Background Lobular capillary hemangioma is a rare benign tumor, most frequently located in the head or neck region, the nasal cavity being uncommonly affected. Its etiopathogenesis is not fully established, although traumatic and hormonal factors have been implied. Case Description A 50-year-old female patient underwent an uneventful endoscopic transsphenoidal removal of a pituitary cystic macroadenoma at our institution. Nasal packing was used in postoperative hemostasis. Histopathology was compatible with a gonadotrophin-producing adenoma...

Background. Pigmented villonodular synovitis (PVNS) is a rare benign tumor affecting large joints and prompts excision to prevent local destruction of the joint. The purpose of this case report is to describe two differing surgical approaches for management of PVNS of the hip in patients requiring concomitant treatment for additional hip pathology. Methods. This report discusses the presentation, clinical and radiographic findings, and operative management of two contrasting cases of PVNS of the hip. Case 1 describes a 31-year-old female with localized PVNS in addition to a labral tear treated with arthroscopic labral repair followed by tumor excision via a mini-open incision...

Surgery for early-intermediate oropharyngeal squamous cell carcinoma (OPSCC) may involve using transoral endoscopic approaches or open surgical procedures. "Lateral pharyngotomy" (LP) is an open surgical approach that improves exposure of the oropharyngeal region, while avoiding mandibulotomy. The aim of the present study was to retrospectively analyze our experience with the surgical treatment of early-intermediate OPSCC using the LP approach, and to investigate the potentially prognostic clinical and/or pathological factors that might identify patients at higher risk of recurrence after primary surgery...

BACKGROUND: Extranodal (or extracapsular) extension (ENE) is an adverse prognostic factor in patients with head and neck cancers who undergo primary surgery. However, the significance of ENE in human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is not well established, and single-institution studies have not established that ENE predicts inferior outcome. The authors investigated the prognostic value of ENE in HPV-positive patients who underwent primary surgery and whether adjuvant chemoradiation improved overall survival (OS) compared with radiation alone in ENE-positive patients...

INTRODUCTION AND OBJECTIVES: Primary cutaneous angiosarcoma is one of the most aggressive skin tumors and carries a very poor prognosis. Its initially indolent clinical presentation explains the frequently late diagnosis that, together with its typically multifocal pattern and poor delimitation, often makes surgery difficult. The low incidence of primary cutaneous angiosarcoma means that few large single-center series have been published. We review the clinical and pathologic characteristics of cutaneous angiosarcomas treated in our hospital, looking for prognostic factors and for possible diagnostic traits that could facilitate early diagnosis...

BACKGROUND: Solitary large keratoacanthomas (KAs) of the head and neck present a management dilemma, as no reliable means to predict the clinical course is available. Although typically considered a low-grade tumor, KAs are reported to invade/metastasize, prompting more aggressive treatment. There is little published regarding factors that predict when a KA behaves more like an aggressive squamous cell carcinoma (SCC). OBJECTIVE: To study the clinical and pathologic features of large solitary head and neck KAs and assess response to intralesional methotrexate (IL-MTX) as well as predictors of clinical course...

Soft-tissue sarcomas are a diverse group of rare mesenchymal malignancies that can arise at any location in the body and affect all age groups. These sarcomas are most common in the extremities, trunk wall, retroperitoneum, and head and neck. In the adult population, soft-tissue sarcomas arising in the abdomen and pelvis are often large masses at the time of diagnosis because they are usually clinically silent or cause vague or mild symptoms until they invade or compress vital organs. In contrast, soft-tissue sarcomas arising from the abdominal wall come to clinical attention earlier in the course of disease because they cause a palpable mass, abdominal wall deformity, or pain that is more clinically apparent...

PURPOSE: The most appropriate prophylactic antibiotic for clean-and-contaminated head and neck osteomyocutaneous free flap (OFF) tissue transfer procedures is unclear. The purpose of this study was to determine whether the choice of perioperative antibiotic was related to recipient surgical site infection (SSI) in patients receiving an OFF to the head and neck. MATERIALS AND METHODS: This retrospective cohort study evaluated SSI in relation to the perioperative antibiotic received from July 2010 through October 2013 at a tertiary care medical center...

OBJECTIVES: The preoperative diagnosis between serous cystadenomas (SCAs) and mucinous cystadenomas (MCAs) in pancreas is significant due to their completely different biological behaviors. The purpose of our study was to examine and compare detailed contrast-enhanced ultrasonography (CEUS) images of SCAs and MCAs and to determine whether there are significant findings that can contribute to the discrimination between these two diseases. METHODS: From April 2015 to June 2016, 61 patients (35 patients with SCAs and 26 patients with MCAs) were enrolled in this study...

Importance: Resection of the primary tumor with negative margins is the gold standard treatment for squamous cell carcinoma of the oral tongue (SCCOT). A microscopically positive surgical margin is clearly associated with a higher risk for local recurrence, whereas a negative margin has traditionally been defined as greater than 5.0 mm clearance from the tumor, with lesser margins arbitrarily designated as close. The precise cutoff at which the risk for local recurrence with a close margin approximates that of a microscopically positive margin remains unclear...

Metastasis to the head and neck and more specifically to the thyroid gland from distant primary tumors is less common in comparison to the local regional metastasis of squamous cell carcinomas of the upper aero-digestive tract. Preoperative diagnosis of these cases can be difficult. The authors present three cases with distant solitary metastases of clear renal cell carcinoma to the thyroid gland with ambiguous mechanism of tumor spread to the thyroid. Solitary metastases of clear renal cell carcinomas are an uncommon variant of metastasis of this tumor and may imitate thyroid well differentiated carcinoma which most commonly affects the thyroid gland...

OBJECTIVES/HYPOTHESIS: Unlike lymphadenectomy at other sites, there is no discrete lymph node count defining an adequate neck dissection. The purpose of this study was to determine the minimum lymph node yield (LNY) of an elective level I-III neck dissection required to reliably capture any positive nodes present in these nodal basins. STUDY DESIGN: Retrospective single-institution analysis. METHODS: All patients with the diagnosis of head and neck squamous cell carcinoma who underwent elective level I-III neck dissection between 2004 and 2015 at our institution were analyzed...

BACKGROUND: Human papilloma virus (HPV) infection has been shown to play an integral role in the development and prognosis of various head and neck cancers. Generational changes in sexual behavior may have led to an increased incidence of positivity in recent years. HPV positivity in both benign and malignant lesions of the sinonasal cavities has been shown in previous studies (estimates range from 20%-30% for malignancy). We intend to investigate if HPV positivity affected survival outcomes in our patient cohort...

BACKGROUND: G protein-coupled receptor family C group 5 member A (GPRC5A), a retinoic acid-inducible gene, is a lung tumor suppressor. Previously, we showed that repression of GPRC5A expression was associated with pathologic differentiation grade of oral squamous cell carcinomas (OSCC) and overexpression of GPRC5A gene inhibited the malignant phenotype in OSCC cells, suggesting that GPRC5A also functions as a tumor suppressor in oral cancer. However, the molecular mechanisms underlying GPRC5A deficiency in head and neck squamous cell carcinoma (HNSCC) are still unclear...
