The aim: To optimize the indications for partial laparoscopic adrenalectomy (PLA), to give a detailed outline of a PLA technique and to provide technical tips to ensure safe and highly-effectiveness, based on the knowledge of adrenal anatomy and blood supply. Materials and methods: Between January 2010 and September 2018, our department performed 47 adrenal glands surgeries. The operations included 29 total laparoscopic adrenalectomies (TLA), 4 open adrenalectomies (OA) and 14 partial laparoscopic adrenalectomies (PLA). Results: The histopathological examination of all operated patients detected 9 (19.1%) malignant tumors, including 5 metastatic tumors. Benign tumors includes 24 (63%) adenomas, 8 (21%) pheochromocytomas, 4 (10,5%) cysts and 2 (5,5%) ganglioneuromas. Post-PLA histopathological findings revealed 6 adenomas, 2 pheochromocytomas, 4 cysts and 2 ganglioneuromas. Conclusions: Keeping in mind anatomical features of adrenal gland blood supply in highly-selected patients, PLA can be performed in a number of patients. 2 mm of a minimal resection margin is enough to preserve a false tumor recurrence. Anatomically grounded PLA is becoming a new standard of benign adrenal gland tumors treatment, providing an opportunity to save more adrenal gland functional tissue and to prevent hipocorticism development in postoperative period.

ObjectiveThe objectives were to evaluate the risk of malignant adnexal tumors in women with nongynecologic malignancies and to identify variables associated with the risk of malignant adnexal tumors.MethodsThe eligibility criteria included the diagnosis of a nongynecologic malignancy and adnexal tumors, which were resected or subjected to biopsy at our institute between 1999 and 2010. The risk of malignant adnexal tumors was assessed by dividing the number of patients with metastatic tumors to the adnexa or primary adnexal cancers by the total number of patients. The association of clinicopathologic variables with the risk of malignant adnexal tumors was evaluated using the Fisher exact test and binary logistic regression analysis. In patients with metastatic tumors to the adnexa, the association of clinicopathologic variables with overall survival after adnexal surgery was examined using the log-rank test.ResultsIn 166 patients with adnexal tumors, 41 benign tumors, 113 metastatic tumors to the adnexa, and 12 primary adnexal cancers were diagnosed. Age older than 46 years, a tumor type associated with a high risk for malignant adnexal tumors, and bilateral tumors significantly increased the risk of malignant adnexal tumors. The overall survival of the patients with stomach cancer was significantly worse than the patients with colorectal or breast cancers.ConclusionOne hundred twenty-five of the 166 patients with nongynecologic malignancies who had adnexal tumors managed surgically were shown to have malignant tumors, and most of the tumors were metastatic from primary sites. The risk of malignant adnexal tumors was associated with age, nongynecologic malignancy, and bilaterality.

Abstract Background Only 14 cases of leiomyoma with ureteral origin have been reported previously. Such primary leiomyomas often present as hydronephrosis, making the diagnosis difficult. Radical nephroureterectomy is often performed because of the possible diagnosis of a malignant tumor. We report the 15th case of primary leiomyoma with a ureteral origin. Case presentation A 51-year-old Japanese man presented with a chief complaint of asymptomatic gross hematuria with a history of hypertension. Enhanced computed tomography showed a tumor at the upper part of the right ureter that appeared to be the cause of hydronephrosis and contracted kidney; no retroperitoneal lymphadenopathy and distal metastasis were observed. A well-defined 20-mm (diameter) defect was identified at the upper of the right ureter on retrograde pyelogram with no bladder cancer on cystoscopy. Urine cytology and right divided renal urine cytology findings were negative. Laparoscopic nephroureterectomy was performed, and the extracted tumor measured 20 × 13 mm. Histopathological examination revealed primary leiomyoma with no recurrence 16 months after the operation. Conclusions Preoperative examination with the latest available ureteroscopic technology can help preserve renal function in the case of benign tumors by enabling preoperative ureteroscopic biopsy or intraoperative rapid resection. Moreover, nephroureterectomy is recommended in the case of preoperative suspicion of ureteral malignant tumors.

Abstract Background: Laparoscopic adrenalectomy (LA) is the preferred approach to adrenal gland tumors. Objective: To evaluate the perioperative and functional outcomes of transperitoneal LA. Methods: We retrospectively reviewed data of all consecutive patients who underwent transperitoneal LA at our institution between April 2000 and December 2011. Results: Two hundred two patients with mean age of 46 years were included in the study. There were 109 left, 89 right, and 4 bilateral tumors. Preoperative diagnosis included 126 aldosterone-producing adenomas (APA), 33 patients with Cushing syndrome, 19 pheochromocytomas, 20 nonfunctional tumors, and 4 adrenal metastases. Mean tumor size was 3.3 cm (range 0.4-22 cm). Mean operative time was 109 min and estimated blood loss 90 mL for unilateral adrenalectomy; and 195 min and 300 mL for bilateral adrenalectomy. Four patients with pheochromocytoma required transfusion and 2 required conversion to an open approach. Seven intraoperative complications and 18 30-day postoperative complications occurred. These included 5 major complications (Clavien-Dindo grade 3-5). Ninety-seven percent of APA patients had normal serum potassium levels after surgery. Among the patients with functioning endocrine tumors, complete resolution rate from secondary hypertension was significantly higher in the pheochromocytoma group compared with those with APA or Cushing syndrome (82% vs. 48% vs. 68% respectively, p = 0.02). Mean follow up was 35.2 months. Conclusion: LA is the treatment of choice for most adrenal gland tumors with excellent outcomes and low complication rates. There was a high chance for complete resolution of secondary hypertension after surgery for pheochromocytoma.

