Abstract

El sarcoma sinovial es un tumor poco frecuente de partes blandas periarticulares de los miembros. Está formado por células sinoviales que adoptan dos tipos distintos. El elemento sinovial de aspecto epitelioide tapizando hendiduras, formando seudoacinos o con disposición membraniforme y en acúmulos compactos. El elemento fibromatoso con células fusiformes dispuestas en fascículos. Es un tumor de crecimiento relativamente lento dando metástasis por vía hemática y con bastante frecuencia colonizando los ganglios regionales, hecho a tener en cuenta para la conducta quirúrgica.

Abstract

Objective: To review a poorly studied pathology in the scientific literature., Material and Methods: An observational, longitudinal and ambispective study of a series of 51 intramuscular lipomas in 50 patients. The frequency distribution of qualitative variables, and the median and the interquartile range (IQR) for continuous variables were calculated. The relationship between the size of the lipomas (recoded into two values) and the study variables were analyzed using the Fisher exact test., Results: Men made up 62% of the series, and the median age was 61 years, with 55% of the total being overweight. About half of the patients were diagnosed in the upper limb. More than three-quarters (78%) were strictly intramuscular lipomas. Location, clinical and image presentation, treatment and results are described., Discussion: Intramuscular lipomas have their own particular characteristics. Nevertheless, MRI is sometimes unable to distinguish them from well differentiated liposarcomas. Using size as the only criterion for referring a patient with a soft tissue injury to a reference center is still debatable., Conclusions: Patients with intramuscular lipomas, although they may be typical in their presentation, especially when they are large and show findings that can be confused with a well-differentiated low grade liposarcoma, should be treated in experienced centers., (© 2013 SECOT.

Abstract

El tumor de células gigantes de partes blandas de bajo potencial de maligno, es una neoplasia poco frecuente, clasifica dentro de las lesiones fibrohistiocíticas. Histológicamente es un tumor con hallazgos idénticos al tumor de células gigantes del hueso. Presentamos un caso correspondiente a esta neoplasia. Se trató de paciente de 26 años con una lesión tumoral 20 cm x15 cm x15 cm, en ambas regiones lumbares y región sacra. El estudio histológico reveló una neoplasia con abundantes células gigantes, células fusiformes, hemosiderina y hueso metaplásico. Los estudios inmunohistoquímicos demostraron fuerte positividad de CD68 para las células osteoclásticas. La evolución del paciente fue favorable, sin evidencia de recidivas. Es imprescindible realizar el diagnóstico diferencial de este tumor con otras neoplasias con abundantes células gigantes, como el tumor de células gigantes de la vaina tendinosa y el fibrohistiocitoma maligno rico en células gigantes, el cual es un sarcoma de alto grado The giant cell tumor of soft tissues of low potential malignancy is a very rare tumor. It’s classified in fibrohistiocytic neoplasm and has features identical to giant cell tumor of bone. We present a clinical case for this less frequent malignancy. Patient 26 years old man with a tumor of 20 cm x 15 cm x 15 cm, in both lumbar and the sacral regions. Histological examination revealed a neoplasm with abundant giant cells, spindle cells, hemosiderin and metaplastic bone. The immunohistochemistry studies practice showed strong positivity of CD68 for the osteoclastic cells. The patient outcome was favorable, without evidence of recurrence. It is essential to make the differential diagnosis of this kind of tumor with other neoplasm with abundant giant cells, such as the giant cell tumor of the tendon sheath and malignant giant cell, also malignant fibrous hystiocitoma, which is rich in giant cells and high grade sarcoma
