A case report: asymptomatic esophageal eosinophilia after herpes simplex esophagitis. Controversies in the therapeutic approach.

The coexistence of eosinophilic esophagitis and herpes simplex virus in patients has been published in numerous case reports in the last few years. Both entities can be diagnosed simultaneously or one prior to the other, raising a possible causal relationship. Esophageal eosinophilia is a histological finding, and its underlying cause should be investigated.

[Pituitary metastases in patients with prior neoplasms].

The pituitary is an uncommon site for metastases. We report three cases of patients with a history of cancer (breast and lung) who presented with symptoms of headache, ophthalmoplegia, fatigue, diabetes insipidus, nausea, and vomiting. Cranial magnetic resonance imaging was performed, revealing sellar masses with infiltration of the adjacent tissues compatible with pituitary metastases in all three patients.
