Hello and welcome to HCM,
The lump on the thigh region could be due to soft tissue
Few investigations need to be done to find out the origin and character of the lesion.
A X-ray and preferably MRI
needs to be done to know the site of origin of the lesion.
After imaging studies, a fine needle aspiration cytology needs to be done (FNAC).
FNAC is an office procedure in which cells are sampled from the lesion using a thin needle.
The aspirated cells are spread on a slide and stained.
The Cells are studied under a microscope to know the character of the lesion- non-neoplastic or neoplastic..
The management of the lesion will be decided after these investigations.
Consult your doctor for clinical examination, relevant investigations and hence management.
Thanks and take care
Dr Shailja P Wahal
