[Morphologic features of tumor stage lesions of mycosis fungoïdes (author's transl)].
A morphological analysis was carried out on a series of five patients, with tumor stage lesions of mycosis fungoides. The histological findings of skin, lymph nodes, spleen, liver and bone marrow were investigated. Histologically the cutaneous infiltrate consisted of large cells (mycosis cells) and small atypical lymphoid cells (Lutzner cells). Among the large cells, which predominated in number, two principal types of cell could be distinguished: lymphoid cells comparable to the Lutzner cells because of their nuclear configuration, and poorly differentiated basophilic and pyroninophilic cells with irregular nucleus ("reticulum" cells?) or regular nucleus ("T-immunoblasts"?). Ultrastructural data of cutaneous lesion obtained for study from only one patient, were consistent with these findings. Lesions of lymph nodes and viscera consisted of a cellular composition which closely resembled that of cutaneous lesions. In particular, the large so-called mycosis cells were always found and represented a supportive histologic feature in identifying this disease.
