Review
A systematic review of the literature from 1993 to 2011 was undertaken examining frequency data of the most common odontogenic cysts and tumors. Seven inclusion criteria were met for the paper to be incorporated. In the preliminary search 5231 papers were identified, of these 26 papers met the inclusion criteria. There were 18 297 odontogenic cysts reported. Of these there were 9982 (54.6%) radicular cysts, 3772 (20.6%) dentigerous cysts and 2145 (11.7%) keratocystic odontogenic tumors. With the reclassification of keratocystic odontogenic tumor in 2005 as an odontogenic tumor, there were 8129 odontogenic tumors reported with 3001 (36.9%) ameloblastomas, 1163 (14.3%) keratocystic odontogenic tumors, 533 (6.5%) odontogenic myxomas, 337 (4.1%) adenomatoid odontogenic tumors and 127 (1.6%) ameloblastic fibromas. This systematic review found that odontogenic cysts are 2.25 times more frequent than odontogenic tumors. The most frequent odontogenic cyst and tumor were the radicular cyst and ameloblastoma respectively.

BACKGROUND
Odontogenic myxoma (OM) is a rare neoplasm, which originates from odontogenic ectomesenchyme. There is no study in the literature that analyses the best standards for OM diagnosis and how the treatment modalities may influence the recurrence rates.
OBJECTIVE
To evaluate the best standards for odontogenic myxoma (OM) diagnosis and treatment, and how these may influence the recurrence rates.
STUDY DESIGN
Two independent researchers performed a systematic review in many databases. Fifty-two eligible studies were included for qualitative analysis. Bias analysis was conducted according to Oxford Centre for Evidence-Based Medicine.
RESULTS
A total of 1363 OM cases were reported on, and female gender with average age of 27 years is the most common patient profile. Conventional microscopic findings were observed in 93.43% of the reported cases. In 57.49% of the cases, multilocular radiographic appearance was present, followed by unilocular appearance (32.87%). Posterior mandible was the site with the major prevalence, while surgical resection was the most common treatment modality, followed by enucleation. Recurrence rates for both treatment modalities were approximately close (13.04% and 25.0%, respectively).
CONCLUSION
The correct diagnosis of OM relies on the association of clinical, radiographic and microscopic findings. About imaging examinations, panoramic radiography and computed tomography are sufficient for the evaluation of OM. Recurrence rates were closely among the two most used surgery treatments. So according to some clinical-radiological aspects, conservative surgery may be preferred than aggressive surgery modalities.

Review
Conjunctival myxoma is an uncommon benign tumor that may develop as a localized disease or as part of the Carney complex, in which case it can cause significant morbidity and mortality. Conjunctival myxomas can mimic other pure or mixed tumors and are often overlooked in clinical practice. Histopathological studies are essential for diagnosis; however, controversy regarding their pathological and immunohistochemical features makes the diagnostic process more difficult. Because of the importance of correctly classifying these conjunctival tumors, as well as recognizing when a systematic screening is required owing to the possible association with life-threatening diseases, we comprehensively evaluate the literature on this rare entity based on a systematic approach.

Review
OBJECTIVE
To determine common etiologies, presentations, management strategies and outcomes in patients with tumor embolism causing acute arterial occlusion.
STUDY DESIGN
This is a systematic review of published case reports on tumor embolism.
SEARCH STRATEGY
All published cases of tumor embolism in the MEDLINE and EMBASE databases were reviewed. The search terminologies were (Tumor Embolism), (Ischemia), (Occlusion) and (Infarction).
INCLUSION AND EXCLUSION CRITERIA
All published reports of tumor embolism were included. Studies regarding venous thromboembolism and cancer-associated thromboembolism without tumor embolization were excluded. The cases included numbered 42.
OUTCOME MEASURES
These included the frequencies of different primary tumor types, clinical presentations, anatomical sites of embolization, types of intervention and outcomes including number of deaths and successful discharges.
RESULTS
Lung cancer and Atrial Myxoma each accounted for 14 out of 42 cases (33%). There were 11 cases (26.9%) of stroke and 9 cases (21.4%) of myocardial infarction and limb ischemia. Femoral thrombo-embolectomy was performed in all 9 cases of limb ischemia and Primary coronary intervention was performed in 7 out of 9 (77.8%) cases of myocardial infarction. There were 14 inpatient deaths (33.3%) and 19 patients were successfully discharged (45.2%).
CONCLUSION
Lung cancer and atrial myxoma were the most common sources for tumor embolism. Acute stroke was the most common presentation. This is treated with antiplatelets or anticoagulation as well as chemotherapy and resection of primary tumor. Early revascularisation can prevent severe complications such as death, paralysis, heart failure and limb loss in selected cases of tumor embolism.
KEY MESSAGE
Histopathological examination of embolic tissue can demonstrate tumor tissue and alert the clinician to a cancer elsewhere. This is most likely to be lung cancer or atrial myxoma. Early revascularisation in selected cases of acute tumor embolism can prevent severe complications and these patients should not be automatically palliated due to their underlying neoplasm.

