IntroductionPerivascular epithelioid cell tumors (PEComas) of the kidney are a group of tumor family covering classical angiomyolipoma (AML), microscopic AML (microhamartoma), intraglomerular lesions, cystic AML, epithelioid AML, oncocytoma-like AML and lymphangiomyomatosis of the renal sinus. The World Health Organization (WHO) defines PEComa as a "mesenchymal tumor that contains perivascular epithelioid cells presenting histological and immunohistochemical differences". While classical AML is benign, epithelioid AMLs are defined as potentially malign mesenchymal lesions for their capacity to develop local recurrence and metastasis (1,2,3). Surgical treatment may be required in AML for symptoms such as hemorrhage and pain, or for the risk of malignancy in tumors that cannot be differentiated from AML in the case of PEComa and certain variants of AML (3,4,5).This case report aimed to present a patient who undergone retroperitoneoscopic partial nephrectomy due to a renal mass and diagnosed with PEComa after pathological examination. Case PresentationWe planned magnetic resonance imaging (MRI) in a 25-year-old male patient, who was admitted to our clinic due to left-sided flank pain, with no pathological finding during the examination and laboratory tests, however, with a suspicious mass lesion located at the inferior pole of the left kidney detected during ultrasonographic examination. It was decided to perform surgical excision after detection of a 4 cm tumoral lesion in the inferior pole of the left kidney on MRI (Figure 1). We performed left retroperitoneoscopic partial nephrectomy in our clinic. The total operative time was 90 minutes with the warm ischemia time Böbreğin perivasküler epiteloid hücre tümörleri nadir görülen histolojik ve immünohistokimyasal olarak farklı perivasküler epiteloid hücrelerden oluşan mezenkimal tümörlerdir. Çoğunluğu benign tümörlerdir; fakat malign olanları agresif seyredebilir ve metastaza yol açabilir. Standart tedavi yöntemi ise cerrahi eksizyondur. Olgumuzda 25 yaşında sol böbrek alt polünde 4 cm kitle saptanan ve cerrahi olarak eksize ettiğimiz hastayı sunmayı amaçladık. Anahtar Kelimeler: Böbrek tümörü, perivasküler epiteloid hücre tümörü, parsiyel nefrektomi Perivascular epithelioid cell tumors are rare mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. They are mostly benign, however, malignant tumors with aggressive behavior and distant metastasis can also occur. The standard treatment is surgical excision. Here, we report a case of a 25-year-old male with a 4 cm-mass located in the inferior pole of the left kidney, treated by surgical excision.
Early repair with degloving method is effective method in postoperative erectile success in young patients. ABSTRACTWhat's known on the subject? and What does the study add? ÖZ ObjectiveIn this study, we aimed to present clinical characteristics and repair outcomes in patients who had sexual intercourse-induced penile trauma and underwent early surgical repair in our clinic. Materials and MethodsWe retrospectively evaluated records of patients who underwent early surgical repair due to penile trauma between 2004 and 2014 in our clinic. Preoperative, peroperative and postoperative data were analyzed. Patient characteristics, penile trauma characteristics, pre-trauma and postoperative International Index of Erectile Function-Erectile Function Domain Scores (IIEF-ED), and operation features were evaluated. ResultsTwenty-six male patients who were admitted to the emergency room with penile trauma and underwent early surgical repair were investigated. Four patients had only dorsal vein laceration and twenty-two had corpus cavernosum rupture. Postoperative erectile dysfunction was observed in three patients (the patients were older than 45 years of age, a patients had bilateral corpus cavernosum rupture and two patients had concomitant urethral trauma). Early repair was successful (86.4%) in the remaining 19 patients. The average erection hardness grade and IIEF-ED value were 4.75 and 28.6 before penile fracture; postoperative mean erection hardness grade and IIEF-ED value were found to be 4.2 and 24.9, respectively (p>0.05). ConclusionAs a result, in sexual intercourse-induced penile fracture, early repair with degloving approach is effective method in postoperative erectile success in young patients and patients with isolated unilateral fractures. KeywordsPenile fracture, early repair, International Index of Erectile FunctionErectile Function Domain Scores, urethral injury, erectile dysfunction AmaçBu çalışmada cinsel ilişki nedenli penil travması olan ve kliniğimizde erken cerrahi onarım uygulanan hastaların klinik özellikleri ve onarım sonuçlarını sunmayı amaçladık. Gereç ve Yöntem BulgularPenil travma nedenli acil servise başvuran ve degloving yöntemi ile erken cerrahi onarım uygulan 26 erkek hasta incelendi. Hastaların dördünde sadece dorsal ven laserasyonu, yirmi ikisinde kavernozum rüptürü mevcuttu. Üç hastada (üç hasta da 45 yaş üstüydü, birinde bilateral rüptür ve ikisinde eşlik eden üretral travma mevcuttu) postoperatif erektil disfonksiyon olduğu gözlendi. Geri kalan on dokuz hastada (%86,4) erken onarımın başarılı olduğu saptandı. Tüm hastaların fraktür öncesi ortalama ereksiyon sertlik derecesi 4,75 ve IIEF-ED değeri 28,6 iken, postoperatif ereksiyon sertlik derecesi 4,2 ve IIEF-ED değeri 24,9 saptandı (p>0,05). SonuçSonuç olarak cinsel ilişki sonucu gelişen penil fraktürlerde degloving yöntemi ile erken onarımın genç ve izole tek taraflı fraktürlerde postoperatif ereksiyon başarısında etkili yöntem olduğu söylenebilir. Anahtar KelimelerPenil fraktür, erken onarım, Uluslararası Erektil Fonksiyon İndeksi...
