A twenty-five-year-old female was admitted with lower right abdominal pain, right coxalgia and an inability to extend her right inferior limb. She had a history of tuberculosis pleurisy two years before. Abdominal ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a right retroperitoneal mass which was suspected to be an abscess or tumor. Percutaneous aspiration of the mass was followed by the administration (p.o.) of antituberculosis drugs (pyrazinamide, ethanbutol, isoniazide, refampicin). One month after initial drainage, the tube was removed but intra-cystic fluid collection was still visible a month later using CT and MRI. Therefore, a second percutaneous aspiration was followed by the instillation of streptomycin and minocycline hydrochloride. Six months after employing this therapy, no fluid collection was found.

Particle disease is a rare lesion that results from an inflammatory response due to wear debris-induced osteolysis following arthroplasty. Particles resulting from the wear debris cause macrophage activation and phagocytosis. Particle disease often leads to joint loosening and implant failure. Radiologically, it often results in a well-defined osteolytic lesion-mimicking tumor. A 68-year-old man who presented with chronic hip pain following total hip replacement was studied by fine-needle aspiration. An ultrasound-guided aspiration revealed hypercellular smears consisting predominantly of proliferating mesenchymal cells, foamy macrophages, inflammatory cells, and background acellular debris. Numerous multinucleated giant cells were observed as well. Differential diagnosis includes primary or metastatic clear-cell tumors.

A 4-year old history of left hip pain brought a 41-year-old women to the surgery clinic where an osteoblastic tumor in the ileum and a thyroid nodule were diagnosed. Incisional biopsy of the ileal lesion showed a metastatic carcinoma, possibly with neuroendocrine differentiation. The thyroid nodule was a follicular carcinoma with progression to insular carcinoma. In retrospect the histologic aspect of the ileal metastasis was identical to that of the insular areas in the thyroid carcinoma. In summary, a patient is described with an osteoblastic metastasis, derived from the insular component of a dedifferentiated follicular carcinoma of the thyroid.

Localized Langerhans cell histiocytosis (LCH) of bone often presents as a diagnostic challenge. Magnetic resonance imaging (MRI) is frequently used to better delineate most solitary bony lesions. The authors present two cases that illustrate and better define the role of MRI in the evaluation of solitary bone lesions of LCH. In a 3-year-old boy with left-sided hip pain, MRI showed a focal lesion involving the proximal left femur with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. A tumor was suspected because of the overall imaging characteristics and increased uptake on three-phase nuclear scintigraphy. In a 6-year-old boy with right thigh pain, MRI showed a fluid-containing lesion in the mid-diaphysis of the right femur, suggestive of chronic osteomyelitis and Brodie abscess. MRI was instrumental in showing the extent of the lesions in both cases; however, the final diagnosis of LCH was achieved only with histopathologic confirmation, illustrating the limited diagnostic power of this imaging tool.

The patient was a 64-year-old female who underwent an abdomino-perineal resection for advanced lower rectal carcinoma. The tumor was a mucinous adenocarcinoma, type 2 in the Japanese classification of colorectal carcinoma, and was measured 4.5 cm in size. Histologically, the tumor was considered to be stage II (a2, n1, P0, H0). She received adjuvant chemotherapy with 5-FU/LV. After 7 months from the surgery, the patient developed a hip pain. Pelvic CT scan revealed a 4.5 x 6.0 cm mass anterior to the sacrum. Consequently, a diagnosis of local recurrence with sacrum invasion was made. An operation, involving tissue expander placement in the pelvis and pelvic floor was made by dexon mesh, was performed. Radiotherapy was given to the pelvic region at a total dose of 65 Gy (given 2.5 or 3 Gy each x 25 fragments). Chemotherapy with CPT-11 (100 mg/body) and 5'-DFUR (800 mg/body) was administered for 3 cycles. CEA (ng/ml) was decreased within a normal range from maximum 13.8. No progression was detected on CT, and Hip pain had disappeared. Abscess in the pelvis by tumor necrosis was managed conservatively. In this case, tumor marker is within a normal range over 2 years and QOL was improved, suggesting that chemoradiation with a tissue expander may be effective.

