this sounds like the description of a pressure ulcer to me. and it definitely deserves to be examined by a medical professional. pressure ulcers (decubitus ulcers or bed sores) in the elderly are not uncommon. left untreated they can become infected and cause serious illness. a pressure ulcer generally isn't cause to run to the emergency room but i'd certainly suggest you make an appointment with this lady's primary care provider to take a look at this. meanwhile it might help to get your loved one a sheepskin or some layers of foam alternative to sit on. this may help relieve the pressure that's causing this developing ulcer (assuming that's what it is). please don't put any type of adhesive bandage on this or apply anything using adhesive tape. this can cause tearing of the skin in elderly people. i hope you get this checked out soon and i wish you and your loved one all the best!
87 yr old woman. chemo for bladder cancer. constant sitter. has a growth on the buttocks. looks like a lazy eye. flap. the flap laps over what seems to be an abcess or boil but gets very sore when touched. recent x-ray showed possible calcifications in the area. seems like the flap is made up of fat tissue that has been pulled up from her buttocks. flap located right around the pelvis bone. top of the buttock area. any ideas of what this could be?
