Neurologic manifestation as initial presentation in a case of hereditary haemorrhagic telangiectasia.

Hereditary Haemorrhagic Telangiectasia (HHT), or Osler-Weber-Rendu syndrome is an uncommon autosomal dominant multi-organ condition of vascular dysplasias. We describe a 19 year old Indian female who presented with cerebral abscess secondary to paradoxical emboli from pulmonary arteriovenous malformations (PAVMs) associated with HHT. Cerebral, pulmonary, hepatic and gastrointestinal involvement can be life-threatening and it is important to have lifelong follow-ups on these patients.

Bronchial mucoepidermoid carcinoma: an unusual cause of complex cystic lung mass in a young man.

Bronchial mucopeidermoid carcinoma is extremely rare, with an incidence of 0.1 to 0.2% of all primary lung tumors. It usually presents as an endobronchial mass with either partial or total occlusion of the airway lumen. Common clinical presentations are hemoptysis, airway obstruction, and recurrent atelectasis or pneumonia. We present a 27-year-old man who complained of chronic cough as a result of bronchial mucopeidermoid carcinoma with resultant obstructive lung changes.

"Black bronchoscopy"-a case of endobronchial metastases from melanoma.

The presence of black pigmentation in the airways during flexible bronchoscopy is uncommon. We report an unusual case of "black bronchoscopy" as a result of endobronchial metastases in a 77-year-old Chinese man, who presented with hemoptysis and postobstructive pneumonia 3 years after initial excision of a skin melanoma. Chest radiograph showed right lower lobe consolidation and collapse. Bronchoscopy showed narrowed airways with black pigmentation involving the lower trachea and right main bronchus. Biopsy confirmed metastatic melanoma. The patient received palliative radiation and died 6 months later. We review the causes of black airway pigmentation. We also briefly review the prevalence, clinical presentation, and prognosis of endobronchial metastases.
