Article Abstract
Background: Chondrosarcoma of the foot is a rare malignant bone tumour, and it is even rarer when it originates in a toe bone. Surgical excision is the only effective treatment. The osteolytic destruction of the tumour severely affects limb function and carries the risk of distant metastasis. Most such tumours are removed surgically to minimize local recurrence and distant metastases, maximize limb function, and prolong the patient's tumour-free survival time. The main objective of this article is to present the case of a chondrosarcoma that invaded the first phalanx of the left foot and formed a large phalangeal mass with osteolytic destruction of the distal bone.
Case Summary: A 74-year-old man suffered from swelling of his left toe for six months, with pain and swelling for two months. Computed tomography and magnetic resonance imaging showed that the tumour on the first phalanx of the left foot was approximately 54.9 mm × 44.6 mm, surrounded by a significant soft tissue signal mass, with osteolytic destruction of the distal phalanx and a speckled bone-like high-density shadow within it.
Conclusion: Chondrosarcoma occurring in a toe bone is extremely rare. In this case, extensive surgical resection of the large low-grade chondrosarcoma, which showed osteolytic destruction and invaded the distal metatarsal bone, was safe and effective.

Introduction: Low-grade myofibroblastic sarcoma (LGMS) is an atypical and extremely infrequent type of tumor, primary mass being usually present in subcutaneous and soft tissue. Bony involvement is very rare. It has a very high chance of recurrence locally due to its aggressive biological behavior, metastasis in other parts of body is rarely seen.

Multiple myeloma (MM) is a plasma cell malignancy characterized by clonal proliferation in the bone marrow (BM). Previously, it was reported that G‑protein‑coupled receptor 4 (LGR4) contributed to early hematopoiesis and was associated with poor prognosis in patients with MM. However, the mechanism of cell homing and migration, which is critical for MM progression, remains unclear.

Bone is a common and debilitating site for metastatic cancer cell expansion. Skeletal metastasis is a multistage process, with primary stages of circulating tumour cells, progressing to a dormant state in vasculature and bone marrow niches, followed by tumourigenic reactivation, proliferation and finally bone destruction. The frequency of bone metastasis is reconciled in Paget's 'seed and soil' hypothesis, where a conducive microenvironment (bone niche) is essential for cancer cell colonisation.

Introduction: A Giant Cell Tumor (GCT) of the bone is a locally osteolytic tumor made up of mononuclear ovoid stromal cells and multinucleated giant cells. It commonly affects long bones like the distal femur and proximal tibia, but can also develop in the cervical spine during the third and fourth decades of life.

Multiple myeloma (MM) is a clonal plasma cell proliferative malignancy characterized by a debilitating bone disease. Osteolytic destruction, a hallmark of MM, is driven by increased osteoclast number and exacerbated bone resorption, primarily fueled by the excessive production of RANKL, the master regulator of osteoclast formation, within the tumor niche. We previously reported that osteocytes, the most abundant cells in the bone niche, promote tumor progression and support MM bone disease by overproducing RANKL.
