Adenoma velloso de apéndice. Actitud diagnóstica y terapéutica / Villous adenoma of the appendix. Diagnostic and therapeutic approach

El adenoma velloso de apéndice es una entidad patológica rara que adopta formas de presentación clínica que difieren de la de los adenomas vellosos en otras localizaciones del tubo digestivo. Pacientes y métodos: hemos revisado los casos de adenoma velloso apendicular que se han diagnosticado en nuestro hospital en un periodo de tiempo de cinco años. Se estudia la distribución por edades, sexo, las formas de presentación clínica, los métodos diagnósticos empleados, el tratamiento efectuado y el seguimiento realizado. Resultados: se han diagnosticado un total de seis casos de adenoma velloso apendicular siendo la forma de presentación clínica más habitual la apendicitis aguda. Los tratamientos aplicados fueron apendicectomía en 2 casos, hemicolectomía derecha en 2 pacientes, colectomía subtotal en un paciente y Hartmann más apendicectomía en otro caso. Conclusiones: consideramos que la apendicectomía será el tratamiento de elección siempre que no haya degeneración maligna del adenoma y que este no invada el borde de resección quirúrgica (AU)

Villous adenoma of the appendix. Diagnostic and therapeutic approach.

UNLABELLED: Appendix villous adenoma is a rare pathological entity that shows a particular form of clinical presentation that is different from villous adenomas in other places along the gastrointestinal tract. PATIENTS AND METHODS: We reviewed cases of appendix villous adenoma diagnosed in our hospital during the last five years; we studied age, distribution, sex, clinical presentation, diagnostic methods used, treatment and follow-up of patients. RESULTS: We diagnosed 6 cases of villous adenoma of the appendix, acute appendicitis being the most common form of clinical presentation. Treatment was appendectomy in two cases, right hemicolectomy in two patients, subtotal colectomy in one case, and Hartmann's technique with appendectomy in one more case. CONCLUSIONS: We consider appendectomy the treatment of choice when no malignant degeneration is present in the adenoma and invasion of surgical resection borders is absent.

Giant-cell tumor in soft parts in a patient with osseous Paget's disease: diagnosis by fine-needle aspiration.

In this report, the cytological features and differential diagnosis of a case of giant-cell tumor (GCT) in soft tissues in a patient with osseous Paget's disease (PD) are described, with histological confirmation. Characteristic cytological findings include a diffuse cellular population of neoplastic cells composed of two types: one group of polygonal or round mononuclear small cells, exhibiting a thin-rim, dense cytoplasm and single hyperchromatic nuclei; and the second group of multinucleated, osteoclast-type giant cells with dozens of round nuclei, showing occasional micronucleoli. A prominent feature is the presence of numerous capillary structures surrounded by tumor cells. The differential diagnosis includes a number of other neoplastic and reactive processes in which giant cells may be abundant. The cytological features of GCT appear to be characteristic enough to allow a suggestive diagnosis. However, the final diagnosis should be made only after the lesion has been studied histologically.

[Villous adenoma of the appendix caused acute appendicitis]. / Adenoma velloso de apéndice causante de apendicitis aguda.

Villous adenoma of the appendix is a rare pathologic entity, the treatment is controversial. We describe the case of a patient complaining of abdominal pain that was diagnosed as acute appendicitis. Pathological examination of the surgical specimen revealed a villous adenoma of the appendix. We comment the therapeutic options and we review the literature about this pathological entity.
