ABSTRACT 
Imperforate hymen is a relatively rare congenital anomaly. However, it is not an uncommon cause of lower abdominal pain presenting in teenage girls. Without careful history taking and thorough examination, the condition can be missed easily. We report an imperforate hymen presenting as abdominal pain in three teenage girls aged 12, 12 and 13 years, respectively, within a six-month period. The presentation was reviewed and the various types of hymenotomy were discussed.
