Introduction: Primary angiosarcoma of the breast is an uncommon subtype of soft-tissue sarcoma known to be aggressive and is associated with distant metastasis and poor prognosis. Solitary bone metastases occurring in these cases are even more rare with the available limited literature based from small retrospective case series.
Case Report: We present a case of a 24-year-old Filipino female previously diagnosed with primary angiosarcoma of the bilateral breasts, initially presenting with a 3-month history of the right hip pain and consulted due to a pathologic fracture of the right proximal femur. Diagnostic tests done confirmed solitary skeletal metastasis to this area, for which she underwent wide resection and application of a proximal femoral endoprosthesis. Postoperatively, the patient was able to independently ambulate, with follow-up radiographs showing stable implant fixation. Further imaging showed that lesion-free bones, however, noted development of distant recurrence manifesting with pulmonary metastases and hemorrhagic subcutaneous lesions 3 months after. Adequate tumor resection and radiotherapy are reported to successfully treat isolated skeletal metastasis in the proximal femur. The presence of the pathologic fracture before definitive treatment may have contributed to its distant recurrence, in addition to an already aggressive nature of the primary malignancy.
Conclusion: In the background of primary breast angiosarcoma, although rare, high suspicion for isolated skeletal metastasis in a symptomatic patient prevents delay in definitive management, which avoids progression to a poorer prognosis.
Keywords: Solitary bone metastasis, angiosarcoma, proximal femur, pathologic fracture.

Introduction: Giant-cell tumor (GCT) of bone is a benign tumor, however locally aggressive with a tendency for local recurrence and potential for metastasis. The distal radio is the third most frequent location, after the distal femur and proximal tibia. In Campanacci grade Grade III tumors, multiple reconstruction techniques after resection of the distal radius have been described, such as bone graft plus wrist arthrodesis. The use of the drug denosumab in the pre-operative period helps a surgery with less comorbidity, and limb preservation and reduces the chance of function loss. The objective is to report a case of a patient who underwent treatment of Campanacci grade Grade III distal radius bone GCT, with pre-operative denosumab application and resection surgery, replacement by bone graft (distal ulna), and ulnocarpal arthrodesis.
Methodology: Quantitative, descriptive, retrospective study by analyzing the medical record of a case report, plus literature study.
Conclusion: The use of pre-operative denosumab favors surgery with less comorbidity, ; however, more studies are needed in order to define the ideal dosage. Ulnar translocation with ulnar carpal arthrodesis has also proved to be a successful technique and further studies are needed to evaluate its effectiveness.

Schwannoma in the Bifurcation of the Sciatic Nerve: A Case Report and Literature Review

Purpose: The schwannoma is a benign tumor and is known to be the most common type of tumor of the peripheral nerve sheath. They are known to arise from the nerves of the head and neck; however, outside this region, it is found more often in the upper extremity, and if occurring in the lower extremity, is likely found in the posterior tibial nerve. Schwannoma of the sciatic nerve is considered a very rare entity, accounting for only 1% of all schwannomas, with an estimated incidence of about 6 cases per million individuals.
Methods: In our literature search, it is noted that they are more likely to arise from the proximal aspect of the nerve, as it exits the sciatic notch, presenting as a mass in the proximal thigh. This case reports tackles an even more unusual presentation of this tumor, occurring adjacent to the bifurcation of the sciatic nerve.
Results: A 46-year- old male presented with sharp, shooting pain from the back of his thigh to the plantar aspect of his left foot of 2 years duration. Patient was initially diagnosed as a case of plantar fasciitis and hamstring tightness that was managed conservatively. However, due to persistence as well as appearance of a small mass on the posterior thigh and positive Tinel’s sign over the mass, patient underwent work-up and subsequent surgery.
Conclusion: Due to its presentation that closely mimics sciatica of a lumbosacral discal pathology and other musculoskeletal disorders, these are often diagnosed and managed late. Despite its rarity, it should be suspected in patients with history of radicular pain without any neurologic deficits, which is poorly controlled by analgesics and supportive therapy, with physical examination pointing to a localized neural pathology.

Introduction: Lipoblastomas are a rare type of benign neoplasm arising from embryonal fat, found primarily among young children. Predominantly small tumors of the head and neck, trunk, and extremities, less than twenty 20 cases of gluteal lipoblastoma have been reported in the English literature. Complete surgical resection is recommended, with recurrence rates at 14–-46%.
Case Report: A one1-year-old female presented with a large, painless gluteal mass of one 1 year. Growth was consistent since shortly after birth, with no history of manipulation, constitutional symptoms or trauma. Magnetic resonance imaging showed a heterogenous, encapsulated, lobulated mass without bone or vascular invasion, and marginal excision was completed without need for soft soft-tissue reconstruction. At five 5 years post-surgery, the outcome has been uneventful, without evidence of recurrence.
Conclusion: Lipoblastomas present with characteristic features on clinical examination, diagnostic imaging, and histology. While benign, they may share features with more aggressive soft tissue tumors, emphasizing the need for careful assessment prior to before surgery.

Introduction: Renal cell carcinoma (RCC) is the most common malignant kidney tumor, commonly metastasizing to the lung, lymph nodes, bones, and brain. Here, we present a rare case of renal cell skeletal muscle metastases (SMMs), accounting for only <1% of all RCC metastases.
Methods: This is a descriptive report on the clinical course, diagnostic investigations, and surgical treatment of a case of SMM in a patient previously diagnosed with RCC.
Results: This is a 58-year-old male who previously underwent radical nephrectomy for RCC, presenting with a 5-month history of a rapidly enlarging left gluteal mass. The mass was confirmed to be renal clear cell metastasis through percutaneous biopsy. On magnetic resonance imaging, two heterogeneously enhancing lesions in the left gluteal muscle and right paralumbar muscles at the level of L4 and L5 were noted. Positron emitted tomography scan confirmed no other metastases. He underwent wide excision of the right paraspinal mass and buttockectomy for the left gluteal mass.
Conclusion: SMM in RCC is rare, thus tissue diagnosis and imaging is deemed necessary to rule out any other primary sarcoma. In these cases, patients may benefit from metastasectomy. Regular follow-up and surveillance are recommended for these patients to rule out recurrence.
Keywords: Renal cell carcinoma, metastases, extraskeletal, buttockectomy.
