Abstract:

Yolk sac tumour is a rare malignant tumour of germ cell origin that usually arises from the gonads. It is extremely rare in the head and neck. We present a case of a yolk sac tumour that involved the floor of the mouth in a 14-month-old Chinese girl. The diagnosis was confirmed by histological examination that showed characteristic Schiller-Duval bodies, and immunohistochemical examination that showed α-fetoprotein being expressed within the cytoplasm of the neoplastic cells. The patient died 4 months postoperatively. To our knowledge, this is the first case of a yolk sac tumour of the floor of mouth that has been reported in an English journal.

Assessment of the Mouth

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Oral Cavity

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
