Synchronous Two Distinct Neuroendocrine Lung Cancer Lesions
2015
Synchroniczne nowotwory płuc są rzadką chorobą, a prezentowany przypadek to pierwszy opublikowany opis jednoczesnego wystąpienia dwóch pierwotnych neuroendokrynnych raków płuca zlokalizowanych w jednym płacie. Przedstawiono przypadek 55-letniej pacjentki z dwoma pierwotnymi, odrębnymi neuroendokrynnymi rakami płata górnego płuca prawego. Pacjentka została przyjęta na oddział chirurgii klatki piersiowej w celu diagnostyki dwóch cieni okrągłych płuca prawego (o średnicy 11 i 19 mm) uwidocznionych na zdjęciu RTG klatki piersiowej wykonanym trzy miesiące wcześniej. Przy przyjęciu pacjentka nie prezentowała żadnych objawów związanych ze zmianami w płucu. Dalsze badania obrazowe wykazały zmiennoś…
Successful surgery of neuroendocrine carcinoma infiltrating right ventricle and pulmonary artery.
2020
We present the clinical case of a 60-year-old woman complained of dyspnea on exertion. Echocardiogram showed a giant mass in the right ventricle (RV) with obstruction to the outflow tract. Thorax computed tomography confirmed a mass of greater than 60 mm infiltrating RV and causing severe stenosis in the pulmonary artery, with severe pericardial effusion. Cardiac surgery was performed for tumor resection and pulmonary root replacement with a biological valved conduit. Histological analysis diagnosed a poorly differentiated large-cell neuroendocrine carcinoma. The patient had no immediate postoperative complications and has completed radiotherapy at a 9-month follow-up.
The association between appendicitis severity and patient age with appendiceal neoplasm histology—a population-based study
2022
Abstract Purpose Recent studies have reported alarming appendiceal tumor rates associated with complicated acute appendicitis, especially in patients presenting with a periappendicular abscess. However, the data on histology of appendiceal tumors among acute appendicitis patients is limited, especially in patient cohorts differentiating between uncomplicated and complicated acute appendicitis. We have previously reported the association of increased appendiceal tumor prevalence with complicated acute appendicitis in this population-based study. The objective of this secondary analysis was to evaluate the association of both appendicitis severity and patient age with appendiceal tumor histol…
"Pure" large cell neuroendocrine carcinoma of the gallbladder. Report of a case and review of the literature
2016
Primary Neuroendocrine Tumours (NETs) of the gallbladder are rare. Among all NETs of the gallbladder, large cell neuroendocrine carcinoma (LCNEC) is exceedingly rare. In most of the cases LCNECs are combined with other histological components. We reviewed clinical presentation and management of all patients with "pure" LCNEC from published literature since the first case was published in 2000, as well as one patient from our experience. Only 7 cases of "pure" LCNEC has been described in the last 15 years, our case is the eighth. The diagnosis of gallbladder NETs is rarely made preoperatively since the presentation generally consists of non-specific symptoms including upper abdominal pain, d…
