AI Article Synopsis

  • Insular carcinoma of the thyroid (ICT) is a rare and hyperfunctioning thyroid tumor, with a reported case involving a 65-year-old woman who presented with neck masses and symptoms of hyperthyroidism.
  • The patient underwent total thyroidectomy and radical neck dissection after being diagnosed with poorly differentiated ICT through histopathology.
  • The case reinforces that while ICT is uncommon, it can present with prolonged signs of hyperthyroidism, and total thyroidectomy is the preferred treatment approach.

Article Abstract

Introduction: Insular carcinoma of thyroid (ICT) is a rare pattern of thyroid tumor. Being hyperfunctioning makes the condition rarer. Here we reported a case of ICT associated with hyperthyroidism.

Case Report: A 65-year-old female presented with neck mass for 4 years. She had symptoms of thyrotoxicosis and received antithyroid treatment. She was referred for surgical management. She had multiple, non tender, mobile masses in the neck. Ultrasound showed midline multiple heterogenous mass lesions with multiple lymph nodes in right side of the neck largest one measuring 2×2cm. The patient was prepared for total thyrodectomy with radical neck dissection. The result of histopathology confirmed unifocal, poorly differentiated ICT. The post operative course was uneventful.

Conclusion: Insular carcinoma is a rare disease. It may present with long history of signs and symptoms of hyperthyroidism. Total thyroidectomy is the main line of treatment.

Rationale: The occurrence of refractory small cell lung cancer (rSCLC) with pancreatic metastasis is a relatively rare clinical condition, which is typically accompanied by a poor prognosis and rapid disease progression.

Patient Concerns: A 65-year-old male farmer from China was diagnosed with limited-stage small cell lung cancer (SCLC) 8 months ago. Following 6 cycles of EP chemotherapy, the patient's tumor response showed partial relief.

Importance: Upper gastrointestinal cancers such as gastric and esophageal cancers are rare malignancies with poor prognosis because it is usually diagnosed in latter stages. Presenting symptoms are frequently presumed pregnancy related rather than malignancy related. This review will raise awareness to consider these aggressive cancers in evaluating gastrointestinal complaints during pregnancy.

Background: Pulmonary sarcomatoid carcinoma (PSC) is a rare lung cancer characterized by early metastasis and invasion. It is predominantly diagnosed at a locally advanced or metastatic stage, hindering the possibility of surgical intervention. However, a standard treatment for advanced PSC remains unestablished.

Cerebral arteriovenous malformations (AVMs) are tangles of abnormal vessels with early arteriovenous (AV) shunting that can lead to intracerebral hemorrhage, seizures, neurologic deficit, or headache. To date, only a few cases of carcinomas metastasizing to pre-existing cerebral AVMs have been reported in the literature. However, renal clear cell carcinoma (RCC) brain metastases that exhibit early AV shunting, where AVM pathology is not present, are extremely rare.

Urological malignancies during pregnancy are exceedingly rare, with bladder cancer posing significant diagnostic and management challenges. This study describes a 28-year-old pregnant woman diagnosed with non-invasive papillary urothelial carcinoma, presenting with painless hematuria at 22 weeks of gestation. The diagnostic process included ultrasound and MRI, both of which confirmed a solitary polypoidal lesion.
