Sertoli-Leydig cell tumors of the ovary are rare, accounting for no more than 0.5% of all ovarian neoplasms. These tumors occur predominantly in women 10 to 30 years of age. Heterologous elements are found in over 20% of the moderately and poorly differentiated Sertoli- Leydig cell tumors. The most common element is gastrointestinal mucin-secreting epithelium, found in approximately 20% of all cases. Approximately 4% of Sertoli-Leydig cell tumors contain immature skeletal muscle and/or cartilaginous elements. The origin of these neoplasms is regarded as neometaplasia of the mesodermal neoplastic element. While the degree of differentiation of Sertoli-Leydig cell tumors is probably of greater importance in determining prognosis than the presence of heterologous components, recent evidence does point to an unfavorable effect on clinical outcome when heterologous mesenchymal components such as cartilage and striated muscle are present. We experienced two cases of ovarian heterologous Sertoli-Leydig cell tumors with gastrointestinal type epithelium and striated skeletal muscle in 20 and 21 year-old females, respectively. One case involved a patient who had complained of amenorrhea for 3 years while the other case involved a patient who had complained of left lower abdominal tenderness and amenorrhea for one and one half years. It was determined by ultrasonography of the pelvis that the two patients suffered from right and left ovarian masses. Both patients underwent adnexectomy. These tumors were large with partly solid and partly cystic areas. Based on light microscopic examination one case was classified as an intermediate Sertoli-Leydig cell tumor with heterologous gastrointestinal type epithelium, while the other case was classified as a poorly differentiated Sertoli-Leydig cell tumor with heterologous striated skeletal muscle.

The papillary eccrine adenoma is a rare benign sweat gland neoplasm charscterized by potentislly locally aggressive clinical course. We report herein a case of papillsry eccrine adenoma in a 28-year-old female who presented single intradermal tumor on the right postauricular ares. Histopathological findings showed dilated ducts containing eosinophilic or keratinous materials and intraluminal papillary rowths.

Three rare tumors of the oral cavity are presented. Lingual chondromas, approximately twenty to thirty cases appear to have been reported since the lesion was first described by Berry in 1892, which are usually seen on the lateral borders in the anterior two thirds of the tongue, while the ventral surface and the posterior third are rarely involved. Chondromas of the tonsil are of very rare occurrence, which are thought to arise as a result of metaplasia, rather than from embryonic rests, with chronic fibrosing inflammation being the inciting factor. Because of its rarity, the following cases of chondroma of the tongue and tonsil are being added to small list of such case reported in the literature.

The nevus of Ota is a benign dermal melanocytic lesion that most commonly occurs unilaterally in areas innervated by the first and second division of the trigeminal nerve. Acquired bilateral nevus of Ota-like macules(ABNOM) are located bilaterally on the forehead, temples, eyelids, cheeks, and/or nose. They usually occur in the fourth or fifth decade of life in women(rarely in men). In contrast to the nevus of Ota, ABNOM have not been observed in the mucous membranes of the oral cavity, nose, or eyes. Traditional treatments were palliative, risky electrocautery, or cryotherapy. These methods resulted in permanent pigmentary changes and/or scarring. Recently utilizing the principle of selective photothermolysis, the Q-switched Alexandrite laser has been reported to be successful in treating benign pigmentary lesions and tattoos. Our study evaluated the treatment of 127 patients with nevus of Ota and ABNOM with the Q-switched Alexandrite laser(755 nm, 100 nsec). Nevi were treated up to 7 times with 7-8 J/cm2 at a minimum of 6 weeks interval. Good therapeutic effects were gained (up to 50% improvement was seen in 89% of patients.) and our patients were very satisfied. No patients had permanent textural change or scarring. Treatment with on Alexandrite laser for nevus of Ota & ABNOM is considered to be a safe and effective method.

Excess hair growth in unwanted areas may result from heredity, endocrine disease, or drug therapy. Conventional methods of hair removal include shaving, wax epilation and chemical depilatories that frequently cause side effects such as contact dermatitis and that also have temporary effects. Electrolysis is a well-established medical method for permanent destruction of terminal hair follicles. However, this method is tedious and efficacy has been reported to range from 15-to-50% permanent hair loss. The evolution of the laser use for hair removal continues a year after Food and Drug Administration (FDA) approval of the first laser for these applications. The authors have experienced hair removal utilizing a long-pulsed alexandrite laser. This laser system employs the principle of thermokinetic selectivity, a revolutionary concept. The principle of thermokinetic selectivity involves the use of lasers with pulse durations below the thermal relaxation on a the large target such as the hair folllicle (40-100 msec), and significantly longer than the thermal relaxation time of smaller structures of the same chromophore (melanin) in epidermis (3-10 msec). The study was based on 76 patients treated with 20 msec pulse duration laser set to energy densities of 17-21 J/cm2. Treated areas included arms, legs, beard-chin, upper lips and bikini lines. Gross observation showed leaching of hair color, decresed size of the skin pores, easily broken hair shafts, and elimination of hair. Therefore, it can be assumed that the majority of hair follicles were destroyed by this procedure, Side effects included intermediary risk of hyperpigmentation and blister. Over 80% of treated patients were satisfied with the results. As the process of research and clinical application continues, we need the long-term results of this laser system to ensure its efficacy.

PURPOSE: The accuracy of CT in the detection of injuries of the solid visceral organ is well established, but the value of CT in diagnosing small bowel rupture after abdominal trauma is controversal. This study was conducted to ascertain CT finding of small bowel rupture result from abdominal trauma. MATERIALS AND METHODS: A retrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel rupture was confirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. RESULTS: Diagnostic findings of small bowel rupture including pneumoperitoneum or retroperitoneal air, discontinuity of the bowel wall and extravasation of oral contrast materials were observed in 33 cases(83%). Intraperitoneal or retroperitoneal free air was seen in 31 cases(78%) and intraperitoneal or retroperitoneal free fluid collection was seen in 38 patients(95%). Small bowel wall was thickened in 31 cases(78%), bowel wall was enhanced in 12 cases(30%) and bowel wall discontinuity and extravasation of oral contrast material was seen in 5 cases, respectively. CONCLUSION: The CT scan is sensitive and effective modality for evaluation of small bowel rupture after abdominal trauma, because of high detectability of diagnostic and suggestive CT findings.
