Pulmonary T-cell lymphoma masquerading as eosinophilic pneumonitis.

Primary pulmonary T-cell lymphoma is an unusual subtype of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). This is a general term used to describe a diverse group of T-cell-type lymphomas that would otherwise not be classified as a PTCL. Among non-Hodgkin's lymphomas, PTCL accounts for 12% of cases.

State-of-the-Art Modalities for Peripheral Lung Nodule Biopsy.

Lung nodules are being increasingly detected, particularly with lung cancer screening with low-dose computed tomography. Although the vast majority of lung nodules are benign, many often require tissue diagnosis. Several modalities to obtain diagnostic tissue from peripheral lung nodules are available.

Comparison of in vivo probe-based confocal laser endomicroscopy with histopathology in lung cancer: A move toward optical biopsy.

Background And Objective: The development of novel technologies has increased the yield from transbronchial biopsies while preserving patient safety by guiding biopsies to the area of interest. Other technologies have helped identify pre-cancerous or sessile lesions in the endobronchial space by utilizing interactions between tissue and light at varying wavelengths. Probe-based confocal laser endomicroscopy (pCLE) is a new technology that encompasses the benefits of both guided biopsies and novel optical imaging in one device.
