[Aponeurotic fibromatosis with calcification].

Clinico-morphological description of one case of aponeurotic fibromatosis with calcification in a 59-year-old man. Fibromatosis was localized in the proximal part of the limb and had a nodular appearance. Histologically, roundish and oval cells with "swollen" nuclei forming a sort of parallel rows, foci of calcification and chondroid metaplasia characteristic for such cases were found.

[Mesenchymal chondrosarcoma of soft tissues].

Clinical and morphological data on 2 observations of soft tissue mesenchymal chondrosarcoma (both in women) are given. In one case the primary tumour was localised in the soft tissues of the posterior part of the hip with subsequent metastasis into the lungs and the soft tissues of the head. In other case the tumour was localised in the soft tissues of the leg and no metastasis was detected.
