MERENZON, S; SPINER, N  e  BENDJUIA, G. Paraneoplastic cutaneous vasculitis associated with diffuse large B-cell non-Hodgkin's lymphoma. Rev. argent. dermatol. [online]. 2022, vol.103, n.4, pp.11-20. ISSN 1851-300X.

Paraneoplastic cutaneous phenomena are heterogeneous, infrequent and acquired, characterized by the underlying presence of a neoplasm. The most frequently described cutaneous manifestation of paraneoplastic vasculitis is palpable purpura. It can also manifest as urticaria, erythema and ulcers of the lower limbs. We present the case of a 38-year-old patient with a diagnosis of diffuse large B-cell lymphoma and atypical ulcers of intercurrent onset due to leukocytoclastic vasculitis as a paraneoplastic phenomenon. These lesions usually have a parallel course to the neoplasm, so when the neoplasm is treated they may remit, but not when only the cutaneous lesions are treated. We emphasize the importance of preserving a vital tissue in a state of granulation that accompanies the general treatment, in order to favor a rapid epithelialization and prevention of intercurrent infections.
