INTRODUCTION: Heterotopic gastric grands (HGGs) are gastric grands that are observed in the submucosa and are considered to be paracancerous lesions or precursors of gastric cancer (GC). Granular cell tumors (GCTs) are benign neural origin tumors. Gastrointestinal GCTs are rare and gastric GCTs are seldom seen. We report the case of a patient who was diagnosed with early GC with diffuse HGGs affecting the whole stomach and two GCTs mimicking advanced GC. PRESENTATION OF CASE: The patient is a 71-year-old male with epigastric discomfort...

An osteochondroma, when reported in the maxillofacial region, is a benign neoplasm that involves the skull base, maxillary sinus, zygomatic arch, or mandible. Most commonly, the osteochondroma occurs in the coronoid process and the condyle. One rare subtype of osteochondroma reported in the literature, termed Jacob disease, arises from the coronoid process and interferes with the zygomatic arch. This report describes a unique case of an isolated osteochondroma arising from the zygomatic arch and interfering with the coronoid process, which was treated through surgical excision by an intraoral approach...

BACKGROUND: The malignancy risk of thyroid nodules differs according to Bethesda category, ultrasound features, and nodule size. METHODS: In 2725 thyroid nodules that underwent ultrasound-guided fine-needle aspiration, frequencies and malignancy rates of Bethesda categories were compared according to size and ultrasound assessment. RESULTS: When comparing the ultrasound suspicious nodules ≤10 mm and >10 mm, the frequency of the benign cytology was statistically higher in the >10 mm group, whereas the nondiagnostic and suspicious for malignancy cytology were higher in the ≤10 mm group...

Image-guided ablation of thyroid disease is increasingly being commonly reported. Techniques including ethanol injection and thermal ablation using radio-frequency, laser, and microwave devices have been described. Minimally invasive approaches to the management of benign cystic, solid, and functional thyroid nodules as well as both primary and recurrent thyroid malignancy have been reported. The purpose of this article is to review the current evidence relating to image-guided ablation of thyroid disease with a focus on clinical outcomes and complication rates for patients treated with this minimally invasive approach...

Heartwood extract from white mulberry (Morus alba L.) (Rosales: Moraceae) were investigated for antitermitic activity against Reticulitermes flavipes (Kollar) (Blattodea: Rhinotermitidae) in laboratory experiments. An ethanol:toluene (2:1) solvent system was used to remove extract from heartwood shavings. A concentration-dependent feeding response and mortality were observed for termites exposed to a concentration series range of 1.25 to 10 mg/ml of extract based on their dry weight. Results showed that maximum termite mortality occurred at 10 mg/ml...

OBJECTIVES: Pancreatic cancer (PC), a common cause of cancer death, is rarely diagnosed at an early stage. Early detection of PC may improve outcomes in affected patients. This study evaluated the utility of screening of high-risk individuals (HRIs) using an endoscopic ultrasound (EUS)-only approach to detect early malignant changes. METHODS: A prospective PC screening program for HRIs was opened in 2007. Fifty-eight patients have enrolled to date. Patients with normal EUS examinations underwent repeat EUS annually for 5 years...

Lipoblastoma is a rare, benign tumor usually occurring in childhood. It is essentially localized in the extremities and trunk, with few cases reported in the neck. We report the case of a 2-year-old girl with a rapidly enlarging, painless neck mass. Magnetic resonance imaging (MRI) revealed a 3-cm mass in the right submandibular region. Review of literature, diagnostic methods, and genetics of lipomatous tumors are discussed. Complete surgical excision via a lateral cervical approach demonstrated a white soft tissue with an adherent ganglion...

An inflammatory fibroid polyp (IFP) is a solitary rare benign neoplasm of the gastrointestinal tract, frequently located in the gastric antrum. IFPs account for about 0.1% of all gastric polyps. We report a case of a giant gastric inflammatory polyp of 2.5 cm × 7 cm that determines a gastric outlet obstruction called "ball valve syndrome" mimicking a gastrointestinal stromal tumor (GIST) and a gastric lymphoma, with an intestinal obstruction of high origin. Therefore, due to acute presentation we have decided to submit the patient to a subtotal gastrectomy...

Although controlled studies have demonstrated the benefits of a minimally invasive approach for pulmonary lobectomy over thoracotomy, reports have also documented that significant complications can occur during thoracoscopic lobectomy and sometimes require planned or emergent conversion to open surgery. Several authors have identified and reported causes and implications of intraoperative conversion to thoracotomy using different types of classification. The aim of this single centre retrospective review is to evaluate how the reasons for conversion change with increased experience, dividing patients who were converted to thoracotomy during video-assisted thoracic surgery (VATS) lobectomy, between 2011 and 2017, in two groups: those treated during learning curve (LC group) and those treated after learning curve (ALC group)...

Intracranial tumors (ICTs) attract numerous scientific teams and tremendous financial resources worldwide. These lesions of the central nervous system (CNS) can be both benign and malignant in biological behavior as well as local or metastatic in origin. We compared data from two studies on primary and metastatic ICTs from Brazil and Bulgaria, based on histopathologically confirmed ICTs from tertiary health centers. Primary ICTs significantly outweigh the frequency of metastatic ICTs. Primary ICTs represent 86...

Prostatic blue nevus is a rare benign pathologic diagnosis most commonly diagnosed incidentally on many different types of prostate specimens. Blue nevus is the deposition of stromal melanin characterized by spindle cells within the fibromuscular stroma which stains positive for melanin-specific stains Fontana-Masson and S100 and stains negative for CD68, HMB45, and iron stains. We report the case of a multifocal and bilateral blue nevus in a 52-year-old Hispanic male who presented with an elevated prostate-specific antigen of 4...

Ameloblastoma is locally aggressive benign odontogenic tumour with increased risk of recurrence rate. The choice of treatment depends on the histologic subtype. Radical therapy is the recommended modality for solid ameloblastomas. The possibilities of recurrence even after enbloc resection are still high. The author presents two case reports of recurrent ameloblastomas postradical resection. First case describes the recurrence of ameloblastoma in the bone graft which was used for reconstruction, and the second case depicts recurrence in the infratemporal fossa...

Objective: The objective is to present a clinical case of a 38-year-old male with a maxillary unicystic ameloblastoma treated by means of tumor block resection followed by chin-harvested graft placement in order to place two dental implants for esthetic and functional rehabilitation. Methods: Ameloblastoma is a benign odontogenic tumor characterized by local aggression and a high rate of recurrence; the latter partly depends on how it is treated. Complete resection of the tumor, which usually prevents recurrence, produces bone defects of varying size that must be reconstructed later on...

Solitary fibrous tumor/hemangiopericytomas (SFT/HPC) are soft tissue tumors that can arising from the abomen, pleura, head and neck, or extremities. We report an unusual case of recurrent hemangiopericytoma in a 67-year-old female presenting with a painless and palpable mass within her right posterior neck. Eight years after initial resection of the mass, a follow-up MRI showed multiple enlarging calvarial lesions. A whole body FDG-PET/CT revealed not only hypermetabolic calvarial lesions but also numerous hypermetabolic axillary node and osseous metastases...

Meningiomas are benign tumors origin from central nervous system. They usually involve cephalic, paravertebral soft tissues, skin and in rare cases in the ear, temporal bone, mandible, foot, lung, and mediastinum. In this case, we report an unusual case of meningioma which placed in the fourth ventricle. A 14-year-old man with seizure and headache referred to our ward. The magnetic resonance imaging reported bilateral acoustic neuroma and fourth ventricle meningioma. The patient was scheduled for total tumor resection and the histopathology revealed psammomatous type of meningioma...
