Summary
Peripheral primitive neuroectodermal tumours (PNETs) are rare, aggressive cancers. This report details the first known case of PNET occurring in the tongue, highlighting its unusual location.
Area of Science:
- Oncology
- Pathology
- Genetics
Background:
- Peripheral primitive neuroectodermal tumours (PNETs) are part of the Ewing sarcoma family.
- PNETs are characterized by high aggressiveness and a poor prognosis.
- Diagnosis relies on neural marker immunostaining and the t(11;22) translocation.
Observation:
- This study reports the first documented case of PNET originating in the tongue.
- The tumour presented with hallmark features of PNET, including specific neural markers and chromosomal abnormality.
Findings:
- A rare case of peripheral primitive neuroectodermal tumour was identified in the tongue.
- The diagnosis was confirmed through immunohistochemistry and genetic analysis, revealing the characteristic t(11;22) translocation.
Implications:
- This case expands the known anatomical sites for PNET occurrence.
- Understanding PNETs in rare locations is crucial for accurate diagnosis and treatment planning.
- Further research may elucidate factors contributing to PNET development in diverse anatomical sites.

01:01Tongue
The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
00:49The Tongue and Taste Buds
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
01:26Assessment 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.

01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:22Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
