Insights
A rare case of persistent adenoiditis revealed an unexpected island of cartilage in the nasopharynx. This finding offers insights into skull base and nasopharyngeal embryological development.
Area of Science:
- Otorhinolaryngology
- Developmental Biology
- Surgical Pathology
Background:
- Persistent adenoiditis can present diagnostic challenges.
- Computed tomography (CT) scans are often used for pre-operative assessment of adenoid tissue.
Observation:
- A 21-year-old male with persistent adenoiditis underwent imaging and surgery.
- Histologic examination of the adenoid tissue revealed an unexpected mature island of hyaline cartilage.
Findings:
- The resected adenoid tissue showed significant lymphoid hyperplasia.
- A distinct, mature island of hyaline cartilage was identified within the hyperplastic lymphoid tissue.
Implications:
- This case suggests a potential link between pharyngeal cartilage remnants and adenoid pathology.
- Understanding this anomaly may shed light on the embryological development of the skull base and nasopharynx.
Abstract:
A 21-year-old white male presented with persistent adenoiditis. A computed tomography (CT) scan with contrast was performed and was interpreted as normal. An adenoidectomy was performed, and histologic examination demonstrated the unexpected presence of a mature island of hyaline cartilage surrounded by lymphoid hyperplasia. The nature of this anomaly is considered in respect to the embryological development of the base of the skull and nasopharynx.

Pharynx
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...

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Chronic Pharyngitis
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,...
