Laparoscopic resection of giant adrenal myelolipoma: A case report with review of literature.

Giant adrenal myelolipoma (AML) may cause severe symptoms. In contrast to the previous reports, laparoscopy may play a pivotal role in the management of giant AML. This report aims to discuss a case of giant AML managed successfully by laparoscopy. A 63-year-old male was found to have a giant (12 × 10 × 8 cm) left AML during a workup for left lower chest pain on imaging. laparoscopic excision of a left adrenal gland with the lesion was performed under general anesthesia. The patient was discharged from the hospital after 3 days uneventfully. AML is a benign tumor that is characterized by the presence of adipose tissue and hematopoietic elements. Myelolipomas are typically asymptomatic. AML diagnosis is based on imaging and blood workup. Small asymptomatic AML is usually managed conservatively, while symptomatic AML is managed with surgery. Even though an open approach is the standard option, laparoscopy, as a minimally invasive technique, in some centers may replace laparotomy. Laparoscopy can be a successful method for managing AML, even when they are large in size.

Thoracic outlet syndrome caused by superior mediastinal mass: A case report.

INTRODUCTION: Thoracic outlet syndrome (TOS) caused by superior mediastinal soft tissue mass has never been reported in the literature, the aim of this study is to discuss a case of TOS caused by a superior mediastinal mass in which the histopathological examinations of the mass showed vascular malformation. CASE REPORT: A 45-year-old female presented with left upper limb pain and numbness for three months, associated with swelling and attacks of shortness of breath. Imaging studies showed soft tissue mass involving the superior mediastinum. The condition of the patient deteriorated and the signs and symptoms of TOS became clearer, all provocative tests and nerve conduction studies were positive. The patient underwent thoracic outlet decompression. The patient did not respond and the symptoms deteriorated further. After a multidisciplinary board discussion, the patient was prepared for median sternotomy under general anesthesia. A total resection of the mass was done. The patient was totally relieved a few hours after the operation. DISCUSSION: The etiology of TOS can be multifaceted. Several factors contribute to its onset, and these can be categorized as congenital or acquired. Congenital causes include anatomical anomalies such as a cervical rib, or an elongated transverse process of the cervical vertebrae. These anatomical deviations can reduce the size of the thoracic outlet and make it prone to compression. CONCLUSION: Although it is rare, TOS could be due to superior mediastinal mass and the treatment of choice is total resection either through median sternotomy or thoracoscopic procedure.

Diagnosis of a pulmonary hydatid cyst by fine needle aspiration: a case report with literature review.

Introduction and importance: Hydatid cysts are seldom identified in cytologic smears and are often incidental. This report highlights a case where fine needle aspiration cytology was unintentionally utilized to diagnose a pulmonary hydatid cyst clinically mistaken for an abscess. Case presentation: A 29-year-old female presented with intermittent respiratory symptoms, including a mild cough and sputum, that she has been complaining of since 2020. A blood investigation revealed an elevated erythrocyte sedimentation rate (25 mm/h), C-reactive protein (>5 mg/dl), and white blood cells (>11×109/l). A high-resolution computed tomography scan of the chest revealed an irregular pulmonary opacity in the right lower lobe with central fluid attenuation, suspecting an abscess or, less likely, a pulmonary neoplasm. The patient underwent fine needle aspiration cytology, which was diagnosed as a hydatid cyst. A thoracotomy was performed, and the cyst was totally excised. Histopathological results of the specimen confirmed the previous diagnosis. Clinical discussion: Various diagnostic modalities have been discussed for diagnosing hydatid cysts, including radiology, serology tests, and fine needle aspiration. These modalities have been evaluated in terms of their respective advantages and drawbacks. Conclusion: Hydatid cysts can be challenging to diagnose based on imaging findings and may be misidentified as abscesses or masses. Despite the risk of anaphylaxis, fine needle aspiration cytology can be a reliable diagnostic method if performed meticulously by experienced radiologists.

Myeloid osseous metaplasia of the lung: A case report.

