[Malignant nongranulomatous pulmonary hypertension in a patient addicted to parenteral drugs].

We report the first case in the Spanish literature of pulmonary hypertension (PHT) caused by vascular sclerosis in a parenteral drug abuser female. The clinical diagnosis of PHT was confirmed in the necropsy study, which ruled out granulomas and discovered only vascular sclerosis and hypertrophy as causative factors of the clinical picture. The different etiological and pathogenetical mechanisms reported in the literature as causing PHT in this type of patients are reviewed.

Ameloblastic fibrosarcoma: report of a case. Immunohistochemical study and review of the literature.

Ameloblastic fibrosarcoma is a rare malignant odontogenic tumour characterized by a benign epithelial component within a malignant fibrous stroma. Its behaviour is relatively benign, with absence of metastatic disease, and the prognosis is reported to be good. It is a paradoxical neoplasm with "sarcomatous" morphological and immunohistochemical patterns but with a favourable clinical course. We report a new case of this tumour in a mandibular ramus of a 31-years-old male patient, that was surgically excised and treated with adjuvant chemotherapy and radiotherapy. Five years later the patient is free of disease. The growth potential of ameloblastic fibrosarcoma is evaluated and compared with a related lesion, the ameloblastic fibroma. The sarcomatous mesenchymal component of ameloblastic fibrosarcoma is positive to Ki67, PCNA and p53, in front of the negativity of ameloblastic fibroma.

The synovial sarcomas constitute the 7-10% of the soft tissue malign tumors, with a preferred location in the limbs. In the head and neck a 5% of the totality are placed. We present one case of retropharyngeal synovial sarcoma and the accomplished treatment, together with a revision of the bibliography.

[Adenocarcinoma of the nose and paranasal sinuses. Presentation of 3 cases].

Three cases of intestinal type adenocarcinomas of the nose and sinuses are described. In two of them the tumors were associated with an extended exposure to wood dust, while no association with any known exposure factor was detected in the third. Clinical history, pathology, treatment and follow-up of each case are reviewed.

[Pleomorphic adenoma of the nasal cavity. Presentation of a case].

We display a case of a female patient with a pleomorphic adenoma localized in the nasal fossa, with 10 years of evolution and that has been extirpated by an external way. We review the bibliography, we emphasize the rareness of the locality and make considerations about clinic, prognostication and treatment.

[Chondrosarcoma of the larynx: review of the Western literature and presentation of a new case].

We present the case of a 70 year old man with cricoid chondrosarcoma treated with total laryngectomy. This report reviews the occidental literature, with nine cases reported by national authors in the las 25 years. We have recollected 104 laryngeal chondrosarcoma, in all. Clinical and diagnostical data, location, and treatment were analysed and compared with our case.
