[Treatment of early glottic carcinoma with transoral laser CO2].

OBJECTIVE: We present our outcome in the treatment of 125 patients with malignant glottic lesions between 1992 and 2003 in a retrospective study. PATIENT AND METHODS: We analyze 125 cases of patients, with previously untreated carcinoma of the larynx with histological diagnosis, treated with Transoral Laser Microresection. We will pay special attention to those tumors involving the Anterior Commissure. We will also analyze several parameters related to the post and intraoperatory histopathological report, in order to decide adjuvant therapies. We will also analyze the technique indications, complications, hospital length of stay, oncologic and functional outcomes, survival and follow up of recurrences. OUTCOMES AND CONCLUSION: Transoral laser microresection is an effective and functional preserving procedure, and nowadays the base of the treatment of early glottic carcinoma. Anterior Commissure involvement is a prognostic factor. Sometimes complementary therapies are needed based on by the histopathological report.

[Primitive neuroectodermal tumor/extraosseus Ewing sarcoma of the temporal bone].

The term primitive neuroectodermal tumor (PNET) should be included in the differential diagnosis of small round blue cell tumors, which come from the neural crest and explain their neuroectodermal character. This is one of the most indifferentiated histological types of malignant tumors. In the PNET family, we high light the Ewing's Sarcoma, that is frecuently located in bony sites and has a less frequent localization in soft tissues. We focus on one atypic case of PNET/Extraosseus Ewing's Sarcoma that involves the external auditory canal and infiltrates the temporal bone. Surgery followed by postoperative chemotherapy and radiation offers the best local control of the disease.
