Tailgut cyst is a rare congenital anomaly arising in the retrorectal space. Malignancy arising from the tailgut cyst is very rare. We experienced a case of adenocarcinoma arising from the tailgut cyst. The findings of this rare tumor are bony destruction of the sacrum on plain radiograph, a cystic mass on ultrasound, a low attenuation mass with calcification and enhancement on CT, and a multiseptated cystic mass containing solid component on MRI.

Avariety of symptoms can occur following traumatic brain injury(TBI) or other types of acquired brain injury. These symptoms can include problems with short-term memory, attention, planning, problem solving, impulsivity, disinhibition, poor motivation, and other behavioral and cognitive deficit. These symptoms may respond to certain drugs, such as dopaminergic agents. Amantadine may protect patients from secondary neuronal damage after brain injury as a effects of NMDA receptor antagonists and may improve functioning of brain-injured patients as a dopaminergic agonist. Clinically, based on current evidence, amantadine may provide a potentially effective, safe, and inexpensive option for treating the cognitive, mood and behavioral disorders of individuals with brain injury. The rationales for using amantadine are discussed, and pertinent literatures are reviewed.

Clear cell sarcoma of tendons and aponeuroses is the term coined by Enzinger in 1965 to describe a rare but unique type of soft tisse neoplasm whose cells characteristically have the capacity to produce melanin. The authors experienced a case of 64-year old female who presented with a 6x5x4 cm sized mass deeply seated in the left popliteal fossa. The mass was firm and multinodular, and on cut section revealed patches of brown black pigmentation. Histologically the tumor was composed of round to fusiform cells with clear or pale eosinophilic cytoplasm that contained small amounts of glycogen, separated into compact nests or short fascicles by delicate septa of fibrous tissue. The brown black pigment seen in tumor cells and stroma was proven to be melanin by special stain, and ultrastructural examination showed melanosomes in varying stages of development dispersed freely in the cytoplasm or in the lysosomes. These findings strongly support the view that clear cell sarcoma is a tumor of neural crest origin rather than of tenosynovial mesenchyme origin, and is a soft tissue variant of malignant melanoma.

We reported two cases of amantadine treatment in traumatic brain injury patients and reviewed the literature of amantadine treatment of those patients. Problems with short-term memory, attention, planning, problem solving, impulsivity, disinhibition, poor motivation, and other behavioral and cognitive dificit could occur following traumatic brain injury or other types of acquired brain injury. this report described results of amantadine using in two patients with this type of symptom profile. Patients received neuropsychiatric examination as well as BPRS and Barthel index. These patients were improved, respectively from 57 point to 82 point(case 1), from 85 to 94(case 2) in Barthel index, and from 66 point to 35 point(case 1), from 55 to 32 point(case 2) in BPRS. These two patients did not reveal any other adverse effect. The rationale for using amantadine were discussed.

Granulomatous(lobular) mastitis is a distinct disease entity of unknown etiology which is characterized by noncaseating granulomatous lobulocentric inflammation. We describe a rare case of granulomatous(lobular) mastitis of a 36 year-old pregnant woman a review of the literature. The mass which was discovered in the third month of her pregnancy, began as a localized, nontender mass on the left breast and persisted during her entire pregnancy. It decreased slightly in size when she began taking post-partum bromocriptine. Clinically and mammographically, the mass was highly suspected as a carcinoma with axillary lymph node metastasis. Fine needle aspiration smears revealed numerous aggregates of granulomas composed of epithelioid histiocytes admixed with multinucleated giant cells of Langhans' and foreign body type, and collections of polymorphonuclear leukocytes. Ziehl-Neelsen, silver methenamine and PAS stain were negative for acid-fast bacilli, fungus, and bacilli on the smear respectively. Histologically, granulomatous inflammation was centered on the breast lobules. Caseation necrosis was absent, instead, numerous microabscesses were formed in the center of the granulomas. Cultures of the fresh tissue for the AFB, aerobic and anaerobic bacteria, and fungus were all negative. Excision of the mass was performed without further treatment and there was no recurrence of the mass 6 months postoperatively. An autoimmune mechanism, infection, and some association with oral contraceptives have been suggested as etiologic factors in the literature.

The immunocompetence is important not only to kill the neoplastic cells but also to keep the neoplastic cells from growing further. T lymphocyte is plays the most important role in maintaining the tumor immunity efficiently. T lymphocyte has its specific functions depending in the subset of T lymphocytes. The author analyzed the T lymphocyte subsets in 31 brain tumor patients using anti-CD3, anti-CD4, anti-CD8 monoclonal antibodies and flow cytometry to determine the immunological status of brain tumor patients. All CD3, CD4 and CD8 subsets were reduced in both benign and malignant brain tumor patients but more signigicantly reduced in malignant tumor group. But in benign tumor group, the subtypes of T lymphocytes were not so different from those of normal healthy controls except the pituitary tumor patients, who showed the significant decrease in all the subtypes. In malignant tumor group, each subtype was signigicantly reduced and CD8 subtypes was markedly reduced in metastatic tumor patients, These analyses were considered to have the possibility to be contributable to planning the further immunotherapy and also the possibility to moniter the brain tumor patients clinically.
