A 20-year-old female presents with a painless, progressive, normal color smooth surface sublingual swelling extending to chin that had gradually increased in size over the preceding 2 months, which severely impaired her speech and swallowing. Fine-needle aspiration biopsy was suggestive of benign cystic lesion. Following surgical excision, the mass was found to contain a large amount of sebaceous keratin material removed along with the entire capsule of the cyst. Definitive diagnosis was confirmed with histological examination. We report a case of dermoid cyst treated surgically through an intra-oral approach by preserving and relocating the Wharton's duct using micro-surgical repair to the floor of the mouth, thereby leading to a good cosmetic and functional result for the patient.

A mature cystic teratoma is a mass with heterogeneous appearance, consisting of adult tissue with two or three layers: endoderm, mesoderm, and ectoderm. It is a rare, benign transformation of somatic tissue most commonly found in the sacrococcygeal region and may resemble an uncomplicated spina bifida on prenatal ultrasonography. In this case report, we describe a female newborn with an extremely rare mature cystic teratoma in the thoracolumbar region. She presented prenatally with a preliminary diagnosis of meningomyelocele, diastematomyelia, and Chiari II malformation and a possible teratoma. However, a mass containing solid glandular tissues and bony calcifications approximately 3 × 4 cm in size was observed in the thoracolumbar region upon birth. During surgical resection, no nerve roots were found in the associated meningocele. The patient retained full lower body function postoperatively following surgical excision of the thecal sac and teratoma.

BACKGROUND
Benign mature teratomas are the most common type of anterior mediastinal germ cell tumor. Mature intrapericardial teratomas are generally diagnosed during infancy because of symptoms of cardiac compression. In contrast, mature adult intrapericardial teratomas are extremely rare, accounting for less than 1% of mature intrapericardial teratomas. We describe herein a case of a mature intrapericardial teratoma in an asymptomatic adult.
CASE PRESENTATION
A 52-year-old woman was found by computed tomography during a health checkup to have an anterior mediastinal mass. She was asymptomatic and hemodynamically stable with no evidence of heart failure. The preoperative provisional radiological diagnosis was a mature intrapericardial teratoma. A median sternotomy revealed an approximately 5-cm diameter protruding intrapericardial mass with a smooth surface. The mass was completely resected. Histopathological examination resulted in a diagnosis of a mature intrapericardial teratoma. The patient did well and has no evidence of recurrence 5 years after surgery.
CONCLUSIONS
Mature intrapericardial teratomas in adults are extremely rare. Given the risks of malignant transformation, rupture, compression of the heart, and infection, excision is indicated to prevent development of serious manifestations.

Review
BACKGROUND
Pseudomyxoma peritonei (PMP) is a rare, progressive, slowly growing, inadequately understood neoplasm with a 5-year progression-free survival rate of as low as 48%. It is characterized by varying degrees of malignancy and the production of mucinous and gelatinous structures. Typically, the development of pseudomyxoma peritonei is associated with the rupture of appendiceal mucinous tumors and other gastrointestinal or ovarian mucinous tumors. The goal of our literature review was to identify various aspects that characterize the ovarian causes of pseudomyxoma peritonei.
MATERIALS AND METHODS
The authors performed an extensive literature search between 1 February 2024 and 2 March 2024 on the following databases: Pubmed, Scopus, Oxford Journals, and Reaxys, and the findings were summarized into seven main clinical and paraclinical situations.
RESULTS
According to our research, the main instances in which pseudomyxoma peritonei can be triggered by an ovarian cause are the following: (1) mucinous cystadenoma; (2) mucinous ovarian cancer; (3) colon cancer with ovarian metastasis; (4) malignant transformation of an ovarian primary mature cystic teratoma; (5) appendiceal mucocele with peritoneal dissemination mimicking an ovarian tumor with peritoneal carcinomatosis; (6) mucinous borderline tumor developing inside an ovarian teratoma; and (7) the association between a mucinous bilateral ovarian cancer and a colonic tumor.
CONCLUSIONS
In our study, we aimed to provide a comprehensive overview of the ovarian causes of pseudomyxoma peritonei, including its epidemiology, imagery characteristics, symptoms, current treatment, and promising future therapies, in the hopes of finding feasible solutions, as a lack of understanding of this mucus-secreting malignant disease increases the risk of delayed diagnosis or uncontrolled deterioration.

