Abstract
INTRODUCTION: Neutrophilic panniculitis (NP) is a rare subtype of neutrophilic dermatosis, a group of neutrophil-rich inflammatory skin disorders that can present in association with myeloid neoplasms. NP is defined by the presence of a neutrophilic infiltrate in the fat lobules of the subcutis in the absence of either infection or vasculitis. We herein describe a 65-year-old woman with a recent diagnosis of myelodysplastic syndrome/myeloproliferative neoplasm overlap syndrome (MDS/MPN) who abruptly developed painful, pruritic nodules consistent with NP.
CASE PRESENTATION: A 65-year-old woman with MDS/MPN presented for evaluation of painful and pruritic nodules on her upper and lower extremities. A biopsy revealed a lobular neutrophilic infiltrate in the subcutis without evidence of microorganisms or vasculitis. The patient was diagnosed with NP and treated with oral prednisone. Within 1 month of treatment, she reported complete resolution of the nodules.
DISCUSSION: Similar to other neutrophilic dermatoses, NP may arise in association with hematologic malignancies of myeloid origin, such as MDS/MPN. A literature review revealed that most cases of NP associated with MDS occur after the onset of MDS and respond to systemic corticosteroids, not antibiotics. Infection should be ruled out before initiating treatment with systemic steroids.
CONCLUSION: Although the mechanism is still unknown, it is important for clinicians to be aware that NP is associated with MDS; thus, hematological malignancies should be investigated upon diagnosis of NP. Once diagnosed, NP is easily treated and has an excellent response to systemic corticosteroids.
