clinical symptoms and associated conditions and surgical findings in patients with pHPT, living in different geographical regions from the Black Sea, Mediterranean and Anatolia regions. STUDY DESIGN: Retrospective, clinical-based multi-centric study of 694 patients with pHPT. METHODS: Patients from 23 centers and 8 different geographical regions were included. Data related to baseline demographics, clinical, pathologic and treatment characteristics of 8 regions were collected and included age, gender, residential data, symptoms, history of fracture, existence of brown tumor, serum total Ca and p levels, serum parathormone (PTH) levels, serum 25-OH vitamin D levels, bone mineral density, size of the resected abnormal parathyroid gland(s), histology, as well as the presence of ectopia, presence of dual adenoma, and multiple endocrine neoplasia (MEN)- or familial-related disease. RESULTS: The median age was 54. Asymptomatic patient rate was 25%. The median PTH level was 232 pg/mL and serum total Ca was 11.4 mg/dL. Eighty-seven percent of patients had an adenoma and 90% of these had a single adenoma. Hyperplasia was detected in 79 patients and cancer in 9 patients. The median adenoma size was 16 mm. Significant parameters differing between regions were preoperative symptoms, serum Ca and p levels, and adenoma size. All patients from South-East Anatolia were symptomatic, while the lowest p values were reported from East Anatolia and the largest adenoma size, as well as highest Ca levels, were from Bulgaria. CONCLUSION: Habitat conditions vary between geographical regions. This affects the clinicopathological features of patients with pHPT.

The safety and accuracy of sentinel-node biopsy in early-stage invasive breast cancer--Turkish experience.

The purpose of this prospective study was to investigate the correlation of sentinel lymph node (SLN) and axillary lymph node (ALN) metastasis in early-stage invasive breast cancer in a single institution. One hundred and fifteen patients with early-stage invasive breast cancer first underwent SLND followed by an appropriate surgical procedure (modified radical mastectomy, lumpectomy + axillary dissection, simple mastectomy + mammoplasty). In this series, a radioactive agent (technetium) was used to investigate the sentinel lymph node/nodes. In 28 (24.3%) patients, metastases were found in both SLN and axillary dissections. There were no metastases in either of these procedures in 69 (60%) patients. SLN metastasis was found in 13 (11.3%) patients, but no axillary metastasis was found. No skip metastasis was detected. Five patients in whom the sentinel node was not found were also negative for axillary metastasis. As the studies progress in this direction, it might be possible to avoid axillary dissection in patients with early breast cancer in whom metastasis in SLN cannot be detected. We believe this will reduce morbidity from breast cancer surgeries.

Role of preoperative color doppler ultrasound scan in the evaluation of the risk of injury of major branches of the middle hepatic vein during laparoscopic cholecystectomy.

During laparoscopic cholecystectomy, the separation of the gallbladder from the liver bed may sometimes cause severe hemorrhages. One reason for severe hemorrhages may be injury to the major branches of the middle hepatic vein (MHV), which may be too close or adherent to the gallbladder. In our institutional experience of 798 laparoscopic cholecystectomies, no major hemorrhage from the gallbladder bed has been encountered. The aim of this prospective study was to investigate the relationship between the major branches of the MHV and the gallbladder bed in our patients. We measured the distance of the closest branches of the MHV from the gallbladder bed by color Doppler ultrasound scan. The mean and the median distances of the closest branch of the MHV to the gallbladder was found to be 17.4 +/- 6.2 mm and 17.7 mm, respectively (range, 6-29.1 mm). In conclusion, the distance of the closest branch of the MHV to the gallbladder bed in our patient population seems to allow for a safe laparoscopic cholecystectomy.

Bilateral nipple leiomyoma.

Cutaneous leiomyomas are benign smooth muscle neoplasms of the skin. They arise from vascular, arrector pili, genital, and areolar smooth muscles. The most common localizations of cutaneous leiomyomas are the extensor surfaces of the extremities and the trunk. To our knowledge, only few cases of one-sided nipple leiomyomas have been reported, but two-sided nipple leiomyomas have not been presented. For the first time, here, we report a bilateral nipple leiomyoma.
