Giant cell tumor of the talus: A case report and literature review.

Introduction And Importance: Giant cell tumor is a benign primary bone tumor of mesenchymal origin that mainly affects the long bones. Involvement of the bones of the foot is rare with an incidence of 1 to 2 %. We report a case of giant cell tumor of the talus in a 36-year-old man.

A rare perspective: fine-needle aspiration cytologic features of hyaline vascular type of Castleman disease: A case report.

Rationale: Castleman disease, also known as Castleman syndrome, is a rare, nonmalignant lymphoproliferative disorder. The localized subtype of this disease is primarily the hyaline vascular type of Castleman disease (HVCD). Although this disease is a benign lesion, the histologic features are similar to those of some malignant lymphomas, so an accurate diagnosis of the disease is required.

Cavernous hemangioma in the masticatory space.

Hemangiomas are benign congenital vascular tumors that commonly arise in the head and neck regions. Although they present with indolent growth and involution in most cases, they can cause facial deformities. Hemangiomas have three subtypes: capillary, cavernous, and mixed.

Intranodal thyroid inclusions revisited: a morphological analysis and application of BRAF VE1 immunohistochemistry.

Aims: The diagnosis of intranodal thyroid inclusions (ITIs) is controversial. We aim to investigate their clinicopathologic features and utilize immunohistochemistry (IHC) to support the diagnosis.

Methods And Results: Forty-one cases of incidentally found ITIs between 2019 and 2023 were categorized into three groups, namely, Group A: thyroidectomy due to papillary thyroid carcinoma (PTC) with regional lymph node dissection (n = 33), Group B: thyroidectomy due to benign thyroid disease with incidental perithyroid lymph node sampling (n = 4), and Group C: surgery due to other head and neck cancers with lateral neck lymph node dissection (n = 4).

Primary Extradural Meningioma: A Systematic Review of Diagnostic Features, Clinical Management, and Surgical Outcomes.

This systematic review consolidates the literature on primary extradural meningiomas (PEMs), a rare subset of meningiomas. We describe the clinical features, management strategies used, and treatment outcomes for published cases. A systematic review was conducted using PRISMA guidelines across multiple databases to 29 July 2024.

Differentiation of Tumors of the Upper Respiratory Tract Using Optical Metabolic Imaging.

Objectives: With over 184,000 new cases and more than 99,000 deaths per year, malignancies of the larynx are a global health problem. Currently, a dedicated screening method enabling a direct onsite diagnosis is missing. This can lead to delayed diagnosis and worse outcomes of the patients.

Angioleiomyomas of the Extremities and Trunk: An Observational Study.

Rationale And Objectives: Angioleiomyomas are benign perivascular tumors that originate from the tunica media of blood vessels. While frequently described in the head, neck, and uterus, angioleiomyomas can manifest in various regions throughout the body. The purpose of this study was to review the history and imaging features of angioleiomyomas of the trunk and extremities.

Performance of image processing analysis and a deep convolutional neural network for the classification of oral cancer in fluorescence visualization.

The aim of this prospective study was to determine the effectiveness of screening using image processing analysis and a deep convolutional neural network (DCNN) to classify oral cancers using non-invasive fluorescence visualization. The study included 1076 patients with diseases of the oral mucosa (oral cancer, oral potentially malignant disorders (OPMDs), benign disease) or normal mucosa. For oral cancer, the rate of fluorescence visualization loss (FVL) was 96.

Mutational analysis of BRAFV600E in a case of sialadenoma papilliferum of oral cavity.

This case report presents a rare benign salivary gland tumour called sialadenoma papilliferum. It comprises 3 to 5% of head and neck tumours and about 1% of all minor salivary gland tumours. The focus is on discussing the BRAFV600E mutation analysis and exploring its clinical implications, along with delving into the histopathological differentials.

Spinal Enchondromas in the Cervical Spine: Rarity, Recurrence and the Importance of Long-Term Surveillance.

