Oropharyngeal dermoid cyst in an infant with intermittent airway obstruction. A case report

Oropharyngeal teratoma: A case presentation and review of literature

Teratomas are true neoplasms derived from the three germ layers. They are relatively rare tumours. They present in the sacrococcygeal region, gonads and retroperitoneum commonly. We present the report of a 5-month-old infant who presented with a prolapsing oropharyngeal teratoma and literature review.

Autoamputated pharyngeal hairy polyp presented with aero-digestive obstruction: A case report

A pharyngeal hairy polyp (HP) is a rare benign mass that can be surgical detached with few complications. In this report, we describe a hairy polyp in a 7-day-old neonate presented with intermittent respiratory distress and feeding difficulties since birth. Neck computed tomography was performed, and demonstrated a well-defined pedunculated heterogeneous mass arising from the right lateral wall of the nasopharynx extending downward and nearly completely obstructing of the nasopharynx and oropharynx. The central part of the mass was found relatively dense surrounded by low attenuation fatty components with enhancement of the outer wall of the mass. The provisional diagnosis was pharyngeal HP. After autoamputation at the seventh day old, HP was analyzed via histopathology examination that showed a mixture of various ectodermal and mesodermal tissues including skin, cartilage, adipose and fibrous tissue. The patient fully recovered with no residual clinical features. We report this case to elucidate the possibility of this strange behavior of pharyngeal HP.

Oropharyngeal Hairy Polyp: A Case of Respiratory Failure in a Newborn

Hairy polyps, also known as dermoid polyps (DPs), are rare benign cystic lesions of bigerminal origin that may occur in several head and neck regions, including the oropharynx. Despite their benign histopathological nature, DPs may be life threatening, due to their upper airway location, and DPs represent one of the most unusual causes of respiratory distress during the neonatal period. In this paper, we describe a case of respiratory failure in a newborn with an oropharyngeal mass that was accidentally found during difficult intubation. Magnetic resonance imaging (MRI) detected a well-defined soft tissue pedunculated mass, arising from the left oropharynx wall, consistent with an oropharyngeal DP. The newborn had a prompt recovery after trans-oral mass removal. Our case underlines the importance of imaging in differential diagnosis of children’s respiratory distress, secondary to a variety of lesions within the region of the skull base or oropharynx. It allowed us to assess the origin of the lesion, as well as its relationship with the adjacent soft tissues, and to exclude intracranial extension, thus providing essential information for the surgical planning.

Obstructing in utero oropharyngeal mass: Case report of a lymphatic malformation arising within an oropharyngeal teratoma

An ex utero intrapartum treatment procedure was performed to deliver a fetus with a multiseptated, entirely cystic, 4.5 × 5.0 × 4.0-cm mass occupying the oropharynx and oral cavity with protrusion from the mouth. Surgical excision was performed, and final pathologic diagnosis revealed a lymphatic malformation arising within a cystic oropharyngeal teratoma. Lymphatic malformations are virtually indistinguishable radiologically from rare, purely cystic teratomata, and efforts have been made to distinguish between the two in utero because of differing available treatment modalities. This represents the first documented case in the literature of a lymphatic malformation arising from within an oropharyngeal teratoma.
