Endoscopy as a diagnostic and therapeutic alternative technique of taeniasis.

Despite a low incidence in developed countries, gastrointestinal taeniasis should be suspected in patients with abdominal pain, diarrhea, anemia, and/or malabsorption of unknown origin, even more so if they come from endemic regions or areas with poor hygienic and alimentary habits. Diagnosis is traditionally reached by identifying the parasite in stools, but more recently both serological and immunological approaches are also available. Based on a patient diagnosed by gastroscopy, a literature review was undertaken of patients diagnosed by endoscopy.

Malignant nodular hidradenoma on the scalp: report of a case with fine needle aspiration cytology features and histologic correlation.

Background: Malignant nodular hidradenoma (MNH) is a malignant adnexal tumor of the eccrine sweat glands. The histology is similar to that of benign nodular hidradenoma, but MNH shows an infiltrative and invasive pattern, necrosis and angiolymphatic invasion.

Case: A 60-year-old woman, diagnosed with rectal adenocarcinoma 6 months before, underwent fine needle aspiration (FNA) of a nodule on the scalp.

Primary monophasic synovial sarcoma of the duodenum confirmed by cytogenetic analysis with demonstration of t(X;18): a case report.

Synovial sarcoma (SS) is an uncommon malignant neoplasm of the soft tissues. It mainly affects the periarticular tissues of the extremities in young adults, but has been described at nearly all sites; nevertheless, the gastrointestinal tract is an exceptional location. We report a case of a primary synovial sarcoma of the duodenum in a 69-year-old woman.

Cardiac papillary fibroelastoma in left ventricular apex.

Papillary fibroelastoma (PF) is a rare benign heart tumor and represents less than 10% of primary cardiac tumors. It mainly affects the cardiac valves and is often discovered during open heart surgery or autopsy. We present a case of a patient who was detected with a left ventricular apex tumor during the evaluation of the transient ischemic attack.
