Amyloidosis is an uncommon heterogeneous and multi‐systemic disease characterized by extracellular amyloid deposition. The size of proteins varies and forms a part of local disease or systemic process. Light chain amyloidosis (AL) is the most prevalent form of systemic amyloidosis which may also be seen in localized disease. Isolated tracheobronchial amyloidosis (TBA) is rather unusual with local amyloid deposition which may pose a diagnostic dilemma with subsequent therapeutic challenge. Awareness of such a presentation is crucial in the diagnosis of this rare disease. We describe three cases who presented with haemoptysis, which on further evaluation were diagnosed as isolated TBA, and a review of literature.

T-cell lymphoblastic lymphoma (T-LBL) is a rare and aggressive variant of non-Hodgkin lymphoma (NHL). We present a case of T-LBL presenting as a right-side pleural effusion in a middle-aged person and biochemical characteristics similar to tuberculosis [lymphocytic exudative with high adenosine deaminase (ADA)] that confuses the diagnosis and delays the treatment. Thoracoscopy was suggestive of multiple varying size nodular lesions which may be characteristic of the disease. This case also emphasizes that all lymphocytic exudative effusions with elevated ADA are not tuberculosis, especially in middle-aged and elderly populations. Before labeling a diagnosis of tubercular pleural effusions, all other possible diagnoses should be ruled out.

The Percutaneous technique for tracheostomy has become the standard procedure, due to its ease in placement, minimal complications, and has almost replaced the traditional open (surgical) tracheostomy in intensive care units. We describe a case of broken tracheal cartilage which slipped into the tracheobronchial tree following percutaneous tracheostomy (PCT), impinging and causing collapse of medial basal segment of right lower lobe.

Postintubation tracheal stenosis is preventable yet commonly occurring clinical condition. Early in the disease, nonspecific symptoms may predominate but once the stenosis reaches a critical stage life-threatening respiratory compromise may ensue. Bronchoscopic interventions are an invaluable tool in the management both as a primary treatment and as an interim procedure before the surgery. Optical dilatational tracheoscopy is a safe and minimally invasive procedure in the treatment of benign tracheal stenosis. Involvement of multidisciplinary team early in the treatment planning gives the best possible results.
