Severe pulmonary arterial hypertension as initial manifestation of intravascular lymphoma: case report.

Intravascular lymphoma (IVL) is a rare and usually fatal disease that belongs to the class of high-grade malignant lymphomas and which is characterized by proliferation of neoplastic lymphoid cells exclusively within the lumina of small blood vessels. Its polymorphic and nonspecific clinical manifestations make antemortem diagnosis very difficult. We report herein a case of IVL revealed by fatal, precapillary, pulmonary arterial hypertension and associated with long-lasting fever.

[Adenomatoid hamartoma of the ethmoid sinus: one case report].

Introduction: Hamartomas are non-malignant malformations or inborn errors of tissue development. In the head and neck region, especially in the nasal cavity and the ethmoid sinuses, they are relatively rare.

Patients And Methods: A case of respiratory epithelial adenomatoid hamartoma of the ethmoid sinus and a review of literature are reported in order to describe the diagnostic and therapeutic management of this tumour.

[Sentinel lymph node biopsy in cervical and endometrial cancers: a feasibility study].

The sentinel lymph node (SLN) biopsy has been proposed for the cancers of the uterus in order to optimize the diagnosis of lymphatic metastases and micrometastases in early stage tumors. Patients with early invasive cervical (n = 8) or endometrial (n = 15) cancers were enrolled. A lymphoscintigraphy was carried out before the intervention.

[Cyst of the parapharyngeal space arising from the branchial arches].

Objectives: We describe a rare case of parapharyngeal space cyst arising from the branchial arches.

Case Report: We report the clinical and radiological (CT and MRI) findings. Surgical resection was performed via a transcervical approach.