Review
: The association between cerebral aneurysms and left atrial myxoma is known but rare. We described its pathogenesis, clinical presentation, diagnostic findings and treatment using a systemic review of the literature. : MEDLINE via PubMed was searched for articles published until August 2022 using the keywords "atrial myxoma", "cardiac myxoma" and "cerebral aneurysm". : In this review, 55 patients with multiple myxomas aneurysms were analyzed, and 65% were women. The average age when aneurysms were diagnosed was 42.5 ± 15.81; most patients were less than 60 years old (86%). Aneurysms could be found before the diagnosis, at the same time as cardiac myxoma, or even 25 years after resection of the atrial mass. In our review, the mean time to diagnoses was 4.5 years. Our review estimates that the most common symptoms were vascular incidents (25%) and seizures (14.3%). In 15 cases, variable headaches were reported. Regarding management strategies, 57% cases were managed conservatively as the primary choice. : Although cerebral aneurysms caused by atrial myxoma are rare, the long-term consequences can be serious and patients should be monitored.

BACKGROUND
Stroke presentation secondary to a cardiac myxoma thromboembolism is rare in the pediatric population. Because of such rarity, the reported cases in the literature are primarily case reports. Additionally, general pediatric stroke management lacks evidence-based guidelines because of its low incidence and lack of clinical trials. In pediatric strokes identified from a cardiac myxoma, the incidence favors boys with the classical presentation of unilateral weakness and aphasia. We present a pediatric patient who presented with strokelike symptoms secondary to an intracranial embolus from a previously undiagnosed cardiac myxoma.
METHODS
We performed a systematic review by searching PubMed, Google Scholar, Web of Science, and Embase databases for cases of pediatric myxoma causing stroke (n = 2431) and identified 19 reported uses of surgical management in treating pediatric patients who present with stroke symptoms secondary to a cardiac myxoma thromboembolism.
RESULTS
The most common imaging modality was magnetic resonance imaging in 42% of cases, computed tomography in 36.8%, followed by computed tomography angiography in 31.6% of cases. Of these 19 children treated with procedures, 36.8% of pediatric patients aged between 4 and 14 years underwent neurosurgery (n = 7).
CONCLUSIONS
We describe an urgent mechanical thrombectomy and share preoperative and postoperative images and pathology slides confirming a stroke from myxoma origin. We provide added insight in the safe use of mechanical thrombectomy as treatment for pediatric strokes secondary to a thromboembolism.

Meta-Analysis
OBJECTIVES
Cardiac tumors and their associated outcomes are poorly characterized. This study sought to comprehensively assess the epidemiology and natural history of primary and secondary malignant cardiac tumors (PMCT and SMCT), a well as establish predictors of mortality.
METHODS
A comprehensive literature review was performed to identify articles reporting on PMCTs and SMCTs. The prevalence of important cardiac tumor (CT) subtypes was evaluated and further stratified based on the continental region. Outcomes of interest included short- and long-term mortality and utilization of heart transplantation (HTX). A random effect model was adopted, and a meta-regression was performed to determine predictors of the prevalence of CTs as well as predictors of operative mortality.
RESULTS
Of the 1,226 retrieved articles, 74 were included in our study (n = 8,849 patients). The mean follow-up was 2.27 years, mean age was 42.9 years, and 55% of the patients were females. There was a total number of 7,484 benign primary cardiac tumors (PCTs) (5,140 were myxoma), 862 (9.7%) malignant PCTs, and 355 secondary cardiac tumors. The prevalence of PMCTs among PCTs was 10.83% [95%CI = 09.11; 12.83%] with a trend towards being lower in South America compared to other continents (Prevalence = 5.80%). The prevalence of HTX among all patients was 2.45% [1.36; 4.38%]. The pooled short-term mortality was 5.90% [4.70; 7.39%] and the incidence of late mortality in all CTs, benign CT and PMCTs was 2.55% [1.76; 3.72%], 0.79% [0.46; 1.37%] and 14.77% [9.32; 23.40%], respectively. On meta-regression, the annual volume of cardiac tumor cases per center was the only predictor of lower early mortality (Beta = -0.14 ± 0.03, P < 0.0001).
CONCLUSIONS
PMCTs represent the minority of PCT (~10%) and have a higher prevalence in Europe and North America. Survival is higher in benign pathology and is significantly improved by treatment in specialized high-volume centers. Approximately 2% of patients with CTs undergo heart transplantation.