Pulmonary osseous metaplasia is a disease in which mature bone is found within the parenchyma of the lung. The current study presents a case of pulmonary osseous metaplasia in a 64-year-old female. The patient was previously diagnosed with transitional cell carcinoma (TCC) of the lower ureter. During a routine check-up, an enhancing basal lung nodule was found on chest computed tomography scan, which was suspected to be metastatic lung disease. The patient underwent a thoracoscopic resection of the nodule. The histopathological examination of the specimen confirmed it to be myeloid osseous metaplasia. The disease usually has no significant complications and can also be found in association with other pulmonary diseases. Very limited information is available on the phenomenon; therefore, there is no exact treatment guide for clinicians to follow. In conclusion, myeloid osseous metaplasia of the lung is a rare finding, and based on this report, it may be associated with TCC.

Extra­abdominal recurrent aggressive fibromatosis: A case series and a literature review.

Aggressive fibromatosis is a rare clonal proliferative tumor arising from mesenchymal cells in the fascia and musculoaponeurotic structures. The aim of the present study was to describe several cases of extra-abdominal recurrent aggressive fibromatosis. The present study was a single-center retrospective case series of patients with recurrent aggressive fibromatosis. The cases were managed at a single private facility. A total of 9 patients with recurrent fibromatosis were included. The mean and median ages of the patients were 29 and 30 years, respectively. In total, two thirds (66.67%) of the cases were female. A negative previous medical history was reported in 7 cases (77.7%), and diabetes and hypertension were reported in 1 case (11.1%). Overall, only 1 case (11.1%) had a family history of breast fibromatosis. The time interval between primary tumor resection and recurrent presentation was 28 months. In 6 cases (66.7%), the tumor was located in the extremities. Pain was the most common presenting symptom in 6 cases (66.7%). All patients had their recurring tumor surgically removed, followed by radiation in 5 cases. The resection margin was positive in 4 cases (44.4%). Each patient was subjected to a careful three-month follow-up for recurrences. On the whole, the present study demonstrates that despite the fact that several therapeutic approaches for extra-abdominal recurrent aggressive fibromatosis have been described in the literature, there is a significant likelihood of recurrence following resection.

Spermatocytic tumor of the testis: A case report and mini­review of the literature.

Spermatocytic tumors are a rare type of testicular cancer, comprising <1% of all testicular malignancies. This type of cancer typically affects males in their 60s and 70s and rarely metastasizes; however, it poses a threat to the health of affected individuals if left untreated. The present study describes the case of a 68-year-old male patient with this type of tumor, including a presentation of his initial symptoms, treatment and subsequent monitoring. A male patient, aged 68 years, visited the authors' clinic with an asymptomatic mass in the right testicle. The mass had been progressively increasing in size for a duration of 5 years following a history of blunt injury. During the examination, a noticeable, painless enlargement was detected in the right testis, whereas the left testis appeared to be in a normal state. Tumor markers were within normal limits. Imaging revealed a complex mass (11x8x7 cm) almost replacing the right testis, with no detectable lymph nodes. A right radical orchidectomy was performed under spinal anesthesia. A histopathological examination revealed a spermatocytic tumor. The post-operative period was uneventful, with no metastasis detected in the CT scans. The patient was discharged with instructions for regular follow-up appointments. The case presented herein highlights a rare spermatocytic tumor in a 68-year-old male. The early detection and treatment of testicular tumors, regardless of age, are crucial for a good prognosis.

Challenges and successful management of subglottic tracheal stenosis in a 2­year­old child: A case report and a mini­review of the literature.

Tracheal stenosis is a narrowing of the windpipe that can lead to shortness of breath, stridor and even suffocation. The present study reports the clinical course of a patient with this condition in an aim to help clinicians obtain more information about this rare condition and identify potential treatment options. A 2-year-old female child presented with progressive shortness of breath and stridor. She was initially managed with tracheostomy; however, this was unsuccessful in relieving the stenosis. Subsequent interventions, including rigid bronchoscopy and dilatation were successful in relieving the condition. A benign hypertrophy of the bronchial wall was identified through biopsy. The patient was treated with steroids and antibiotics, and she experienced a marked improvement in symptoms and remained asymptomatic after a 1-year follow-up. Tracheal stenosis is a rare, yet serious condition that may be life-threatening. Thus, the early diagnosis and treatment of this condition are essential in order to improve outcomes.

