Partial trisomy 10q syndrome is a rare chromosome anomaly characterized by severe mental and growth retardation, craniofacial dysmorphia with prominent forehead, fine arched eyebrows, deep set small eyes and micrognathia, In addition, other physical manifestations have been reported as skeletal anomaly, congenital heart disease, inguinal hernia, and so on. We report a case of partial trisomy 10q syndrorne with certain stigmata which confirmed by chromosome analysis.

We report a medullary carcinoma of the thyroid gland with a coexisting occult sclerosing papillary carcinoma. This rare case, in that the two types of carcinoma are completely separated and not intermixed together, is different from the previously reported mixed follicular and parafollicular cell carcinomas of the thyroid gland, so-called "differentiated thyroid carcinoma, intermediate type". The two separate tumors of the present case are undoubtedly of coincidental double primaries, and it can be a assumed that at least some of the mixed follicular and parafollicular cell carcinomas are results of collision of carcinomas derived from two embryogenetically different cell types.

Gottron's acrogeria syndrome is a rare genetic disease of unknown etiology with some features suggestive of accelerated aging. The typical clinical presentation consists of premature aging of the skin with atrophy of the cutis and the subcutis. After a brief review of the literature available on this syndrome, we report a case of Gottron s acrogeria syndrome in a 19 year-old man whose right rectus femoris muscle had a fibrotic contracture.

9.Role of Radiation Therapy for Non-small Cell Lung Cancer: Focused on Stereotactic Ablative Radiation Therapy in Stage I.
Hanyang Medical Reviews 2014;34(1):45-50
Radiation therapy has played a key role, together with surgery and systemic chemotherapy, in treating in all stages of non-small cell lung cancer. We have witnessed remarkable improvements in radiation therapy techniques, with the innovations in hardware and software. Stereotactic ablative radiation therapy, which can deliver high radiation dose focused to small target volume, represents one of the state-of-the-art radiation therapy techniques. The technical development of radiation therapy and the role of stereotactic ablative radiation therapy in treating inoperable stage I non-small cell lung cancer are briefly reviewed.

PURPOSE: To develop the dose volume histogram (DVH) management software which guides the evaluation of radiotherapy (RT) plan of a new case according to the biological consequences of the DVHs from the previously treated patients. MATERIALS AND METHODS: We determined the radiation pneumonitis (RP) as an biological response parameter in order to develop DVH management software. We retrospectively reviewed the medical records of lung cancer patients treated with curative 3-dimensional conformal radiation therapy (3D-CRT). The biological event was defined as RP of the Radiation Therapy Oncology Group (RTOG) grade III or more. RESULTS: The DVH management software consisted of three parts (pre-existing DVH database, graphical tool, and Pinnacle3 script). The pre-existing DVH data were retrieved from 128 patients. RP events were tagged to the specific DVH data through retrospective review of patients' medical records. The graphical tool was developed to present the complication histogram derived from the pre-existing database (DVH and RP) and was implemented into the radiation treatment planning (RTP) system, Pinnacle3 v8.0 (Phillips Healthcare). The software was designed for the pre-existing database to be updated easily by tagging the specific DVH data with the new incidence of RP events at the time of patients' follow-up. CONCLUSION: We developed the DVH management software as an effective tool to incorporate the phenomenological consequences derived from the pre-existing database in the evaluation of a new RT plan. It can be used not only for lung cancer patients but also for the other disease site with different toxicity parameters.
