RETROSTERNAL GOITRE WITH VARIED HISTOMORPHOLOGY: A CLINICOPATHOLOGICAL CASE REPORT
The term such as retrosternal or substernal is used when a goitre extends below thoracic inlet. Retrosternal goitre is rare and accounts for 5–20% of thyroidectomy patients. Majority of the patients present with symptoms of dyspnoea as in our case. Also, patients can come with change of voice, stridor and a huge swelling. Most of the cases of retrosternal goitre can be removed with conventional collar incision, however sternotomy may be required in few cases. Our patient was euthyroid at presentation and a right hemithyroidectomy was done for her. A detailed histopathological evaluation (HPE) showed evidence of long-standing Adenomatoid goitre with extensive hyalinization, thickened capsule and secondary degenerative changes in the right lobe of thyroid and evidence of chronic lymphocytic thyroiditis in the sections examined from the portion of isthmus. The procedure was uneventful. The patient was doing well after three months of clinical follow up.
