Congenital Cervical Teratoma in Neonates Case Report and Review
Bibliographic record
Abstract
Cervical teratomas are uncommon neoplasms. Although these lesions are histologically benign they are usually large and may cause airway obstruction. Cervical teratomas are usually diagnosed at birth. In-utero diagnosis is possible by prenatal ultrasound which assists in planning early airway management and surgical intervention. Mortality is significant but prognosis is good with airway control and complete surgical excision. However, pressure injury of contiguous structures can limit resectability and adversely affect outcome. Malignant cervical teratoma with metastasis has been reported mostly arising in adults with poor outcome. We present nine cases of neonatal cervical teratoma identified at two institutions between 1984 and 1996. One patient died before surgical intervention. All others underwent resection. There was one intraoperative death and one postoperative death. The remaining six patients did well postoperatively with no significant sequelae with 3 to 14 years follow-up. Zusammenfassung Zervikale Teratome sind ungewöhnliche Tumoren. Obwohl die Geschwülste histologisch gutartig sind, verursacht ihre Größe häufig Atemwegsobstruktionen. Die zervikalen Teratome werden gewöhnlich bei der Geburt diagnostiziert, aber auch eine pränatale Diagnostik mittels Ultraschall ist möglich und notwendig, um einen optimalen Entbindungsweg festzulegen. Die Mortalität ist zwar erhöht, die Prognose bei gutartigen Teratomen jedoch gut, wenn eine vollständige chirurgische Entfernung gelingt. Diese kann allerdings bei Einbezug wichtiger benachbarter Strukturen schwierig sein. Auch durch Druckatrophie bedingte Veränderungen können die Prognose beeinträchtigen. Vor allem bei Erwachsenen werden auch maligne zervikale Teratome mit Metastasierung beschrieben, in der vorliegenden Arbeit werden 9 Fälle angeborener zervikaler Teratome, die zwischen 1984 und 1996 diagnostiziert wurden, vorgestellt. Ein Patient starb vor dem chirurgischen Eingriff, bei den anderen 5 konnte eine Resektion durchgeführt werden. Trotzdem kam es zu einem intraoperativen und einem postoperativen Todesfall. Die sechs verbleibenden Patienten zeigten 3-14 Jahre nach dem operativen Eingriff keine Probleme.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
