Lupus as a paraneoplastic manifestation of cholangiocarcinoma.

Tumors originating in the digestive system, like those in other areas, whether solid or otherwise, may present with extradigestive manifestations in the setting of a paraneoplastic syndrome. Systemic lupus erythematosus (SLE) is an autoimmune condition most commonly involving women of childbearing age. On occasion it represents a paraneoplastic manifestation heralding a primary tumor. Cancer suspicion is therefore a key element for newly diagnosed SLE cases with nonstandard epidemiology even in the absence of suggestive symptoms, and digestive tumors should be included in the differential diagnosis.

Direct parasitologial diagnosis of infection with Hysterothylacium aduncum in a patient with epigastralgia.

Anisakis parasitization has been on the rise because some factors, like increased interest in dishes consisting of raw fish. We report a case of epigastralgia with direct diagnosis by endoscopy, which futher study pointed out H. Aduncum as causal agent, a anisakis which is rarely involved in human anisakiasis.
