The clinical and laboratory data of the patients were recorded and further analyzed; 334 patients were included with 195 males and 139 females. The mean age at onset was 35.8 ± 11.1 years. The most frequent initial manifestations were oral aphthae and genital ulceration. The common manifestations observed throughout the disease course were oral aphthae, genital ulceration and various cutaneous lesions.
