Tratamiento multidisciplinario de condrosarcoma gigante de fémur proximal mediante hemipelvectomía externa y reconstrucción con colgajo pediculado tipo fillet flap: presentación de un caso clínico / Multidisciplinary treatment of giant chondrosarcoma of the proximal femur by external hemipelvectomy and reconstruction with a pedunculated fillet flap: presentation of a clinical case / Tratamento multidisciplinar do condrossarcoma gigante do fêmur proximal por hemipelvectomia externa e reconstrução com retalho fillet flap: apresentação de um caso clínico

El condrosarcoma forma parte de los tumores primarios malignos más frecuentes. Las localizaciones pélvicas y de raíz de muslo requerirán abordajes amplios con la consecuente dificultad de cobertura de partes blandas. La hemipelvectomía externa es habitualmente el procedimiento de elección para estas localizaciones. Implica la resección de la extremidad inferior en bloque asociada a la hemipelvis ipsilateral, dando como resultado un gran defecto de cobertura. En algunas circunstancias, la extensa resección de partes blandas hace imposible la utilización de colgajos rotacionales locales. La reconstrucción con colgajo tipo "Fillet flaps" ofrece a estos defectos de partes blandas la opción de lograr una adecuada cobertura. El objetivo del trabajo es mostrar la resolución de un caso poco convencional de condrosarcoma de fémur proximal y su reconstrucción de partes blandas con un método nunca antes utilizado en nuestro medio.

Chondrosarcoma is one of the most frequent malignant primary tumors. Pelvic and proximal femur locations require extensive approaches with the consequent difficulty of soft tissue reconstruction. External hemipelvectomy is usually the procedure for these locations. It involves total en bloc resection of the lower extremity associated with ipsilateral hemipelvis, resulting in a large coverage defect. In some cases, local rotational flaps are impossible. Reconstruction with fillet flaps offers an adequate coverage for soft tissue defects. The objective of this study is to show the resolution of an unconventional case of chondrosarcoma of the proximal femur and its soft tissue reconstruction with a method never before used in our country.

Bilateral femur metastasis in endometrial adenocarcinoma

Bone metastasis of endometrial carcinoma is uncommon, and bilateral femur metastasis is extremely rare. A 48-year-old woman with Federation International of Gynecology and Obstetrics stage IIB grade 2-3 endometrial adenocarcinoma underwent curative radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic and para-aortic lymphadenectomy followed by radiotherapy and chemotherapy. Twenty-two months after surgery, she suffered from progressive pain and then presented bilateral femur metastasis. She was administered the surgical excision of bony metastasis and adjuvant therapies including chemotherapy, palliative radiation, and hormone therapy. Three and a half years after treatment of bony metastasis, she remains clinically well. Bone metastasis of endometrial carcinoma may occur at some unusual sites, and bilateral femur metastasis should be considered in patients. Multimodal therapies are usually advocated for bone metastasis of endometrial carcinoma

Painless subtrochanteric osteoid osteoma presenting with lengthened femur A case report

An 11-year-old boy suffered from limb length discrepancy. He had limitation of the last degrees of flexion and external rotation of the left hip with wasting of the muscles of the thigh. The left lower limb was found 2 cm longer than the normal right side. There was a painless osteoid osteoma in the subtrochanteric region of the left femur
