Cutaneous leukocytoclastic vasculitis: clinical and laboratory features of 45 patients seen in Ramathibodi Hospital.
Forty-five patients with histologically proved cutaneous leukocytoclastic vasculitis were studied with regard to the clinical features, laboratory findings and etiology. There were 12 males and 33 females, with an age range of 13 to 64 years. The most common skin lesions were palpable purpura which appeared mostly on the lower part of the legs. Renal involvement was the most common systemic manifestation, which occurred in 45 per cent of the patients. Abdominal pain occurred in 42 per cent of the male patients while none of the female patients had this symptom. Arthralgia occurred in 20 per cent of the patients. The most common laboratory abnormalities were elevation of ESR, which was significantly more common in females than in males (P = 0.047). The possible etiology of leukocytoclastic vasculitis was identified in 5 patients, these included streptococcal infection in 2 patients, in the other patients the possible causes were penicillin hypersensitivity, systemic lupus erythematosus and livedoid vasculitis, respectively.
