In this paper, our main objective was to emphasize the competency of extended deltopectoral exposure, enforced with the supraspinatus and subscapularis detachment, to gain access to the entire head. The second important point in this paper was to underline the importance of the knowledge that is necessary for interpreting classic radiologic signs of posterior fracture-dislocation of the shoulder. A 47-year-old woman fell down directly onto her shoulder while she was skiing. She was diagnosed with posterior shoulder dislocation, associated with fracture of the head (head splitting) and humeral neck fracture, with the aid of plain radiographs and computed tomographic results...

Extraskeletal myxoid chondrosarcoma (ESMC) is an extremely rare variant of chondrosarcoma accounting for less than 10% cases. It affects mainly the soft tissues of the proximal end of long bones. Its incidence in the head and neck region is less than 5%. This case presented in the nasopharynx, an exceedingly unusual site for ESMC in a 60-year-old female with left-sided nasal obstruction and occasional epistaxis of one-year duration. Biopsy from the nasopharyngeal mass was suggestive of low-grade chondrosarcoma...

Poorly differentiated chordomas are rare musculoskeletal tumors. Case 1. A 42-year-old lady presented with quadriparesis of 2 months' duration. Radiologic imaging disclosed a soft tissue mass in her left prevertebral- and paravertebral cervical region. Case 2. A 4-year-old male child presented with neck pain and restricted head movements of 1-year duration. Radiologic imaging revealed a contrast enhancing, paraspinal soft tissue mass in his cervical region. Microscopic examination in both the cases revealed a cellular malignant tumor composed of moderate to markedly pleomorphic cells with interspersed mitotic figures, along with focal myxoid change and necrosis...

Distant metastasis in advanced breast cancer is not uncommon; however, spread to the paranasal sinuses is extremely rare. We present a case of a woman who presented to our ophthalmology colleagues with worsening unilateral proptosis secondary to a tumour mass within her ethmoid sinuses. Biopsy of the ethmoid tumour showed adenocarcinoma of unknown origin. Whole-body positron emission computed tomography demonstrated a breast primary lesion. The patient was treated with palliative chemotherapy, and the patient remains well at this point...

Non-Hodgkin's lymphoma (NHL) is a lymphatic system tumor originating from either B or T lymphocytes and shows a high malignant potential. In HIV-seropositive patients, NHL of head and neck is mainly found in Waldeyer's ring, oral mucosa, salivary glands, paranasal sinuses, and laryngeal tissue. Primary NHL rarely affects the bone. When the lesion affects the bones of the jaws, it is rare in the mandible when compared to the maxilla. In the reported cases, only 0.6% are found in the mandible. NHL of the mandible can be difficult to diagnose, and so the prime aim of the present case report is to establish appropriate diagnosis of one of such kinds...

RATIONALE: Head and Neck Solitary fibrous tumors (SFT) are very rare. They could be misdiagnosed as hemangiopericytomas (HPC). PATIENT CONCERNS: We report a 60 y o lady presenting with sinonasal mass, causing recurrent profuse bleeding. DIAGNOSES: Hemangioperocytomas versus SFT were among the differentials, according to Radiological studies. Upon Biopsy, the diagnosis of SFT has been adopted. INTERVENTIONS: Salvage pre-operative embolization resulted in bleeding control, bridging the patient to surgery...

BACKGROUND: As far as our literature searches showed us, morphological characteristics of cranium such as sutures, sutural bones and fontanelles had been examined from the skulls in the museums and dry specimens until now. As a modern method, 3D virtual remodeling of cranial bones by using MDCT-CTA can display in vivo morphological characteristics. In our study, we aimed to determine the presence and incidence of these morphological characteristics that can be clinically significant in our population, by using radiologic methods...

Osteosarcoma (OS) is a malignant bone tumor and it is very rare in head and neck region. If it arises in this area, most common localizations of this tumor are mandible and maxilla and ethmoid sinus is very rare site for this malignancy. A 43-year-old female admitted to our clinic with the complaint of pain in the right half of the face and headache persisting for 2 months. According to the clinical symptoms and imaging studies, sinonasal ossifying fibroma was suspected. For this reason, patient was operated endoscopically and histopathological examination revealed that osteoid matrix producing atypical osteoblastic cells so these findings identified osteoblastic variant OS...

Objectives: Management of neck metastases in terms of diagnosis and treatment has always been a controversial issue in patients of head and neck malignancy. The main area of debate in case of diagnosis lies with the fact that whether we should rely on ultrasound, as a diagnostic modality for diagnosing micrometastases in the neck in head and neck malignancy patients? The second controversial issue is the management of N0 neck, whether to be radical or conservative? Materials and Methods: This study was conducted on 70 diagnosed patients of head and neck carcinoma who were planned for resection of the primary...

A granular cell tumor (GCT), is a rare soft tissue tumor which may occur throughout the body, usually in the head and neck, skin or subcutaneous tissues of the trunk and upper extremities, and female genital region. A total of 5-8% of all cases of GCTs occur in the breast. GCT of the breast may mimic breast cancer both clinically and radiologically. GCTs are usually benign and solitary; however, approximately 2% occur as malignant tumors. Benign GCTs are treated with wide local excision and are associated with a good prognosis...

BACKGROUND: Radiomics is a promising methodology for quantitative analysis and description of radiological images using advanced mathematics and statistics. Tumor delineation, which is still often done manually, is an essential step in radiomics, however, inter-observer variability is a well-known uncertainty in radiation oncology. This study investigated the impact of inter-observer variability (IOV) in manual tumor delineation on the reliability of radiomic features (RF). METHODS: Three different tumor types (head and neck squamous cell carcinoma (HNSCC), malignant pleural mesothelioma (MPM) and non-small cell lung cancer (NSCLC)) were included...
