Heamatocolpos is seen in: September 2005
**Core Concept**
Heamatocolpos refers to the accumulation of blood in the vagina, typically resulting from a congenital or acquired obstruction of the vaginal outlet. This condition can be caused by various factors, including imperforate hymen, vaginal atresia, or other obstructive lesions.
**Why the Correct Answer is Right**
Heamatocolpos occurs when the normal flow of menstrual blood is blocked, leading to a buildup of blood in the vagina. This can cause the vagina to become distended and may lead to discomfort, pain, and other complications. The correct answer is associated with an imperforate hymen, a congenital condition where the hymen is completely covering the vaginal opening, preventing menstrual blood from flowing out.
