Objective Analyzing clinical features of college students’ spontaneous pneumothorax to provide a reference to clinical diagnosis and treatment in early period. Method Analyzing clinical features of 48 cases of student patients in my hospital who were diagnosed as patients of spontaneous pneumothorax. Results In the 48 cases

45 cases have no general disease

which amounts to 93.7%; patients in 46 cases are male

which amounts to 95.8% of all; patients of 38 cases are of leptosomic type

which amounts to 79.2%. There are 44 cases who have a chief symptom of thoracalgia

which amounts to 91.7%. According to the rate of lung compression

26 cases are less than 20%

which amounts to 54.2% of the whole cases;18 cases are from 20% to 50%

which amounts to 37.5% of the whole cases; 4 cases are above 50%

which amounts to 8.3% of the whole cases. In the 48 cases

45 cases were cured （the cure rate amounts to 93.7%）; the other three cases were sent to upper hospital to receive thoracocentesis operation.Conclusions Most cases of college students who suffer spontaneous pneumothorax have a common feature of spontaneity

of which most often found in male and leptosomic type people. The common clinical symptom of spontaneous pneumothorax is thoracalgia. The rate of lung compression in most cases is under 20% or between 20% and 50%.All cases have received a good treatment effect. When students present a chief symptom of paroxysmal thoracalgia

doctors should give students a chest X-ray in time to make a correct diagnosis and treatment as early as possible.
