Symptomatic gastrointestinal amyloidosis in an HIV-infected patient.

We report a rare case of symptomatic GI amyloidosis in an HIV-infected patient who ultimately developed uncontrollable upper GI bleeding. Gastric and jejunal biopsies revealed amyloidosis. Although the patient's history suggested the possibility of secondary amyloidosis, immunohistochemical staining together with serum electrophoresis and immunofixation revealed the presence of lambda light chains indicating primary amyloidosis.

Gastrointestinal manifestations of amyloidosis: a case of diverticular perforation.

Amyloidosis is an intriguing disorder. Its clinical presentation usually rests on the organ(s) infiltrated with the amyloid. We report a patient who presented with peritonitis secondary to a perforated large jejunal diverticulum and multiple small bowel diverticula.

Esophageal involvement by cutaneous T-cell lymphoma, mycosis fungoides type: diagnosis by endoscopic biopsy.

A patient with long-standing cutaneous T-cell lymphoma, mycosis fungoides type (CTCL-MF), developed dysphagia, odynophagia, and weight loss. Endoscopic biopsy of esophageal mucosa demonstrated involvement by CTCL-MF. Although extracutaneous spread of CTCL-MF is common, esophageal involvement is unusual and to our knowledge has not previously been diagnosed antemortem.

Multiple granular cell tumors of the bronchi: treatment with laser.

Granular cell tumors involving multiple bronchial and extrapulmonary sites were found in a young man. Carbon dioxide laser ray was applied through a specially fitted rigid bronchoscope to a lesion at the left mainstem bronchus. Serial follow-up bronchoscopies revealed a white scarred plaque without evidence of regrowth.

Hypoglycemic coma associated with benign pleural mesothelioma.

A case of hypoglycemic coma and benign pleural mesothelioma is described. Serum insulin levels, as measured by insulin radioimmunoassay, were appropriately suppressed and consistent with hypoglycemia. Assay of the tumor showed insulin to be undectable.
