[A giant lipoma of parapharyngeal space in a child]. / Un volumineux lipome de l'espace parapharyng chez un enfant.

INTRODUCTION: Tumors of the parapharyngeal space are rare and composing a wide variety of histological types. The aim of this study was to report a case of giant parapharyngeal lipoma in a child and to present clinical, paraclinical, and treatment aspects. CASE REPORT: A 14-year-old child presented with a painless progressive mass on the right side of the upper neck. It was growing asymptomatically since 2 years. Cervical CT-scan and MR showed a low-density mass in the right parapharyngeal, consistent with a mass of adipose tissue origin. The mass was surgically removed via cervical-parotid approach. The fatty mass was completely excised. Histopathology confirmed it to be a lipoma. The patient has been followed up for three years, and there have been no signs of recurrence. CONCLUSION: Diagnostic orientation in parapharyngeals tumors is necessary for better care. This guidance is being facilitated through imaging advances. Their surgical approaches and complete excision depend on volumes, localizations and their proximity to neurovascular structures.

Mastoid osteoma: report of two cases.

INTRODUCTION: Mastoid osteoma is a rare benign tumour. In this article, the authors report two new cases of mastoid osteoma and discuss the modalities of diagnosis and management. CASE REPORTS: Both patients presented with a retroauricular mass that had been slowly increasing in size over several years. The patients consulted for the cosmetic deformity induced by the lesion or moderate tenderness. The diagnosis was based on the clinical presentation and non-contrast CT. The osteoma was surgically resected in one patient. DISCUSSION/CONCLUSION: Mastoid osteoma is a rare, slowly growing, and usually asymptomatic benign tumour. Diagnosis is based on clinical findings and CT. Surgery is indicated for symptomatic or cosmetically unacceptable osteomas.

Congenital internal jugular phlebectasia.

INTRODUCTION: Congenital internal jugular phlebectasia corresponds to congenital dilatation of the vein without tortuosity. More than one hundred cases of phlebectasia involving the neck veins have been reported in the literature. The authors describe the clinical features, treatment and outcome of this anomaly. CASE REPORT: A six-year-old child with no particular past medical history presented with a two-year history of progressively enlarging mass on the right side of the neck. Physical examination revealed a non-pulsatile mass that was increased in size by all manoeuvres increasing intrathoracic pressure. Neck computed tomography confirmed the diagnosis of internal jugular vein phlebectasia. In the absence of complications, simple surveillance was advised with a follow-up of 20 months with no complications. DISCUSSION/CONCLUSION: Congenital internal jugular phlebectasia is a rare condition. Management must include imaging to confirm the diagnosis. Long-term surveillance is recommended and surgery is only required in the presence of complications.

[Pleomorphic adenoma of the nasal septum]. / L'adénome pléomorphe du septum nasal.

INTRODUCTION: The pleomorphic adenoma is the most common benign neoplasm of primary salivary glands. However, its intranasal localization is exceptional. We report a case of pleomorphic adenoma of the nasal septum. CASE REPORT: A 64-year-old man presented with a left rhinological syndrome with nasal obstruction. A facial CT-scan showed a heterogeneous tumor of the nasal septum obstructing the left nasal vestibule. The biopsy analysis proved the histological characteristics of a pleomorphic adenoma, and was further confirmed by immunohistochemical study. The lesion was completely removed by endonasal surgery. There was no recurrence 18 months after surgery. DISCUSSION: The treatment of nasal pleomorphic adenomas must take into account lesion localization, esthetic complications, and evolutionary potential of the lesions. Long-term follow-up is recommended because of the risk of recurrence or malignant degeneration.

[Basilingual ectopic-thyroid goiter]. / Goitre sur thyroïde ectopique basilinguale.

INTRODUCTION: Ectopic thyroid is a rare pathology characterized by thyroid tissue, located outside of the normal area. The aim of this study was to report a case of a basilingual ectopic-thyroid goiter and to present clinical, paraclinical, and treatment aspects. CASE REPORT: A 45-year-old woman presented with a mass located at the base of the tongue-hampering deglutition. A CT-scan revealed a tissular tumour. The biopsy proved this to be thyroid tissue. Cervical ultrasonography did not show the thyroid gland in normal location. A complete exeresis was performed by suprahyoid-surgical approach. The histopathological examination confirmed a non-malignant ectopic goiter. DISCUSSION: The etiology of ectopic thyroid is unknown. The location is possible anywhere on the pathway used during the course of embryonal development between the base of the tongue and the normal location. Scintigraphy is the best examination to detect ectopic-thyroid tissues and to show the absence of the thyroid in its normal location. The treatment for basilinguale-ectopic thyroid is surgery. If necessary, a medical treatment is associated. The surgical approach and preoperative tracheotomy are chosen according to volume, tumoral extension, and operative risks.
