A patient with low back pain was found to have giant cell tumor of the ischium. After initial local radiation therapy, a hemipelvectomy was performed because of tumor progression.

We report a case of CD7+ stem cell lymphoma. A 47-year-old man presented with general malaise and lumbago in April 1997. The patient exhibited swollen left cervical lymph-nodes and an intra-abdominal bulky mass. He was referred to us because lymph-node biopsy specimens indicated a diagnosis of diffuse type malignant lymphoma. An abdominal CT scan disclosed large retroperitoneal, para-aortic, and mesenteric root masses. Bone marrow involvement was shown by bone marrow biopsy specimens, though no circulating blasts were detected at presentation. The patient was treated with high-dose CHOP therapy without any benefit. Though ESHAP therapy was performed as salvage chemotherapy, the abdominal masses did not shrink at all. The patient died of tumor progression in November 1997. In the terminal stage, the lymphoma cells emerged in the peripheral blood and thus became available for analysis. The cells expressed CD5, 7, 34, 38, 71, but were negative for CD1, 2, 3, 4, 8, 10, 13, 14, 16, 19, 20, 21, 25, HLA-DR, and EMA. An immunoglobulin heavy chain gene rearrangement band was detected by Southern blot analysis. However, no T cell receptor lambda or beta chain gene rearrangement bands were detected.

Spinal paragangliomas are extremely rare tumors, most frequently involving the cauda equina and the filum terminale. We aimed to investigate the clinical manifestations, radiological features, management, and follow-up data of primary spinal paraganglioma. We present the clinical data and long-term outcomes from a consecutive surgical series of 19 patients with pathologically diagnosed spinal paragangliomas. All of the patients had undergone surgical resection. Pre- and postoperative magnetic resonance imaging was performed and follow-up data and neurological functional assessment are presented and discussed. The mean age at diagnosis was 47.7 years, with a significant male predominance. The primary clinical symptoms were low back pain and sciatica. Magnetic resonance images (MRI) showed characteristic signs that help differentiate paragangliomas from other spinal tumors, including a "salt & pepper" sign, serpiginous flow void, and a peripheral hypointense rim. Also, a well-encapsulated appearance can be found intraoperatively. During a mean follow-up period of 62.1 months, remnant tumor progression was noted on MRI in three patients with incomplete resection. Pain symptoms were relieved immediately after surgical intervention, while motor and sphincter dysfunction were much slower to improve. Differential diagnosis of paraganglioma based on MR images alone is challenging, but the presence of specific characteristic features provides suggestive clues; however, accurate diagnosis depends on pathological criteria. Despite the benign course, gross total resection is ideal, given an increased risk of recurrence in situ. Timely recognition and surgical treatment should be emphasized to avoid progressive neurological deficits.

Small cell lung cancer (SCLC) is common in thoracic neoplasms, with a high degree of malignancy and rapid tumor progression. SCLC is often diagnosed with widespread metastases at the time of the initial diagnosis. A small proportion of late-stage SCLC patients are in a poor physical condition and exhibit disqualifying chemoradiotherapy indications. The present study reports the case of a patient who presented with lumbago and backache. Following physical examination, computed tomography, bronchoscopy and biopsy, the patient was diagnosed with SCLC with an Eastern Cooperative Oncology Group score of <2. One cycle of chemotherapy was administered whilst ventilator support was provided, and the patient's condition eventually improved. However, the patient finally succumbed to respiratory failure at 10 months post-diagnosis.
