Summary
Systemic lupus erythematosus can cause myelofibrosis, a condition not solely linked to blood cancers. This case highlights bone lesions and extramedullary hematopoiesis in a lupus patient with myelofibrosis.
Area of Science:
- Hematology
- Rheumatology
- Oncology
Background:
- Myelofibrosis is a bone marrow disorder characterized by fibrosis, often associated with hematologic malignancies.
- Non-malignant causes of myelofibrosis are recognized, including autoimmune conditions.
- Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse clinical manifestations.
Observation:
- A 44-year-old woman presented with bone lytic lesions.
- The patient was diagnosed with myelofibrosis.
- Extramedullary hematopoiesis was identified in the setting of myelofibrosis.
Findings:
- The patient's myelofibrosis was associated with systemic lupus erythematosus, an autoimmune disease.
- This case demonstrates a rare presentation of myelofibrosis linked to SLE, presenting with bone lytic lesions and extramedullary hematopoiesis.
Implications:
- Highlights the importance of considering autoimmune diseases, such as SLE, in the differential diagnosis of myelofibrosis, especially in the absence of hematologic malignancy.
- Suggests that SLE can manifest with significant bone pathology and extramedullary hematopoiesis in the context of myelofibrosis.
- Underscores the need for comprehensive etiological workup in patients with myelofibrosis to identify underlying non-malignant causes.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