Prognostic factors in renal cell carcinoma: A single­center study.

Renal cell carcinoma (RCC) is a heterogeneous and complex disease with numerous pathophysiologic variants. ~40% of patients succumb due to the progression of the disease, making RCC the most fatal of the common urologic malignancies. Prognostic factors are indicators of the progression of the disease, and the precise determination of these factors is important for evaluating and managing RCC. In the present study, it was aimed to determine and find associations among the histopathological features of RCCs and their impact on survival and metastasis. This is a cross-sectional study of RCC cases who have undergone partial or radical nephrectomy from March 2008 to October 2021 and have been pathologically reviewed at Shorsh General Teaching Hospital in Sulaimani, Iraq. The data in the pathology studies were supplemented by follow-up of the patients to obtain information about survival, recurrence and metastasis. In total, 228 cases of RCC were identified, among whom 60.5% were men and 39.5% were women, with a median age of 51 years. The main tumor types were clear cell RCC (71.1%), papillary RCC (13.6%), and chromophobe RCC (11%). Various measures of aggressiveness, including tumor necrosis, sarcomatoid change, microvascular invasion, and parameters of invasiveness (invasion of the renal sinus and other structures), were significantly correlated with each other, and they were also associated with reduced overall survival and an increased risk of metastasis on univariate analysis. However, on multivariate analysis, only tumor size and grade, and microvascular invasion retained statistical significance and were associated with a lower survival rate. In conclusion, pathological parameters have an impact on prognosis in RCC. The most consistent prognostic factors can be tumor size and grade, and microvascular invasion.

Resectability in bronchogenic carcinoma: A single­center experience.

Bronchogenic carcinoma comprises >90% of primary lung tumors. The present study aimed to estimate the profile of patients with bronchogenic carcinoma and assess the cancer resectability in newly diagnosed patients. This is a single-center retrospective review conducted over a period of 5 years. A total of 800 patients with bronchogenic carcinoma were included. The diagnoses were mostly proven with either cytological examination or histopathological diagnosis. Sputum analysis, cytological examination of pleural effusion and bronchoscopic examination were performed. Lymph node biopsy, minimally invasive procedures (mediastinoscopy and video-assisted thoracoscopic surgery), tru-cut biopsy or fine-needle aspiration was used to obtain the samples for diagnosis. The masses were removed by lobectomy and pneumonectomy. The age range was between 22 and 87 years, with a mean age of 62.95 years. Males represented the predominant sex. Most of the patients were smokers or ex-smokers. The most common symptom was a cough, followed by dyspnea. Chest radiography revealed abnormal findings in 699 patients. A bronchoscopic evaluation was performed for the majority of patients (n=633). Endobronchial masses and other suggestive malignancy findings were present in 473 patients (83.1%) of the 569 who underwent fiberoptic bronchoscopy. Cytological and/or histopathological samples of 581 patients (91.8%) were positive. Small cell lung cancer (SCLC) occurred in 38 patients (4.75%) and non-SCLC was detected in 762 patients (95.25%). Lobectomy was the main surgical procedure, followed by pneumonectomy. A total of 5 patients developed postoperative complications without any mortality. In conclusion, bronchogenic carcinoma is rapidly increasing without a predilection for sex in the Iraqi population. Advanced preoperative staging and investigation tools are required to determine the rate of resectability.

Synchronous Kaposi sarcoma and renal cell carcinoma in an elderly male patient (a very uncommon reported entity): A case report.

Based on the literature, there are only three reports available to date on synchronous Kaposi sarcoma (KS) and renal cell carcinoma (RCC), at least to the best of our knowledge. The present study reports a rare case of synchronous classic KS and clear cell RCC. A 69-year-old male presented with painful, purplish nodular lesions on the dorsal aspect of his hands and feet. He had no chronic medical illnesses or prior surgical interventions. An excisional biopsy of one of the lesions revealed a nodular dermal lesion with numerous vascular channels and interlacing spindle cells. A 2.5 cm-enhancing mass was found in a contrast-enhanced computed tomography scan of the abdomen, suggesting RCC or metastasis. A partial nephrectomy was performed, and the histopathological findings were consistent with clear cell RCC. The patient responded well to paclitaxel and topical imiquimod (5%), and the skin lesions disappeared. Both KS and RCC are vascular tumors, and their pathogenesis is commonly affected by an angiogenic factor known as vascular endothelial growth factor (VEGF). A complete response of KS was observed after sorafenib, an inhibitor of VEGF receptors, was administered for the treatment of metastatic renal cancer. This reinforces the fact that there is a common therapeutic and pathogenetic pathway between these two neoplasms. Synchronous KS and clear cell RCC are rare findings. Their simultaneous appearance may be triggered by the common enhancing angiogenic factor, VEGF.

