In the present study, the case of a patient with nodular sclerosing Hodgkin's lymphoma (NSHL) presenting with diffuse fibrosis of the bone marrow (BM) was reported. A 30-year-old male complained of fever for 1 year, as well as lumbago, lymph node swelling and night sweats for 3 months. A biopsy of the lymph nodes established a diagnosis of NSHL. Aspiration of BM was a dry tap, and the BM biopsy demonstrated marked myelofibrosis with increased proliferation of reticulin fiber. Multiple skeletal lesions were detected in the patient's vertebra, pelvis, sternum and bilateral femur by magnetic resonance imaging and computed tomography. Following numerous courses of chemotherapy and radiotherapy, remission of the lymphoma was achieved. Subsequently, the BM aspiration became possible, and BM biopsy demonstrated a reduction in fibrosis.

Osteoid osteoma is a benign primary bone tumor of unknown etiology that occurs most commonly in males during adolescence and early adulthood. Osteoid osteoma affects the spine in 20% of cases, and may cause spinal deformity, stiffness, and pain that may sometimes be worst at night. We present a novel description of a partial laminectomy with cement augmentation after resection of an osteoid osteoma. A 22-year-old male with a past medical history of Hodgkin's lymphoma status post chemotherapy and radiation to the mediastinum, and right hip osteoblastoma treated with surgery and radiofrequency ablation presented with low back pain for five years with a recent onset of severe radicular symptoms. The pain was described as shooting and radiating laterally down the right leg to the mid-calf without bowel or bladder incontinence. He has a known right L5 laminar sclerotic lesion measuring 11 x 10 mm causing neuroforaminal narrowing and it kept increasing in size despite previous treatment with stereotactic radiosurgery and radiofrequency ablation. This lesion was metabolically active on positron emission tomography-computed tomography (PET-CT) imaging. His pain was worsening and was refractory to physical therapy, non-steroidal anti-inflammatory drugs (NSAIDs), aspirin, and radiation therapy. A right L5 partial laminectomy was performed to resect the abnormality in an en-bloc fashion. The lesion did not involve the inner cortex of the bone. Lamina reconstruction was achieved with bone cement augmentation for the preservation of vertebral column strength. Pathology was consistent with osteoid osteoma with marrow edema. Microscopic findings include bony trabeculae associated with prominent rimming and hypercellular fibroblastic stroma. No nuclear atypia, necrosis or appreciable mitotic activity was observed. The patient remains neurologically intact with significantly improved radicular symptoms and low back pain. Osteoid osteoma of the lamina may be resected using a partial laminectomy and cement augmentation done to preserve the integrity of the posterior ligamentous complex, prevent potential fracture of the pars interarticularis, and avoid the need for lumbar fusion in younger patients in whom this pathology is commonly found.

Anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin lymphoma (NHL) originated from mature post thymic T cells. They represent 1-3% of NHL. Different subtypes have been described: Anaplastic lymphoma kinase (ALK)-negative ALCL, ALK-positive ALCL and breast implant-associated ALCL. ALK-positive ALCL affects mainly the young and has better prognosis. We present a case report of an adult woman with AKL-positive ALCL, diagnosed by endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA). A 59-year-old women with no history of breast implants, was admitted for a four-month low back pain. Initially, the patient was treated for a spondyloarthropathy, but due to persistence of the symptoms, a lumbosacral MRI was performed, showing changes in morphology and signal intensity in the vertebral body of L3, along with edema and a paravertebral collection that affected the left psoas muscle, suggesting granulomatous spondylodiscitis. Chest CT-scan showed mild left pleural effusion, subcarinal and right hiliar adenomegalies. An EBUS-TBNA with ROSE (rapid on-site evaluation) was performed showing positive findings for malignancy, suggestive of hematolymphoid neoplasia. Pathology analysis showed an AKL-positive ALCL. Additionally, a biopsy of paravertebral tissue biopsy was obtained, which was consistent with the nodal sample. Chemotherapy was initiated with the CHOP protocol: cyclophosphamide, hydroxydaunorubicin, vincristine sulfate and prednisone. EBUS-TBNA is a minimally invasive and safe technique for obtaining mediastinal samples. Collaboration with a cytopathologist trained to perform ROSE improves the diagnostic performance.
