Lipoma arborescente, tumor poco frecuente como causa de sinovitis extensora de la mano

Abstract

Dentro de los tumores benignos, los lipomas son muy frecuentes. Un subtipo denominado lipoma arborescente, dependiente del tejido sinovial e infiltrado por tejido adiposo, es bastante infrecuente. Se han descrito casos de lipomas arborescentes en diferentes localizaciones corporales, siendo la rodilla la localización más habitual. Cuando se localiza en la muñeca suele ser dependiente del tejido sinovial articulary no de los tendones. Presentamos el caso de 2 pacientes con un lipoma arborescente dependiente de la sinovial de los tendones extensores de la muñeca. Ante la presencia de una tumoración blanda de localización articular, es importante realizar una adecuada evaluación clínica del paciente, así como las pruebas complementarias que sean necesarias para guiar de una forma acertada el tratamiento. Se debe tener en cuenta el lipoma arborescente como diagnóstico diferencial de las tumoraciones blandas localizadas en las superficies articulares.

Giant palmar lipoma – an unusual cause of carpal tunnel syndrome

“…Lipomas are the most frequent tumors in the human body 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ; however, their location in the hand is rare, 1 , 2 , 3 , 4 , 5 , 6 which is a challenge in terms of a diagnostic and therapeutic approach. 3 …”

“…Lipomas are very frequent benign soft tissue tumors, 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 but their incidence in the hand is rare. 1 , 2 , 3 , 4 , 5 , 6 Lipomas are considered giant tumors when they are 5 cm 2 , 3 or more in diameter, and they generally behave as asymptomatic tumefactions, of slow and progressive growth 5 , 8 ; however, sometimes they can lead to symptomatology due to compression of adjacent structures. 1 , 2 , 3 , 5 , 8 , 9 Peripheric nerve compression by lipomas is very uncommon.…”

Few cases of carpal tunnel syndrome resulting from median nerve compression by a lipoma are described in the literature.…”
