Primary Squamous Cell Carcinoma of the Thyroid

Area of Science:

• Oncology
• Head and Neck Surgery

Background:

• Primary squamous cell carcinoma of the thyroid (PSCCT) is an exceptionally rare malignancy.
• Fewer than 60 cases of PSCCT have been documented in medical literature.

Observation:

• A 66-year-old female presented with compressive symptoms and shortness of breath.
• Physical exam revealed thyromegaly and vocal fold immobility.
• Imaging showed an enlarged thyroid, cervical lymphadenopathy, subglottic stenosis, and pulmonary nodules.

Findings:

• Histopathology and immunohistochemistry confirmed PSCCT.
• The patient had metastatic disease to the lung and cervical spine.
• The patient died shortly after palliative chemotherapy initiation.

Implications:

• PSCCT is an aggressive malignancy with a poor prognosis.
• Accurate diagnosis requires histopathologic and immunohistochemical evaluation.
• Early diagnosis and rapid treatment are essential for potentially improving survival in PSCCT patients.
