RESUMEN
A 2-year-old amerasian male with anhidrotic ectodermal dysplasia (Christ-Siemens-Touraine Syndrome) was admitted for status epilepticus and Mycobacteria avium-intracellulare infection. A computed tomography scan of the head revealed a mass thought to be a subdural hematoma. The patient died following overwhelming Mycobacteria avium-intracellular and Pseudomonas aeruginosa sepsis. Autopsy revealed extensive extramedullary hematopoiesis of the dura forming a tumor-like thickening with focal subdural hemorrhage. To our knowledge, this is the first report of extramedullary hematopoiesis of the cranial dura associated with anhidrotic ectodermal dysplasia.

An intracranial mass thought clinically and by computed tomography and angiography to be a meningioma proved to be an inflammatory pseudotumor. The lesion was composed of sheets of mature plasma cells and lymphocytes with germinal center formation. Immunohistochemical studies revealed a polyclonal cell population, supporting a diagnosis of a reactive lesion rather than a plasma cell neoplasm. Inflammatory pseudotumor should be considered in the differential diagnosis of a sharply demarcated intracranial mass clinically and radiologically diagnosed as meningioma.

Esophageal ulcers associated with acquired immunodeficiency syndrome (AIDS) may be chronic, debilitating, and resistant to antifungal or antiviral therapy. The therapeutic management of these lesions remains controversial due to the difficulty in identifying pathogenic agent(s). We review previously published cases and describe three AIDS patients with esophageal ulcers that stained by immunoperoxidase techniques for human immunodeficiency virus (HIV)-1 surface glyloprotein (gp41). All three showed symptomatic resolution and healing of their ulcers with corticosteroid therapy. We believe this documentation of HIV-1 gp41 antigen within mononuclear cells of esophageal ulcers in AIDS supports a role of the HIV-1 virus in the pathophysiology of idiopathic esophageal ulcers in patients with AIDS. These cases further support a role for corticosteroid therapy in the treatment of esophageal ulcers resistant to antifungal and antiviral therapy in patients with AIDS.

A 70-year-old former shipyard worker presented with dyspnea and edema of the upper thorax suggesting the diagnosis of superior vena cava syndrome. Further evaluation revealed mesothelioma with both epithelial and spindled histologic patterns. The extensive mesothelioma had invaded the adventitia of the superior vena cava, the pleura of the lungs bilaterally, the superficial myocardium, and the liver. A terminal hyercoagulable state with great vein thrombosis was also contributory. To our knowledge this is the first documented case of superior vena cava syndrome associated with malignant mesothelioma.

A pigmented choroid plexus papilloma was found in the left lateral ventricle of a 15-year-old white boy with a 10-year history of seizures. Grossly the lesion appeared finely lobular, orangish brown, rubbery, gritty, and friable. Microscopic examination revealed delicate papillary formations reminiscent of normal choroid plexus, with simple cuboidal to columnar epithelium overlying fibrovascular cores. Light- and electron-microscopic studies demonstrated that the neoplastic cell pigment consisted of both neuromelanin and lipofuscin. To our knowledge, this is the first reported case of neuromelanin pigmentation within a choroid plexus papilloma.
