Pituitary gland metastases are very rare. Most patients with pituitary gland metastases are asymptomatic; therefore, most cases of this disease are diagnosed during autopsies. Moreover, the four most common primary tumors that metastasize to the pituitary gland are breast, lung, thyroid, and renal carcinomas. We present a very rare case of pituitary metastasis of spindle cell rhabdomyosarcoma (RMS). Our patient presented with headache, visual disorder, panhypopituitarism, and diabetes insipidus. Due to tumor expansion, resection was not possible, so diagnosis was confirmed by biopsy, and chemotherapy and irradiation were administered. Our patient showed widespread spindle cell RMS, which harbors a mutation of myogenic differentiation 1 (MYOD1) and is associated with a poor prognosis. Even high-risk patients can show a remission after chemotherapy and irradiation. In the cases with indistinct lesions in the sella region, pituitary metastasis should always be considered.

Isolated ectopic secretion of corticotropin-releasing hormone (CRH) is an exceedingly rare cause of Cushing's syndrome (CS), accounting for fewer than 1% of cases. Ectopic CS is an uncommon but potentially life-threatening condition that often necessitates urgent diagnostic evaluation and treatment. Hormonal testing may suggest a pituitary origin, complicating the diagnostic process.

Lung cancer is the leading cause of cancer and cancer-related deaths, and India ranks the fourth highest country. Lung cancer is a highly aggressive malignancy with a tendency for rapid progression, making early detection and prompt treatment essential for improving patient outcomes. Lung cancer can spread locally into surrounding tissue as well as travel through lymphatics to other parts of the body, most often to bone, brain, liver, and adrenal glands.

Inborn errors of immunity (IEI) presenting with immunodeficiency and autoimmunity can illuminate pathways essential for immunocompetence and self-tolerance. We recently characterized a new IEI named MAGIS ("idline malformations of the brain, nterior pituitary gland dysfunction, rowth retardation, mmunodysregulation/immunodeficiency, and keletal defects") caused by heterozygous germline activating mutations in (encoding the heterotrimeric G-protein, G). This disorder demonstrates the central role of G regulation of chemotaxis in humans and a novel pathway by which G-proteins regulate T-cell activation.

Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis (MS). The latter is a human organ-specific autoimmune disease of the central nervous system (CNS). EAE is characterized by systemic inflammation associated with increased blood levels of proinflammatory mediators that potentially trigger inflammation of both reproductive organs and the CNS.

The low dose dexamethasone stimulation test (LDDST) is routinely used in canine medicine but in the few cases in guinea pigs diagnosed with hypercortisolism, the adrenocorticotropic hormone (ACTH) stimulation test was used. The objective of the authors was to conduct a pilot study and find out if the standard test used in dogs can be used in this species.A 4-year-old intact female hairless guinea pig showed bilaterally enlarged adrenal glands and high cortisol levels.
