- Authors discuss the classification of primary cutaneous lymphomas created by the Cutaneous Lymphoma Study Group of the European Organization for Research and Treatment of Cancer (EORTC) in 1996, which is based on the clinical, histological, immunohistochemical and genetic features of cutaneous lymphomas. Unlike the previous histologic classifications it contains well-defined disease entities characterized by their clinical and histological picture, clinical outcome, behaviour and therapeutic response. This classification does not use the term of low grade or high grade lymphoma, but introduces the indolent, aggressive and provisional subgroups in the T-cell lymphomas, and indolent, intermediate and provisional subgroups in the B-cell group. Authors demonstrate the EORTC classification by their own cases calling the attention to the clinical and therapeutic difference between nodal and extranodal lymphomas, and discuss the up-to-date therapeutic possibilities.

- A misaligned stretcher or compressor in a chirped pulse amplification laser introduces residual angular dispersion into the beam, resulting in temporal distortion of the pulse. We demonstrate that an imaging spectrograph is capable for Measuring the angular dispersion of a laser beam by an accuracy of 0.2 murad/min. Using this technique, the analytical expressions of residual angular dispersion of misaligned prism and grating compressors are experimentally proved. Temporal degradations of short pulses due to angular dispersion are studied by measuring the, temporal stretch of 16-fs pulses, while the issues of contrast deterioration are also discussed. It is proved that the simultaneous; measurement of angular dispersion and pulse duration offers the most precise alignment procedure of prismatic and grating compressors.
