Summary
A rare case of malignant paraganglioma presented in a 50-year-old male with unusual symptoms including eyelid swelling and nosebleeds. Diagnosis was confirmed via biopsy of a nasopharyngeal mass.
Area of Science:
- Oncology
- Pathology
- Otorhinolaryngology
Background:
- Malignant paragangliomas are rare neuroendocrine tumors.
- Presentation can be atypical, mimicking other head and neck malignancies.
- Early diagnosis is crucial for effective management.
Purpose of the Study:
- To report a rare case of malignant paraganglioma.
- To highlight the diagnostic challenges and unusual presentation.
- To emphasize the importance of thorough histopathological examination.
Main Methods:
- Clinical presentation: 50-year-old male with eyelid swelling, epistaxis, and post-auricular swelling.
- Diagnostic procedures: Posterior rhinoscopy, Fine Needle Aspiration Cytology (FNAC), and incisional biopsy.
- Histopathological examination of nasopharyngeal mass.
Main Results:
- Posterior rhinoscopy identified a polypoidal mass in the nasopharynx.
- FNAC suggested metastatic undifferentiated carcinoma.
- Histopathology confirmed malignant paraganglioma of the nasopharynx.
Conclusions:
- Malignant paraganglioma can present with varied and uncommon symptoms.
- Differentiating from metastatic carcinoma requires careful histopathological analysis.
- This case underscores the rarity and diagnostic complexity of nasopharyngeal malignant paraganglioma.

01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.

01:20Pharynx
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

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.

01:24Nose and Nasal Cavity
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
