[en] There is ample evidence for spontaneous antimelanoma immune reactivity mediated by melanocyte-differentiation-antigens (MDAs). Our aim was to determine whether MDA immunoreactivity is associated with increased tumour-infiltrating lymphocytes (TIL) and macrophages (TIM). A retrospective study was conducted in 30 medium and high grade primary cutaneous melanomas (PCM) as identified by CART-analysis. All of the cases had developed clinical evidence for metastasis within 3 years following surgical excision of the PCM. We used immunohistochemistry and computerized image analysis to quantify MDAs positive cells (Melan A/MART-1, gp100/Pmel 17/HMB45, tyrosinase), CD45R0-positive TIL and LI-protein-positive TIM. A stochastic relationship was present between the MDA immuno-reactivities and the densities in TIL and TIM. An inverse relationship was yielded between TIL and TIM. No specific pattern of PCM immunoreactivity for MDAs, TIL and TIM was found to predict metastases.
