  Anuja Dharap and Steven Kin

  Publication Date: 5-2022

  Introduction

  • Aneurysmal bone cysts (ABC) are rare non-neoplastic; locally destructive growth
  • Most commonly found in long bones with 2-6% incidence of appearing in the head and neck
  • 14 cases in literature of ABCs emanating from the paranasal sinuses
  • High recurrence rate, up to 40%, in long bones
  • Multiple treatment modalities used to prevent recurrence including: cryotherapy, radiation, curettage, phenol

  Hearing Durability and Trajectory after Radiosurgery for Vestibular Schwannoma

  Christian G. Fritz, Dennis I. Bojrab II, Nathan C. Tu, Christopher A. Schutt, Dennis I. Bojrab, and Seilesh C. Babu

  Publication Date: 5-2-2022

  INTRODUCTION
  Vestibular schwannomas (VS) are benign skull base tumors arising from the eighth cranial nerve. Stereotactic radiosurgery (SRS) is emerging as treatment for smaller sized tumors with the intent being to prevent further tumor growth, thus avoiding mass-effect symptoms. Hearing outcomes are commonly presented as preservation of class A/B hearing (defined as Pure Tone Average (PTA) ≤50 dB with Word Recognition Score (WRS) ≥50 dB). Long-term follow-up data on hearing outcomes and hearing trajectory trends are limited.

  Primary Large Cell Neuroendocrine Carcinoma of Left Tonsillar Fossa: A Case Report

  Jake Sims, Trevor Belavek, and Shant Korkigian

  Publication Date: 5-2022

  Introduction Rare cases of primary neuroendocrine carcinomas (NEC) have been reported in some head and neck structures such as the lingual tonsil, larynx, and major salivary glands.1 However, we report a primary large cell neuroendocrine carcinoma of the tonsillar fossa which has not been previously reported. The World Health Organization (WHO) classifies large cell neuroendocrine carcinoma (LCNEC) as a high-grade, poorly differentiated tumor, with >20 mitotic counts per high power field (HPF) and a Ki-67 index of >20%

  High-Grade (Mammary Analogue) Secretory Carcinoma of the Submandibular Gland: A Case Report and Review of Recent Literature for Diagnostic and Treatment Considerations

  Jake Sims, Zachary Kranz, Erich Schwartz, and Shant Korkigian

  Publication Date: 5-2022

  Introduction

  Mammary analogue secretory carcinoma (MASC) of the salivary glands is a rare tumor that shares immunohistochemical properties as secretory carcinoma of the breast. Classified by the World Health Organization (WHO) in 2017 as secretory carcinoma of the salivary glands.1 This is classically thought of as a low-grade salivary gland lesion that has been historically classified as acinic cell carcinoma (AciCC) or adenocarcinoma, not otherwise specified (NOS).

  Adult High-Grade Head and Neck Cutaneous Rhabdomyosarcoma Misdiagnosed as Low-Grade Atypical Fibroxanthoma on Initial Pathology: A Case Report and Diagnostic Considerations

  Jake Sims, Claire V. Walters, and Shant Korkgian

  Publication Date: 5-2022

  Adult head and neck rhabdomyosarcoma (AHNRMS) is an exceedingly rare soft-tissue sarcoma (STS). We describe a case of AHNRMS that was initially misdiagnosed as atypical fibroxanthoma (AFX). Rhabdomyosarcoma (RMS) is a mesenchymal soft tissue sarcoma that arises from skeletal muscle origin. RMS is most common in the pediatric population, occurring rarely in adults.
