Pulmonary Histiocytosis with Use of Chewing Tobacco (Misri) Causing Pulmonary Hypertension in Western India: A Rare Case
Journal Title: Scholars Journal of Medical Case Reports - Year 2018, Vol 6, Issue 6
Abstract
A 55 year old Female non-smoker presented with progressive shortness of breath for last 8 months. There was no significant past medical history. On physical examination, she was ectomorphic, febrile and dyspnoeic with respiratory rate of 34/min; not cyanosed but pedal edema was present. Respiratory Examination reveals use of accessory muscles of respiration & widespread crepitations and wheezes over both lungs. CVS Examination show right ventricular lift, loud second heart sound with accentuated pulmonic component and tricuspid regurgitation murmur on auscultation. All blood tests were normal. Chest X-ray showed non-specific interstitial infiltrates bilaterally. High resolution CT scan was consistent with reticulo-nodular and cystic changes in upper and middle lobes and ground glass appearance in posterior basal lobes of lungs. There was mix obstructive and restrictive pattern on pulmonary function tests. Surgical Lung biopsy was taken which confirmed Pulmonary Langerhans cell histiocytosis. Patient was advised to stop smoking and started on medical management. Unfortunately patient lost follow up and presented again with worsening symptoms and clinical signs of right sided heart failure. Echocardiography showed severe pulmonary hypertension. Patient was started on treatment for pulmonary hypertension which made little symptomatic improvement but her symptoms got worsen over time and is now being considered for lung transplantation. Learning points/conclusion: Pulmonary function tests may be of normal, obstructive, restrictive or mixed pattern as is the case with our patient. Pulmonary hypertension is a common and under recognized complication due to direct vasculopathy (arterioles but predominantly venules) and can occur at any time during course of disease as it may or may not co-relate with lung function abnormalities and severity of parenchymal involvement. Investigations for pulmonary hypertension should be done early to prevent unnecessary delay in management.
