Infantile myofibromatosis with systemic involvement is a very rare disease and is characterized by numerous nodules composed of spindle cells of a myofibroblastic nature. There are often disseminated throughout the subcutis, muscle, skeleton and viscera. We report an autopsy case of infantile myofibromatosis in a stillborn female fetus of 32 weeks of gestation. The nodules, Imm to 2 cm, were found over the whole body and viscera. The involved viscera were the heart, tongue, esophagus, gastrointestinal tract, portal areas of the liver, spleen anc pancreas. There were also associated malformations, viz., frontal meningoencephalocele, flexion defer-mities, syndactyly, cleft palate, agenesis of corpus callosum, pachygyria, diaphragmatic hemia, renal hypoplasia, etc. Multiple basaloid follicular hamartomas of the skin were noted on the face and extremeties. There are no previous reports in the literature of infantile myofibromatosis in conjunction with the above skin lesion and congenital malformations.

2.A Clinical Study of Sellar and Parasellar Lesions.
Journal of Korean Neurosurgical Society 1973;2(2):37-50
A series of 58 verified various sellar and parasellar lesions exclusive of aneurysms and inflammatory lesions was reviewed as to history, development and progression of the neurological features, spontaneous and steroid induced remission, endocrine disturbances, other laboratory findings, reontgenograms, differential diagnosis, operative methods and findings, and pathologic findings of the lesion. The author has only emphasized some interesting points illustrated in our cases because other results do not differ greatly from previous authors' reports. 1. No direct correlation was found to exist between the amount of the sellar destruction and the occurrence of endocrine disturbances. However, it was likely that marked endocrine changes were due to cystic formation in pituitary adenomas. 2. On angiograms of sellar and parasellar lesions, opening of the siphon and lateral displacement of the supraclinoid portion of the internal carotid artery were important in the diagnosis, and the event of nonvisualization of the posterior communicating and posterior cerebral arteries was observed in the majority of pituitary tumors. 3. In pituitary cystic adenomas, intracapsular bleeding was very hard to control on occasions because of rupturing vascular network or trabeculae in the cyst. 4. Definition of the empty sella was always obscure in intracranial exploration under the diagnosis of pituitary tumor when no definite lesion was found. 5. In a hydrocephalic patient with raised intracranial pressure and a markedly enlarged third ventricle extending into the sella turcica, third ventriculostomy still seems to be the choice of treatment.

BACKGROUND: We described a surgical method for osteosynthesis and reported the resultant strength after application of a PHILOS plate through the anterolateral approach for the treatment of fractures of the distal humerus. METHODS: Between February 2010 and March 2012, open reduction and internal fixation operations with the PHILOS plate for treatment of fracture of the distal humerus were performed on a total of nine patients (five men, four women). The mean age was 40.8 years (range, 24-50 years), and the average follow-up period was 9.1 months (range, 6-15 months). Clinical evaluations were performed 6 months after the operation. Clinical assessment included determination of the range of motion of the elbow, the Mayo and Oxford elbow scores, and any postoperative complications. RESULTS: Fracture union was noted in all patients, with an average period of 12.4 weeks. The average Mayo elbow and Oxford elbow scores were 87.2 (of a total of 100) and 43.3 (of a total of 48), respectively. For the postoperative range of motion of the elbow, all patients showed complete recovery to the preoperative range of motion. No other conditions, such as neurolepsis, plate breakage, or rotational deformity, were observed. CONCLUSIONS: Open reduction and internal fixation of distal humerus fractures with a PHILOS plating system via anterolateral approach can be effective. A high rate of union with good outcomes can be assumed.

Erlotinib (Tarceva(R)) is a new anti-cancer agent that acts by inhibiting epidermal growth factor receptor (EGFR) signal transduction. It is currently used in the treatment of advanced stage non-small cell lung cancer and pancreatic cancer. A patient consulted our clinic and she had erythematous patches and vesicles on the submandibular area. She had taken erlotinib for the treatment of recurred lung cancer for 2 weeks. We report here on a case of radiation recall dermatitis that was induced by erlotinib in a 69-year-old woman who was previously irradiated on her submandibular area.

