Characteristics of thymectomized patients with respect to pathology of thymus

Thymus Pathology	N (% of 110)	Age at diagnosis* (years)	Sex (m/f)	Patients with Myasthenic crisis (%)	Number of Myasthenic crisis	Days in ICU (Median & Range)	Ventilatory support
Normal	51 (46.4%)	29.7 ± 13.9	18/33	3 (5.9%)	3	3 & 2–4	3
Hyperplasia	43 (39.1%)	27.4 ± 15.2	14/29	9 (20.9%)	10	7 & 2–30	7
Thymoma	16 (14.5%)	37.3 ± 8.9	9/7	8 (50.0%)	12	9 & 3–38	9

* Analysis of variances indicated that age at diagnosis in thymomatous patients was significantly higher than others (P = 0.007). There was no statistically significant difference regarding other variables.
