A woman with Addison disease developed hyperpigmentation, headache, and nausea despite conventional replacement therapy with cortisone. Excessively elevated plasma adrenocorticotropic hormone (ACTH) with absence of response to administration of corticotropin-releasing factor (CRF), and roentgenological evidence of enlargement of the sella turcica, as well as detection of enlarged pituitary gland on magnetic resonance images, led to a diagnosis of ACTH-producing microadenoma, which was removed by transsphenoidal microsurgery. The specimen obtained at surgery evidenced corticotroph hyperplasia, as demonstrated by immunohistochemical staining for ACTH. Fine structure exhibited densely granulated cells with a few bundles of microfilaments and an abundance of large lysosomal bodies. Surgical removal of the hyperplasia alleviated the patient's symptoms, and hyperpigmentation faded remarkably. Her plasma ACTH level returned to normal, has remained normal for more than 3 years, and responds adequately to CRF administration.

We report the remission of primary gastric lymphoma of the mucosa-associated lymphoid tissue (MALT) type in two immunocompromised pediatric patients. Patient 1, a 14-year-old boy in an immunocompromised state of unknown cause, complained of repeated abdominal pain. Examinations revealed gastric MALT with local invasion and lymph node involvement. Serum anti-Helicobacter pylori (H pylori) antibody was positive. H pylori eradication was abandoned due to its adverse effects. The MALT lesion spontaneously regressed over the next 24 months without any treatment for lymphoma. Patient 2, a 6-year-old boy, underwent cord blood transplantation for the treatment of adrenoleukodystrophy. He was administered immunosuppressants for graft-versus-host disease after transplantation. Nausea and hematochezia appeared and further examinations revealed gastric MALT with H pylori gastritis. Treatment consisting of medication for the H pylori infection alone eradicated the H pylori and completely resolved the patient's MALT lesion, as well. Patients 1 and 2 were followed up over periods of 10 years and 3 years, respectively, without any signs of relapse. In conclusion, gastric lymphoma of the MALT type can be cured by conservative treatment even in immunocompromised pediatric patients.

Primary adrenal insufficiency is an endocrine disorder characterized by cortisol and aldosterone deficiency caused by destruction of the adrenal cortex. Adrenal crisis is a medical emergency with acute symptoms: nausea, vomiting, abdominal pain, fever, hypoglycemia, seizures, hypovolemic shock, and cardiovascular failure. It occurs in patients with chronic adrenal insufficiency who are exposed to additional stress, such as infection, trauma, or surgical procedures. Dental infection is a possible cause of adrenal crisis in patients with chronic adrenal insufficiency, so pediatric endocrinologists and pediatric dentists should be aware of this risk. The purpose of this report was to present a 6-year-old patient in whom Addison disease was diagnosed through adrenal crisis provoked by dental infection. The patient was treated with intravenous rehydration, intravenous hydrocortisone and antibiotics, and extraction of the infected primary tooth. Multidisciplinary approach and collaboration between the pediatric endocrinologist and the pediatric dentist are necessary to enable adequate medical and dental treatment in children with primary adrenal insufficiency.

The clinical syndrome idiopathic intracranial hypertension (IIH), also termed pseudotumor cerebri, consists of symptoms of headache, nausea, vomiting and visual field defects in combination with findings of papilledema. IIH is more commonly seen in overweight women where the rise in intracranial pressure is putatively a consequence of an endocrine-based disturbance of electrolytes. Less frequently, it can also occur in men and in the pediatric age group. Associated risk factors include primary and secondary aldosteronism, pregnancy, recombinant growth hormone (r-GH) therapy, oral contraceptives, obesity, vitamin A intoxication or deficiency, Addison disease, corticosteroid therapy or acute withdrawal of steroid therapy and Cushing disease. Herein, we review the association between these conditions and IIH working toward its having a unifying neuroendocrine hypothesis.

Primary adrenal insufficiency, or Addison disease, has many causes, the most common of which is autoimmune adrenalitis. Autoimmune adrenalitis results from destruction of the adrenal cortex, which leads to deficiencies in glucocorticoids, mineralocorticoids, and adrenal androgens. In the United States and Western Europe, the estimated prevalence of Addison disease is one in 20,000 persons; therefore, a high clinical suspicion is needed to avoid misdiagnosing a life-threatening adrenal crisis (i.e., shock, hypotension, and volume depletion). The clinical manifestations before an adrenal crisis are subtle and can include hyperpigmentation, fatigue, anorexia, orthostasis, nausea, muscle and joint pain, and salt craving. Cortisol levels decrease and adrenocorticotropic hormone levels increase. When clinically suspected, patients should undergo a cosyntropin stimulation test to confirm the diagnosis. Treatment of primary adrenal insufficiency requires replacement of mineralocorticoids and glucocorticoids. During times of stress (e.g., illness, invasive surgical procedures), stress-dose glucocorticoids are required because destruction of the adrenal glands prevents an adequate physiologic response. Management of primary adrenal insufficiency or autoimmune adrenalitis requires vigilance for concomitant autoimmune diseases; up to 50% of patients develop another autoimmune disorder during their lifetime.

Addison disease is a rare endocrine disorder, which typically presents with nonspecific symptoms including weight loss, fatigue, and nausea in conjunction with hyponatremia and hyperkalemia. This case demonstrates key diagnostic clues in evaluation of an adolescent who presented with severe hyperkalemia and acute kidney injury that was resistant to insulin, glucose, and sodium polystyrene sulfonate and was found to have primary adrenal insufficiency.

Addison disease is chronic primary adrenal insufficiency, which, in developed countries, is most commonly due to autoimmune destruction of the cortex (termed autoimmune or idiopathic Addison disease). Although the disease process has some classic features, such as increased pigmentation, salt craving, and signs and symptoms related to decreased blood pressure, the initial clinical presentation may be vague and/or insidious. Following an acute stressor such as a gastrointestinal (GI) infection, the patient may experience an adrenal crisis, which can cause sudden death. As such, knowledge of this disease process and the diagnostic criteria in the postmortem period is essential for the practicing forensic pathologist. The diagnosis of autoimmune Addison disease at autopsy is aided by several factors including 1) history, including salt craving, features consistent with orthostatic hypotension, and GI complaints including nausea, vomiting and pain, 2) physical examination findings of increased pigmentation and small or unidentifiable adrenal glands, 3) serologic testing for 21-hydroxylase antibodies, 4) serum cortisol concentrations, and 5) vitreous electrolyte testing. While the listed historical information, the increased pigmentation, decreased serum cortisol concentrations, and evidence of hyponatremia may be found in all forms of Addison disease, small or unidentifiable adrenal glands and 21-hydroxylase antibodies are found exclusively in the autoimmune form of Addison disease. While other causes of Addison disease, such as tuberculosis, metastatic tumor, or other infiltrative processes would have enlarged adrenal glands, these diseases would lack 21-hydroxylase antibodies. The purpose of this paper is to focus on the diagnosis of autoimmune Addison disease.
