37-year-old woman with a history of Crohn's
disease, SLE (anti-DNA 1/40, ANA 1/320 fine
mottled pattern, complement consumption, diffuse
alopecia, leukopenia) and hypothyroidism on
treatment with adalimumab 40 mg, azathioprine
100 mg day, hydroxychloroquine 200 mg twice
daily, meprednisone 4 mg day, levothyroxine 100
mcg day.
She presented afternoon fever of 38 - 39 ° C,
intermittent of 2 daily records accompanied by
night sweats, mild weight loss, arthromyalgia,
diffuse alopecia. Upon pallor examination,
temperature of 38.6 ° C, HR 104 bpm, blood
pressure of 100/60 mmHg, respiratory rate of 18
per minute, with ambient air oxygen saturation of
98%, diffuse alopecia, vasculitic-type reticulate on
hands, with mobile adenopathies, renitent, not
painful, less than 1 cm, in posterior region and
laterocervical, supraclavicular and axillary
bilateral (the largest in left axillary vertex of 2cm).
Rest of the exam without alterations. In the
laboratory, inflammatory anemia (Hb 7.7 gr%),
leukopenia with mild neutropenia and frank
lymphopenia, mild elevation of 22 mm
erythrosedimentation and C-reactive protein of 20
mg / l, hypoalbuminemia, hypocomplementemia,
ANA 1/5120 fine mottled pattern, anti DNA 1/40.
Renal, hepatic function and urinary sediment were
normal.
Antibiotic treatment is started with ampicillin -
sulbactam, suspending adalimumab and
azathioprine. Blood cultures, urine cultures,
procalcitonin, PPD, serology for HIV, Hepatitis B
and C, VDRL, chlamydia, EBV, influenza A-B
that were negative, only highlight cytomegalovirus
with positive IgM, but with negative early antigen.
Chest tomography: bilateral axillary adenopathies;
the largest in the left axilla of 21 x 12 mm; rest
without alterations. TAC abdomen-pelvis diffuse
thickening of the terminal ileum, with a maximum
thickness of 8 mm, reduction of light, mesenteric
and retroperitoneal nodes smaller than 10 mm.
Based on the physical examination and laboratory
tests, SLE activity was diagnosed and surgical
removal of the left axillary lymph node, which
showed follicular hyperplasia in the cortex and
medulla, prominent germinal centers, in some of
the hyalinizing vessels follicles, was decided.
interfollicular plasmocytes with eosinophilic
cytoplasmic globules. Positive
immunohistochemistry for HHV-8, indicating
diagnosis of ECM associated with HHV-8.
Therapy was started with prednisone 40 mg for 10
days with a decrease in lymphadenopathy.
Conclusions
The histopathological findings of CD in patients
with SLE are rarely reported. MCD presents as a
systemic disease with disseminated
lymphadenopathy, constitutional symptoms,
autoimmune abnormalities, recurrent and
laboratory infections with signs and symptoms
superimposed with autoimmune diseases.
In the differential diagnosis, in addition to the
lymphadenopathies of SLE and hematological
malignancies, other diseases such as tuberculosis,
sarcoidosis, metastasis and Kikuchi-Fujimoto
disease must be taken into account. The treatment
includes high doses of steroids, radiotherapy and
systemic chemotherapy according to the different
types of CD. From a therapeutic perspective, we
highlight the possibility of CD morphology in
patients with lymphadenopathy due to SLE.