Fibrocartilaginous dysplasia is a variant of fibrous dysplasia in which extensive cartilaginous differentiation is identified. The amount of cartilage varies from case to case, however, no percentage has been proposed to consider this diagnosis. We present a 6-year-old girl with a two-year history of hip pain. Initial imaging studies of the right femur revealed a lucent lesion of the proximal shaft that extended into the femoral neck with ill-defined borders but well maintained cortex. Computed tomography scan demonstrated increased density of the medullary cavity but the cortex appeared intact. Curettage of the lesion was performed and fragments with cartilaginous appearance were obtained, weighing 45 g in total. Microscopically, the tumor revealed a cartilaginous (60%) and a fibro-osseous (40%) component; the former had increased cellularity and some chondrocytes displayed moderate atypia and binucleation, while the latter showed features of fibrous dysplasia. Areas of endochondral ossification and calcification were also identified. After five years of surgery this child is well and without evidence of recurrence. We discuss the differential diagnosis of this variant of fibrous dysplasia in the pediatric group.

The patient was a 55-year-old female who underwent an abdomino-perineal resection for advanced lower rectal cancer. The tumor was a well differentiated adenocarcinoma, type 2 in the Japanese classification of colorectal carcinoma, and was measured 2.3 cm in size. Histologically, the tumor was considered to be stage IIIb (mp, n3(+), P0, H0, M(-)). She received adjuvant chemotherapy with 5'-DFUR. After 13 months from the surgery, the patient developed a hip pain. After 16 months from the surgery, a pelvic MRI scan revealed a 3 cm tumor in the perineum. Biopsy from the tumor revealed adenocarcinoma. Consequently, we diagnosed local recurrence in the perineum. Chemotherapy with CPT-11 (230 mg/body) and 5'-DFUR (800 mg/body) was administered for 2 cycles. Because the tumor was enlarged, high-dose rate interstitial brachytherapy was given to the recurrent site at a total dose of 54 Gy/9 fractions/5 days. There were no severe complications. CEA was decreased within normal range from a maximum of 9.3. No progress was detected on CT and MRI, and the hip pain had disappeared. The tumor marker is within normal range for about 2 years and QOL was improved. Hence, high dose rate interstitial brachytherapy appears to be effective for locally recurrent rectal cancer.

In this case report, we describe the first account in the literature of a patient who presented with extramedullary myeloid sarcomas (EMS) and Ph+ AML without leukemic manifestations. EMS are rare, destructive, extramedullary tumor masses that consist of immature leukemia cells. These tumors can occur anywhere in the body and have to be differentiated from lymphoma, carcinoma or infectious processes. We report a previously healthy 61-year-old male who presented with progressive left-sided hip pain. Magnetic resonance imaging (MRI) of the left hip joint revealed an extensive lytic lesion with pathological fracture of the femur. The lesion was confirmed by biopsy to be EMS with bcr-abl rearrangement in tumor cell nuclei by fluorescence in situ hybridization (FISH). Laboratory tests showed normal metabolic and complete blood counts with normal differential. Peripheral blood RT-PCR for bcr-abl was negative. Bone marrow examination revealed a normocellular with progressive trilineage hematopoiesis and no evidence of increased blast count. On the basis of available literature for the treatment of EMS, our patient received standard AML induction chemotherapy consisting of idarabucin and cytarabine. After cytogenetics studies of the bone marrow revealed bcr-abl rearrangement, we discontinued further chemotherapy and managed the patient with imatinib mesylate 400mg p.o.q. day. Follow-up at time of manuscript preparation, the patient remains in complete cytogenetic remission (CCR) for 22 months. To the best of our knowledge, this is the first case report of Ph+ AML presenting as a primary EMS without leukemic manifestations.

A 60-year-old Japanese man presented to our hospital with a painful left hip. Computed tomography showed a tumor in the left kidney and metastases in the left gluteus maximus muscle and lung. The pathological diagnosis of a biopsy specimen obtained from a metastatic lesion in the left gluteus maximus muscle was sarcomatoid renal cell carcinoma. On admission, his general condition was extremely poor. He was confined to bed because of severe left hip pain and confusion, possibly caused by hypercalcemia. This seriously ill patient suffering from advanced sarcomatoid renal cell carcinoma was treated with single-agent gemcitabine, resulting in symptom relief and a dramatic improvement in his status; all of the tumors had regressed significantly by the 11th dose of gemcitabine. These findings indicate that single-agent gemcitabine is one of the few chemotherapeutic agents effective for palliation in patients with sarcomatoid renal cell carcinoma, even those with poor performance status.
