A Sizeable Solitary Pedunculated Peripheral Osteoma of the Hard Palate: A Case Report.

ABSTRACT: Osteomas are benign, slow growing, usually sessile osteogenic tumors of unknown etiology. They arise from proliferation of either cancellous or compact bone. They can be central, peripheral or extra-skeletal based on their origin from endosteum, periosteum or extra-skeletal soft tissue respectively. They are commonly found in the skull and facial bones, the most common site in the maxillofacial region being paranasal sinuses. Among the jaw bones the most common site is the mandible. The hard palate is a rare site for such osteomas with a very few cases reported in literature. We report a case of large pedunculated peripheral osteoma of the hard palate in a 38 year old male. The tumor was excised with no recurrence after 3 years followup.

Solitary Peripheral Osteoma of the Hard Palate Case report and literature review.

Project description:Osteomas are benign slow-growing osteogenic lesions of unknown aetiology which can be central, peripheral or extraskeletal. Peripheral osteomas of the maxilla are very uncommon. We report a 72-year-old female patient who presented to the Department of Oral & Maxillofacial Surgery, Dental School of Athens, Athens, Greece, in 2015 with swelling of the palate following a tooth extraction. Clinical and radiographical features were indicative of a solitary peripheral osteoma of the hard palate. An excisional biopsy and histological examination of the lesion confirmed the diagnosis. No complications occurred during the postoperative period and there was no evidence of recurrence at a one-year follow-up.

Plasmacytoid Myoepithelioma of the Hard Palate: Case Report.

Project description:Myoepitheliomas are uncommon salivary gland neoplasms consisting entirely or predominantly of cells with myoepithelial phenotype. They commonly involve the parotid gland and the minor salivary glands of the palate.A case of plasmacytoid myoepithelioma of the hard palate is described.A 55-year-old woman presented to her oral surgeon with a tumor on the hard palate. Microscopic examination showed a well-circumscribed but non-encapsulated tumor, consisting mostly of plasmacytoid cells in a loose fibrovascular stroma. Neoplastic myoepithelial cells showed immunoreactivity for S-100 protein, CK AE1/AE3 (Figure 5b), GFAP, calponin, and CD138/Syndecan-1. Total excision of the tumor under local anesthesia was performed and no recurrence was noted 14 months after treatment.Since plasmacytoid myoepithelioma is uncommon, minor salivary glands, its immunohistochemical features, management and prognosis should be further investigated.

Intra-articular osteoid osteoma at the elbow mimicking arthritis: a case report.

Project description:Osteoid osteomas are benign, typically intracortical lesions most often affecting the diaphysis of long bones. Nocturnal pain and characteristic symptoms that are relieved by administration of non-steroidal anti-inflammatory drugs (NSAIDs) are present and can help in the diagnosis of osteoid osteoma. We report a case of 18-year-old boy with an osteoid osteoma in the olecranon fossa with an atypical clinical manifestation. The initial manifestation was arthritis-like symptoms such as local heat, motion pain rather than pain at rest, and limited range-of-motion. Notably, NSAIDs were not effective at all for relieving his symptoms. Magnetic resonance imaging showed bone marrow edema around the elbow joint. The symptoms were resistant to conservative treatments, and thus, surgical resection was required. Histopathological examination showed that the lesion consisted of woven bones and osteoid tissues that anastomosed with each other. Combined with a tumor size that was less than 2 cm, clinicopathologically, the tumor was diagnosed as an osteoid osteoma. The pain was immediately relieved after the operation, and range-of-motion recovered at 2 months postoperatively. At 1 year after the surgery, the patient did not exhibit recurrence of the tumor or exacerbation of elbow pain and had a full range of elbow motion. Osteoid osteoma should be considered for the differential diagnosis of arthritis of the elbow in patients who are adolescents and young adults, which is the peak age of onset for osteoid osteoma.

Case Report: Multimodal Imaging Features of Pedunculated Liver Masses in Seven Dogs.

Project description:This study describes the multimodal imaging characteristics of pedunculated liver masses in seven dogs [Cocker Spaniel (n = 2), Maltese (n = 1), Shih-Tzu (n = 2), and Schnauzer (n = 2)]. These masses are anatomic variants of hepatic masses in which the center of the mass lies outside the liver contour. Prior to referral, only one dog had been diagnosed with a hepatic mass, four had been diagnosed with mid-abdominal masses of unknown origin, and two had been misdiagnosed with splenic head and pancreatic masses. Using radiographs, the mass locations were classified as cranioventral (n = 3), mid-abdominal (n = 2), or craniodorsal (n = 2). The gastric axis was deviated in various directions in four cases. Based on computed tomography (CT) findings, the masses were noted to originate from every liver lobe (two from the left lateral lobe) and to possess parenchymal (n = 6) or vascular (n = 1) pedicles. The histopathological results showed that three masses were benign [hepatic adenoma (n = 1) and nodular hyperplasia (n = 2)] and four were malignant [hepatocellular carcinoma (n = 3) and cholangiocarcinoma (n = 1)]. For three dogs, triple-phase CT maximum intensity projection images in the arterial phase clearly showed that the masses were connected to the hepatic artery. We propose that a pedunculated liver mass should be considered as a differential diagnosis when a mass is located in the mid-abdomen, even if it is separated from the liver and with the gastric axis deviated in various directions. We consider CT imaging to be a useful tool for diagnosis, evaluation, and surgical planning in dogs with a pedunculated liver mass.