Introduction: Chondromas are benign cartilaginous tumors classified into periosteal chondromas and enchondromas. While periosteal chondromas grow on the bone surface, enchondromas develop within the medullary cavity. Enchondromas constitute 4-8% of all bone tumors, with spinal enchondromas being exceptionally rare, particularly in the cervical region.

Office-based flexible endoscopic guided biopsy: single-center feasibility analysis.

Background: Direct laryngoscopy and biopsy have been the standard of care for biopsy of lesions arising from the upper aerodigestive tract (UADT). The requirement of general anesthesia is often a prerequisite. Procedures performed under the laryngeal block and local anesthesia are not viewed as appropriate from the point of view of patient comfort.

Complete surgical resection of a thymic cyst located in the middle mediastinum with extension into the carina through a neck incision: A case report study.

Introduction And Significance: Thymic cysts are rare, located in the middle mediastinum, and are often asymptomatic and discovered incidentally. When they are symptomatic, the symptoms are often due to the effect of the mass, and complete surgical excision is preferred to avoid the risk of complications following their persistence.

Case Presentation: We present a case of a patient who had recurrent dyspnea and was later diagnosed with a cystic formation in the middle mediastinum by radiological investigations and successfully treated through a neck incision and completely resected.

The accuracy of fine-needle aspiration cytology and ultrasonography in assessing thyroid nodules in correlation with histopathology: a retrospective study.

Background: Accurately diagnosing thyroid nodules is vital for preventing unnecessary surgeries and providing prompt therapy. Although fine-needle aspiration cytology (FNAC) and ultrasonography (US) are widely used diagnostic methods, their reliability is questioned. This study investigates the effectiveness of US and FNAC in thyroid nodule diagnosis and differentiates benign from malignant nodules in relation to final histopathological diagnosis.

[Use of clinical ultrasound in primary care: Thyroid nodule].

The thyroid nodule is a frequent lesion within the thyroid. Its incidence is between 50%-60% and most of them are asymptomatic and benign (90-95%) and its diagnosis is frequently made as an incidental finding. The main objective of their study is to rule out thyroid cancer.

External auditory canal chondroid syringoma with bone erosion: A CARE case report.

Introduction: Chondroid syringoma or ceruminous pleomorphic adenoma is a benign mixed cutaneous tumor. It is the second most frequent glandular lesion in the external auditory canal, but no cases associated with bone erosion were found in a PubMed search.

Case Report: The present CARE case report details a chondroid syringoma in the external auditory canal with associated bone lysis, and its management.

Be familiar with benign pediatric head and neck lesions! Image interpretation guides to overcome your weakness.

Pediatric head and neck lesions include three main categories: congenital, inflammatory, and neoplastic. It is important for management to understand the imaging features. The purpose of this pictorial review is to demonstrate the imaging features of benign head and neck lesions of pediatric patients.

External auditory canal osteoma with coexisting canal wall cholesteatoma: a case report and review of literature.

Background: Though rare, benign lesions that usually do not necessitate active intervention, osteomas of the external auditory canal, can be troublesome when they start to produce mass effect and severe obstruction to the external auditory canal. Even more insidious is the rarer phenomenon of canal wall cholesteatomas, which have been known to cause significant canal erosion and if left unchecked and spontaneous destruction of the adjacent anatomical structures, including the facial nerve, temporomandibular joint, sigmoid sinus, and skull base. The occurrence of both these exceptionally uncommon findings in the same canal is an unusual finding and may point to an undetermined interplay in pathogenesis.

[Laryngotracheal Resection and Reconstruction].

Cervical tracheoplasty requires knowledge and skills not only of the trachea but also of the larynx. Even if the lesion is thought preoperatively to be confined to the cervical trachea, intraoperative manipulation of the larynx is often necessary. This area that involves the larynx and trachea is a borderline between otorhinolaryngology and thoracic surgery, and there are very few surgeons in Japan who are well trained in both areas.
