Non-secretory medullary thyroid carcinoma with laryngotracheal invasion: a case report and review of the literature.

Background

Medullary thyroid carcinoma (MTC) is a rare and aggressive type of thyroid cancer. Patients with this condition typically manifest palpable neck swelling and compressive symptoms. Biochemical evaluation and neck ultrasound play vital roles in diagnosis. The management options differ based on the extent of the disease.

Case Description

This paper describes a 47-year-old male patient diagnosed with MTC invading the trachea and larynx. He presented with a 5 cm × 5 cm hard thyromegaly on the right side with right-sided level IV lymphadenopathy, measuring approximately 2 cm. He underwent total thyroidectomy, total laryngectomy, and bilateral neck dissection. Postoperatively, the patient developed a neck abscess and pharyngocutaneous fistula (PCF), which was managed surgically and had a satisfactory outcome. After 128 days of inpatient care, he was discharged in a stable condition with resolution of complications and had no evidence of local recurrence during the 6-month follow-up.

Conclusions

MTC is a rare type of thyroid neoplasia that can manifest with various symptoms resulting from either the primary lesion or secondary invasion. Surgery remains the mainstay of treatment, however, there are limited options and no approved adjuvant therapies for patients with disseminated MTC. Complications that arise after total thyroidectomy and laryngectomy can be noteworthy and demand careful surveillance and immediate treatment to prevent further deterioration.