Surgical Navigation, Augmented Reality, and 3D Printing for Hard Palate Adenoid Cystic Carcinoma En-Bloc Resection: Case Report and Literature Review.

Project description:Adenoid Cystic Carcinoma is a rare and aggressive tumor representing less than 1% of head and neck cancers. This malignancy often arises from the minor salivary glands, being the palate its most common location. Surgical en-bloc resection with clear margins is the primary treatment. However, this location presents a limited line of sight and a high risk of injuries, making the surgical procedure challenging. In this context, technologies such as intraoperative navigation can become an effective tool, reducing morbidity and improving the safety and accuracy of the procedure. Although their use is extended in fields such as neurosurgery, their application in maxillofacial surgery has not been widely evidenced. One reason is the need to rigidly fixate a navigation reference to the patient, which often entails an invasive setup. In this work, we studied three alternative and less invasive setups using optical tracking, 3D printing and augmented reality. We evaluated their precision in a patient-specific phantom, obtaining errors below 1 mm. The optimum setup was finally applied in a clinical case, where the navigation software was used to guide the tumor resection. Points were collected along the surgical margins after resection and compared with the real ones identified in the postoperative CT. Distances of less than 2 mm were obtained in 90% of the samples. Moreover, the navigation provided confidence to the surgeons, who could then undertake a less invasive and more conservative approach. The postoperative CT scans showed adequate resection margins and confirmed that the patient is free of disease after two years of follow-up.

Solitary neuroendocrine carcinoma of the heart: a case report.

Project description:Background:Cardiac tumours are of rare incidence and usually occur in the form of secondary tumours. Most metastatic tumours are melanomas, sarcomas, lung, and haematological malignancies. Neuroendocrine carcinomas (NECs) of the heart are extremely unusual. This case report demonstrates a solitary high-grade NEC of the heart with an individual therapy strategy and follow-up. Case summary:A 50-year-old gentleman presented with a 2?days history of recurrent episodes of chest pain. Echocardiography, computed tomography, and magnetic resonance imaging revealed tumorous lesions of the ventricles and aortic valve with large circular pericardial effusion. Histopathology results of the biopsy revealed a poorly differentiated small cell tumour of the neuroendocrine type. Despite further investigations with multiple imaging modalities and laboratory, no primary was found. Chemotherapy was initiated but size progression of the tumour was detected. As no other tumorous lesions were detected and resection was not possible because of the tumour complexity, decision on heart transplantation was made. However, due to the necessary immunosuppression after the heart transplantation, multiple metastasis where discovered in the course of treatment. Discussion:The presence of a NEC in the heart without evidence of any other metastasis or evidence of primary tumour in other organs is clinically unique. For this individual case, heart transplantation was the therapy of choice due to tumour progression under chemotherapy and lacking possibility of resection, as no other suspect lesion was found other than the ones found in the heart. However, the risk of exacerbation of undiscovered micrometastases under necessary immunosuppression following the heart transplantation should be considered.

Solitary Extramedullary Plasmacytoma of the Cricoid Cartilage-Case Report.

Project description:Solitary plasmacytoma (SP) is an extremely rare form of hematologic malignancy that can be classified as solitary bone plasmacytoma or solitary extramedullary plasmacytoma. Here, we report a patient who presented with progressive shortness of breath and foreign body sensation in his throat. Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) demonstrated an abnormal FDG-avid soft tissue mass arising from the larynx involving the cricoid cartilage without additional suspicious lesions. Histology revealed an abundance of plasma cells; immunohistochemistry was positive for CD138 expression and lambda chains, and negative for CD20. Comprehensive imaging studies and panendoscopy of the ENT tract confirmed solitary disease involvement. Following additional systemic work-up, a diagnosis of extramedullary plasmacytoma was rendered. The patient underwent definitive radiotherapy using intensity-modulated radiation therapy (total dose of 46?Gy, divided in 23 fractions of 200?cGy). Serial PET/CT showed the stepwise resolution of abnormal FDG uptake and resolution of the cricoid cartilage lesion. With 22?months of follow-up, the patient remains free of disease. We describe the rare case of SP presenting as a FDG-avid hypermetabolic soft tissue mass in the cricoid cartilage, which should be considered in the differential diagnosis of laryngeal tumors. Of note, SP is radiosensitive; favorable outcome can be expected once treated with doses of 40-50?Gy. FDG PET/CT is helpful in diagnosis and response assessment for this disease.
