Adult onset immunodeficiency associated with thymoma is a rare condition. The combination of hypogammaglobulinemia, reduced number of peripheral B and CD4+ T cells, along with thymoma constitutes Good's syndrome (GS). This immunodeficiency condition is often complicated with opportunistic infection with organisms, like bacteria (Haemophilus influenzae, Streptococcus pneumonia etc), viruses (Cytomegalovirus, Herpes simplex etc), fungi and protozoa.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by progressive deterioration of respiratory function along with systemic effects which have a great impact on health-related quality of life (HRQoL). Classification of severity of airflow limitation in COPD does not represent the clinical consequences of COPD. Hence, combined COPD assessment should be preferred.

Incidence of thymic malignancies is very low. Thymoma, a tumor of thymus gland, is of epithelial origin and is most common anterior mediastinal tumor. In most cases, thymomas are localized and locally advanced thymomas may rarely present with superior vena caval obstruction (SVCO) and malignant pleural deposits.

Schwannomas are rare neurogenic tumor originating from Schwann cells of the nerve sheath, most frequently encountered type of posterior mediastinal tumors. In most cases, schwannomas are benign, malignant and multiple schwannomas are rare. Histopathologically, the tumor is composed of fascicles of spindle cells, which are strongly positive for S-100 proteins.

Malignant tumours in the apices of the lungs, especially bronchogenic carcinoma (Pancoast tumours), are the most common cause of Pancoast' syndrome which presents with shoulder or arm pain radiating along the medial aspect of forearm and weakness of small muscles of hand with wasting of hypothenar eminence due to neoplastic involvement of C8 and T1 and T2 nerve roots of brachial plexus. There are a number of benign conditions which may lead to Pancoast's syndrome; fungal abscess located in the apex of lung is one of them. Oral or intravenous antifungals are the treatment of choice in this case and complete recovery is usual, whereas, surgical resection followed by chemoradiotherapy is the treatment of choice in case of Pancoast's syndrome due to lung cancers.

Tuberculosis (TB) is the most common cause of cervical lymphadenopathy in the TB-endemic zone, like India but it can also mimic other diseases. Four cases of cervical lymphadenopathy presented to us as initial treatment failure after completion of six months of antitubercular drugs (ATD), including rifampicin, isoniazid, pyrazinamide, and ethambutol. All were diagnosed as having tuberculosis either by fine needle aspiration cytology or clinically from outside our institution.

Allergic Bronchopulmonary aspergillosis (ABPA) commonly presents with persistently uncontrolled asthma, despite of the therapy with highest possible anti-asthma medications. Most common cause of ABPA is Aspergillus fumigates. Hence, ABPA is one of the important differential diagnoses of difficult-to-treat asthma.

Kikuchi-Fujimoto disease, characterized by histiocytic necrotizing lymphadenitis, closely mimics tuberculosis, and lymphoma are two most common etiologies of cervical lymphadenitis. It is a rare, benign, and self-limited disease. Viral infections or autoimmunity are hypothesized as its etiology, but no causal relationship is definitely established till date.

Pancoast syndrome is a common presentation of bronchogenic carcinoma, but other malignancies are rarely cited as its cause. Pancoast syndrome due to non-Hodgkin's lymphoma is rarely described in the literature. Here, we report a case of Pancoast syndrome due to non-Hodgkin's lymphoma to increase the awareness of the clinicians regarding essentiality of tissue diagnosis of Pancoast tumor before starting the treatment.

Drug-induced flu-like syndrome is very rare. It is mainly produced by rifampicin. We report a case of pulmonary tuberculosis (PTB) that developed isoniazid-induced flu-like syndrome, but could be cured with a modified regimen replacing isoniazid with levofloxacin.

Context: Prevalence of tuberculous pleural effusion is very high in the Asian subcontinent but very few studies have come up from this part of the world about the course of recovery of pulmonary functions after institution of anti-tubercular therapy (ATT) and thoracentesis.

Aims: To study initial lung function impairment, changes over time after institution of ATT and thoracentesis and residual abnormalities left at the end of six months of treatment.

Settings And Design: Randomized open level interventional study over two years in 52 patients at a tertiary level teaching hospital.
