The aim of the present study was to investigate the value of Ca 125, a tumour marker, in evaluation of pulmonary tuberculosis activity. This study included 96 subjects who were divided into three groups. Group 1 consisted of 40 patients with active pulmonary tuberculosis. Group 2 included 20 patients with inactive pulmonary tuberculosis. There were 36 healthy subjects in group 3. While measurement of serum Ca 125 level was performed only once in groups 2 and 3, Ca 125 levels were measured five times in group 1. The measurements were performed before the treatment, at the second, fourth and sixth months and the third year following the end of the treatment. Mean +/- SD serum Ca 125 concentrations were 109.7 +/- 86.9 U ml(-1) in group 1, 14.5 +/- 7.8 U ml(-1) in group 2 and 10.5 +/- 7.3 U ml(-1) in group 3. Serum Ca 125 levels were significantly higher in group 1 than in the other groups (P < 0.0001), but there was no significant statistical difference between the values of groups 2 and 3 (P > 0.05). Ca 125 levels in group 1 showed a significant decrease after treatment (P < 0.0001). For estimation of the activity of tuberculosis, the sensitivity and specificity of Ca 125 were found 97.5% and 100%, respectively at a 31 U ml(-1) cut-off point. Our results suggest that Ca 125 is beneficial in the determinaton of tuberculosis activity and in differentiation between active and inactive pulmonary tuberculosis.
Pulmonary glomus tumours are rare lesions, with few cases reported previously. Herein, we present the clinical and pathological features of a case of pulmonary glomus tumour. A 29-year-old female patient presented to our clinic complaining of cough, dyspnoea and left-sided chest pain. Computed tomography (CT) of the thorax revealed a nodular lesion causing obstruction of the left main bronchus. Fibreoptic bronchoscopy demonstrated a polypoid mass occluding the left main bronchus 10 mm distal to the main carina. Bronchoscopic biopsy was interpreted histologically as carcinoid tumour. Bronchotomy plus mass extirpation was performed with left thoracotomy. Microscopically, a tumoral structure composed of uniform cells with a round centrally located nucleolus and narrow eosinophilic cytoplasm was seen. Thin-walled vessels lined with endothelium were interspersed between tumoral structures. The cells were stained chromogranin and cytokeratin negative and strongly vimentin positive. The pathological diagnosis for the thoracotomy specimen was pulmonary glomus tumour. Follow-up chest CT was negative for recurrent tumour and the patient remains free of disease 17 months after surgery.
The most commonly encountered radiological finding in sarcoidosis is bilateral hilar lymph node enlargement. Cavitation is extremely rare and the acute cavitary form is seen infrequently in young adults with acinar or nodular sarcoidosis. This unusual form of sarcoidosis may be misdiagnosed and treated as tuberculosis in countries where the prevalence of tuberculosis is high. Herein, we report on two patients with cavitary sarcoidosis who had been misdiagnosed and treated for tuberculosis.
When the accuracy and cost are considered, differentiation of pleural exudates and transudates can be achieved only by pleural fluid cholesterol level or LDH level; and when two parameters were used together, the accuracy and specificity were higher than that using the criteria of Light et al.
In our opinion, cell typing by TFNA may lead to incorrect results in the presence of poor differentiation, mixed tumours and peripheral epidermoid carcinomas.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
