title: [Deep fascicular fibromatoses in diagnostic material from the pathomorphology department of the Institute of Mother and Child].
abstract: We studied 17 cases of deep fascicular fibromatoses of various location in children and adolescents from 7 months to 16 years. Basic proliferative cells consisted of mature cells of the connective tissue slightly changed cytologic features but without atypia. We observed scanty regular mitoses. Histological structure of individual tumours and fields in the same tumours differed in the degree of collagenization, vascularization and abundance of cells. In four cases proliferations were differentiated with neurofibromatosis, in one case with fibrosarcoma of high-degree differentiation. In four cases the tumours were of desmoid structure. In two cases of mesenteric location of the proliferation we found foci of cartilagous metaplasia, which in one case after several recurrences transformed the tumour into a chondrosarcoma.
