CONGENITAL NASAL TERATOMA

Case Report

Introduction

Teratomas are true tumours arising from totipotential cells. They most commonly arise in the ovary or testis and occasionally may be seen in other locations like mediastinum and neck. Most teratomas of infancy and childhood arise in sacrococcygeal region or the gonads. Here we present and discuss a rare case of nasal teratoma. This condition may be misdiagnosed as nasal probosis lateralis from which it is differentiated by the normal development of the nose.

Case Report

A 4-months-old female child was brought to the ENT OPD with complaints of a pedunculated mass projecting from Rt nostril which was present since birth and was gradually increasing in size. The child also had occasional difficulty in breast feeding. Examination showed a 5 cm long fleshy pedunculated mass projecting from Rt nostril (Fig 1). It was firm in consistency, non tender, nonpulsatile did not increase in size on coughing or straining and did not bleed on touch. There was flaring of the Rt ala and widening of dorsum of nose. Examination of throat and neck was normal. Aural and ocular examination was also normal. Xray nasopharynx lateral view showed normal air column in nasopharynx. CT Scan did not show any sphenoidal or intracranial extension Surgical excision was advised but parents were unwilling.

Discussion

The word teratoma means “tumour like malformation”. Teratomas are true neoplasms that contain tissues foreign to the site of origin. It is now generally accepted that teratomas may arise from both germ cells and non germ embryonic cells. The haphazard arrangement of tissues with asynchronous maturation is believed to escape the controlling influence of the primitive streak notocord or adjacent structures. Teratomas grow aggressively and in head and neck they most commonly occur in the cervical region followed by nasopharynx [1]. Teratomas of nose and nasopharynx typically arise from lateral or superior walls and are of four type [2].

  • 1.
    Dermoid Cyst-Commonest form composed of ectoderm and mesoderm.
  • 2.
    Teratoid Cyst derived from all three germ layers but poorly differentiated.
  • 3.
    True teratoma-composed of all three germ layers with specific tissue differentiation and
  • 4.
    Epignathus in which well developed foetal parts are recognised.

Nasopharyngeal teratomas are pedunculated masses filling the nasopharynx and may have nassal or oropharyngeal extension. They present at birth. CT scan and MRI are critical to define the extent of the neoplasms and to exclude either a nasoencephalo meningocoele or intracranial extension of a sphenoid based teratoma through craniopharyngeal canal [3]. Malignant metastasizing teratomas are extremely rare in children but adult forms of teratomas are usually malignant. Treatment of nasal and nasopharyngeal teratomas is surgical removal. Preoperative planning with imaging is essential to determine full extent of the tumour. Preoperative bleeding is usually less due to poor vascularization and if removal is complete recurrence is rare [4].
