IL-32 is detected in cutaneous and mucosal lesions of ATL patients. Fragments of cutaneous lesions (CL, n = 23, A) or mucosal lesions (ML, n = 9, B) and healthy tissues (skin, n = 8; mucosa, n = 7) were included in paraffin and sections were submitted to IHC for IL-32. After reaction, the expression of IL-32 was determined through positive cells, analysed under light microscopy. The data represent individuals and medians values. *p < 0.05. Panel C: photomicrography of skin control. Panel D: photomicrography of CL lesion positive for IL-32. Panel E: photomicrography of mucosa control. Panel F: photomicrography of ML lesion positive for IL-32.
