Brief Answer:
Lets wait for the scans results
Detailed Answer:
hello again!
The histopathology reports for the
rash are clear except for inflammation is because these dermatological manifestations are secondary to the disease which involves lungs.
And i want you to know that small needle
biopsy is not enough to diagnose. though it is started with. Now the next step should be excisional biopsy of an entire
lymph node and 2 or 3 minimum lymph nodes and if possible with Video Assisted Thoracoscopes assisted biopsy of Hilar lymph nodes would be more specific for the histopathology.
And one should keep in mind the many other etiologies for these manifestations like Infectious mono,
toxoplasmosis , Churg strauss, wegeners, Hypertrophic osteoarthropathies or
tuberculosis etc but to reach that diagnosis your doctors are active and working doing and all these MR and CT scans are for that purpose and it will need some more work up as i mentioned in above answer so be patient and stay in touch.
That leg pains on less than 100 ft walk is explained because of
fever and lung involvement. Body is stressed and
fatigue. illness does that. No worries this issue will resolve Let the kid rest and wait for the result of the scans.
And don't worry these dermatological/ skin manifestations are secondary to the lungs pathology there are many which does that. once that cured skin will regain its texture.
May the odds be ever in your favor.
Kindly close the discussion if you have no more queries to ask. i was happy to be of some help
Take some very good care of your kid.
