Lymphoma rash

Hello Doctor: Recently, I've been feeling somewhat unwell, and I'm not sure if it qualifies as an illness.
I kindly ask for your preliminary assessment.
Around the end of April this year, I noticed a swollen lymph node in my neck, which was accompanied by fever and some acute symptoms, but I did not have a cough or runny nose.
At that time, I felt it was not like a typical cold.
Nevertheless, I went to see a general practitioner, who noted some phlegm in my throat and prescribed cold medication.
Eventually, the symptoms gradually subsided.
However, about a week later, I started developing rashes.
They mostly appeared on my hands and feet, small and dark red, painless and itchless, lasting about four to five days before disappearing, only to reappear shortly after.
This has continued for four months now, with one or two lymph nodes in my neck swelling again, the rashes still recurring, and I've been experiencing a slight fever.
I've considered many possibilities.
Initially, I thought maybe I was overthinking it, as swollen lymph nodes can occur frequently, and there are many causes for rashes, so perhaps they are unrelated.
However, I still feel something is not right.
Additionally, I visited the countryside the day before these symptoms appeared, and I wondered if it could be scrub typhus.
But after researching online, it seems scrub typhus has an incubation period, and rashes typically appear for only 9 to 10 days, according to what I found.
In summary, I am quite troubled and unsure if I have an illness, and if so, what it might be.
Based on your experience, do you have any preliminary directions or insights? What could be wrong with me, and can you provide a rough estimate? Thank you very much!

Hello: 1.
If you have a fever along with a rash and have recently visited the beach or mountains, it is possible that you may have contracted scrub typhus.
2.
It is recommended that you check for rashes or insect bite marks in areas such as the armpits, around the navel, the groin, near the breasts, and on the buttocks during your daily shower.
3.
If you still have concerns, please consult an infectious disease specialist.
Thank you!

More Info

Lymphadenopathy and rash can be indicative of a variety of medical conditions, and your symptoms warrant careful consideration. Based on your description, you have experienced swollen lymph nodes in your neck, fever, and a recurring rash on your hands and feet. These symptoms have persisted for several months, which is concerning and suggests that further evaluation is necessary.

Lymphadenopathy, or swollen lymph nodes, often occurs as a response to infection, inflammation, or malignancy. In your case, the initial swelling accompanied by fever suggests an acute process, possibly an infection. Common causes of lymphadenopathy include viral infections (such as infectious mononucleosis), bacterial infections (like strep throat), and less commonly, systemic conditions like autoimmune diseases.

The rash you describe as small, dark red, and non-itchy could be related to several conditions. It’s important to note that rashes can be associated with infections, allergic reactions, or systemic diseases. Given that your rash appears intermittently and correlates with the lymphadenopathy, it may suggest an underlying systemic issue rather than a localized skin condition.

Considering your recent visit to a rural area, it is prudent to consider vector-borne diseases, such as rickettsial infections (like scrub typhus) or Lyme disease, especially if you had potential exposure to ticks or other vectors. However, as you mentioned, the incubation period for these diseases can vary, and the rash characteristics may not align perfectly with those conditions.

Your symptoms of persistent low-grade fever, recurrent lymphadenopathy, and rash could also suggest a chronic infection or an autoimmune disorder. Conditions such as systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA) can present with similar symptoms, including lymphadenopathy and skin manifestations. These diseases often require serological tests and imaging studies for proper diagnosis.

Given the complexity of your symptoms and their duration, it is crucial to seek a thorough evaluation from a healthcare provider. They may recommend blood tests, imaging studies (like ultrasound of the lymph nodes), and possibly a biopsy of the lymph nodes if there is suspicion of malignancy or a specific infectious process.
In summary, while it is difficult to provide a definitive diagnosis based solely on your symptoms, the combination of lymphadenopathy, rash, and fever suggests that you should pursue further medical evaluation. It is essential to address these symptoms promptly to rule out serious conditions and to receive appropriate treatment. Please consult a healthcare professional who can perform a comprehensive assessment and guide you through the necessary diagnostic steps.
