Follicular Dendritic Cell Sarcoma of the Thyroid Gland in a Patient with Preexisting Hashimoto's Thyroiditis: A Rare Case Report with a Literature Review.

Thyroid follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy that originates from follicular dendritic cells of the thyroid germinal centers. To the best of our knowledge, there are only 4 reported cases of thyroid FDCS in the English literature. Herein, we present the fifth case of FDCS of the thyroid gland.

Heterotopic SMARCB1-deficient high-grade transformed/dedifferentiated acinic cell carcinoma and sine-qua-non radiology- pathology with TNM challenge.

Heterotopic salivary tissue (HSGT) is found where salivary glands are not normally placed. HSGT manifests as accessory salivary glands, salivary tissue associated with branchial cleft anomalies, and true heterotopic salivary gland tissue. Benign and malignant salivary heterotopias have been described in the literature, with the most common reported neoplasm being Warthin tumor.

[Functional Recovery following Incisional Cheiloplasty for Lower Labial Edema That Developed after Bilateral Neck Dissection and Postoperative Chemoradiotherapy-A Case Report].

We report a case of functional recovery following incisional cheiloplasty for the management of lower labial edema that developed after bilateral neck dissection with preservation of the one-side internal jugular vein and postoperative chemoradiotherapy. An 81-year-old woman underwent partial maxillectomy for the treatment of maxillary gingival cancer(squamous cell carcinoma, cT1N0M0, Stage Ⅰ)in April 2013. In July 2013, she underwent bilateral neck dissection(right, modified; left, radical)for bilateral cervical lymph node recurrence with an extra-nodal spread and received postoperative chemoradiotherapy( CDDP 75 mg/m2×3 course and total radiotherapy dosage of 66 Gy).

Modified nasolabial flap- the nasomentolabial flap: A new arrow in surgeon's quiver.

Aims And Objectives: To describe an inferior extension of a naso-labial flap as an adjunct to a maleo-labial flap in reconstruction of complete thickness defects around the oral commissure in 2 cases that we performed at our institute.

Methods: Two elderly cases of carcinoma buccal mucosa who underwent wide local excision along with neck dissection had moderately large peri-oral defects that are large to cover with nasolabial flap alone. An inferior extension to the maleo-labial flap was added, making it a naso-mento-labial flap to reconstruct the defects with an acceptable outcome aesthetically and functionally.

Mucoepidermoid Carcinomas of the Larynx.

Objectives: Discussions regarding the specific management and outcomes for laryngeal MEC are limited to very small, single-institution case series. To look further into the diagnosis and management of these uncommon non-squamous cell carcinomas of the larynx, we present 3 recent cases of laryngeal MEC treated at our institution.

Methods: Patients at a tertiary hospital treated for MEC between October 2019 and December 2020 were retrospectively identified.

Gravity Assisted Retraction Less Occipito Transtentorial and Trans-Splenial Approach for Posterior Third Ventricular Dermoid.

Background And Introduction: A dermoid is an inclusion cyst. Its presence in the posterior third ventricle is highly infrequent. It usually compresses rather than infiltrates the posterior third ventricle's anatomical structures due to a well-defined capsule.

The Benefit of Postoperative Radiotherapy and Extending Neck Dissection in pT1-2 Oral Squamous Cell Carcinoma With a Single Ipsilateral Cervical Lymph Node Metastasis (pN1).

Background/aim: We compared postoperative radiotherapy (PORT) to surgery only (SO), and supraomohyoidal neck dissection (SOHND) to modified radical neck dissection (MRND) in patients with pT1-T2 squamous cell carcinomas of the oral cavity (OSCC) and a single cervical lymph node metastasis (pN1) in terms of overall survival (OS), oral cancer specific survival (OCSS), and regional recurrence-free survival (RRFS), in a prospective cohort study.

Patients And Methods: We included patients with pT1-T2 pN1 OSCC with no distant metastasis and estimated the survival probabilities using the Kaplan-Meier method and calculated hazards ratios (HR) for PORT vs. SO and MRND vs.

Follicular thyroid carcinoma with an iliac wing metastasis - Rare case report at Bugando Medical Centre in Tanzania.

Thyroid carcinoma is uncommon in our geographical setting. When it occurs the leading histological type is papillary thyroid carcinoma followed by follicular thyroid carcinoma which are differentiated thyroid carcinomas. Differentiated thyroid carcinomas usually have a good prognosis as compared to undifferentiated thyroid carcinomas.

Internal Jugular Venous Extension of a Mandibular Osteosarcoma With Literature Review.

Head and neck osteosarcomas (HNOS) account for less than 1% of all head and neck cancers and makeup 6-10% of all primary osteosarcomas. Mandibular osteosarcomas are the second most common subtype of HNOS. They demonstrate higher recurrence rates; however, are amenable to surgery.

Effect of Prophylactic Central Lymph Node Dissection on Locoregional Recurrence in Patients with Papillary Thyroid Microcarcinoma.

There is a consensus that central compartment lymph node dissection or modified radical lateral neck dissection should be performed in papillary thyroid microcarcinoma (PTMC) patients with lymph node metastases. Prophylactic central lymph node dissection (PCLND) in patients with clinically node-negative (cN0) PTMC to reduce locoregional recurrence (LRR) rate and improve prognosis remains controversial. The present study aimed to analyze the effect of PCLND on LRR and postoperative complications of PTMC in cN0 patients.
