Department of Otorhinolaryngology, University of Health Sciences Turkey, Sisli Hamidiye Etfal Teaching and Research Hospital, Istanbul, Turkey.

We present a case of Giant Cell-Rich Solitary Fibrous Tumor also known as Giant cell angiofibroma, occuring in sublingual region, to our knowledge, which has never been reported before. Forty-nine years old female who presented with painless, slowly growing mass in the sublingual region underwent excisional surgery and was diagnosed with giant cell-rich solitary fibrous tumor previously referred to as giant cell angiofibroma. In our report, we aimed to report the unusual localization of this rare tumor, examine the new nomenclature and classification of giant cell-rich solitary sibrous tumor or giant cell angiofibroma and review the literature regarding head and neck localization of this tumor.

[A Consideration for the Surgical Approach in Laparoscopic Total Pelvic Exenteration after Radiotherapy : A Case Report].

Hinyokika Kiyo 2021 Jan;67(1):31-35

The Department of Urology, Japan Red Cross Wakayama Medical Center.

A 66-year-old woman underwent concurrent chemoradiotherapy (CCRT) for stage IIA cervical cancer. However, two recurrent masses were detected at the vaginal stump 6 years after CCRT, and we performed laparoscopic total pelvic exenteration to obtain a complete cure. Because the terminal ileum appeared white secondary to the effects of radiotherapy, we constructed an ileal conduit using the ileum, approximately 40 cm toward the mouth from the ileocecum.

Development and validation of a contouring guideline for the taste bud bearing tongue mucosa.

Radiother Oncol 2021 04 18;157:63-69. Epub 2020 Nov 18.

Department of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, United States.

Purpose: To introduce a contouring guideline for the taste bud bearing tongue mucosa for head and neck cancer patients receiving radiotherapy.

Pediatric sublingual dermoid and epidermoid cysts: A 20-year institutional review.

Int J Pediatr Otorhinolaryngol 2020 Nov 4;138:110265. Epub 2020 Aug 4.

Department of Otolaryngology-Head and Neck Surgery, University of Colorado School of Medicine, Aurora, CO, USA; Pediatric Otolaryngology, Children's Hospital Colorado, Aurora, CO, USA. Electronic address:

Introduction: Pediatric cystic sublingual masses often present a diagnostic dilemma for practitioners. Though uncommon, dermoid or epidermoid cysts can present in the sublingual space at any age and are often misdiagnosed as an inflammatory pseudocyst (ranula) or lymphatic malformation. Imaging may not always identify the underlying etiology, requiring physicians to maintain a high index of suspicion for these relatively rare oral cysts. Read More

Extraluminal bronchial blocker placement using both nostrils for lung isolation in a patient with limited mouth opening: A CARE-compliant case report.

Medicine (Baltimore) 2020 Aug;99(32):e21521

Department of Anesthesia, Shaoxing University Affiliated First Hospital.

Rationale: The establishment of lung isolation is often particularly challenging for the anesthesiologist in patients with difficult airway. Usually, orotracheal intubation with double lumen tube is the commonly used technique for achieving 1 lung anesthesia. Whereas, in patients with limited mouth opening and restricted cervical mobility, this technique becomes extremely difficult and hazardous. Read More
