Pyriform sinus fistula (PSF) is an anomaly that can arise due to failure of involution of the third or fourth branchial cleft during embryogenesis. It can manifest clinically as sinuses, cysts, or abscesses in the neck and is common in childhood. Herein, we describe a neonate who presented with neck swelling and respiratory distress, which was secondary to a fourth branchial pouch sinus. Physical examination revealed swollen areas in the posterolateral pharyngeal wall and on the external left side of the neck. Computed tomography imaging showed a left-sided mass that was filled with air and fluid. Eventually, the pyriform sinus cyst and the entire fistulous tract were excised. The postoperative course was uneventful. Follow-up after 18 months showed no recurrence.

Objectives. Pyriform sinus fistulae arise from disturbances in the development of the fetal third and fourth branchial pouches and are predominantly found on the left side. We report the rare case of a right-sided pyriform sinus fistula presenting as a lateral neck abscess.Study Design. Case report.Methods. A 24-year-old woman presented with a two-week history of right-sided neck abscess. A fluoroscopic sinogram revealed a fistulous tract extending from the abscess to the apex of the right pyriform sinus. It was determined that the fistula was likely a third or fourth branchial remnant, a rare right-sided finding. Chemocauterization of the fistulous tract with 40% trichloroacetic acid was used to successfully treat the patient.Results. Approximately 93–97% of branchial pouch anomalies are left sided. Treatment options include surgical excision and cauterization.Conclusions. Branchial cleft cyst and pyriform sinus fistula must be considered in the diagnosis of cervical abscess in either side of the neck.

Collaural fistula is a very rare Work Type II first branchial cleft anomaly in which there is a complete fistulous tract between external auditory canal and the neck. Misdiagnosis and mismanagement can lead to prolonged morbidity and complications due to repeated infections. We present a case of an 18-year-old lady with a recurrent discharging sinus on her neck for 4 years. She has been treated with repeated incision and drainage and multiple antibiotics in the past. Otoscopic examination revealed an opening on the floor of the left external auditory canal. A diagnosis of an infected collaural fistula was made. Complete excision of the fistulous tract was done after treatment of the active infection. On follow-up, there was no further recurrence at 1 year. Sound knowledge of embryology of branchial anomalies with good history and examination is important to make correct and early diagnosis to prevent morbidity.

Idiopathic thrombocytopenia (ITP) is a bleeding disorder involving the destruction of platelets by the immune system. Systemic amyloidosis is another bleeding disorder involving amyloid deposits that create defects in coagulation and increased prothrombin and thrombin times. We report a 52-year-old man with ITP and new two-month-duration, painless gross hematuria without clot formation resulting in amyloidosis involving the ureterovesical area of the bladder. He had osteopenia, hypertension, and moderate thrombocytopenia due to ITP diagnosed 7 years previously. Cystoscopic examination with urine cytology and computed tomography imaging detected a 2-cm protruding solid bladder mass involving the left ureteral orifice and trigone and left mild hydroureteronephrosis, suggesting bladder cancer. Transurethral resection of the bladder mass was performed to confirm amyloidosis involvement in the ureterovesical junction of the bladder and ureter. Four weeks postoperatively, intermittent gross hematuria remained; hence, left ureteroneocystostomy was performed. Regular follow-up showed no signs of hematuria or intravesical recurrences for 14 months.

Background: Adrenal schwannomas (AS) are extremely rare neoplasms. This study shares our experience regarding the diagnosis and operative management of AS. Methods: Clinical details, radiologic, laboratory, and pathologic findings as well as follow-up data were analyzed retrospectively for 13 AS patients who accepted surgery at a tertiary referral hospital in China between January 1, 1996, and December 31, 2017. Results: The mean age of the patients at diagnosis was 44.7 ± 13.7 years (range 19–62 years; male: female ratio, 1:1.16), of whom 7 patients had unilateral AS on the right side, and the remaining 6 on the left side. None of the cases were hormonally active. None of the 13 cases were diagnosed as AS by computed tomography imaging before the operation. Among the patients, 10 were asymptomatic. The mean preoperative size was 7.1 ± 3.2 cm (range 1.6–12.6 cm). All patients underwent surgery, with open adrenalectomy in 5 patients and laparoscopy in 8 patients. The mean tumor size on pathologic examination was 6.8 ± 3.0 cm (range 3.0–11.7 cm). The surgical specimens were confirmed by pathological examination. During a median follow-up of 60.8 ± 17.7 months, no patients showed recurrence or metastasis. Conclusion: The preoperative diagnosis of AS remains difficult despite the advances in imaging examinations. After complete resection, the prognosis of AS is excellent.

Pathological Report

We introduce a case report of an adult male diagnosed with non-syndromic pheochromocytoma with a first pathological post-operatory report of malignant type with further re-considerations during follow-up for a 6-year period of time. This is 46 - year old male admitted for: post-adrenalectomy status reassessment. In 2013 he was diagnosed with high blood pressure requiring a complex regime of anti-hypertensive drugs to control it. In 2015 he was referred for an endocrine check-up which revealed a pheochromocytoma (noradrenaline type). Computed tomography imaging of the abdomen showed a right adrenal tumor of 28/38 mm, a mass that was clearly contoured, with heterogeneous pattern, and with moderate caption of intravenous contrast. Laparoscopic right adrenalectomy is performed with normalization of high pre-operatory normetanephrines and a dose reduction of anti-hypertensive medication which was still necessary. Pathological report suggested a malignant pheochromocytoma; the initial PASS score of 8 was later re-calculated, and a GAPP score of 5 was achieved showing a moderately differentiated tumor. No genetic backup was identified. Within the first year after tumor removal, the patient suffered a stroke, proving the higher cardiovascular risk than general population even after hormonal imbalance is restored. Lifelong surveillance is the rule.

Abstract BACKGROUND Routine colonoscopy is recommended to determine the coexistence of colon cancer after medical treatment for colon diverticulitis. However, in the case of uncomplicated diverticulitis diagnosed by computed tomography imaging, the clinical relevance of routine follow-up colonoscopy has recently been debated. Yet, the role of follow-up colonoscopy for right colon diverticulitis, which tends to develop at a younger age than left colon diverticulitis, has not been specifically evaluated. Therefore, or aim in this study was to evaluate the incidence of colon cancer, detected by routine colonoscopy, after conservative management of acute uncomplicated right colon diverticulitis. METHODS Included were patients with uncomplicated right colon diverticulitis (modified Hinchey stage Ia) diagnosed by computed tomography imaging, between 2011 and 2017, and who underwent follow-up colonoscopy surveillance after treatment. The primary outcome was the incidence of colon cancer, with the detection rate of adenoma being the secondary outcome. Information for analysis was retrieved, retrospectively, from patients’ medical records. RESULTS The study group included 330 consecutive patients, with a mean age of 41.9 years, and 51.9% being men. For the primary outcome, the rate of colon cancer on follow-up colonoscopy was 0.3% (1/330 cases). The rate of adenoma detection was 20.3% (67/330 cases), with advanced adenoma identified in 9 of these cases (13.4%). CONCLUSION In patients with acute uncomplicated right colonic diverticulitis, routine colonoscopy after conservative treatment may not be necessary.