Intra-epidermal epithelioma is a rare cutaneous neoplasm and generally used as a histologic description for superficial tumors in which nests are found in well-defined islands within the epidermis. The intra-epidermal nests are composed of keratinocytes, and basaloid or squamoid or pleomorphic cells. Some authors reported that this tumor may be considered an invasion of the epidermis from a malignant tumor and it has the potential of carcinomatous invasion. Herein, we report a case of intra-epidermal epithelioma that showed clonal seborrheic keratosis and intra-epidermal eccrine poroma differentiation on the right thigh areaof a 77-year-old female. Although intra-epidermal epithelioma shows benign features, it may be predisposed to other tumoral changes, such as eccrine poroma, eccrine porocarcinoma, and Bowen's disease. We suggest that individuals with intra-epidermal epithelioma require continuous monitoring of skin changes, including enlargement of size, inflammation, ulceration, and hemorrhages.

Neurilemmoma is the most frequent solitary tumor of the peripheral nerves. It is a tumor from Schwann cells, and it is usually solitary and benign. Treatment of this benign lesion is usually by excisional biopsy. This report concerns a rare case of neurilemmoma developed in the penis in a 51 years old male and the relevant literature has been reviewed.

In this prospective study, 208 cases of ptosis were repaired using dried preserved fascia lata as suspension material for frontalis sling procedure during 1990 to 1996. The average age at operation was 9.2 years with the range of 2 months to 56 years. One hundred forty one patients (91.0%) of the 155 patients with follow-up of more than 3 months and 99 (90.8%) of the 109 patients with follow-up of more than 6 months showed satisfactory results respectively. Among 12 unsatisfactory cases six patients underwent reoperation and achieved satisfactory results. Exposure keratitis was the most common complication (39.4%)but most of them were transient. The authors report frontalis sling operation using preserved fascia lata with 96.3% of success rate with few complications.

Tuberculosis can involve any part of the body and there are case reports of tuberculosis coexisting with malignancy in most body organs. However, cases of intestinal tuberculosis associated with colon cancer have rarely reported. Inflammatory bowel diseases can progress to malignant diseases due to mucosal dysplastic change. Similarly, intestinal tuberculosis can cause chronic inflammation, but the exact relationship between intestinal tuberculosis and colon cancer is currently obscure. A 71-year-old woman visited our hospital because of abrupt right lower abdominal pain that progressed to rebound tenderness and abdominal rigidity. Abdominal computed tomography showed a polypoid mass in the cecum and a distended terminal ileum. Right hemicolectomy was performed and the surgical specimen revealed extremely well differentiated adenocarcinoma combined with intestinal tuberculosis and bowel perforation in the cecum. We report here on a rare case of colon cancer coexisting with colonic tuberculosis and this presented as bowel perforation. We also include a review of the relevant literature.

OBJECTIVE: Functional magnetic resonance imaging (fMRI) is frequently used to localize language areas in a non-invasive manner. Various paradigms for presurgical localization of language areas have been developed, but a systematic quantitative evaluation of the efficiency of those paradigms has not been performed. In the present study, the authors analyzed different language paradigms to see which paradigm is most efficient in localizing frontal language areas. METHODS: Five men and five women with no neurological deficits participated (mean age, 24 years) in this study. All volunteers were right-handed. Each subject performed 4 tasks, including fixation (Fix), sentence reading (SR), pseudoword reading (PR), and word generation (WG). Fixation and pseudoword reading were used as contrasts. The functional area was defined as the area(s) with a t-value of more than 3.92 in fMRI with different tasks. To apply an anatomical constraint, we used a brain atlas mapping system, which is available in AFNI, to define the anatomical frontal language area. The numbers of voxels in overlapped area between anatomical and functional area were individually counted in the frontal expressive language area. RESULTS: Of the various combinations, the word generation task was most effective in delineating the frontal expressive language area when fixation was used as a contrast (p<0.05). The sensitivity of this test for localizing Broca's area was 81% and specificity was 70%. CONCLUSION: Word generation versus fixation could effectively and reliably delineate the frontal language area. A customized effective paradigm should be analyzed in order to evaluate various language functions.
