[|Human|] My grandfather a 97 year old who had a stroke over 7 years ago, paralyzed on the left side was noticed to have a lump that has grown to the size of a small egg between the crease of his buttocks an thigh. He does not walk and sits in a wheelchair most of the day. He does not complain of pain to the area. He is otherwise alert. Only med is for BP control. What could this be and what is the cause of it?Please help. Thank you
[|AI|]  Hi. It is possible that he has stasis of blood in that area since he's not moving around. Chronic wounds/lesions which later on become ulceration usually start from this. Is there any associated sign and symptom such as pain or bleeding? Other lesion types must also be ruled-out such as lipoma, fibromyalgia or malignancy. It is best if you consult with a doctor for clinical evaluation. Management (medical and/or surgical if indications are found) will be directed accordingly. Hope this helps. Good day!! ~ Chat Doctor.
