Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

PURPOSE: This study focused on in vitro cell differentiation and surface characteristics in a magnesium coated titanium surface implanted on using a plasma ion source. MATERIALS AND METHODS: 40 commercially made pure titanium discs were prepared to produce Ti oxide machined surface (M) and Mg-incorporated Ti oxide machined surface (MM). Surface properties were analyzed using a scanning electron microscopy (SEM). On each surface, alkaline phosphatase (ALP) activity, alizarin red S staining for mineralization of MC3T3-E1 cells, and quantitative analysis of osteoblastic gene expression, were evaluated. Actin ring formation assay and gene expression analysis of TRAP and GAPDH performing RT-PCR were performed to characterize osteoclast differentiation on mouse bone marrow-derived macrophages (BMMs). RESULTS: MM showed similar surface morphology and surface roughness with M, but was slightly smoother after ion implantation at the micron scale. M was more hydrophobic than MM. No significant difference between surfaces on ALP activity at 7 and 14 days were observed. Real-time PCR analyses showed similar levels of mRNA expression of the osteoblast phenotype genes; osteopontin (OPN), osteocalcin (OCN), bone sialoprotein (BSP), and collagen 1 (Col 1) in cell grown on MM at 7, 14 and 21 days. Alizarin red S staining at 21 days showed no significant difference. BMMs differentiation increased in M and MM. Actin ring formation assay and gene expression analysis of TRAP showed osteoclast differentiation to be more active on MM. CONCLUSION: Both M and MM have a good effect on osteoblastic cell differentiation, but MM may speed the bone remodeling process by activating on osteoclast differentiation.

BACKGROUND: Laser resurfacing has beneficial effects for the treatment of several skin conditions. Recently, the pulsed erbium:YAG laser has been shown to be a highly effective treatment for several kinds of pitted facial scars. OBJECTIVE: The purpose of this study was to assess the efficacy and safety of pulsed erbium:YAG laser skin resurfacing at the setting of low or high energy for pitted acne scars. METHODS: 65 patients with pitted acne scars were included in this study. All patients had skin types III or IV. All patients were instructed to use tretinoin cream 0.05% nightly for 2-4 weeks prior to the laser treatment. The pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 mJ/pulse, 3.5-5 W in 45 patients and 1,000 mJ/pulse, 7-10 W in 20 patients was used. Two weeks after laser treatment, topical application of hydroquinone 4%, tretinoin 0.05%, and hydrocortisone 1% cream was recommended for 2-4 weeks. Facial photographs were obtained at baseline and 2 week intervals postoperatively. The results of treatment were evaluated for the changes of skin texture and color at 1 month, 3 months, and 6 months. RESULTS: In 45 cases treated with 500 mJ/pulse energy, pitted acne scars were improved about 46.7 % on average and no erythema and postinflammatory hyperpigmentation was observed after 6 months. In 20 cases treated with 1,000 mJ/pulse energy, pitted acne scars were improved about 64% on average and erythema in two patients and postinflammatory hyperpigmentation in one patient were observed after 6 months. CONCLUSION: The results of laser treatment for pitted facial acne scars at the setting of high energy are better than those of laser treatment at the setting of low energy.

Systemic lupus erythematosus is a systemic disorder which has frequent involvement of gastrointestinal tract. Non specific symptoms such as anorexia, nausea, diarrhea and abdominal pain are well known symptoms when the gastrointestinal tract is involved. The most feared gastrointestinal complication of systemic lupus erythematosus is lupus enteritis. The pathological change in lupus enteritis is usually a result of mesenteric vasculitis. Major complications such as intestinal bleeding and perforation may occur and sometimes result in sugery. Because of high mortality rate in case of major complications, early diagnosis and appropriate treatment is very important. We experienced three patients with lupus enteritis who presented with severe abdominal pain and dirrhea. They were diagnosed by characteristic radiographical findings of small bowel series and barium study. All radiographical findings has been resolved completely with the steroid therapy. Conclusively we can induce complete remission by steroid therapy alone, if we diagnose lupus enteritis in the early period of disease course.

Spontaneous renal rupture is relatively uncommon entity. In Korean literature, 8 cases have been reported. We experienced 1 case of spontaneous renal rupture secondary to hydronephrosis caused by metastatic adenocarcinoma of undetermined origin invading upper ureter and presented it with a brief review of literature.

Scrotal leiomyosarcoma arising from dartos layer not involving the testis, epididymis or spermatic cord is very rare tumor. We report a case of scrotal leiomyosarcoma in 29 year old man who present with right scrotal painless growing mass. The lesion had been for 3 months but there was no related symptom such as pain or tenderness. The excised lesion was 3 x 3cm sized ovoid mass with smooth surface and it had no relationship with the testis, epididymis and spermatic cord. Its pathologic finding was compatible with leiomyosarcoma. So additional radical orchiectomy was done.
