Cervicofacial cystic lymphangiomas in 17 childrens: A case series.

Introduction: Cystic lymphangiomas are rare dysembrioplasias that occur mostly in children. Although benign, these tumors remain potentially life-threatening, due to the possible compression of the upper airway. The management of cystic lymphangiomas is still somewhat controversial, with surgery generally being the first-line treatment. Patients and methods: 17 patients were included in this retrospective study, all aged less than 18 years old and treated for head and neck cystic lymphangiomas at our department between 2007 and 2017. All these patients had received surgical treatment alone. The relevant data were analyzed with SPSS software. Results: 17 patients were included, with a sex ratio M/F of 1,4, and an average age of 4 years old. Complete resection of the tumor could only be completed in 12 patients. No postoperative complications were observed in our series. All the patients were followed for a minimum of 2 years after treatment. Conclusion: Cystic lymphangiomas are rare tumors of mysterious origins. The main symptom is swelling of the affected area. In our series, the results of the surgery were promising and consistent with results reported in the literature. A follow-up study with a larger population could be interesting, to further examine potential prognostic factors.

Entirely endoscopic resection of a complicated juvenile psammomatoid ossifying fibroma of the paranasal sinusitis: Case report and review of the literature.

INTRODUCTION: Juvenile ossifying fibroma (OF) is a benign fibro-osseous tumor, affecting the bones of the face. It's locally very aggressive, with a strong tendency to recur. We report a case of a juvenile psammomatoid ossifying fibroma (JPOF) complicated with exophthalmos undergoing an entirely endoscopic resection. CLINICAL PRESENTATION: A 14-years-old, young woman presented with a 7 months history of headache and right chronic tearing complicated with exophthalmos. Nasal endoscopy revealed a polylobed mass filling the right nasal cavity, the ophthalmic examination showed an isolated exophthalmos. CT scan revealed a well-limited benign mass covered by a thick shell of bone, pushing out the orbital lamina papyracea responsible for a grade 1 exophthalmos. On the facial MRI, we excluded intracranial or intraorbital involvement. A biopsy of the mass describes a psammomatoid juvenile ossifying fibroma. The patient underwent endoscopic transnasal approach with image-guided neuro-navigation system. CLINICAL DISCUSSION: JPOF is an aggressive variant of ossifying fibroma occurring predominantly in children with a predilection for the paranasal sinuses. CT scan images show a characteristic well-limited benign expansile mass covered by a thick shell of bone, but sometimes it's mistaken for a mucocele. MRI helps with excluding intracranial or intraorbital involvement. Endonasal endoscopic approaches have been increasingly used and it tends to become the new standard of care. CONCLUSION: Treatment consists of complete surgical removal; incomplete resection is associated with a high local recurrence rate. Clinician should keep in mind the need for clinical and radiological follow-up for many years.

Undifferentiated nasopharyngeal cancer extending to maxillary sinus: a case report.

Undifferentiated nasopharyngeal cancer of the cavum (UCNT) is the most frequent neoplasm of the nasopharynx, having a close relationship with exposure to Epstein-Barr virus. It has a high potential for locoregional or distant invasion which are the cause of some treatment failures. The extension to the maxillary sinus is rarely described. We report here the case of a 38-year-old patient with headaches associated with epistaxis, left otalgia and facial pain. Examination by anterior rhinoscopy objectively revealed a polylobed ulcerating mass. Otoscopic examination revealed a left seromucous otitis media. Computed tomography showed a voluminous tumour process in the infra temporal fossa and nasopharynx with significant locoregional extension particularly in the maxillary sinus. Pathological examination revealed an UCNT of the cavum and the patient was classified as T4N2M0. The patient received chemoradiotherapy, with wide irradiation of the cervical lymph node areas. The deep localization of the cancer of the cavum, which is difficult to examine, requires a diagnostic and extension work-up, both endoscopic and radiological, which is an important step in the diagnostic and therapeutic management.

Bioactive compounds and antioxidant activity of Rhaponticum acaule (L.) DC.

Rhaponticum acaule (L.) DC. is a medicinal plant commonly used for the treatment of some illnesses such as gastrointestinal infections. In this work, we report the composition of different parts of this plant on phenolic compounds, their quantification, and antioxidant activity. The obtained results reported that methanolic extracts of the three parts studied revealed high phenolic contents. For flavonoid contents, the highest contents were reported in organic extracts of leaf part. In addition, results obtained from the study of the antioxidant activity showed that methanolic extract of root presented the highest activity, in DPPH• scavenging ability test with an IC50 of 0.31 ± 0.04 mg/mL and in FRAP test with an EC50 of 1.06 ± 0.02 mg/mL. The RP-HPLC-PDA analysis revealed the presence of five phenolic acids (sinapic, caffeic, chlorogenic, ferulic and syringic acids), one flavanone (naringenin), one flavonol (rutin) and vanillin.
