RESUMO
Gastrointestinal carcinoid tumors represent a group of well-differentiated tumors originating from various neuroendocrine cells located in the gastrointestinal mucosa and submucosa. Consequently, there is diversity in their clinical presentation, incidence at specific anatomic sites, biological behavior, hormone production, morphologic characteristics, and immunophenotype. Periampullary carcinoids are extremely rare and less then 100 patients have been reported in the world literature, that too mostly as case reports. We are reporting two cases of periampullary carcinoids, one of which presented with rare manifestation as gastrointestinal bleed and both are doing well after successful pancreatoduodenectomy.

Secretory immunoglobulin A (S-IgA), coproantibody titre (antiamoebic) and IgA, IgG, IgM immunocytes in rectal mucosa were studied in 13 patients with amoebic liver abscess (ALA) prior to and 4-6 weeks after completion of antiamoebic therapy. Ten asymptomatic Entamoeba histolytica cyst passers and 17 healthy age and sex matched volunteers served as controls. Fecal S-IgA levels and counts of IgA bearing immunocytes in mucosa were significantly higher in patients with ALA and cyst passers as compared to healthy controls and showed a significant fall after treatment. Fecal antiamoebic antibodies were high in cyst passers and in cases of ALA after treatment. Raised levels of S-IgA and IgA class immunocyte counts probably indicate a local mucosal immune response directed at containing the infection.
