Rare interstitial lung disease: Pulmonary Langerhans Cell Histiocytosis in a young non smoking Indian female

A Case of Nonsmoker Pulmonary Langerhans Cell Histiocytosis With Multiple Pulmonary Nodules Disappeared and Appeared

We present a non-smoker woman in her 40s with PLCH who presented with atypical imaging findings of multiple pulmonary noncavitary nodules without air cysts with repeated waxing and waning.

Langerhans cell histiocytosis in adults: literature review

Langerhans cells histiocytosis is a variant of malignant histiocytosis. The course and symptoms vary. patients with localized forms have a better prognosis, because local therapy is effective. patients with multifocal forms of histiocytosis receive systemic drug therapy, which cures some of the patients. This review provides up-to-date data about typical presentation of the organ involvement, diagnosis, course and therapy of various forms of Langerhans cells histiocytosis.

Pulmonary Langerhans Cell Histiocytosis in a young Non-Smoking Female --Too many Rituals spoil the Lung

Pulmonary Langerhans cell histiocytosis (PLCH) is a rare idiopathic cystic interstitial granulomatous lung disease seen almost exclusively in cigarette smokers. It typically occurs between 20-40 years of age and equally distributed among both sexes. Management includes smoking cessation, avoidance of second-hand smoke, and close follow-up. Corticosteroids may be required in those with symptomatic disease with worsening lung function despite smoking cessation and progressive nodular stage of the disease. Here, we report an interesting case of biopsy proven PLCH in a young never smoker female. Detailed questioning revealed significant exposure to incense smoke, highlighting a rare presentation of non-cigarette smoke related PLCH. Avoidance of incense smoke combined with oral prednisolone (0.5mg/kg) tapered over 6 months led to complete resolution of symptoms, disappearance of nodules in high resolution computed tomography (HRCT) of the thorax, and improvement in lung function.
