Backgroundporocarcinoma is a rare sort of skin cancer developing from sweat glands. Its clinical course and management are not well understood.Objectivesthe current meta-analysis is to address the presentation and management of porocarcinoma.Data sourcesWeb of Science, PubMed, MEDLINE on OVID and Google scholar were searched for English-language studies published before December 1, 2016.ResultsThe review of literature revealed 453 cases. From which 222 (49%) cases were male and female were 231 (51%). The mean age was 67.57 years. The mean duration of presentation was 5.57 years ranging from 4 days to 60 years of age. The most common site of affection is the head and neck (39.9%) followed by lower extremity (33.9%). Mass and nodule are the most common modes of presentation. Metastasis occurred at presentation in 110 (31%) cases. The most common organ to which porocarcinoma metastizes is the nearby lymph node (57.7%).ConclusionsPorocarcinoma is an aggressive skin cancer. Surgery is the main modality of treatment.Systematic review registration numberreviewregistry233.

Objective The incidence of thyroglossal duct diseases in the general population is about 7%. We aimed to demonstrate the clinical presentations and management of thyroglossal duct diseases. Methods We conducted a retrospective review of all patients who underwent surgery for histopathologically confirmed thyroglossal duct cyst, sinus, or fistula at a single center. Results A total of 151 cases were included in this study. There were more female patients (87, 58%) than male patients (64, 42%). The patients’ ages ranged from 1 to 63 years old. The most prevalent complaint was painless upper midline neck swelling (93.3%). Most cases were diagnosed as thyroglossal duct cysts (137, 90.7%). Six cases (4%) were associated with carcinoma. All the cases were managed using the modified Sistrunk procedure. There were no procedure-related complications, and five cases of recurrence. Conclusions Although thyroglossal duct cyst is the most common neck anomaly in children, it may also present with various characteristics later in life. This condition can be managed successfully without complications and with a low recurrence rate.

Objective This study was performed to report and analyze the prevalence of permanent facial nerve paralysis following parotidectomy for various benign and malignant lesions in a single center. Methods This single-center retrospective study included all patients who underwent parotidectomy (total and superficial) for benign and malignant tumors and chronic inflammatory diseases during a 6-year period. Patients who had previously undergone an operation of the parotid gland and those with preoperative facial weakness were excluded. Results The study included 127 patients ranging in age from 14 to 83 years (median, 45.89 years). Most patients were female (n = 83, 65.4%). The most prevalent procedure was superficial parotidectomy (n = 117, 92.1%), followed by total parotidectomy (n = 6, 4.7%). The average operative duration was 138 minutes (range, 80–400 minutes). Histopathology revealed that 109 (85.8%) patients had benign tumors, 14 (11.0%) had malignant tumors, and 4 (3.1%) had chronic sialadenitis. Only two patients sustained an injury to the cervical branch of the facial nerve. Conclusion In this single-center experience of parotid surgery, the rates of transient and permanent facial paralysis were acceptably low at 9.0% and 1.6%, respectively, for all pathologies.

Introduction: Reoperation is the most challenging task in thyroid surgery because of the high risk of complications. This study aims to demonstrate the efficacy of a modified thyroidectomy technique in decreasing associated complications to almost zero in recurrent thyroidectomy. Methods: This single-group cohort study enrolled consecutive patients who had a recurrent thyroidectomy. The patients were examined for vocal cord motility preoperatively. The procedures were done by high-volume surgeons using a modified thyroidectomy technique, which included the following steps:1) Finding and preserving parathyroid glands before searching for the recurrent laryngeal nerve; 2) Expecting the recurrent laryngeal nerve in any area of the neck until it is found; 3) Starting the dissection in the suprasternal notch to find the recurrent laryngeal nerve in the tracheoesophageal groove; 4) If the nerve was not found in the suprasternal notch, the search would continue at the nerve's expected entrance to the cricoid cartilage. Results: In total, 195 cases with redo thyroidectomy were enrolled in this study. Female patients (173, 88.7%) were predominant compared to males (22, 11.3%). The most common ultrasonographic finding was multinodular goiter in 138 cases (70.7%). Most of the cases underwent total thyroidectomy (160, 82%), and thyroid lobectomy was performed in 35 cases (18%). In all the cases that underwent total thyroidectomy, both recurrent laryngeal nerves were explored, and the concerned lateral recurrent laryngeal nerve was seen during the thyroid lobectomies. There was no injury to recurrent laryngeal nerves, and only 15% of the cases suffered from temporary hypocalcemia. Conclusion: Recurrent thyroidectomy without significant complications is possible when conducted by high-volume surgeons, and a modified technique is used.
