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.

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.

Combined spinal epidural block with use of the needle-through-needle technique has become increasingly more popular during recent years because it provides rapidity and density of spinal block, combined with the ability to extend the block and provide postoperative analgesia by use of the extradural catheter. However, the combined spinal epidural block has some disadvantages. Since the spinal needle makes a hole in the dura, the accidental migration of an extradural catheter into the dural opening made previously by the spinal needle is thought to be theoretical risk. We report a case during combined spinal epidural anesthesia for a total hip replacement in which the clear fluid in the epidural catheter was found and tested to confirm the nature of fluid and migration of catheter by the dextrostix test and the immunoelectrophoresis test(prealbumin test).

Five cases of intracranial lipoma diagnosed by MR are presented. MR imaging was performed on a 0.2T permanent unit using T1 weighted, proton density-weighted, and T2 weighted spin echo sequences. In two patients, gadolinium-enhanced T1 weighted image was also obtained. The lipomas were located dorsolaterally to the splenium of the corpus callosum (n=1), inferior to the splenium (n=2), in quadrigeminal plate(n=1) and in the presumed corpus callosum area in the case of agenesis of corpus call?um (n=1). The size and shape of the lipomas were variable. No contrast enhancement was seen in post contrast study. Sagittal T1 weighted image appeared to be the most useful imaging plane for the demonstration of the relationship between the lipoma ad the adjacent normal structures. The Homogenous signal intensity paralleling the fat signal and the characteristic location of the lesion are considered to be helpful in the differential diagnosis from dermoid cyst or teratoma.
