(2015) Yabanoglu, H.; Colakogiu, T.; Aytac, H. O.; Parlakgumus, A.; Bolat, F. A.; Pourbagher, A.; Yildirim, S.; 0000-0002-3583-9282; 0000-0003-0268-8999; 0000-0003-2031-7374; 0000-0002-5735-4315; 0000-0002-1161-3369; 26021788; AAJ-7913-2021; AAK-2011-2021; HJZ-1654-2023; AAF-4610-2019; AAJ-7865-2021
Background : To compare predicting factors for the diagnosis and clinical course of benign and malign/borderline phyllodes tumours (PT) of the breast, and to discuss treatment modalities. Methods : Clinical and demographic characteristics of the patients with histopathological diagnosis of phyllodes tumour were examined. Patients were divided into group 1 (benign PT) and group 2 (borderline/malignant PT). Groups were compared in terms of demographic and clinical characteristics. Results. Of the patients studied, 37(68.5%) had benign, 7 (12.9%) had borderline and 10 (18.5) had malignant histopathology.. A statistically significant relationship was detected between the incidence of malignancy and mass diameter (p = 0.001) and age (p = 0.030) when the two groups were compared. Wide surgical excision was performed on 46 (82.5%) patients, simple mastectomy on 7 (13%) patients and modified radical mastectomy on one (1.9%) patient. Ten (18.5%) patients were re-operated for surgical margin positivity. Local recurrence was determined only in one (1.9%) patient. Distant metastasis due to malignant PT developed in two (3.7%) patients. Conclusion : Among the patients who were considered to have PT, malignancy was likely to be present, especially if the patient's age was over 40 and the diameter of the mass was above 33.5 mm. Therefore, in patients with similar characteristics, surgical margins should be kept slightly wider or wider excisions should be preferred with or without simultaneous reconstructive surgery in appropriate cases.

Background : We retrospectively evaluated the results of surgical treatment for anterior abdominal wall desmoid tumours. Methods : Records for 13 patients operated on for desmoid tumours from 1997-2013 were searched for age, gender, abdominal/pelvic surgical history, pregnancy, Gardner's syndrome, pre-operative radiological examinations, tumour size, multifocality, surgical procedure, tumour presence at surgical margins, recurrence, morbidity, and mortality. Local recurrence-free survival probabilities were estimated by the Kaplan-Meier method and stratified by various clinicopathological variables. Results : There were 11 female (84,6%) and 2 male (15,4%) patients with a median age of 36 years. Seven (53,8%) patients had previous abdominal/pelvic surgery, five (38,5%) had a history of pregnancy, and one (7,6%) had Gardner's Syndrome. Two (15,3%) patients had multifocality on their pre-operative radiological examinations. Mean tumour diameter was 4,6 cm (SD 3,2 cm; range 2-12 cm). After the excision of the masses in five (38,5%) patients, synthetic materials were used to close the abdominal wall defects. Two (15,3%) patients with positive surgical margins after surgery were re-operated. Three (23%) patients required a second surgical intervention after the mass excisions were performed. Mean follow-up time was 56,7 months. Recurrence was observed in three patients during follow-up. Increased tumour size, history of previous abdominal/pelvic surgery, and the presence of multifocality had a negative effect on local recurrence-free survival. There was no mortality during follow-up. Conclusions : Desmoid tumours are characterized by high recurrence, even after proper surgical excisions. Preoperative differential diagnoses of these tumours should be done and a post-operative follow-up protocol should be followed.
Scar Endometriosis Is A Gynecological Complication that General Surgeons Have To Deal With
(2015) Aytac, H. O.; Aytac, P. C.; Parlakgumus, H. A.; 0000-0002-3583-9282; 26151995; AAC-9940-2020; AAJ-7913-2021
Background: Scar endometriosis is the presence of functional endometrium tissue in surgical incisions. It is a complication that develops after obstetrical or gynecological surgical procedures. As it presents with a mass adjacent to surgical incisions, general surgeons usually deal with it. The authors' aim was to review and discuss the differential diagnosis, treatment methods, recurrence rate, and follow up of scar endometriosis. Materials and Methods: Data of patients diagnosed with incisional scar endometriosis between 2005 and 2012 were recorded retrospectively. Their initial symptoms, previous surgery histories, onset of symptoms after surgery, duration of symptoms, diagnostic modalities, treatment methods, pathological evaluations, and rate of recurrences were documented and analyzed. Results: Seventeen patients were diagnosed to have scar endometriosis. Former surgical histories were one hysterectomy, one vaginal birth with episiotomy, and 15 cesarean sections. Sixteen of the scar endometrioses were demonstrated on pfannenstiel incision and one on episiotomy scar. Only one recurrence was seen during follow up. Conclusion: Scar endometriosis should be taken into account in the surgical practice of incisional site masses of the abdominal wall. They should be excised totally for a proper treatment. Patients must be warned about malignancy risk.
