RESUMEN
Sebaceous carcinoma is extremely rare in the parotid gland. Recently, we experienced a case of carcinoma with sebaceous differentiation arising from the parotid gland in patient who was diagnosed as parotid adenoma carcinoma and underwent total parotidectomy.A 73-year-old male visited our department for the evaluation of 3-month history of infra-auricular mass combined with pain. Radiologic finding showed lobulated enhancing and solid mass with calcification in the right parotid gland. Initially, total parotidectomy with supraomohyoid neck dissection was performed. Pathological findings showed capsulated whitish mass with hemorrhage and cystic degeneration. Immunohistochemically, CK7, CK5/6, p63 were positive and CEA was negative. The intra-operative frozen section diagnosis was mucoepidermoid carcinoma. The permanent diagnosis was changed to adenocarcinoma, NOS(not otherwise specified). Fourteen months later, the newly developed mass was noticed on the operation bed. The mass was clinically diagnosed as recurred adenocarcinoma. Revision parotidectomy was performed and pathological findings revealed that the tumor was newly developed sebaceous carcinoma. We report a case of carcinoma with sebaceous differentiation in parotid gland with a review of literature.
RESUMEN
Background and Objectives@#Recurrent epistaxis requiring emergency department (ED) visits results in increased morbidity in the elderly and associated with high health care costs. This study is to analyze the frequency and characteristics of epistaxis patients in the elderly and to find out the risk factors and effective treatment for recurrent epistaxis. Subjects and Method We studied retrospectively the clinical cases of 977 emergency patients and 155 patients, aged over 65, for the treatment of epistaxis during the last 10 years from January 2008 to January 2018. The group A, comprised of 95 patients (68.29%), was treated with an initial treatment. The group B, which comprised of 60 patients (38.71%), visited for re-bleeding following an initial treatment. @*Results@#Patients made 2 to 10 ED visits due to re-bleeding and 32 of the 60 patients (53.5%) visited twice. The electrocauterization was the most common (61.7%) for treatment method during rebleeding, followed by posterior packing (18.3%). The factors that increases the risk of recurrent epistaxis are anticoagulants, posterior epistaxis, anterior packing, inefficient ED packing. There was no correlation between comorbidities and rebleeding. @*Conclusion@#Accurate medical history taking of anticoagulants may enable personnel to provide more effective management of these patients. The most important factors in the failure of primary care were not being able to find the precise area of bleeding and ineffective packing during the initial treatment. Therefore, it is important that we must carefully check the areas using the endoscope to decrease the failure of initial treatment of epistaxis.
RESUMEN
Nontuberculous mycobacteria (NTM) is commonly found in the surrounding environment and can cause opportunistic infection. Mainly, it causes lymph node infection in the cervical area, which is often known to occur in children. Recently, we have experienced a case of NTM infection on a branchial cleft cyst in a 36-year old male. NTM was diagnosed by fine needle aspiration and branchial cleft cyst was confirmed by postoperative pathologic findings. We report this case with a review of literature.
RESUMEN
Background and Objectives@#There has been a long debate on whether intraoperative parathyroid hormone (IOPTH) monitoring is mandatory or not in the excision of a single abnormal parathyroid gland. The aim of this study is to suggest a new criteron of IOPTH monitoring. Subjects and Method We retrospectively analyzed 31 patients who underwent parathyroidectomy from 2005 to 2019. Patients had IOPTH not measured and those with secondary hyperparathyroidism were excluded. IOPTH was measured preoperatively (EX00), at 10 minutes (EX10) and 20 minutes (EX20) after the excision and analyzed. We determined the surgery as a ‘successful excision of lesion (SEOUL)’ when it met the following criteria: criterion 1) the level of EX10 or EX20 decreased under the upper normal or under upper limit of parathyroid hormone (65 pg/mL); criterion 2) EX20 decreased below 50% of EX00 and less than 195 pg/ mL (3 times the upper normal limit); criterion 3) multiglandular disease. @*Results@#Twenty-five patients among 31 patients were included this study (M:F=8:17). Twenty- two patients were suspected of single lesion and three patients of multiple lesions on preoperative images (99mTc-sestamibi scan, neck CT, and PET-CT). IOPTH of EX00, EX10, and EX20 were 488.92±658.74, 121.36±134.73, and 92.44±111.55 pg/mL, respectively. Sixty-four percent patients (16/25) met the criterion 1. Six patients (24%) successfully excised a lesion meeting the criterion 2. Three patients had multiglandular disease, meeting the criterion 3. @*Conclusion@#Our new criteria suggest when we could stop the procedure. If the level of IOPTH does not meet the SEOUL criteria, it means that there might be more lesions.
