Appendiceal diverticulitis and acute appendicitis: differences and similarities.

Introduction: Acute appendiceal diverticulitis is an unusual cause of acute abdomen, considered clinically indistinguishable from acute appendicitis.

Material And Methods: In a historic cohort study with 27 cases of appendiceal diverticulitis and 54 cases of acute appendicitis, we compared clinical characteristics, diagnostic tests and pathology findings of the two processes.

Results: Mean age at presentation was lower in acute appendicitis (37.

Linitis-like squamous esophageal cancer diagnosed by endoscopic ultrasonography-guided fine-needle aspiration cytology: report of two cases.

Endoscopic ultrasonography-guided fine-needle aspiration cytology (EUS-FNA) may provide full-thickness biopsies, adequate for cytology and histology. In the present case report, we describe the first cases of a rare well-differentiated squamous esophageal carcinoma (verrucous esophageal cancer), finally diagnosed by EUS-FNA using a large FNA needle after several upper endoscopies with biopsies negative for malignancy. In this report, we highlight the usefulness of this procedure and EUS features in the diagnosis of suspicious esophageal lesions with negative endoscopic biopsies for malignancy.
