BACKGROUND: Renal cell carcinomas represent 85% of malignant renal tumors. Typically, the tumor remains asymptomatic a long time before the appearance of urologic clinical signs. In some cases, metastasis can precede the manifestations of the primary tumor. Different sites are potential metastatic localizations for renal tumors, including skull metastases who represent a very rare location. CASE DESCRIPTION: We report the case of a 65-year-old man presented after the appearance of a skull mass...

Aneurysmal bone cysts (ABCs) are expansile cystic lesions that can affect any bone of the body. Whilst these lesions are histologically benign, the lesions are locally aggressive and can affect the integrity of the affected bone as well as surrounding structures. ABCs arising in the head and neck region, particularly the paranasal sinuses are rare and they are limited to case reports in the literature. Due to the proximity of critical anatomical structures and the visual apparatus, the potential complications can be devastating...

The goal of this study was to determine whether frontal sinus hypoplasia coexists with maxillary sinus hypoplasia. Analyzing paranasal CT scans retrospectively, we included 86 patients who had a hypoplastic maxillary sinus at least on one side and 80 patients with bilateral normal maxillary sinuses (control group). We classified hypoplastic maxillary sinuses using the classification system previously defined by Bolger et al. (Otolaryngol Head Neck Surg 103(5):759-765, 1990). We classified the frontal sinuses as aplastic, hypoplastic, medium-sized, and hyperplastic; as previously defined by Guerram et al...

This paper presents an extremely rare case of synovial sarcoma arising from the maxillary sinus, which resulted in a clinically complete response to chemotherapy. Synovial sarcoma is a rare soft tissue malignant tumor, most commonly affecting the extremities. While ~10% occur in the head and neck region, synovial sarcoma of the sinonasal tract is extremely rare, with only 11 cases having been reported previously. As with other sarcomas, the standard treatment is complete resection while allowing for a safe margin, but this is often difficult in the head and neck area due to the complicated anatomy there...

BACKGROUND: Planar lymphoscintigraphy (PL) has a lower detection rate of sentinel lymph nodes (SLNs) in head and neck melanoma compared with other sites. We assessed situations when single-photon emission computed tomography/computed tomography (SPECT/CT) identified nodes not seen by PL. We also evaluated the impact of SPECT/CT on surgical approach and oncologic outcomes. METHODS: Patients who underwent SLN biopsy (SLNB) for head and neck melanoma with PL and SPECT/CT between November 2011 and December 2016 were included...

We would like to draw to the attention of head and neck surgeons the following disease that can present first to head and neck specialists with either a head and neck lump or following an incidental finding on radiological imaging. Familial Adenomatous Polyposis (FAP) is a hereditary disease caused by a mutation in the APC gene on chromosome 5, which is inherited in an autosomal dominant fashion with complete penetrance but variable expression(1). However in approximately 25% of cases it arises from a de novo mutation of the APC gene(1)...

Neuroendocrine carcinomas of the head and neck are rare and are classified as well differentiated, moderately differentiated, and poorly differentiated carcinomas with the latter category being subdivided into small cell and large cell neuroendocrine carcinoma (LCNEC). While most carcinomas in the nasopharynx are associated with Epstein-Barr virus (EBV), there has been only one previous report demonstrating a link between EBV and LCNEC of the nasopharynx. In this report we describe a second case of EBV-positive LCNEC arising in the nasopharynx with bilateral cervical metastases...