Whole­body MRI for metastatic workup in patients diagnosed with cancer.

Early diagnosis and appropriate staging workup are crucial for cancer patients. Whole-body magnetic resonance imaging (WB-MRI) has been proposed as another practical whole-body approach for assessing local invasiveness and distant metastases in patients newly diagnosed with cancer. The current study aimed to evaluate the efficacy of WB-MRI in assessing metastasis in patients newly diagnosed with cancer using histopathologic data as the reference method. A prospective observational study was performed from April 2018 to July 2020. MRI sequences were utilized to acquire anatomical and functional images in three orthogonal planes. The discovery was classified as nodal, skeletal and visceral metastases. Patient-based analysis was used for visceral metastasis and region-based for skeletal, systemic and lymph node metastases. A total of 43 consecutive patients (mean age, 56±15.2 years) were assessed successively. In 41 patients, there was a concordance between the WB-MRI and histological confirmation. The most prevalent site of metastasis was the skeletal system (18 patients). There were 12 individuals with liver metastasis, 10 with lung metastasis and 4 with peritoneal metastasis, with just one brain metastatic lesion found. On WB-MRI, 38 lymph node groups were deemed positive. Out of the total, 66 skeletal locations contained metastases. The accuracy of WB-MRI for nodal, skeletal and visceral metastases was (98.45, 100 and 100%, respectively). In conclusion, WB-MRI in three orthogonal planes, including the diffusion-weighted MRI with background body signal suppression sequence, may be utilized efficiently and accurately for assessing metastasis staging and may thus be utilized in patients with newly diagnosed cancer.

Renal cell carcinoma T staging: Diagnostic accuracy of preoperative contrast-enhanced computed tomography.

Renal cell carcinoma (RCC) accounts for 1-2% of all malignancies and is the most common renal tumor in adults. Imaging studies are used for diagnosis and staging. Tumor-Node-Metastasis staging strongly affects prognosis and management, while contrast-enhanced computed tomography (CECT) is regarded as a standard imaging technique for local and distant staging. The present study aimed to evaluate the accuracy of CECT for the preoperative staging of RCC by using surgical and pathological staging as the reference methods. This single-center prospective study was conducted between October 2019 and November 2021. The preoperative abdominal CT scans of patients suspected of having RCC were reviewed. Imaging data were collected, including tumor side and size, and perinephric fat invasion. Intraoperative notes were recorded, including the operation type, perinephric fat invasion, renal vein (RV) or inferior vena cava (IVC) tumor extension, and surrounding organ invasion. pathological data were collected on tumor size, RCC type, presence of clear margins, presence of renal capsule or perinephric fat invasion, renal sinus or pelvicalyceal system (PCS) invasion, segmental or main RV extension, and the involvement of Gerota's fascia and nearby organs. Preoperative CECT revealed that 42 out of 59 tumors had a greater maximum diameter than the pathological specimen, with an overall disparity of 0.25 cm. The specificity of CT for the detection of tumor invasion of the perinephric and renal sinus fat and PCS was 95%, and the sensitivity ranged from 80 to 88%. CT had an 83% sensitivity and a 95 specificity in detecting T4 stage cancer, with a 100% specificity for adrenal invasion. The concordance between radiographic and histological results for RV and IVC involvement was high, with specificities of 94 and 98%, and sensitivities of 80 and 100%, respectively. Overall accuracy for correct T staging was 80%. In conclusion, CECT is accurate in the local T staging of RCC, with high sensitivity and specificity for estimating tumor size and detecting extension to nearby structures and venous invasion.
