The association between leukocytoclastic vasculitis and solid tumors like renal carcinoma has been infrequently described. We present the case of a 76-year-old woman who began with skin lesions on the legs that were clinically and histologically diagnosed as leukocytoclastic vasculitis. During analysis of the symptoms, she was diagnosed with renal carcinoma. After the tumor was excised, the vasculitis lesions disappeared, with no recurrence during the follow-up period.

    ABSTRACT: Although rare, cutaneous small-vessel vasculitis (CSVV) secondary to solid organ malignancy has been documented. We sought to better understand the frequency, clinical course, therapeutic response, and outcome of CSVV associated with solid organ malignancy. We conducted a retrospective chart review of patients seen between 1996 and 2009 with diagnoses of biopsy-proven cutaneous leukocytoclastic vasculitis and solid organ malignancy separated by less than 12 months. Of 17 patients (mean age, 66.5 years), 10 patients (59%) were male. CSVV occurred before (3 patients; 18%), concurrent with (3 patients; 18%), and after (11 patients; 65%) diagnosis of solid organ malignancy. The most common solid organ malignancy was of the lung (n = 4; 24%). Other associated cancers were breast (n = 3); prostate (n = 2); colon (n = 2); renal (n = 2); thyroid (n = 1); bladder (n = 1); gallbladder (n = 1); and peritoneal (n = 1). Three patients had cutaneous vasculitis in association with malignancy recurrence despite having no cutaneous vasculitis associated with their primary malignancy. Vasculitis remission with use of immunosuppressive agents alone occurred in 9 patients (53%). Eleven patients (65%) were alive at last follow-up (mean follow-up duration, 27 months). This was a retrospective study with a relatively small number of patients. Solid organ malignancy should be considered as a possible cause of CSVV of unknown origin. In contrast to previous reports, our patients were more likely to respond to immunosuppressive therapies without treatment of the associated malignancy and to be alive at last follow-up.

    ABSTRACT: Cutaneous vasculitis may be associated with malignancies, and may behave as a paraneoplastic syndrome. This association has been reported in a variable proportion of patients depending on population selection. We conducted the current study to assess the frequency, clinical features, treatment, and outcome of paraneoplastic vasculitis in a large unselected series of 766 patients with cutaneous vasculitis diagnosed at a single university hospital. Sixteen patients (10 men and 6 women; mean age ± standard deviation, 67.94 ± 14.20 yr; range, 40–85 yr) presenting with cutaneous vasculitis were ultimately diagnosed as having an underlying malignancy. They constituted 3.80% of the 421 adult patients. There were 9 hematologic and 7 solid underlying malignancies. Skin lesions were the initial clinical presentation in all of them, and the median interval from the onset of cutaneous vasculitis to the diagnosis of the malignancy was 17 days (range, 8–50 d). The most frequent skin lesions were palpable purpura (15 patients). Other clinical manifestations included constitutional syndrome (10 patients) and arthralgia and/or arthritis (4 cases). Hematologic cytopenias (11 cases) as well as immature peripheral blood cells (6 cases) were frequently observed in the full blood cell count, especially in those with vasculitis associated with hematologic malignancies. Specific treatment for vasculitis was prescribed in 10 patients; nonsteroidal antiinflammatory drugs (4 patients), corticosteroids (3 patients), chloroquine (1 patient), antihistamines (1 patient), and cyclophosphamide (1 patient). Ten patients died due to the malignancy and 6 patients recovered following malignancy therapy. Patients with paraneoplastic vasculitis were older, more frequently had constitutional syndrome, and less frequently had organ damage due to the vasculitis than the remaining patients with cutaneous vasculitis. In summary, cutaneous paraneoplastic vasculitis is an entity not uncommonly encountered by clinicians. The most common underlying malignancy is generally hematologic. In these cases the presence of cytopenias and immature cells may be red flags for the diagnosis of cancer. In patients with paraneoplastic cutaneous vasculitis, the prognosis depends on the underlying neoplasia.
