A giant primary thyroid fibrosarcoma in an octogenarian

Area of Science:

• Endocrinology
• Oncology
• Surgical Pathology

Background:

• Giant goiters can cause significant compressive symptoms, impacting vital structures like the trachea and esophagus.
• Thyroid tumors, particularly sarcomas, are exceptionally rare, posing diagnostic and therapeutic challenges.

Observation:

• An 89-year-old patient presented with severe dyspnea and mild dysphagia attributed to tracheal and esophageal compression by a large goiter.
• The patient maintained a euthyroid state despite the substantial thyroid mass.

Findings:

• A total thyroidectomy was performed, achieving successful decompression and tumor removal.
• Histopathological examination confirmed the presence of a Grade 1 fibrosarcoma (G1), an exceedingly rare thyroid malignancy.

Implications:

• This case highlights the importance of considering rare thyroid malignancies in the differential diagnosis of compressive neck masses.
• Successful surgical management of such rare tumors can lead to significant symptom relief and improved patient outcomes.
• Further research into the etiology and optimal treatment strategies for thyroid fibrosarcoma is warranted due to its rarity.
