RESUMEN
Pseudosarcoma botryoides is an infrequent vaginal tumor with benign evolution. Its importance lies in to distinguish of sarcoma botryoides, what is usually fatal. A case of vaginal polyp during pregnancy is presented. After cesarean section, polyp was excised and diagnosis of sarcoma botryoides was made. Patient was referred to ION for treatment and her diagnosis was changed to pseudosarcoma by revision of histologic plates. Patient doesn't need further treatment but previous excision, and she is asymptomatic twelve months later. Histologic findings of both tumors are described and confusion between them are noted

The author describes the clinical, radiographic and histological characteristics of three tumors diagnosed as maxillary myxomas at the National Oncological Institute. In the first two patients the tumor was completely excised and 74 and 67 months after surgery, respectively, both patients are well. The third patient underwent curettage of the lesion and, at the time of this report, 3 months after surgery, he has had no recurrence of the tumor and is also well

The author study the clinical history of a patient who initially had a nodule in the left arm and the lesion was excised, had 7 recurrences in the left arm in the following twelve years. The histological examination of one of the nodules showed that it was composed mainly of large ovoid and polygonal cells with abundant eosinophilic cytoplasm, vesicular nuclei and prominent nucleoli. There was an average of 4 mitoses in every 10 high power fields and rare atypical mitoses. The tumor cells showed intense activity with keratin, epithelial membrane antigen and vimentin, and were negative for the CD 31 endothelial marker

The author study the clinical histories and the histopathologic findings in five patients who were hospitalized in the National Oncological Institute, between 1983 and 1993 in whom the diagnosis of Dermatofibrosarcoma protuberans was established. He note the age, sex, localization of the tumor, the frequency and cause of recurrence; he discuss the differential diagnosis with benign fibrous histiocytoma and neurofibroma and, since recurrence may exhibit mixoid changes (as occurred in two of the cases), also discuss the differential diagnosis with mixoid liposarcoma and mixoid malignant fibrous histiocytoma and pseudo sarcomatous nodular fascitis
