ABSTRACT
La neoplasia papilar intracolecística (NPIC), es un tumor compuesto por células neoplásicas preinvasivas, que forman masas de hasta 1,0 cm, clínicamente detectables. El objetivo de este estudio fue reportar un caso de NPIC y revisar la evidencia existente. Se trata de un paciente sexo masculino, de 33 años de edad, asintomático, que en el curso de un examen de salud, se realiza una ecotomografía abdominal, en la que se verifica una lesión polipoide vesicular de 32 x 19 mm de diámetro. Se programa para colecistectomía electiva, la que se realizó por vía laparoscópica, cirugía que se pudo realizar sin inconvenientes. Una vez extirpado el espécimen, se fue a estudio histopatológico en el que tras un mapeo vesicular se concluye NPIC, colecistitis crónica inespecífica, colesterolosis y pólipos colesterínicos. El paciente ha evolucionado sin inconvenientes. Presentamos un caso de NPIC en un paciente joven, cuyo diagnóstico fue confirmado por anatomía patológica tras una colecistectomía electiva, descartándose la presencia de carcinoma invasivo y displasia de alto grado, por lo que el pronóstico es favorable.
Intracholecystic papillary neoplasm (ICPN) is a tumor composed of pre-invasive neoplastic cells, with up to 1.0 cm clinically detectable masses. The objective of this study was to report a case of NPIC and review the evidence in the literature. A 33-year-old asymptomatic male patient had an abdominal ultrasonography during a health examination, in which a vesicular polyp lesion of 32 x 19 mm in diameter was verified. Thepatient was subsequently scheduled for elective cholecystectomy, which was performed laparoscopically and the surgery was uneventful. Once removed, the specimen was studied histopathologically and after performing vesicular mapping, we determined an ICPN, chronic non-specific cholecystitis, cholesteroliasis and cholesteric polyps. The patient has evolved without reported problems. We present a case of ICPN in a young patient, whose diagnosis was confirmed by pathological anatomy after an elective cholecystectomy, ruling out the presence of invasive carcinoma and high-grade dysplasia, with a favorable prognosis.

A series of 241 polyps from 127 patients endoscopically removed during the period from march 1991 through July 1992 at our department were analysed. The following items were studied. 1) Incidence, age, and sex distrlbution of the patients 2) Number of the calonic polyps 3) Histologic classification and polyp size 4) Anatomic distribution and polyp size 5) Gross types and polyp size 6) Hietopathologic types and polyp size In conclusion, colonic diminutive polyps should not be ignored or overlooked clinically. The majority were neoplastic polyps. It is suggested that diminutive polyps should be removed endoscopically if possible
