Bronchiolar carcinoma

is a primary lung tumor probably originating in the terminal bronchioles in the peripheral portions of the lung. It has a relatively benign histologic appearance and is composed of tall columnar or cuboidal mucus-secreting cells lying on an intact alveolar septum.

Essentials of Diagnosis:-


• Patients are in the age group of 50 to 60 years.
• Chest pain with copious watery or mucoid sputum.
• Bilateral involvement is very common.
• Dyspnoea, cyanosis, dullness on percussion, clubb-
ing, cor pulmonale, etc.
• Chest X-ray shows bilateral, discrete or diffuse
lesions.
• Sputum cytology is diagnostic.
If the lesion is unilateral, localised without extrapul-
monary metastasis surgical removal is indicated.
• Sputum cytology, bronchoscopy, biopsy of palpable nodes, mediastinoscopy, tomography and scanning procedures determine the exact location, extent and
spread of the disease.

Investigation:-

– CXR

-CT CHEST

-MRI CHEST IF REQUIRED

Treatment:-

-Early detection and surgical removal before meta- stasis occurs.
-Small doses of cytotoxic drugs with radiotherapy offer some hope of improved palliation.

As a precautionary measure chest X-ray once a year for smokers above 40 years of age is recom- mended.