American Journal of Obstetrics and... Apr 2024Mature cystic teratomas represent nearly 60% of benign ovarian neoplasms across all age groups.
BACKGROUND
Mature cystic teratomas represent nearly 60% of benign ovarian neoplasms across all age groups.
OBJECTIVE
This study aimed to update existing descriptive studies of ovarian teratomas, including the epidemiology, rate of torsion or malignancy, and treatment modalities in a large modern cohort of patients.
STUDY DESIGN
This was a retrospective cross-sectional study of all pathology-confirmed cases of ovarian teratoma that underwent surgery at 1 tertiary care institution from 2004 to 2015. Patient demographics, ovarian cyst characteristics, surgical approach and timing, rate of spillage, and surgical complications were examined.
RESULTS
A total of 1054 cases of ovarian teratoma were identified during the study period. There were 113 cases (10.7%) of bilateral teratoma. The mean age at diagnosis was 38 years. The average cyst size was 6.26 cm. The overall rate of torsion was 5.6%, with a higher rate of torsion with increasing cyst size. More than 70% of cases were treated with minimally invasive surgery, which was associated with decreased perioperative complications but an increased risk of cyst spillage. Among 394 patients with cyst spillage, only 1 patient developed chemical peritonitis. The malignant transformation rate of mature cystic teratoma in this cohort was 1.1%. This cohort included 100 pregnant women with mature teratoma. Pregnant patients were more likely to have minimally invasive surgery in the first trimester of pregnancy and more likely to undergo laparotomy in the second or third trimester of pregnancy.
CONCLUSION
Similar rates of bilaterality, torsion, malignant transformation, and struma ovarii in ovarian teratomas were found in this large modern cohort compared with previous literature. Most cases of ovarian teratoma can be managed laparoscopically, which is associated with a lower surgical complication rate. Despite the increased risk of cyst spillage with a minimally invasive approach, chemical peritonitis is a rare complication.

INTRODUCTION
Adult sacrococcygeal teratoma (SCT) is a rare disease that is not easily detected or easily missed, and its treatment is based on surgery, including transabdominal, transsacral, or a combination of both, but there are no clear guidelines for diagnosis and treatment. We share a case of Altman type III SCT in order to provide more reference protocols for the diagnosis and treatment of adult SCT, and more importantly to increase our understanding of different types of SCT cases in adults.
PATIENT CONCERNS
Our patient was a 31-year-old adult woman who underwent complete surgical resection of a cystic mature teratoma of the right ovary 8 years ago and is currently 13 months postpartum without menstruation, usually with a feeling of anal bulge, with symptoms such as constipation.
DIAGNOSIS
We diagnosed SCT by vaginal ultrasonography, computed tomography and magnetic resonance imaging (MRI); benign tumors were considered in the results of serum tumor markers.
INTERVENTIONS
We chose the surgical approach of laparoscopic transabdominal-sacrococcygeal approach to completely remove the patient SCT and coccyx.
OUTCOMES
The location of SCT is concealed and the clinical symptoms are not obvious. Vaginal ultrasonography, CT and MRI can not only improve the diagnostic rate of SCT, but also understand the size and mass of SCT, providing an exact basis for clinicians to select the laparoscopic transabdominal-sacrococcygeal approach.
CONCLUSION
Our sharing increases the reports of rare cases of teratoma with the same histological findings in different organ tissues of the same patient at different times, whether this occurs incidentally requires more case reports and further basic research; in addition, the laparoscopic transabdominal-sacrococcygeal approach is a safe and effective surgical approach for the treatment of Altman type III SCT in adults; finally, this case reminds us that SCT may not affect pregnancy and pregnancy outcomes and provides a reference for the selection of interventions for SCT with pregnancy.

