Thyroid Papillary Carcinoma and Hyperthyroidism: A Case Study

Background: Concurrent thyroid cancer and hyperthyroidism is a rare finding. The frequency of this association is very variable. A rare case of papillary thyroid cancer associated with hyperthyroidism is described here. Case: A 49-year-old male presented to the authors’ outpatient clinic with complaints of a painless left-sided anterior neck swelling that had persisted for the past 8 months. He also reported weight loss for the same duration. The anterolateral swelling was non-tender, asymmetrical, mobile, and rubbery. Investigations: Biochemical analysis confirmed hyperthyroidism. Ultrasound examination of the neck showed a well-defined, solid, and cystic lesion in the left lobe and isthmus of thyroid gland. The solid portion had few specks of calcification. A radioactive thyroid scan showed increased tracer uptake in the left lobe. Papillary carcinoma of thyroid origin was discovered after fine-needle aspiration of the left anterior cervical lymph node. After preparation, a total thyroidectomy was done. Examination of histopathology confirmed papillary thyroid carcinoma. Treatment: Following radioactive thyroid ablation, the patient was started on suppressive doses of thyroxine daily. Conclusion: Although thyroid cancer with hyperthyroidism is a rare finding, it should not be disregarded. To avoid missing this unusual yet uncommon discovery, a detailed history and physical examination should be performed, as well as all required investigations.

Thyroid Gland Abscess: Uncommon complication

The thyroid gland is naturally resistant to infectious processes, which explains the rarity of thyroid abscess. It represent about 0.1% of the surgical thyroid pathology. We report in this article a case of thyroid gland abscess in a 61 year-old man who was followed for diabetes and hypothyroidism with poor adherence, who consulted in emergency department for acute neck swelling. CT scan showed a fluid collection of the left thyroid lobe. The patient was operated, and histopathological examination concluded of laryngeal carcinoma associated to thyroid papillary carcinoma.

Infiltration of thyroid papillary cancer tissue with myeloid leukemic cells: a case report

Background Extramedullary leukemia, also known as myeloid sarcoma, is a rare form of acute myeloid leukemia and often accompanies bone marrow involvement. Myeloid infiltration of the thyroid gland is extremely rare. Here, a unique case in which thyroid cancer tissue was infiltrated with myeloid cells is presented. Case presentation We present a case of thyroid papillary cancer infiltrated by blastic cells and bilateral breast and axillary myeloid sarcoma in a 30-year-old Caucasian female patient with a history of osteosarcoma and MDS-RAEB2. The patient firstly received 6 cycles of chemotherapy for osteosarcoma, and allogeneic hematopoietic stem cell transplantation was performed after anthracycline-based chemotherapy due to MDS-RAEB2. The patient remained in remission on follow-up in terms of both osteosarcoma and MDS-RAEB2. Malignant features (Bethesda VI) were observed in the fine needle aspiration biopsy performed from a newly developed firm, fixed thyroid nodule approximately 4–5 cm in length in the left thyroid lobe. Because of the Bethesda VI thyroid nodule, the patient underwent total thyroidectomy. In the pathological evaluation, CD34-, CD117-, MPO-, and HLA-DR-positive blastic cells which infiltrated into follicular variant papillary thyroid carcinoma were detected. In the evaluation performed due to blastic cell infiltration, multiple lesions showing increased 18-fluorodeoxyglucose activity in bilateral breast and axillae were detected. Myeloid sarcoma was found as a result of tru-cut biopsy from these lesions. A fungal cystic lesion was detected in the frontal region of the patient who developed altered consciousness after the second cycle of treatment of myeloid sarcoma. During her follow-up in the intensive care unit, she died of cranial septic embolism and acute infarction. Conclusions Here, we present a very interesting case that is the first. A staged approach to diagnosis with methods including immunohistochemical staining, radiological imaging methods, and cytogenetic and molecular analyses can help make the definitive diagnosis.
