Cutaneous Plasmacytosis Associated with Ehrlichiosis in an African-American Patient.

Cutaneous plasmacytosis is a rare disease that presents clinically with multiple red-brown papules and plaques with minimal to no epidermal change. Histopathologic findings include a perivascular dermal infiltration of polyclonal plasma cells. The etiology of cutaneous plasmacytosis is unknown, but hypothesized to be due to persistent or repeated antigenic stimulation. Ehrlichia represents a family of obligate intracellular bacteria that have been associated with the development of plasma cell dyscrasias in the veterinary literature. We present a case of a 67-year-old male patient with the development of progressively worsening cutaneous plasmacytosis following prolonged hospitalization secondary to ehrlichiosis sepsis. The patient initially presented with isolated cutaneous involvement and normal laboratory findings that eventually progressed to include multiple laboratory abnormalities, including anemia, hyperproteinemia, and elevated serum creatinine. Further diagnostic workup was declined by the patient despite evidence of progression to systemic plasmacytosis or multiple myeloma. Copyright © 2020. Matrix Medical Communications.
