Hi Everyone
My mom has a swollen lymph node in her neck. We went to doctor before 6 months. They told it was normal. After 6 months the node went small, but still we showed to doctor. Went through a CT scan and biopsy. Biopsy told it might be hodgkin's lymphoma. Then, she had 2 biopsy in the same area and the result came as same, where it tolds, it might be hodgkin's lymphoma. Then, in pet scan nodes can be seen on her body somewhere. So doctor come to an conclusion it was hodgkin's lymphoma. On biopsy, they recommended excision biopsy or IHC test. Doctors doesn't performed it. She neither has any symptoms or swollen nodes anywhere outside. Also the node on the neck got disappeared.
have few doubts. Please clarify me
In first biopsy - Moderate cellular smear shows scatterd population of mononucleated and binucletaed cells with prominent nucleoli admixed with eosinophils in a lymphoid background.
Second biopsy: RBC series shows microlytic hypochromic RBC exhibiting mild amisocytosis and WBC series shows Normal in count with Neutrophilic pryondrance. Please tell me what does it mean and why the doctors not confirmed it as hodgkin's lymphoma, they only suggested hodgkin's lymphoma. No excisional biopsy and IHC test were taken. CT scan shows Normal. Also the swollen node on her neck got reduced in this mean time. Is this because of back to back biopsy done on her node reduced that or any other reason?
She got none of the symptoms with the disease where this is happening for over 6 months except the foundings in the PET scan and the suggestive biopsy results.
Doctors are not giving enough information. So, please clarify my doubts.
