Thirty-two years old female G2P1A0 seen at our endocrinology clinic 9 years ago complaining of persistent menstrual irregularities associated to elevated prolactin values. MRI done revealed a pituitary microadenoma. However, she refused treatment for microprolactinoma. Four years afterwards, patient return complaining of recurrent episodes of headache. Repeated MRI showed a pituitary macroadenoma, so start on cabergoline treatment.Once more, patient was ...

Physical examination revealed a mildly tender right neck mass. He was clinically and biochemically euthyroid. Denied history of neck irradiation. No family history of thyroid disease or thyroid cancer. Excisional biopsy of right neck mass showed metastasic well differentiated papillary carcinoma...

Background: Acromegaly most commonly results from an excess production of GH and secondary increase in IGF1. More than 95% of the time from the pituitary gland, but the source of excess GH secretion may not necessarily be pituitary in origin. Ectopic acromegaly may arise due to neuroendocrine tumors by production of GHRH and in <0.5% of the cases from ectopic pituitary remnants in the sphenoid sinus.Clinical case: We present a case of a 37 years old ...

Introduction: Isolated ACTH deficiency (IAD) is a rare entity characterized by secondary adrenal insufficiency with low levels of serum cortisol, decreased production of ACTH, adequate secretion of other pituitary hormones and normal pituitary structure on radioimaging. Due to the rarity of its occurrence the prevalence of IAD as a cause of secondary adrenal insufficiency has not been determined. To our knowledge 200 cases are described in the literature. Impairment of GH secr...

Hyperfunctional nodules of the thyroid are rarely associated with thyroid cancer, for these reason are rarely biopsied. Although multiple theories have being proposed, the relationship is still uncertain. After performing a MEDLINE literature search, we found in multiple retrospectives analysis, that patients with hyperthyroidism with hyperfunctional nodules have an estimated of 0.3–16.3% prevalence of malignancy. In our study forty-eight hyperthyroid cases were prospecti...
