Parathyroid adenoma associated with neurofibromatosis type 1

Association between atypical parathyroid adenoma and neurofibromatosis.

Primary hyperparathyroidism is a disease characterized by excessive production of parathyroid hormone (PTH), which is due to a parathyroid adenoma in 85% of cases. An atypical parathyroid adenoma, with some histopathological features of parathyroid carcinoma, may be found in some of the cases, although it may not fulfill all the criteria for this diagnosis. Neurofibromatosis type 1 (NF1) is an ...

papillary thyroid carcinoma associated with parathyroid adenoma

concomitant papillary thyroid cancer and parathyroid adenoma is rare. we report a 55 years old female with papillary cancer admitted for surgery. preoperative laboratory findings revealed hypercalcemia and then primary hyperparathyroidism. thyroidectomy, neck dissection and excision of parathyroid adenoma were performed. histological examination revealed parathyroid adenoma. serum calcium retur...

Equatorial Staphyloma Associated with Neurofibromatosis Type 1

We report a case of a 38-year-old man who presented with a recently self-detected lump under his left eyebrow. Previous ophthalmological history was unremarkable except for unilateral high myopia (left eye) since childhood. The appearance of the left eye was seemingly normal; however, with the top lid pulled up on downward gaze, a dark brown bulge emerged. The bulge was 10 × 7 mm and approximat...

Parathyroid adenoma Localization

 Background: Bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. But surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance....
