Congenital esophageal stenosis in adults.

Objective: Congenital esophageal stenosis is thought to be a rare disease confined to infancy and childhood with only a few case reports in adults described.

Methods: We report five patients between the ages of 19 and 46 yr who presented with this disorder over a 2-yr period.

Results: Patients had been labeled with reflux strictures, webs, or as idiopathic in the past.

Gastric small lymphocytic proliferation with immunoglobulin gene rearrangement in pseudolymphoma versus lymphoma.

The nature of gastric infiltrates consisting primarily of benign-appearing small lymphocytes is at present a controversial issue. Earlier reports of gastric lymphoma developing in gastric pseudolymphoma and more recent immunohistochemical studies demonstrating monoclonal B-cell populations in pseudolymphoma suggest that at least some cases represent low-grade lymphomas or clonal precursor lesions that may develop into lymphoma. Observations of a small lymphocytic infiltrate arising in the region of a gastric ulcer that lacked definitive morphologic evidence of malignancy (lymphoma) but was clearly a monoclonal B-cell proliferation by immunohistochemical and gene rearrangement studies support the notion that some gastric lymphoproliferative lesions that histologically have been called pseudolymphomas may include one or more clonal lymphoid expansions.

Osteomalacia as a very late manifestation of primary hyperparathyroidism.

An 86-year-old woman with a history of treated hyperthyroidism and a 20-year history of untreated primary hyperparathyroidism developed generalized bone pain and a pseudofracture of the midshaft of the left femur. Laboratory examinations revealed elevated serum calcium, alkaline phosphatase, and C-terminal parathyroid hormone levels. Serum inorganic phosphate was below normal and 25-hydroxyvitamin D levels were low-normal.

Milk of calcium bile. Evidence that gallbladder stasis is a key factor.

Milk of calcium bile is a rare disorder in which the gallbladder lumen is filled with a semisolid radiopaque material composed primarily of calcium carbonate. The etiology is unknown, although gallbladder stasis is believed to be a prerequisite. We report a case of milk of calcium bile in which preexisting gallbladder stasis was retrospectively evaluated by reviewing plain abdominal films and by using iodide as a marker for retained contrast.
