ABSTRACT
CASE Patient is a 63 y/o F with PMH of relapsed AML on treatment with Gilteritinib, Meniere's Disease, asthma, GERD, PRA positive, CKD Stage 3. She was on cycle 1 day + 20 of Gilteritinib when she presented with a neutropenic fever of 101.9. She reported congestion and headache. She was pan cultured and started on empiric Cefepime. Her blood cultures, COVID test and CXR were all negative for sources of infection. Eventually, Cefepime was stopped, and she was transited to PO Cefdinir and Cipro but redeveloped fevers and a maculopapular rash. Repeat pan-cultures were negative. Antibiotics were broadened to Merrem, Linezolid and Cresemba and her fevers improved. However, the rash continued to worsen. There was concern that nodular rash was secondary to infection or possible drug reaction from her antibiotics. Her rash showed no improvement with Benadryl or withholding drugs. She underwent skin punch biopsy before discharge. Biopsy showed florid superficial inflammation with benign ulcer that was highly suggestive of Sweet Syndrome given history of AML. IMPACT/

DISCUSSION:

Sweet syndrome (SS), or acute febrile neutrophilic dermatosis is a rare inflammatory condition characterized by painful cutaneous nodules and neutrophilic infiltrate in the dermis, in the absence of vasculitis. This syndrome is associated with malignancies with AML and MDS being the most reported. Malignancy associated Sweet Syndrome accounts for 15-20% of cases of SS. The atypical production of both pro-inflammatory cytokines (IL - 6, TNF - alpha) and signaling molecules demonstrated in AML is suspected to affect neutrophil function leasing to dermal clumping of the mature neutrophils. In our patient the fever presented prior to the rash with sudden onset of nodular as it has been commonly reported in literature review. Glucocorticoids, either topical or systemic, together with antibiotics and wound care, represent the mainstays of SS therapy. The rash heals without scarring if no ulcerations are present. The signs and symptoms of Sweet syndrome can mimic infection and be treated inaccurately, thus, it is important to make a correct diagnosis. Our patient's tissue cultures were negative for microorganisms. She was started on glucocorticoid with good response in regards to her rash but did have some scars and hyperpigmentation. Unfortunately due to her aggressive AML and complications patient elected to go to Hospice.

CONCLUSION:

When SS is established, the physician should keep a high index of suspicion to search underlying malignancies. Sweet Syndrome generally responds promptly to treatment with glucocorticoid.
