[Intramuscular epithelioid hemangioma of the parapharyngeal space]. / Hemangioma epitelioide intramuscular del espacio parafaríngeo.

A clinical case of epithelioid hemangioma of the scalene muscle that occupied the parapharyngeal space is reported. The patient was a 34 year old man with a 2-month history of sensation of pharyngeal foreign body and mild dysphagia. The exploration revealed a tumor of the posterior and lateral wall of the oropharynx that extended from the rhinopharynx to the hypopharynx. The diagnostic sequence included CT, MRI, Doppler echography, and arteriography, which identified a right post-styloid tumor located behind and medial to the jugular vein, internal carotid artery, and vagal nerve, but did not affect arterial blood flow. The patient underwent surgical treatment consisting of lateral cervicotomy, tumor excision, and histological study.

[Congenital mesoblastic nephroma in childhood. Our experience apropos of 3 cases]. / Nefroma mesoblástico congénito de la infancia. Nuestra experiencia a propósito de 3 casos.

Congenital mesoblastic nephroma (CMN) is a rare, generally benign renal tumor. A better knowledge of its natural history has changed the therapeutic approach. Currently, aggressive therapy must be exclusively reserved for the sarcomatous forms or Wilms' tumor with sarcomatoid features. The cell variant reported in our series was treated with efficacy by surgery alone. Early recognition of the lesion, preferably prenatally, is warranted in order to perform surgery early or detect hydrops fetalis, a possible complication of pregnancy.
