[Pott's puffy tumor: a rare complication of frontal sinusitis]. / Tumor inflamatorio de Pott: una complicación infrecuente de la sinusitis frontal.

Pott's puffy tumor is a rare complication of frontal sinusitis characterized by swelling and edema in the brow due to a subperiosteal abscess associated with frontal osteomyelitis. Added complications are cellulitis by extension to the orbit and intracranial infection by posterior extension, with high risk of meningitis, intracranial abscess, and venous sinus thrombosis. Early diagnosis and aggressive medical or surgical treatment are essential for optimal recovery of affected patients. In the antibiotic age it is extremely rare, with very few cases described in the recent literature. A case is presented of a Pott inflammatory tumor in a 7 year-old boy, as a complication of acute pansinusitis who presented with front preseptal swelling and intracranial involvement with thrombosis of ophthalmic and superior orbital veins and frontal epidural abscess extending to the subarachnoid space.

Síndrome de Van der Woude / Van der Woude syndrome

El síndrome de Van der Woude se caracteriza por la presencia de hoyuelos (pits) o fístulas labiales, asociados a hendiduras labiales y/o palatinas. También se han asociado otras anomalías congénitas, como defectos cardiacos y anomalías en los miembros. Es un trastorno genético con herenciaa utosómica dominante, con penetrancia casi completa y expresividad variable, estando implicados dos locus génicos. En este artículo repasamos la prevalencia, la etiología y los aspectos clínicos característicos de este síndrome, además de presentar el caso de un recién nacido varón con labio leporino bilateral y apéndices mucosos en el labio inferior. Insistimos en la importancia de la asociación de las hendiduras faciales junto a los pits, por el patrón hereditario del síndrome, así como el diagnóstico diferencial de distintos cuadros clínicos que presentan hoyuelos mucosos

Van der Woude syndrome is characterized by labial pits and/or fistulas, associated with labial and/or palatal cleft. Other congenital anomalies, involving arms, legs or heart, can also te present. It is a genetic disorder with autosomal dominant inheritance nearly complete penetrance and highly variable expressivity. Two genetic loci have been identified. We review the prevalence o etiology and clinical features of this syndrome, and report a case in a male infant with bilateral cleft lips and pits in lowerlip. We stress the importance of the association of facial clefts and pits due to the hereditary pattern of this syndrome, and discuss the differential diagnosis with respect to other syndromes involving pits
