Testicular seminoma after the complete remission of extragonadal yolk sac tumor : a case reportIsao Kuroda
Department of Urology, Saitama Medical School, Moroyama, Saitama, Japan
BMC Urol 4:13. 2004..A testicular biopsy may thus be highly advisable when evaluating an extragonadal germ cell tumor...- Multicentric contiguous variant of epithelioid angiosarcoma of the bone. A rare variant showing angiotropic spreadTomoko Mitsuhashi
Department of Pathology, Saitama Medical School, Saitama, 350 0495, Japan
Ann Diagn Pathol 9:33-7. 2005..Multicentric epithelioid angiosarcoma of the bone is a pitfall in pathological diagnoses, especially if a strong radiological impression of metastatic carcinoma is provided. Therefore, pathologists should be aware of this rare variant... - KIT-negative undifferentiated endometrial sarcoma with the amplified epidermal growth factor receptor gene showing a temporary response to imatinib mesylateTomoko Mitsuhashi
Department of Pathology, Saitama Medical School, Saitama 350 0495, Japan
Ann Diagn Pathol 11:49-54. 2007..The amplified EGFR in UES has not been reported previously, and further studies are necessary to consider the possibility of EGFR-targeted therapy in such sarcomas... - Post-gastric endoscopic mucosal resection surveillance biopsies: evaluation of mucosal changes and recognition of potential mimics of residual adenocarcinomaTomoko Mitsuhashi
Department of Pathology, Saitama Medical School, Saitama, Japan
Am J Surg Pathol 30:650-6. 2006..Mimics of residual adenocarcinoma, namely clear cell degeneration and signet-ring cell-like change should be judiciously assessed to avoid unnecessary surgery... - Squamous cell carcinoma of the skin: dual differentiations to rare basosquamous and spindle cell variantsTomoko Mitsuhashi
Department of Pathology, Saitama Medical School, Iruma-gun, Saitama, Japan
J Cutan Pathol 33:246-52. 2006..Epithelial membrane antigen was focally positive in the conventional SCC area. To our knowledge, this is the first case report of SCC of the skin that has dual differentiations to BSC and SCSC... - Anaplastic oligodendroglioma: a case report with characteristic cytologic features, including minigemistocytesTomoko Mitsuhashi
Department of Pathology, Saitama Medical School, Saitama, Japan
Acta Cytol 51:657-60. 2007..Absolute criteria for grading oligodendrogliomas are somewhat poorly defined in contrast to those for grading astrocytic tumors, and cytologic features of anaplastic oligodendrogliomas have been poorly described... - Immunohistochemical evaluation of KIT expression in sarcomas of the gynecologic regionMasato Nakayama
Department of Pathology, Saitama Medical School, Saitama, Japan
Int J Gynecol Pathol 25:70-6. 2006..However, none of the cases showed c-kit aberrations in exons 9, 11, 13, and 17. Judicious decision is mandatory before applying Imatinib therapy to KIT-positive gynecologic tumors... - Cutaneous reactive angiomatosis occurring in erythema ab igne can cause atypia in endothelial cells: potential mimic of malignant vascular neoplasmTomoko Mitsuhashi
Department of Pathology, Saitama Medical School, Saitama, Japan
Pathol Int 55:431-5. 2005..The aforementioned changes may be confused with malignant vascular neoplasm because of unusual cytological atypia and atypical mitoses in the endothelial cells... - Multiple organ involvement in eosinophilic polymyositis: an autopsy reportKeisuke Ishizawa
Department of Pathology, Saitama Medical School, Japan
Hum Pathol 37:231-5. 2006..These results indicate that the overrun of eosinophils underlying eosinophilic polymyositis, regardless of the presence of hypereosinophilic syndrome or other systemic disorders, could involve wide-ranging visceral organs... - Pathological evaluation of uterine leiomyomas treated with gonadotropin-releasing hormone agonist (GnRH-a) therapy: role of mast cells and a possible mechanism of GnRH-a resistance in leiomyomasMasato Nakayama
Department of Obstetrics and Gynecology, Saitama Medical University, Saitama, Japan
Pathol Int 58:268-74. 2008..Thus, the present study may provide an explanation of the possible mechanism of GnRH-a resistance in UL... - Giant invasive pituitary adenoma extending into the sphenoid sinus and nasopharynx: report of a case with intraoperative cytologic diagnosisHatsumi Inagawa
Department of Pathology, Saitama Medical School Morohongo, Moroyama, Irumagun, Saitama, Japan
Acta Cytol 49:452-6. 2005..As compared to frozen sections, cytologic preparations are more effective for the intraoperative diagnosis of pituitary adenomas. Such neoplasms should always be included in the differential diagnosis of tumors involving the skull base... - Clinicopathologic features of epidermal cysts of the sole: comparison with traditional epidermal cysts and trichilemmal cystsYoshihiko Shimizu
Departments of Pathology and Dermatology, Saitama Medical School, Saitama, Japan
J Cutan Pathol 32:280-5. 2005..In this study, we compared the clinicopathologic findings of epidermal cysts of the sole with those of traditional epidermal cysts and trichilemmal cysts... - Interobserver variability in histologic recognition, interpretation of KIT immunostaining, and determining MIB-1 labeling indices in gastrointestinal stromal tumors and other spindle cell tumors of the gastrointestinal tractUmio Yamaguchi
Divisions of Orthopedic Oncology and Pathology, National Cancer Center Hospital and Research Institute, Tokyo, Japan
