Epstein-Barr virus-positive anaplastic plasmacytoma in the sinonasal tract is uncommon. Herein, we present the case of a 40-year-old male patient with a right sinonasal tract filled with a soft tissue mass, as shown on CT. Apart from frequent nosebleeds, he did not report any specific sinonasal symptoms, such as nasal obstruction, discharge, or loss of smell. The patient underwent functional endoscopic sinus surgery under general anesthesia. The diagnosis of Epstein-Barr virus-positive anaplastic plasmacytoma was confirmed by lesion biopsy, subsequent immunohistochemical staining, and in situ hybridization.

After removal of a large frontal sinus osteoma in this case, the contralateral nasofrontal canal was opened to drain the intraoperative fluid and prevent infection, and the defect in the orbitofrontal area was restored using a titanium mesh designed with 3D printing technology.

True thymic hyperplasia results from stressful situations such as chemotherapy. It commonly presents as an anterior mediastinal mass; cervical location is exceptional. Here we report a case of a cervical true thymic hyperplasia in a 12-year-old girl who had a Hodgkin lymphoma treated by radiotherapy and chemotherapy. She was referred to our department for a left cervical mass. The PET scan showed a hypermetabolic adenopathy. Mediastinal MRI was unremarkable. The patient underwent resection of the cervical mass under general anesthesia. Pathological examination confirmed the diagnosis of a true thymic hyperplasia. The aim of this paper is to illustrate a case of an incidental ectopic cervical thymic hyperplasia in a patient treated for Hodgkin lymphoma.

Adenoid cystic carcinoma (ACC) of the sublingual gland is rare. There are no previous reports of the metastasis of sublingual gland ACC to the upper gingiva. Herein, we report the first case of a patient with metastasis of sublingual gland ACC to the upper gingiva. It should be recognized that although metastasis of sublingual gland ACC to the upper gingiva is very rare, it can occur.

The occurrence of ectopic intrathyroidal parathyroid adenoma (EPTA) is very rare, which causes some difficulties in diagnosis and complicates treatment. In addition, the occurrence of EPTA with nodular goiter (NG) is rare, which makes diagnosis difficult and requires the assistance of clinical evidence, imaging data, and cytological examination results. Therefore, we present a patient with a final diagnosis of ETPA with NG.

Immunoglobulin G4-related disease (IgG4-RD) is a novel clinical disease entity characterized by elevated serum IgG4 concentration and tumefaction or tissue infiltration by IgG4+ plasma cells.¹ We report the case of a 56-year-old man who presented with nasal obstruction for 5 years. Rhinoscopy revealed hypertrophy and sclerosis of the inferior turbinate, whereas computed tomography revealed inflammation of the anterior ethmoid sinus and frontal sinuses. An endoscopic inferior turbinectomy was performed, and IgG4-RD was definitively diagnosed based on the histopathological features of the turbinate tissue. Prednisolone was administered postoperatively. IgG4-RD presenting with hypertrophy and sclerosis of the inferior turbinate is rare. Awareness of IgG4-RD originating in the sinonasal cavity is essential to avoid delayed diagnosis.

Parathyroid cyst is a rare entity that can closely mimic thyroid and brachial cleft cysts, particularly when located within the thyroid gland. Most commonly, the cysts are non-functional but can produce compressive symptoms. The cyst contains watery content with elevated PTH levels, specifying parathyroid origin¹. Parathyroid cysts should be considered in the differential in patients with a neck mass. This study describes a rare case of a middle-aged woman with a history of a symptomatic intrathyroidal parathyroid cyst discovered intraoperatively.

Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis (MTB), can affect the lungs (pulmonary TB) as well as other sites (extrapulmonary TB). Nasopharyngeal tuberculosis (NPTB) is a rare type of extrapulmonary TB. Since NPTB has nonspecific clinical presentation with low index of suspicion, it is difficult for clinicians to make an early diagnosis and proper treatment. We recently encountered a 42-year-old woman with NPTB concomitant with middle ear TB, which strongly mimicked nasopharyngeal carcinoma. Since the diagnosis of NPTB was difficult to confirm based on endoscopic findings and imaging studies, this patient underwent nasopharyngeal biopsy, and finally, polymerase chain reaction (PCR) confirmed NPTB. This report describes our NPTB case as well as summarizes all cases of NPTB reported in South Korea. We highlight that active tissue biopsy with antibacterial smear and additional PCR or specific TB blood test should be considered for cases with high suspicion of NPTB.

Hamartomas are common in the lung, kidney, liver, spleen, and, but rare, in the sinonasal tract. Respiratory epithelial adenomatoid hamartomas (REAHs) are benign lesions common in men aged 30 to 90 years. Approximately 70% of REAHs in the head and neck region originate from the posterior nasal septum. We present an unusual case of REAH originating from the maxillary sinus and extending to the nasopharynx of an adolescent boy.A 17-year-old boy without any salient medical history presented to our department with nasal obstruction that had persisted for 7 years as well as greenish nasal discharge, hyposmia, and a complaint of fetid smell. Sinoscopy of the osteomeatal complex (OMC) revealed bilateral mucopus and a large right polypoid tumor extending into the nasopharynx. Computed tomography of the paranasal sinuses revealed soft-tissue opacification around the right OMC, frontal sinus, ethmoid sinus, maxillary sinus, and nasopharynx. We performed bilateral endoscopic sinus surgery. REAH and chronic rhinosinusitis with nasal polyps were diagnosed on the basis of a pathology report. No evidence of recurrence was observed by 6 months after surgery, and his hyposmia, nasal obstruction, and purulent nasal discharge were alleviated considerably. Accurate diagnosis based on pathology is essential for determining the optimal treatment, which for REAH is complete surgical excision.

Background: Recently, endoscopic endonasal approaches (EEA) have been used for skull base defect reconstruction surgeries. The nasoseptal flap (NSF), a vascular pedicled flap, was introduced to decrease postoperative cerebrospinal fluid (CSF) leakage.

Purposes: This study aimed to outline the authors' institutional experience using NSF and rigid implants in anterior skull base defect reconstruction surgeries following EEA.

Design: A retrospective cohort review of patients who underwent NSF reconstruction following EEA in the Otorhinolaryngology and Neurosurgery Departments at King Saud University Medical City, Riyadh, Saudi Arabia, from January 2015 to May 2021, divided into 2 time periods according to the reconstruction technique.

Result: Out of the 106 patients who underwent EEA, 77 underwent NSF reconstruction. The majority had expanded EEA (94.8%). The mean age was 40.21 ± 17.7 years, and the female gender represented 61% of the sample. More than half of the sample underwent right NSF (57.1%). Meningioma was the most common diagnosis (45.5%). The clivus was the most frequent site of lesions (23.4%). The overall rate of postoperative CSF leakage and lumbar drainage (LD) insertion was 15.6% and 51.9%, respectively. The duration of LD was a median of four days. The overall failure rate was 13%, declining from 20% in the first period to 5.4% in the second period. Rigid implants were used significantly more in the first period than in the second period (67.5% versus 16.2%, P < 0.001). Meningitis, the highest postoperative complication, was reported in 6 patients (7.8%). One patient died three weeks postoperatively after massive nasal bleeding. No significant difference was found between either side of the NFS regarding the CSF leakage and failure rate.

Conclusion: In the authors' experience, there has been an overt decline in failure rates and complications of EEA over the last three years due to increased experience among surgeons and a standardization of reconstruction techniques. Minimal reconstruction may provide satisfactory results by decreasing the use of rigid implants. An endoscopic endonasal approach with an NSF for anterior skull base defect reconstruction is considered a safe procedure with no significant difference between the sides of the flap.
