Project description:The COVID-19 outbreak has become a pandemic that is threatening global health. The typical clinical manifestations were fever, cough, dyspnea, and myalgia or fatigue. Digestive symptoms such as nausea, vomiting, diarrhea, abdominal pain usually accompany respiratory symptoms. However gastrointestinal bleeding as the first symptom is not reported. Here we reported a case of COVID-19 with gastrointestinal bleeding as the initial symptom to the emergency department with a real-time reverse transcriptase polymerase chain reaction test positive, and normal thorax tomography. The case demonstrate that; clinicians should be alerted to patients about COVID-19 when referring to atypical symptoms and every patient undergoing endoscopy should be considered potentially infected or can infect others.

Parotid Ewing's sarcoma: Extra-skeletal uncommon condition.

Project description:IntroductionThe parotid gland is a very rare location of Ewing's sarcoma. Its clinical and radiological manifestations are atypical. Its management is based on a multidisciplinary approach to improve prognosis and survival.DiscussionThe diagnosis of parotid Ewing's sarcoma is determined by a combination of genetic and histological criteria. Its local aggressiveness and high metastatic potential require prompt and appropriate management. Many prognostic features affect its management, the most important is the TNM staging.ConclusionLimited cases of parotid Ewing's sarcoma have been published in the literature. This small number of reported cases is the only way to study its characteristics.

An uncommon presentation of giant cell tumor.

Project description:Giant Cell Tumors commonly occur at the ends of long bones. However in rare cases, they can occur in the bones of the hands and feet. Tumors in these locations occur in younger patients; in addition, these tumors are more commonly multifocal and are associated with a higher risk for local recurrence than tumors at the ends of long bones. Since lesions in the small bones may be multifocal, a patient with a giant cell tumor of the small bones should undergo a skeletal survey to exclude similar lesions elsewhere. Primary surgical treatment ranges from curettage or excision with or without bone grafting to amputation. The success of surgical treatment depends on the completeness with which the tumor was removed. We are presenting a case report of a 34 year old female, who presented with a swelling in the right hand, following trauma. X-ray of the hand showed an osteolytic expansile lesion at the base of the 1(st) metacarpal bone. The lesion was initially curetted and then treated by local resection with bone grafting. Histological examination revealed a typical benign giant cell tumor composed of closely packed stromal cells with a variable admixture of giant cells. Follow up at the end of one year did not reveal any recurrence of the tumor.

Uncommon Presentation of an Unusual Foreign Body.

Project description:Esophageal foreign bodies (FBs) are common and can be the serious cause of morbidity and mortality in children. One-third of FBs, retained in the gastrointestinal tract, are found in the esophagus. Their management depends on the anatomical location, shape, size, and the duration of impaction. In children, unwitnessed esophageal FBs can present with respiratory symptoms such as stridor. Therefore, a high index of suspicion is generally required to avoid significant morbidity and mortality. We are reporting an unusual FB with unusual symptoms in a 2-year-old female child.

Retroperitoneal extra-adrenal non-Hodgkin lymphoma: An uncommon presentation.

Project description:Primary retroperitoneal non Hodgkin lymphoma is extremely rare, its diagnosis is often difficult and it may requires a time consuming and a costly diagnostic workup. We report the case of a 46-year-old patient complaining of abdominal fullness and dorsal pain, who was diagnosed with an extra-nodal non-Hodgkin lymphoma presenting as a unique and large retroperitoneal mass. The suggested diagnosis was a malignant retroperitoneal tumor and the patient underwent an excision of the tumor throw a lombotomy followed by an R-CHOP chemotherapy regimen with good outcome.

Right atrial myxoma: Unusual location; uncommon association.

Project description:We are presenting a case of the right atrial myxoma found in a case of rheumatic heart disease. During transthoracic echocardiography for the evaluation of a suspected rheumatic valvular heart disease, a diagnosis of severe mitral stenosis with severe mitral regurgitation with the right atrial thrombus was made. On transesophageal echocardiography, a pedunculated mass in the right atrium was confirmed. In the course of surgery, it was found that there is a tumor originating from the right atrial appendage (RAA) which was confused with clot on echocardiography. Rheumatic heart disease and myxomas have different etiopathogenesis, and this coexistence has not been reported. Further, right atrial myxoma arising out of RAA is also being reported for the first time.
