Mature cystic teratoma of mediastinum compressing the right atrium in a child: A rare case report

Abstract
in English, Arabic

Teratomas or Germ cell tumours (GCTs) are interesting because of their obscure origin, bizarre microscopic appearance and unpredictable behaviour. Mediastinal teratoma is a slowly growing and rare tumour found in children that is diagnosed incidentally in asymptomatic patients. Most of the symptoms are related to mass compression effects such as chest pain, cough, respiratory distress and dysphagia. We report a 5-year-old male child who presented with a history of foreign body ingestion, sternal and left upper quadrant pain and vomiting without respiratory distress. The patient was incidentally found to have an anterior mediastinal mass compressing the right atrium and was diagnosed by histopathological examination as having a mature cystic teratoma of the mediastinum. The patient was successfully treated by the surgical resection of the tumour.

الأورام المسخية (التيراتومات) أو أورام الخلايا الجنسية هي أورام مثيرة للاهتمام بسبب أصلها الغامض، ومظهرها المجهري الغريب وسلوكها غير المتوقع في بعض الأحيان. والأورام المنصفية المسخية أورام غير شائعة لدى الأطفال. وهي أورام بطيئة النمو يتم تشخيصها صدفة عند مرضى لا تظهر عليهم أعراض. ومعظم الأعراض إن وجدت، تكون ذات علاقة بأثر ضغط الكتلة على الأنسجة المجاورة مثل ألم الصدر، والسعال، وضيق التنفس وصعوبة البلع. نقدم في هذه الورقة تقرير حالة طفل ذكر يبلغ من العمر ٥ سنوات، قَدِم بألم في منطقة القص، والربع العلوي الأيسر مع تقيّؤ بدون ضيقة تنفسية. تبين أن المريض لديه كتلة في المنصف الأمامي ضاغطة على الأذين الأيمن، وتم تشخيصها بالفحص النسيجي على أنها ورم مسخي كيسي ناضج في المنصف. وتم علاج المريض بنجاح بالاستئصال الجراحي الكامل للورم.
