Lupus pernio is the most characteristic cutaneous lesion of sarciodosis and this presents as an indurated red to blue-purple, swollen, shiny lesion that is often localized on the nose, cheeks, lips or ears of middle-aged female adults. It is a chronic malady that rarely shows spontaneous remission, and it sometimes causes deformity. It generally occurs as cutaneous lesions of sarcoidosis patients with a long duration of disease, and not as early cutaneous lesions of sarcoidosis. This case concerns a 43-year-old woman who presented with a 1 year history of firm erythematous and violaceous plaque with multiple erythematous and violaceous papules on the collumella and right nasal cavity. Skin biopsy showed noncaseasting granuloma. Herein, we report on a typical case of lupus pernio as the early cutaneous presentation of sarcoidosis, which has rarely been reported in the Korean literature. We suggest that early diagnosis and treatment is necessary to prevent deformity.

Parry Romberg Syndrome (PRS), also known as idiopathic progressive hemifacial atrophy, is a rare neurocutaneous disorder characterized by loss of skin and subcutaneous fat of face, muscles, and bones causing unilateral atrophy. Most patients require only soft tissue augmentation although syndrome has varying grades of severity. In the majority of reported cases, it has been treated with surgical flap or autologous fat transplantation. However, these treatments need complicated surgical skills which take a lot of time and cost. Herein we report the first case of PRS augmented by hyaluronic acid (HA) filler in a 42-year-old female patient to suggest that HA filler could be a safe, simple, and even rational economic alternative to surgical treatment.

Purpose:
To evaluate the effect of intraoperative mitomycin C (MMC) on the surgical outcomes of ciliary sulcus (CS) Ahmed glaucoma valve (AGV) tube placement.
Methods:
A retrospective review of medical records of 54 consecutive patients who underwent AGV implantation with tube placed in CS was performed. Consecutive cases operated without the use of intraoperative MMC from 2017 to 2019 were compared with consecutive cases operated with MMC from 2019 to 2021. Surgical failure was defined as intraocular pressure (IOP) exceeding 21 mmHg in two consecutive visits after postoperative 3 months or ≤30% IOP reduction, IOP ≤5 mmHg in two consecutive visits, or loss of light perception. Kaplan-Meier survival analysis and log-rank test were performed to compare the surgical failure rates.
Results:
A total of 54 eyes of 54 patients were investigated. Mean follow-up period after AGV implantation was 1.4 ± 0.8 years. The MMC group showed significantly lower IOP during the 1st postoperative month (20.5 ± 8.6 mmHg vs. 15.8 ± 6.4 mmHg, p = 0.027), but the difference did not persist 6 months after the surgery (p = 0.805). The mean number of postoperative antiglaucoma medications was significantly lower in the MMC group in the 1st postoperative month (p = 0.047) but no difference was found at 6 months. No statistical difference was noted in the rates of postoperative complications. Kaplan-Meier survival analysis showed comparable survival rates between MMC group and no MMC group (p = 0.356).
Conclusions
The intraoperative use of MMC significantly lowered IOP in the 1st postoperative month but did not increase 6 months success rates in patients receiving AGV tube placement in CS.

PURPOSE: The purpose of this report is to describe the proton therapy system at Samsung Medical Center (SMC-PTS) including the proton beam generator, irradiation system, patient positioning system, patient position verification system, respiratory gating system, and operating and safety control system, and review the current status of the SMC-PTS. MATERIALS AND METHODS: The SMC-PTS has a cyclotron (230 MeV) and two treatment rooms: one treatment room is equipped with a multi-purpose nozzle and the other treatment room is equipped with a dedicated pencil beam scanning nozzle. The proton beam generator including the cyclotron and the energy selection system can lower the energy of protons down to 70 MeV from the maximum 230 MeV. RESULTS: The multi-purpose nozzle can deliver both wobbling proton beam and active scanning proton beam, and a multi-leaf collimator has been installed in the downstream of the nozzle. The dedicated scanning nozzle can deliver active scanning proton beam with a helium gas filled pipe minimizing unnecessary interactions with the air in the beam path. The equipment was provided by Sumitomo Heavy Industries Ltd., RayStation from RaySearch Laboratories AB is the selected treatment planning system, and data management will be handled by the MOSAIQ system from Elekta AB. CONCLUSION: The SMC-PTS located in Seoul, Korea, is scheduled to begin treating cancer patients in 2015.