Abstract Purpose: Laparoscopic adrenalectomy (LA) is controversial for large, potentially malignant tumors. We report a series of LA or hand-assisted LA for large (>5 cm) adrenal tumors. Patients and Methods: Among 210 LAs performed in 6 yr, 39 patients had potentially malignant tumors greater than 5 cm in diameter. Their perioperative and follow-up data were retrospectively analyzed. Results: All 39 patients had successful LAs without perioperative mortality, conversion to open surgery, or capsular disruption during dissection. The mean tumor size was 6.2 cm (range, 5–12 cm), operative time 207 min (115–315 min), and blood loss 75 ml (minimal–1400 ml). Complications included one intraoperative diaphragmatic perforation, three mild wound infections, and one pneumonia. Preoperatively there were 27 nonfunctioning tumors, seven pheochromocytomas, three cortisol-secreting tumors, and two virilizing tumors. Final pathology revealed eight malignant (four adrenocortical carcinomas and four metastatic carcinomas) and 31 benign tumors (14 cortical adenomas, eight pheochromocytomas, six myelolipomas, and three ganglioneuromas). Median follow-up was 39 months. Four patients (two adrenocortical carcinomas, one metastatic hepatoma, and one lymphoma) died 24, 10, 9, and 3 months after surgery, respectively. A hand-assisted device was used in 10 patients. Only the tumor size was larger and length of postoperative hospital stay longer for those in the hand-assisted group. Conclusions: LA is a reasonable option for selected large adrenal tumors when complete resection is technically feasible and there is no evidence of local invasion. Hand-assisted LA is a good alternative to open conversion if a difficult dissection is encountered intraoperatively.

Background:  Ovarian cysts are common forms of gynecological problems that can be range from physiological cysts to highly aggressive neoplastic lesions. The purpose of this study was to investigate prevalence and frequency of different histopathological patterns of ovarian lesions and their correlation with various parameters in Ahvaz, Iran.Materials and Methods: This is the retrospective study of patients with the ovarian masses at Ahvaz Imam Khomeini Hospital from 2010 - 2015. The relevant clinical details about the patient were retrieved from hospital data. Clinical characteristics of patients such as patient's age, presenting signs and symptoms, histopathological diagnosis, mass type, mass subtype, size of cysts and ovary which is involved were noted. Results: Two hundred sixty seven specimens of ovarian tumor obtained for histopathological examination. Of these, 163(61.0%) were tumor like, 96(36.0%) were benign tumor and 8(3.0%) were malignant. The most common tumor like conditions was Corpus luteum cyst (43.4% cases), among benign and malignant tumors, mature cystic teratoma (17.2% of total) and Epithelial tumors (n=4) were most common. There is a statistically significant positive relation between age and various ovarian masses. (P= 0.002). Histopathological diagnosis wasn't correlated with ovarian involvement.Conclusion: Benign tumors are more common than malignant tumors in all age groups. Germ cell tumors followed by surface epithelial cell tumors are the commonest tumor. Mature cystic teratoma was the most common tumor. Unilaterality is more frequently seen in ovarian tumors and various tumors are seen in various age groups.

Salivary gland tumours account for 2-6.5% of all the neoplasms of the Head and Neck. Histopathology is most important in diagnosis of salivary gland tumors. AIMS and OBJECTIVES : To study age,sex and site distribution of various salivary gland lesions, to study the histomorphologic (gross &microscopic) aspect of these lesions to correlate clinical diagnosis with that of histopathologic features. MATERIALS AND METHODS: The study is conducted in the RAINBOW CLINICAL LABORATORY AND RESEARCH CENTRE, SIDDIPET during the period of September2018 to September 2020. Formalin fixed ,paraffin embedded sections and stained with hematoxylin and eosin slides were studied. RESULTS: Total number of specimens were 54. Out of these 39 were neoplastic (benign 70%,malignant 30%) and 15 were non neoplastic. Among the benign tumors majority are pleomorphic adenoma.Among the malignant tumors, mucoepidermoid carcinoma is the most common. Among the non neoplastic lesions chronic sialadenitis is most common. CONCLUSION: Histopathological examination of salivary gland lesions stands out to be the most important method in establishing the final diagnosis. It helps in differentiating non neoplastic and neoplastic lesions.
