title: [Cytophotometric and electron microscopic study of chronic human skin lymphomas. I. A study of skin manifestations].
abstract: Electron microscopic and cytophotometric studies of low-grade malignant cutaneous lymphomas and non-malignant skin diseases revealed substantial differences between these groups of diseases. In the latter case, the DNA content per nucleus is diploid but in the former an atypical distribution of DNA content per nucleus (more than 5% aneuploid and polyploid nuclei) is observed in addition to a significant excess of the mean DNA content per nucleus above the diploid standard level. In lymphomas electron microscopy reveals clusters of atypical lymphoid cells with irregularly shaped nuclei, nuclear pockets, nuclear extrusions, network of cytoplasmic microfilaments. These features never occur with skin diseases. The data obtained can be helpful in the diagnostics of the low-grade malignant cutaneous lymphomas.
