Tumor neuroendocrino, mucocele y adenoma tubulo-velloso: tres lesiones infrecuentes en el apéndice cecal / Neuroendocrine tumours, mucocele, and tubulovillous adenoma: three uncommon lesions in the cecal appendix

Introducción: los tumores del apéndice cecal constituyen un grupo heterogéneo de neoplasias con evolución y pronóstico variables; representan una pequeña parte de todas las neoplasias gastrointestinales y de las apendicetomías. Objetivo: realizar la comunicación de la presentación de tumores infrecuentes del apéndice cecal y revisar la literatura con énfasis la importancia del diagnóstico histopa-tológico. Presentación de caso: durante la necropsia del paciente HC: 199584 se realizó el diagnóstico histopatológico de un tumor neuroendocrino y mucocele apendicular y en la pieza quirúrgica del paciente HC: 223360 correspondiente a una apendicectomía se realizó el diagnóstico de adenoma tubulo-velloso, dadas que estas lesiones son poco frecuente se decide su comunicación y la revisión del tema en la literatura en idioma inglés y español a través de las bases de datos MEDLINE/PubMed, Elsevier, SciELO, EBSCO, Hinari y búsqueda avanzada en Google Scholar, encontrándose un total de 29 publicaciones entre 1990 a 2019. Conclusiones: el diagnóstico de tumores del apéndice cecal se realiza en forma incidental en el estudio anatomopatológico después de una apendicectomía por apendicitis aguda, es por ello que siempre se debe realizar el estudio histológico de la pieza quirúrgica, no solo para confirmar o negar el diagnostico que motivo la apendicetomía, sino para descartar la presencia de lesiones neoplásicas benignas o malignas.

Introduction: Tumors of the cecal appendix constitute a heterogeneous group of neoplasms with variable evolution and prognosis; they represent a small part of all gastrointestinal neoplasms and appendectomies. Objective: To communicate the presentation of infrequent tumours of the cecal appendix and to review the literature with emphasis on the importance of histopathological diagnosis. Case presentation: During the necropsy of patient HC: 199584, a histopathological diagnosis of carcinoid tumours and appendicular mucocele was made, and in the surgical specimen of patient HC: 223360 correspondings to an appendectomy, the diagnosis of tubu-lovillous adenoma were made, given that These lesions are rare, it is decided to communicate and review the subject in the literature in English and Spanish through the MEDLINE / PubMed, Elsevier, SciELO, EBSCO, Hinari and Advanced Search in Google Scholar data-bases, finding a total of 29 publications between 1990 to 2019. Conclusions: The diagnosis of tumours of the cecal appendix is made incidentally in the pathological study after an appendectomy for acute appendicitis, which is why the histological study of the surgical piece should always be carried out, not only to confirm or deny the diagnosis. What reason for the appendectomy but to rule out the presence of benign or malignant neoplastic lesions.

Misdiagnosed Case of Bronchial Carcinoid Presenting with Refractory Dyspnoea and Wheeze: A Rare Case Report and Review of Literature

A 59-year-old male smoker presented with persistent wheezing and occasional coughing that had been ongoing for two years and had been unsuccessfully treated with an inhalational β2 agonist, an anticholinergic and an inhalational steroid in the last year. On clinical examination, a left-sided wheeze was detected. The initial chest X-ray was normal. A computed tomography (CT) scan of thorax demonstrated a mass lesion in the left main bronchus. On subsequent bronchoscopy, an endobronchial polypoid mass was detected in the left main bronchus, completely occluding the bronchial lumen. A biopsy taken from the mass revealed features of bronchial carcinoid. Bronchial carcinoid can present uncommonly with wheezes, resulting in misdiagnosis as bronchial asthma or chronic obstructive pulmonary disease (COPD). If an asthma or COPD patient does not respond to conventional therapy, a CT scan and subsequent bronchoscopy is warranted.
