INDORE: A patient with a rare blood group left doctors stumped at a city hospital on Saturday. Shabana Mansoori, a 26-year-around anaemic patient, has O+ blood but she could not be given blood from normal donors of the same group as tests revealed that Mansoori belonged to the rare "Bombay blood group" that didn't match with any of the other groups.

First identified in Mumbai, from which the group derives its name, so far it is said that there have been just 179 such cases reported in India.
