The correlation between TTF-1 immunoreactivity and the occurrence of lymph node metastases in patients with lung cancer.

Aims And Background: Thyroid transcription factor (TTF-1) is a tissue-specific transcription factor expressed in the epithelial cells of thyroid and lung. The aim of this study was to evaluate the relationship between the expression of TTF-1 and clinico-pathological parameters in pulmonary adenocarcinoma and adenosquamous carcinoma.

Methods: Resection material of pneumonectomies and lobectomies of 39 patients was retrospectively examined.

A patient with ankylosing spondylitis who presented with chronic necrotising aspergillosis: report on one case and review of the literature.

Upper lobe fibrobullous disease is a well-known finding in advanced stages of ankylosing spondylitis (AS). In this report, we present a 57-year-old male patient who was diagnosed with a right apical cavitary lesion after coming to us with the complaint of haemoptysis. The patient underwent upper lobe segmentectomy and an aspergilloma was detected.
