Isthmicoma

Isthmicoma is a rare type of tumor that originates from the isthmus of the thyroid gland. It is a subtype of follicular thyroid carcinoma, which is the second most common type of thyroid cancer.

Epidemiology

Isthmicomas are extremely rare, with only a few cases reported in the medical literature. They can occur at any age but are most common in adults aged 40-60 years. There is no known gender predilection.

Pathogenesis

The exact cause of isthmicoma is unknown. However, it is thought to arise from the follicular cells of the thyroid isthmus, which is a small bridge of thyroid tissue that connects the two lobes of the gland.

Clinical Features

Patients with isthmicoma typically present with a painless mass in the neck. Other symptoms may include difficulty swallowing, hoarseness, and shortness of breath.

Diagnosis

The diagnosis of isthmicoma is usually made by fine needle aspiration (FNA) biopsy of the thyroid mass. The biopsy sample is then examined under a microscope to look for cancer cells.

Treatment

The treatment for isthmicoma is usually surgical removal of the tumor. This is often followed by radioactive iodine therapy to destroy any remaining cancer cells.

Prognosis

The prognosis for patients with isthmicoma is generally good, especially if the cancer is detected early and treated promptly.
