Fatality among Brazil teens and young adults among 2001 to be able to 2019: a great research Worldwide Burden of Disease examine.
The investigations revealed multiple external (on the whole body) and internal injuries. According to the statements of those who called the ambulance, the injuries occurred because of falling on the stairs and were considered by the family as being superficial, without requiring medical care. The forensic autopsy, through the external, internal and histopathological examination, highlighted the specific injuries that led to the death, thereby contributing to the elucidation of the tanatogenerative mechanism, of the way the lesions were produced and to the applying the law.Internal carotid artery (ICA) anatomical variations are relatively rare occurrences during diagnostic imaging procedures. Their presence can have important prognostic consequences in the evaluation of vascular neurological diseases. It is therefore important to have a good knowledge about these variations, in order to avoid unwarranted medical interventions. We present the case of a patient harboring a right ICA fenestration in the cervical segment, misdiagnosed as a dissection on computed tomography angiography, admitted in the Department of Neurology and treated accordingly. The possible pathological and embryological origins of arterial fenestrations are discussed, and a brief review of the literature related to ICA fenestrations is presented.Among the subtypes of germ cell tumors, teratomas are the most frequent in the pediatric population and commonly occur in the sacrococcygeal region and the gonads. Less than 1% of all teratoma are found in abdominal organs including the stomach, liver, and kidney. Gastric teratomas are very rare tumors predominantly found in infants. Moreover, an immature gastric teratoma is exceptionally rare. Here, we present a case of immature gastric teratoma with spontaneous rupture in a newborn who was preoperatively diagnosed with neuroblastoma. On the first day after birth, the neonate presented with progressive abdominal distension accompanying respiratory distress. A firm mass was detected during a physical examination of the abdomen. An emergency exploratory laparotomy revealed hemoperitoneum resulting from a rupture of the tumor located in the posterior wall of the gastric antrum. Complete resection of the tumor and gastroduodenostomy were performed. The pathology evaluation revealed a grade 3 immature gastric teratoma with no malignant components. The patient was treated with adjuvant chemotherapy to prevent recurrence, since the tumor was ruptured in the abdominal cavity and the level of alpha-fetoprotein was decreased but still remained high above the normal range after surgery. In conclusion, physicians should be aware of the existence of gastric teratoma as the differential diagnosis of a huge abdominal mass in infants, especially neonates. Complete surgical removal of the tumor and long-term follow-up has been adopted as the standard management for immature gastric teratoma, although there has been controversy with adjuvant chemotherapy.Giant cell tumor (GCT) is a locally aggressive tumor but with benignity features, representing approximately 18% of non-malignant bone tumors in European countries, with slight female predominance. Malignancy in GCT is rare, about less then 2% of cases and is more common at older ages. Is known that usually occurs at the epiphyses of long bones, but extremely rare may have another location, such as the pelvic bone. An atypical location - the posterior iliac bone, found at a 34-year-old male -, is the case report we studied and described. Starting from the patient's complains, like a mass in the left buttock region described as "recently appeared", firm, not-mobile, with no distinctive borders and no tenderness at palpation, and a recent history trauma, multiple investigations have been performed, which have highlighted an osteolytic lesion, close to the sacroiliac joint, only with infiltration of the gluteal, iliac and paravertebral muscles. The treatment of choice was hemipelvectomy, with wide tumoral resection, and selective embolization of the nutrient vessels 24 hours prior to the surgical procedure. At two years postoperative, we found a good functional result and the computed tomography (CT) scan revealed no signs of recurrence.Male breast lymphoma is a rare extranodal lymphoma occupying the mammary gland, and it could be either primary or secondary. A 78-year-old man presented an enlargement of the right breast. He had no medical history of interest. On physical examination, a unilateral, painless breast lump was found, with no skin changes or nipple discharge. There was no palpable lymphadenopathy. Routine laboratory tests revealed leukocytosis and lymphocytosis. Excisional biopsy of the breast lesion revealed mammary tissue infiltration by chronic lymphocytic leukemia (CLL) with plasmacytoid features and immunoglobulin G∕kappa monotypic expression. To our knowledge, this is the first report of male breast involvement by CLL. Considering important the collection of clinicopathological data of all reported male breast lymphoma cases, a literature review is presented.Squamous metaplasia occurring within a colorectal polyp is a rare finding, having a reported incidence of approximately 0.44%. OG-L002 solubility dmso The origin of the squamous cells in this type of setting is uncertain (mechanical irritation and chronic inflammation are potential predisposing factors). It has been implied that the significance of squamous metaplasia in colorectal adenomas is that of a preneoplastic lesion for squamous cell and adenosquamous carcinoma, however the evidence to support this statement is scarce. We present a case of a large tubulovillous adenoma located in the sigmoid, with low-grade dysplasia and multiple foci of p16-positive immunoexpression squamous metaplasia in a 54-year-old Caucasian male, presenting with rectal bleeding.Leiomyosarcoma (LMS) of the inferior vena cava (IVC) is a rare malignant tumor, accounting for 2% of all LMSs. Less than 400 cases have been reported in literature. Computed tomography (CT) is the most accurate imaging method in assessing the location of the tumor within the IVC and magnetic resonance imaging (MRI) accurately identifies its extent and the potential for surgical resection. We present the case of a patient with inferior vena cava leiomyosarcoma (IVCL), for whom the pathological diagnosis was different from the initially expected one, the tumor appearance on pre-operative imaging mimicking renal cell carcinoma. The intraoperative difficulty of approaching renal hilum and IVC was a factor suggesting the vascular origin of the tumor, which was confirmed at pathological analysis. The extensive defect in the IVC after tumor excision led to the decision of complete transverse suturing of IVC, as significant collateral venous circulation was already present. Because IVCL is a rare disease, there is scarce data regarding the prognosis and treatment options.
