[Rare tumors of the cervix: three case reports: rhabdomyosarcoma, granulocytic sarcoma and lymphoma].
Three rare cases of tumours of the cervix are reported: embryonal rhabdomyosarcoma, granulocyte sarcoma and lymphoma. There were particular problems with diagnosis in each case requiring histochemistry, immunohistochemistry and ultrastructure examinations. Embryonal rhabdomyosarcoma is a uncommon tumour in the adult. Clinically, there is a vegetative formation but no botryoid aspect. Striated muscle cell proliferation, suggested by the morphology of the malignant cells was confirmed by immunohistochemistry which demonstrated desmine and vimentine and by the ultrastructural study which demonstrated Z lines in the cytoplasm of the malignant cells. Granulocyte sarcoma is characterized by a non-tumoural non-destructive infiltration of inflammatory-like cells. Their granulocyte nature is confirmed by histochemistry, the Leder's reaction on frozen samples, immunohistochemistry (expression of NP57). Electron microscopy can also be used. The diagnosis of lymphoma is difficult due to the non-tumoural nature of the lymphomatous infiltration which can simulate inflammatory reaction. In our case, the diagnosis was made on the tumoural aspect of the biopsy made in the deep infiltration zone of an adjacent organ (bladder). Immunohistochemistry demonstrated the lymphoid nature of the tumour and identified a B phenotype. The ultrastructural study gave little information.
