Clinical and pathological features of gastrointestinal stromal tumors (GIST) in a single institution: A descriptive study and review of the literature.

Introduction: This study was aimed to assess the main clinical, pathological and therapeutic characteristics of a cohort of gastrointestinal stromal tumors (GIST).

Methods: Observational study including 66 patients diagnosed with GIST admitted to our hospital between 2002 and 2015. Parameters related to medical history, clinical manifestations, medical and surgical treatment, histopathology, and morbi-mortality were studied.

Diffuse pulmonary meningotheliomatosis diagnosed by transbronchial lung biopsy.

Minute pulmonary meningothelial-like nodules (MPMNs) are usually unique lesions in the lung parenchyma.

MPMNs are mainly asymptomatic and are diagnosed after lung surgery or during autopsy.

[Utility of frozen section in the surgical treatment of thyroid nodules].

Objective: To present our experience of the use of frozen section (FS) in the operative management of thyroid nodules and determine the utility of this procedure when deciding the extent of thyroidectomy.

Patients And Method: We performed a prospective and comparative study. The FS of patients who underwent surgery for thyroid nodules between 1995 and 2002 were evaluated.

[Gastrointestinal stromal tumors. Diagnosis, prognosis and current surgical treatment. Follow-up of 18 treated patients].

Introduction: Gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal tumors of the digestive tract and their growth is directed through the signaling of the KIT or PDFGRA genes. The objective of the present study was to describe a series of cases of GIST tumors located in the stomach.

Patients And Methods: We performed a retrospective, descriptive study of 18 patients diagnosed with gastric GIST and treated by means of gastric resection between July 1996 and June 2004.
