Patient's Query

Hello doctor,

I had a cold which led to swollen lymph nodes for five months. A few months back, I had swollen glands in my neck which was present for months. Blood work was abnormal and doctors could not figure out what it was. I have taken multiple blood tests, two CT scans, and a biopsy. I feel fine with no symptoms. The only symptom I ever had was a cold at the beginning which was followed by swollen lymph nodes. I also need to share that my brother had the same thing with the swollen nodes being much smaller. He actually had a cold first and then I got it two weeks later. Both of us had swollen lymph nodes. He has them now in the back of his neck, mine are in the front. My blood work says lymphocytes are abnormal with cytoplasmic villi and also occasional ones show cytoplasmic projections. I am looking for someone to tell me what I have and how it should be treated. Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and understand your concern.

I have reviewed the files you have attached (attachments removed to protect the patient's identity).

Before going into more details, I would like to reassure you that most of your laboratory workups are acceptable and there is no blood test result that is alarming or requires immediate action. Your viral panel that included hepatitis and HIV (human immunodeficiency virus) was all negative. The ANA (antinuclear antibody) is high (1:160) and it means you have an inflammatory process going on.

I hope this has helped you.

Thank you.

The Probable causes

The most likely and the top differential diagnosis of a granulomatous necrotizing lymphadenopathy is tuberculois lymphadenitis. Please note an important point here that having a negative culture does not exclude the diagnosis as many experts rely on the clinical features, histopathological findings, and imaging studies characteristics.

Investigations to be done

1. PPD (purified protein derivative) skin test that is used to show delayed-type hypersensitivity reactions against mycobacterial antigen and give us a clue if you have ever been exposed to tuberculosis and you have the risk to develop it. 2. CXR (chest radiography) to exclude any lung pathology or features of TB. 3. Follow up your TB culture that is kept for long incubation as some strains grow after weeks. 4. Repeat your images or biopsy of the size of the lymphnode is changing (getting bigger). 5. Make sure your doctor have done and immune staining on the biopsy to rule out autoimmune diseases and malignancy.

Differential diagnosis

1. TB (tuberculous) lymphadenitis.

2. Non Tuberculous lymphadenitis.

3. Fat metaplasia.

4. Malignancy like lymphomas.

5. Autoimmune disease.

Treatment plan

Patients who are coming from endemic areas for TB are prone to this infection in many forms so I suggest you seek help from a TB or infectious diseases expert who is familiar with TB cases that presents atypically. As an infectious diseases specialist; I would start TB regimen and observe for improvement in cases like yours.

Preventive measures

Make sure you do not have a non-intentional weight loss, night sweats or fever. If you feel the mass or the lymph node is changing in size, the skin around it is changing, it is becoming painful, or there is a draining sinus, please seek medical advice immediately.

Regarding follow up

Please do not hesitate to ask any question or point out any concern you have. I am always here to help. Regarding your brother, I cannot give an opinion without having at least basic investigations that can help me in giving an honest opinion, as the site of the lymph node is different and therefore the pathology can totally be different relating to the site. I hope I helped you. Thank you.

Patient's Query

Hello doctor,

Thank you for your reply.

I will describe my symptoms in detail again.

A few months back I felt tired and weak one day. I forced myself to work out and then after that, I slept all day. After two weeks, I developed a swollen lymph node and went to the doctor. The doctor gave me Augmentin. I took it for six days and the lymph node almost disappeared. A week later the lymph node got way bigger. I went to another doctor who did a CT scan and said it is normal. He also said that it is an infection and my body is fighting it. The doctor gave me Augmentin for two weeks. And I felt much better, the swelling went way down but it was still there.

After three months, I went to a third doctor who did a CT scan and suggested that I have dry cough. He did not give me anything.

Again after two months, I went to another doctor who did a CT scan, biopsy, FNT, and chest X-ray. TB test was negative. There was nothing else except the swelling which was smaller in size when compared to the prior month. However, two months later, the lymph node disappeared and the doctor said there is something wrong with my blood work. Please clarify.

Thank you.

Hello,

Welcome back to icliniq.com.

I am glad the lymph node disappeared, which means it was most likely a reaction to a previous illness or Kikuchi-Fujimoto disease, which is usually diagnosed by histopathology and has a good prognosis.

I will elaborate on your blood finding in detail. Your peripheral blood smear showed the lymphocytes are pleomorphic where reactive lymphocytes are present. Some lymphocytes are abnormal with cytoplasmic projections.

In detail, we have our lymphocytes increasing when we have an infection, autoimmune disorder, or a disease in the lymphatic system. Lymphocytes are a form of white blood cells that fight against diseases in the body. Lymphocytes with cytoplasmic projections are usually considered abnormal findings for which further testing is needed. It is called immunophenotyping of peripheral blood smear, to compare the cells and to detect white blood cells antigens and markers like these projections to identify the cause.

I have seen your lab reports (attachment removed to protect the patient's identity), and I think it has not been done yet. It will help in checking the cause of the finding that is worrying you. If it is inconclusive, further testing might be performed, and of course, a hematologist's input will be needed.

I hope this answers your question and reassures you for the time being until further test is done on your blood to detect the abnormality and check your cells. Until then, you do not need to do anything or take any medication.

If the findings of the blood immunophenotyping are abnormal, a further check on your blood and bone marrow is needed to investigate lymph proliferative disease.

I hope this has helped you.

Thank you.
