Inflammatory pseudotumor and myofibroblastic inflammatory tumor. Diagnostic criteria and prognostic differences.

Introduction: Inflammatory pseudotumor (IPT) and inflammatory myofibroblastic tumor (IMT) are two very rare entities that were formerly included in the same category; however, today they are considered two different diseases due to the neoplastic origin of the IMT. Our objective is to share our experience in the management of these two types of tumors that we must take into account in the differential diagnosis of pulmonary masses or nodules.

Methods: Thirteen patients with a pathological diagnosis of IPT and IMT who underwent surgery between 2008 and 2019 were retrospectively studied.

Prognostic significance of histopathological factors in survival and recurrence of atypical carcinoid tumours.

Objectives: Atypical carcinoids are neuroendocrine neoplasms of intermediate degree and low frequency. The aim of this study is to analyse their clinical characteristics and the importance of different histopathological factors in their prognosis.

Methods: Multicentre cooperative group EMETNE prospectively reviewed 153 patients operated on between 1998 and 2016 with diagnosis of atypical carcinoids.

Enzymatic mediastinitis as a fearsome complication of pancreatic necrosectomy.

Several types of thoracic complications can be associated with severe acute pancreatitis. Some are very common, such as pleural effusion, whilst some others are very rare although life threatening, such as enzymatic mediastinitis (EM). Only a few cases of EM (when related to acute pancreatitis) have been described in the literature.

Is age a predisposing factor of postoperative complications after lung resection for primary pulmonary neoplasms?

Introduction: Age has been classically considered as a determining factor for the development of postoperative complications related to lung resection for bronchogenic carcinoma. The Postoperative Complications Study Group of the Spanish Society of Thoracic Surgery has promoted a registry to analyze this factor.

Methods: A total of 3,307 patients who underwent any type of surgical resection for bronchogenic carcinoma have been systematically and prospectively recorded in any of the 24 units that are part of the group.

Primary pulmonary synovial sarcoma: a rare neoplasm.

Primary pulmonary synovial sarcoma is an extremely rare tumor with an unknown cause. The diagnosis is established after other primary lung malignancies or metastatic extrathoracic sarcoma have been excluded. We report the case of a 69-year-old man who presented with a well-defined mass in the right upper lobe on a chest X-ray.

Giant thymolipoma: case report of an unusual mediastinal tumor.

Thymolipoma is an uncommon benign neoplasm of the thymus composed of mature adipose and thymic tissue. The diagnosis of thymolipoma should be considered in the case of a mediastinal mass with fat density, especially if it is interspersed with strands of soft tissue attenuation on computed tomography scans. However, it is sometimes difficult to differentiate radiologically between a thymolipoma and other mediastinal fatty tumors.

Thoracic liposarcoma: resection and chest wall reconstruction.

Liposarcoma is a malignant neoplasm of mesodermal origin derived from adipose tissue. It most often originates in the extremities and retroperitoneum, and less frequently in the head and neck. Liposarcoma involving the chest wall is extremely rare with few reported cases.

Primary pulmonary angiosarcoma, an exceptional neoplasm with a poor prognosis: reports of two cases and review of the literature.

Primary pulmonary angiosarcoma is a rare type of malignant vascular tumour characterised by proliferation of tumour cells with endothelial features. Up to date, only sixteen cases have been reported in English Literature. Treatment modalities vary from none to surgery, chemotherapeutic regimens, radiotherapy or immunotherapy, but none of them have been shown to be effective.

[Influence of delay of surgery on the survival of patients with bronchogenic carcinoma].

Objective: Bronchogenic carcinoma is the main cause of tumor-related deaths among men in Spain. The British Thoracic Society recommends that no longer than 4 weeks should pass from the moment a patient s name is placed on a waiting list until surgery takes place. We analyzed the influence of time until surgery on survival in patients with lung cancer.
