This clinical and histopatholgical study was performed with 149 cases of acquired melanocyticnevi, which were obtained as surgical specimens from 1975 to 1985 at Depa.rtment of Clinical Pathology, Seoul Red Cross Hopital. The results were as follows: 1) Histologic subdivision of melanocytic nevus into junctional(,J), IJC, compound (C,"), ICI, and intradermal(I) is used. IJC is a lesion in an intermediate state between ,junctional and compound nevus, and ICI, between compound and intradermal nevus. 2) The age distribution of the excisional melanocytic nevus peaks during the third decade of life, with 47% of patients between 21 40 year old of age. 3) Of l49 specimens with excisional melanocytic nevus, the number of junctional, IJC, compound, ICI and intradermal nevus were 17, 4, 21, 32 and 75 in each group And so, it is likely that evolution of the melanocytic nevus have an increased opportunity for surgical excision. 4) Among the 17 cases of junctional nevus, one case is found in 5th and the other one in 7th decade. 5) In distvibution of melanocytic nevus, head including face is the most common site among the body area and then trunk, neck, lower and upper extremity in decreasing orders.

Eccrine angiomatous hamartoma or sudoriparous angioma is a hamartoma in which histologically, hyperplasia of eccrine sweat apparatus and vascular elements is present in the same lesion and clinically has tenderness and hyperhidrosis over the lesion. We present a case of eccrine angiomatous hamartoma developed on the medial side of the right knee in a 5-year-old female patient.

Isolated ACTH deficiency is a rare disorder, and usually characterized by its chronic course. The 59 year-old woman patient who had been healthy until 2 months ago, admitted because of abdomial pain, general weakness and loss of weight about 12kg for 2 months. She looked a little pallor but color of skin was not remarkable. Blood pressure, serum electrolyte, and glucose on admission were within normal range. Serum calcium was elevated with the value of 12.6mg/dL, which was normalized after hydration. Cortisol response to RI induced hypoglycemia did not show any response. Anterior pituitary hormone except ACTH showed normal response during combined pituitary hormone stimulation test. These clinical and laboratory finding reveals that isolated ACTH deficiency was developed in a short term period. There were no abnormalities in sellar MRI except pineal cyst. Her complaints were disappeared dramatically after hydroccetisone replacement at 4th. hospital day. Here we report a case of isolated ACTH deficiency, which was rapidly developed, with hypercalcemia, abdominal pain, and loss of weight about 12kg for 2 months.

OBJECTIVE: Although little is known about its origins, neck pain may be related to several associated anatomical pathologies. We aimed to characterize the incidence and features of chronic neck pain and analyze the relationship between neck pain severity and its affecting factors. METHODS: Between March 2012 and July 2013, we studied 216 patients with chronic neck pain. Initially, combined tramadol (37.5 mg) plus acetaminophen (325 mg) was administered orally twice daily (b.i.d.) to all patients over a 2-week period. After two weeks, patients were evaluated for neck pain during an outpatient clinic visit. If the numeric rating scale of the patient had not decreased to 5 or lower, a cervical medial branch block (MBB) was recommended after double-dosed previous medication trial. We classified all patients into two groups (mild vs. severe neck pain group), based on medication efficacy. Logistic regression tests were used to evaluate the factors associated with neck pain severity. RESULTS: A total of 198 patients were included in the analyses, due to follow-up loss in 18 patients. While medication was successful in reducing pain in 68.2% patients with chronic neck pain, the remaining patients required cervical MBB. Lateral cervical curvature, such as a straight or sigmoid type curve, was found to be significantly associated with the severity of neck pain. CONCLUSION: We managed chronic neck pain with a simple pharmacological management protocol followed by MBB. We should keep in mind that it may be difficult to manage the patient with straight or sigmoid lateral curvature only with oral medication.

We examined the hypothesis that mild hypothermia (rectal temperature 34 degrees C) results in the same survival time, whether induced spontaneously or intentionally, during untreated, lethal, uncontrolled hemorrhagic shock in rats. Sixty-four Sprague-Dawley male rats were randomly assigned to normothermia (Nth) (n=19), spontaneous mild hypothermia (Sp.Hth) (n=25) or controlled mild hypothermia (Con.Hth) (n=20) groups. After blood withdrawal of 3 mL/100 g over 15 minutes, followed by 75% tail amputation under spontaneous breathing and light anesthesia by i.p. injection of pentobarbital sodium, rats were observed without fluid resuscitation or hemostasis for 180 minutes or until death. The initial temperature of the Nth group was artificially maintained throughout the experiment. For the mild hypothermia groups, the Sp.Hth group was exposed to ambient temperature while the Con. Hth group was actively cooled to a target rectal temperature of 34 degrees C. In the Con.Hth group, all rats except one died before 180 minutes. All rats in the Nth group died within 38 minutes, and within 67 minutes in the Sp.Hth group. The average survival time was shortest in the Nth group at 20.3 +/- 5.3 minutes, followed by the Sp.Hth group at 30.1 +/- 13.5 minutes, and the Con.Hth group at 81.9 +/- 39.8 minutes (p 0.01). Tail bleed out volume was 0.51 +/- 0.19, 0.26 +/- 0.15 and 0.19 +/- 0.12 mL/100 g in the Nth, Sp.Hth and Con.Hth groups, respectively (p 0.05). In conclusion, spontaneous mild hypothermia did not prolong the survival time as much as controlled mild hypothermia in the rat model for untreated, lethal, uncontrolled hemorrhagic shock.

The authors have experienced a case of extrascleral extension of choroidal malignant melanoma. The patient has suffered from the ocular pain and proptosis of right eye. We performed Kronlein operation under the clinical impression of the retrobulbar mass and obtained the histopathological diagnosis of malignant melanoma. Fifteen days after the operation, we performed exenteration and the rotation flap of temporalis muscle was inserted into the right eye ball socket through the lateral wall of the orbit.

Aldosterone-producing adrenal adenoma can induce various clinical manifestations as a result of chronic exposure to aldosterone. We report a rare case of a 37-year-old man who complained of general weakness and polyuria. He was diagnosed with aldosterone-producing adrenal adenoma and nephrogenic diabetes insipidus. Aldosterone enhances the secretion of potassium in the collecting duct, which can lead to hypokalemia. By contrast, nephrogenic diabetes insipidus, which manifests as polyuria and polydipsia, can occur in several clinical conditions such as acquired tubular disease and those attributed to toxins and congenital causes. Among them, hypokalemia can also damage tubular structures in response to vasopressin. The patient's urine output was > 3 L/d and was diluted. Owing to the ineffectiveness of vasopressin, we eventually made a diagnosis of nephrogenic diabetes insipidus. Laparoscopic adrenalectomy and intraoperative kidney biopsy were subsequently performed. The pathologic finding of kidney biopsy revealed a decrease in aquaporin-2 on immunohistochemical stain.

Symptomatic neuroepithelial cysts of the lateral ventricles are rare. The CT and MRI findings of the intraventricular neuroepithelial cysts in the surgically proven three cases are reported. On CT, the cysts had density similar to CSF, and the cyst walls were generally not seen. The cyst contents were slightly higher signal than CSF signal in Tl-weighted and proton density MR images. The delicate cyst walls were easily seen in spin echo MR images. MRI was better than CT in the demonstration of the cyst wall and the evaluation of the cyst content in patients with neuroepithelial cysts in the lateral ventricles.
