Melanotic schwannoma (MS) is a rare variant of nerve sheath neoplasm that shows ultrastructural and immunophenotypical features of Schwann cells but also has cytoplasmic melanosomes and is reactive for melanocytic markers as well. Unlike conventional schwannoma, which is totally benign, MS has an unpredictable prognosis and is thought to have low-malignant potential. Herein, we present a rare case of recurrent MS in lumbar spine of a 59-year-old male.

Abstract PDF

We report a case of chondroblastoma arising in the lumbar spine in a 25-year-old man who presented with low back pain of 5 years duration. Plain radiography and computed tomography revealed a well-defined osteolytic mass surrounded by marginal sclerosis in the third lumbar vertebra. The mass encroached on the left neural foramen on magnetic resonance imaging. Histologically, the tumor consisted of round to oval cells with eosinophilic cytoplasm and randomly scattered osteoclastic type giant cells. There were characteristic chicken-wire calcification and aneurysmal bone cyst-like changes. Chondroblastomas of the lumbar spine are extremely rare, and only nine cases have been reported. Spinal chondroblastoma should be distinguished from other benign bone tumors, because it tends to show aggressive biological behavior with high recurrence and mortality rates.

Abstract PDF: A case of cervical chordoma diagnosed by fine needle aspiration is discussed. A 41year-old male was admitted due to dyspnea on neck flexion. Radiologic image revealed a retrotracheal superior mediastinal solid mass. Aspiration cytology showed many clusters of oval or large polygonal cells having abundant eosinophilic or bubbly cytoplasm in an amorphous blue-gray mucoid background. The nuclei were round and showed size variation, coarse granular chromatin, and indistinct nucleoli. Some cells contained brown granular pigments in the cytoplasm. Mitoses were rarely found. The cytoplasm was strongly positive for PAS stain. Immunohistochemical stains using cell block revealed positive reaction for cytokerain, EMA, vimentin, and S-100 protein. The confirmative diagnosis was made by following excisional biopsy. Electron microscopic study revealed large pools of intracytoplasmic glycogen and microfilaments. This is the first case of cervical chordoma diagnosed by aspiration cytology to our knowledge in Korean literature.

Abstract PDF: Pleomorphic xanthoastrocytoma is a rare tumor, presenting superficially over the cerebral hemispheres of young subjects. We report a case of Pleomorphic xanthoastrocytoma of the cervical cord in view of its unusual location. The patient is a 20-year-old female, presenting with left neck pain radiating to the left shoulder one month before the admission. Magnetic resonance imaging revealed a high signal lesion in the upper cervical cord lower brainstem in T2 weighted image. On operation, intramedullary tumor was present and it was relatively well delineated. Near-total removal of the spinal cord mass was done. Microscopically, the tumor was composed of pleomorphic astrocytes, which were spindle-shaped with cytoplasmic processes and hyperchromatic nuclei. Other cells were round with vesicular nuclei and abundant eosinophilic cytoplasm. A few giant cells were seen. Despite the marked pleomorphism, mitosis or necrosis was not encountered. Scattered foamy cells were also seen, which showed negative staining in GFAP immunostaining in contrast to other GFAP-positive tumors cells.

Abstract PDF: Neurosarcoidosis without systemic manifestation is vary unusual condition. Solitary lesion in the spinal dura is exceptional. The diagnosis of the neurosarcoidosis is very difficult, because the efficacy of Kveim test is low in neurosarcoidosis. The histologic examination is considered as confirmative diagnostic tool. The authors reported a case of neurosarcoidosis involving the dura of the cervical spine, in a fifty-nine year old female who had suffered from mid-back pain for six months and paraparesis for two weeks. There was a dumbbell shaped mass in the D4-5 dura. It showed tan gray color with rubbery consistency. With histological examination, it revealed diffuse non-caseating granuloma. Occasionally asteroid bodies were observed within the cytoplasm of the multinucleated giant cells. After operation, she was treated with steroid, and she has been well about nine month period.
