We report a case of intracranial chondrosarcoma of the skull base with fatal intra- and peritumoral hemorrhage. A 75-year-old woman complained of right blepharoptosis and diplopia in 1989. An initial diagnosis of Tolosa-Hunt syndrome was made, and the patient was treated with steroid hormone therapy at a local hospital. Because the symptoms had not been relieved, she was admitted to our hospital. Computed tomography (CT) scan and magnetic resonance (MR) images demonstrated a large mass extending from the right side of the clivus to the parasellar region and petrous apex. The mass was partially calcified and had destroyed the base of the middle cranial fossa. The lesion had homogeneous enhancement with contrast medium. Preoperative diagnosis was chordoma or chondroma. A biopsy of the tumor was made. The pathological diagnosis of biopsy specimen was chondroid chordoma. The patient was followed up but no palliative treatment such as radiotherapy was given. On June 25, 1991, she suffered from cerebral infarction. On June 29, 1993, she died of sudden respiratory failure. Autopsy was performed. It revealed intra- and peritumoral hematoma compressing the medulla oblongata, pons and midbrain. Histologically immature chondroid cells proliferated in a myxoid-rich extracellular matrix. The tumor cells were composed of hyperchromatic nuclei and eosinophilic cytoplasm, but there was no evidence of notochordal differentiation. Compared with biopsy findings, the tumor showed high cellular density. Immunohistochemically, the tumor cells reacted positively for S - 100 protein, vimentin and cytokeratin, but negatively for epithelial membrane antigen (EMA) and carcinoembryonic antigen (CEA). In view of these histopathological findings, the diagnosis of low-grade myxoid chondrosarcoma was established. Intratumoral hemorrhage often occurs in malignant brain tumors such as glioblastoma and metastatic brain tumor, but chondroid tumors rarely develop a fatal type of intratumoral hemorrhage. Only 8 cases have been reported in detail to date. We discuss the immunohistochemical features and spontaneous intratumoral hemorrhage of chondrosarcoma.

An autopsy case of small cell glioblastoma, showing multiple extracranial metastases, is reported with special reference to histopathological differentiation from metastatic small cell carcinoma. Widely spread lesions in the bilateral lungs were developed after an operation and chemo-radiotherapy for glioblastoma, and the lung lesions led to fatal respiratory failure. Postmortem examination revealed multiple tumors in the lung, lymph nodes, and the heart, as well as local invasion of the primary tumor to the dura, skull, and the scalp. The mechanism of extracranial metastasis of brain tumor is discussed.

A case of gliosarcoma composed of glioblastoma and liposarcoma is presented. A 70-year-old Japanese man was admitted to hospital because of dysarthria and aphasia. Magnetic resonance imaging indicated a brain tumor located in the temporal-parietal area of the left hemisphere. He rejected any therapy and died of respiratory failure. At autopsy the tumor was well-demarcated with firm consistency and myxoid appearance, accompanied by necrosis and hemorrhage. Microscopically the tumor consisted of both glial and sarcomatous components, compatible with a gliosarcoma. Lipoblast-like tumor cells were identified in the sarcomatous area. Glial component was observed in the periphery and was diffusely positive for CD56 and S100 protein and focally for glial fibrillary acidic protein. Only a small number of tumor cells in the sarcomatous area expressed neurogenic markers. Lipoblast-like tumor cells were positive for S100 protein but negative for any other neurogenic markers. A significant number of tumor cells were positive for retinoblastoma protein (pRB) in the glial area, whereas only a few of them were positive in the sarcomatous area, indicating alteration of pRB in sarcomatous component. The present tumor is a rare gliosarcoma with liposarcomatous differentiation; alteration of pRB may play a role in sarcomatous transformation of glial component.

A 65-year-old woman presented with progressive gait disturbance. She complained of appetite loss for 3 months. Her gait gradually became unsteady, and she was admitted to our hospital. On admission, slow mentation, bathyhypesthesia in left upper and both lower extremites, positive Romberg sign and wide-based gait were observed. Gd-enhanced MRI revealed mass lesions in the left temporal fossa and the cervical spinal canal with focal meningeal enhancement. Besides lesions in the central nervous system (CNS), systematic examination detected no additional malignancy. Repeated cytology of the cerebrospinal fluid was negative. After admission, her consciousness became reduced gradually. At 2 months after admission, she died of central respiratory failure. On autopsy, diffuse extension of the tumor cells was observed on the surface of CNS, and the mass lesions observed by MRI were extra-parenchymal On microscopic examination, the mass was consisted of GFAP positive malignant cells, and included perivascular pseudorosette, pseudopalisading necrosis and many mitotic cells. The diagnosis of the case was made as primary diffuse leptomeningeal gliomatosis (PDLG). PDLG is a rare disorder that is difficult to diagnose by CSF cytology. The progress of PDLG is rapid, and appropriate treatment is rarely taken. However, the combination of temozolomide and the radiotherapy performed for a glioblastoma has been reported as a possible treatment for PDLG. We emphasize that, in possible cases of PDLG, a biopsy should be performed in the early stages, especially in cases showing features similar to those of metastatic meningeal carcinomatosis and have no malignant tumors by whole body examination.

This report presents the case of a 67-year-old woman affected by glioblastoma. After a few days of adjuvant therapy with temozolomide and prophylaxis with trimetrophin-sulfamethoxazolo to prevent Pneumocystis Jiroveci, she had progressive and rapid worsening of symptoms with weakness, dyspnea and orthopnea. She had peripheral edema and proximal hyposthenia of the lower limbs. Chest CT showed bilateral ground-glass opacities and laboratory exams revealed hypoxemia and hypocapnia, an initial reduction in platelet and white blood cells, and an elevation of LDH, AST, ALT, and active urinary sediment. Blood cultures, bronchoalveolar lavage (BAL) data and transbronchial biopsy showed no infections, and in particular no evidence of Pneumocystis Jiroveci pneumonia. Histological examination revealed a typical pattern of AIP. She was treated with broad-spectrum antibiotics and high-dose steroids. The symptoms worsened and respiratory failure required mechanical ventilation. The pneumonia was not responsive to medical or invasive care. She died after ten days of hospitalization. At present very little can be found in the literature about lung toxicity caused by temozolomide. This case can be added as a new report describing this risk. The combination therapy with temozolamide and trimetophin-sulfamethoxazolo could have a synergistic action inducing various forms of pulmonary toxicity. ESTABLISHED FACTS: Acute interstitial pneumonia is a common manifestation of lung toxicity caused by drugs. The clinical course is favorable with a good response to corticosteroids. NOVEL INSIGHT: This is the first fatal case of lung toxicity caused by Temozolomide. Clinicians must be aware that a combination therapy including trimetophin-sulfamethoxazolo could have a synergistic action in inducing pulmonary toxicity.