Review
OBJECTIVES
Therapeutic assessment of odontogenic myxoma (OM) is poorly standardized. Unidimensional size criteria have shown to be unreliable in therapeutic decision-making. We evaluate the size distribution of OM and scan for associated clinicoradiological signs of aggressiveness. Additionally, we evaluate three-dimensional size delineation of OM aiming to improve future therapeutic assessment of this destructive neoplasm.
METHODS
Primarily, we reviewed the database "PubMed" for data concerning the size of OMs as radiologically determined. Afterwards, the impact of age, sex, locularity and location on the size was investigated by χ² test, Student's t-test and regression analysis. Furthermore, we statistically evaluated the impact of size on the occurrence of clinicoradiological signs of aggressiveness. Secondly, we approximated the volume of five unpublished cases of OM by semi-automatic image segmentation of cone-beam CT images.
RESULTS
Multilocular OMs were significantly larger than unilocular ones (p < 0.002). Age (0.042) and multilocularity (<0.002) significantly impacted size. Size was significantly associated with cortical perforation (0.032) and multilocularity (<0.002), further regression analysis revealed tooth resorption (0.019), cortical perforation (0.005) and multilocularity (<0.002) as significant predictors of size. Employing the volume as a mean of comparison, we found that the biggest OM (38.42 ml; multilocular) was 124 times larger than the smallest (0.31 ml; unilocular). However, using the maximum diameter (cm) as a surrogate for size, the biggest lesion (6.3) was only 5.25 times larger than the smallest (1.2).
CONCLUSIONS
Locularity and volumetric size characterization might help in therapeutic decision-making and could help to improve our understanding of OM.

Review
BACKGROUND
Cardiac myxoma is the most common type of primary cardiac tumor, with the majority located in the atrial wall. The tumor is attached to valvular structures in a few cases, of which the pulmonary valve is the least affected. Pulmonary valve myxoma may have different clinical manifestations from the more common cardiac myxomas because of its vital position. A misdiagnosis of these types of cardiac myxoma may be detrimental to the care and well-being of patients. Therefore, this systematic review aims to define the clinical characteristics of pulmonary valve myxoma and how this differs from a more common cardiac myxoma.
METHODS
Employed literature was obtained from PubMed, ScienceDirect, Scopus, Springer, and ProQuest without a publication year limit on August 23, 2022. The keyword was "pulmonary valve myxoma." Inclusion criteria were as follows: (1) case report or series, (2) available individual patient data, and (3) myxoma that is attached to pulmonary valve structures with no evidence of metastasis. Non-English language or nonhuman subject studies were excluded. Johanna Briggs Institute checklists were used for the risk of bias assessment. Data are presented descriptively.
RESULTS
This review included 9 case reports from 2237 articles. All cases show a low risk of bias. Pulmonary valve myxoma is dominated by males (5:4), and the patient's median age is 57 years with a bimodal distribution in pediatric and geriatric populations. The clinical manifestation of pulmonary valve myxoma is often unspecified or asymptomatic. However, systolic murmur in the pulmonary valve area is heard in 67% of cases. Echocardiography remains the diagnostic modality of choice in the majority of cases. Tumor attached to the pulmonary cusps or annulus and extended to adjacent tissues in all cases. Therefore, valve replacement or adjacent tissue reconstructions are required in 77% of cases. The recurrence and mortality are considerably high, with 33% and 22% cases, respectively.
CONCLUSIONS
Pulmonary valve myxoma is more common in males with a bimodal age distribution, and its outcomes seem worse than usual cardiac myxomas. Increasing awareness of its clinical symptoms, early diagnosis, and complete myxoma resection before the presence of congestive heart failure symptoms are important in achieving excellent outcomes. A firm embolization blockade is needed to prevent myxoma recurrence.

Meta-Analysis Review
Cardiac myxoma is the most common primary cardiac tumor. However, existing literature mainly consists of single-center experiences with limited subjects. This systematic review aimed to provide data on clinical characteristics and surgical outcomes of cardiac myxoma. We performed a thorough literature search on May 23, 2023 on PubMed, ProQuest, ScienceDirect, Scopus, and Web of Science. The inclusion criteria were English full-text, observational studies, and included >20 subjects. From the search, 112 studies with a total of 8150 patients were included in the analysis. The mean age was 51 years (95 % confidence interval [95%CI] = 49.1-52.3), and the majority were females (64.3 % [95 % CI = 62.8-65.8 %]). The most common clinical manifestation was cardiovascular symptoms. Echocardiography can diagnose almost all cases (98.1 % [95 % CI = 95.8-99.6 %]). Cardiac myxoma was mostly prevalent in left atrium (85.3 % [95%CI = 83.3-87 %]) and predominantly with pedunculated morphology (75.6 % [95%CI = 64.1-84.3 %]). Post-tumor excision outcomes were excellent, with an early mortality of 1.27 % (95 % CI = 0.8-1.8 %), late mortality rate of 4.7 (95 % CI = 2.5-7.4) per 1000 person-years, and recurrence rate at 0.5 (95 % CI = 0.0-1.1) per 1000 person-years. Tumor excision is warranted in a timely manner once the cardiac myxoma diagnosis is established.