This case report presents a unique and challenging scenario involving the diagnosis and management of a sublingual dermoid cyst in a 12-year-old male with autism disorder. Dermoid cysts within the oral cavity are exceptionally rare entities, constituting less than 0.01% of all oral cavity cysts. In addition, their co-occurrence with neurocognitive disorders further complicates the diagnostic process. The patient's clinical presentation was marked by recurrent epistaxis and behavioral changes, which were compounded by his communication limitations due to autism disorder. A thorough physical examination revealed a sublingual mass causing tongue displacement. However, due to the patient's inability to effectively communicate symptoms, parental input played a pivotal role in constructing the clinical narrative. Imaging techniques, including computed tomography (CT) and magnetic resonance imaging (MRI), provided essential insights into the cyst's size, location, and structural characteristics. The successful integration of these modalities aided in achieving a definitive diagnosis. The subsequent intraoral surgical excision of the 6.5 cm cyst yielded a positive outcome, with an uneventful recovery and a six-month follow-up demonstrating no signs of recurrence. This report underscores the significance of multidisciplinary collaboration in navigating the complexities of diagnosing and managing rare oral lesions in patients with neurocognitive disorders. The confluence of two rare conditions necessitates a tailored approach that takes into account communication barriers and the patient's overall well-being. This case offers valuable insights to healthcare practitioners, highlighting the importance of leveraging advanced imaging technologies and adapting strategies to address the unique challenges posed by such cases. By presenting this exceptional clinical scenario, this report contributes to the medical community's understanding of nuanced diagnostic processes and patient-centered management techniques.

BACKGROUND
Colorectal cancer (CRC) is one of the most common cancers worldwide, and screening colonoscopy has led to a decreasing incidence rate. However, the incidence of CRC is increasing among young people, especially adolescents and young adults (AYAs) who are not routinely screened. Although CRC is the fourth most common cancer among AYAs, it is extremely rare. In younger patients, CRC is often diagnosed later, and the proportion of patients with advanced CRC is higher than that in older patients. We herein present a case of poorly differentiated mucinous carcinoma of the ascending colon complicated by bilateral ovarian mature cystic teratomas (MCTs) in an AYA.
CASE PRESENTATION
A 17-year-old female patient presented with a chief complaint of abdominal pain and diarrhea that had persisted for more than 3 years. Colonoscopy revealed circumferential wall thickening of the ascending colon, and colonic biopsy revealed a mucous mass and findings of adenocarcinoma, predominantly signet ring cell carcinoma. Abdominal computed tomography (CT) and pelvic magnetic resonance imaging (MRI) showed bilateral ovarian tumors. Laparoscopic right hemicolectomy and enucleation of bilateral ovarian tumors were performed. Although the ascending colon cancer formed a large mass, there were no signs of peritoneal dissemination or direct invasion to the surrounding organs. Microscopically, the ascending colon was a poorly differentiated mucinous carcinoma with signet ring cell carcinoma and lymph node metastasis (9/42). The ovarian tumors were diagnosed as MCTs without any malignant components. The pathological diagnosis was ascending colon cancer (pT4aN2bM0, pStage IIIC) and bilateral ovarian MCTs. Microsatellite instability (MSI) testing was negative, and there were no gene mutations in either RAS or BRAF. Postoperative adjuvant chemotherapy with oxaliplatin and 5-FU was started.
CONCLUSIONS
We presented a case of locally advanced ascending colon cancer in a 17-year-old female patient. CRC rarely occurs in AYAs. However, the incidence has gradually increased in recent years. It should be considered as a differential diagnosis for young patients with long-term abdominal symptoms of unknown cause.
