Solitary circumscribed neuroma is a benign nerve sheath tumor of unknown etiology. Clinically, it appears as a long-standing, solitary, asymptomatic, skin-colored papule or papulonodule. It has been found predominantly on the face in both sexes, mostly in middle age. A 53-year-old female patient visited our department because of a nodule on the side of the distal interphalangeal joint of the left second finger. A biopsy specimen showed a well-circumscribed, partially encapsulated tumor composed of interlacing fascicles of spindle cells. Neither pleomorphism nor mitosis was found. Immunohistochemical stainings for vimentin, neuron specific enolase (NSE) and epithelial membrane antigen (EMA) were positive, but negative for S-100 protein and smooth muscle actin (SMA). We herein report an uncommon case of solitary circumscribed neuroma.

We studied skin thickness of the twelve body sites in 25 post-mortem subjects. The most thinnest and thickest sites of the skin layers are as follows(unit: um) l. In the horny layer, eyelid(13.16+/-5.44) and sole(420.83+182. 25), respectively 2. In the granular, eyelid, posterior ear, abdomen, back, thigh, forearrn(1 layer)and sole(3.4+/-0.59 layers), respectively 3. In the prickle cell layer(to rete ridge), forearm(50. 21+/-15. 36) and sole (174.72+/-84.41), respectively 4. In the prickle cell layer(to papillary dermis), abdomen (33. 05+/-10. 28) and sole (106.13+/-73.62), respectively 5. In the epidermis, eyelid (61.60+/-16.53) and sole (972.00+/-228. 16), rpspectively 6. In the dermis, eyelid(878.08+283. 56) and back(3596.05+/-1306.80), respectively.

This study was aimed to investigate the clinical manifestation of nail changes in psoriasis and was based on analysie of 205 p oriatics visited the department of dermatology, Seoul National University Hospital from November, 1984 to June, 1985. The results were summerized as follows: Nail changes were noted in 78(38. 0%) out of 205 patients in the finger nails. Toe nails were involved in 26(12 7%) cut of 205 patients. 2 Nail changes in male were noted in 49 (46, 7%) out of 105 patients and in female, 29(29%) out of 100 patients. 3. The peak incidence of nail changes according, to age group was over 40 years (45. 1%.) and the lowest incidence, under 9 years(26. 7%). 4, Pitting(57. 7%) was the commonest change ii the finger nails and subungal keratosis(50. 0%) and discoloration(46 2%) in the toe nails. 5 Incidence of nail changes according to psoriatic type was 23. 7% in guttate type, 42. 6% in nummular type, 53 3% in annular type. 6 The patients with the more severe degrees of psoriasis had a higher incidence of nail involvement. Mean duration of psoriatics with nail change and without nail change was 6. 3 years and 6. 5 years, respectively, 8 Among 65 patients with psoriatic nails, onychomycosis was noted in 9 patients(13.8%).

Neurilemmomatosis is a clinical entity consisting of multiple cutaneous neurilemmomas, central nervous system tumors, and neurologic disorders. Since Shishiba et al first described the disorder in 1984, several cases have been reported. We report a Korean case of neurilemmomatosis showing multiple neurilemmomas of the skin and spinal cord, with associated motor and sonsory nerve disturbance. Histologic, immunohistopathologic and electron microscopic studies confirmed the diagnosis.

The epithelioid angiosarcoma is recently described ns a variant of ang-osarcoma based on its pathological feature, which is characterized by the epithelioid or histiocytoid morphology af the malignant tumor cells. The existence of vascular endothelial tumor with an epithelioid feature has been accepted for many years, most notablyn the forms of epithelioid hemangioma and epithelioid hemangioendo thelioma. In recent years, cutaneous angiosarcoma with epitheloid morphology have been reported as a cutaneos epithelioid angiosarcoma in the literatures. A 60-year-old man presente with a mild tender erythematous 2 x 2 x 2.5cm sized soft fluctuating single nodule with dark hemorrhagic crust on the left forehead for 3 months. He had had an abrasion wound on the lesion site of the forehead by an accidental trauma 5 month before the lesion appeared. Histopathological findings revealed that the tumor mass was chiefly composed of solid sheets of poorly differentiated malignant cells with an epithelioid feature. The characteristics of classical angiosarcoma such as primitive vascular spaces and clefts with malignat cells, and proliferating vessels were also found in some areas. The immunohistochemical stain wi.h the factor VIII related antigen ivas focally reactive in the tumor cells. Unfortunately he refused further treatment and expired 7 months after discharge at home without knowing the direct cause of his health. We report herein an interesting and rare case of the cutaneous epitheioid angiosarcoma which had typical clinical and histopathological findings and suggested as a case with a very aggressive course.

Following the Korean War, the presence of foreign troops in Korea and lowered. sexual morality caused an increase in the rate of prostitution and related venereal diseases. Though the health authorities made efforts to handle these problems, they didnt obtain any noticeable results, because they neglected the scientific prevention and treatment based on expert knowledge, and the sociopsychological problem, which was the basic cause of the increment in the rate of prostitution. They only took administrative action against the prostitutes. Therefore, in July, 1976, we went to a town(named Silver Town) located on the outskirts of a U.S. Air Force base, and, examined and guestioned a number of prostitutes. Each of the 288 subjects residing in the town was given a questionaire that dealt with individual living attitudes, family and social background, and sociopsychological aspects of tbeir lifestyle. Questionaires were completed anonymously. Serological tests for syphilis, the UDRL and TPHA, were also administered. The results of our atudy are as follows. 1) Most of the prostitutes had grown up in large families, in which females were predominant. Because of economic difficulties they dropped out of school a.t an early age and became prostitutes. The average age of a prostitute at the time of her first sexual experience was 19. 9 years, the expriences usually taking place with her first boyfriend. Forty six psrcent of tbe subjects had intercourse for the first time between the ages of 15 and 19. Fortynine & two tenths percent of them because prostitutes within one year of their initial sexual act, and all of them at an average interval of 2.5 years following the first sexual experience, the average age being 22. 4 years. 2) The longer the women had worked as prostitutes, the more they felt dissatisfied with their work, and the more they desired to change to an occupation which was healthier and entailed more self-respect. 3) Out of 283 subjects, 39% had a history of venereal disease, predominantly of gonorrhea. Tbe results of the STS administered to all subjects were,; VDRL 7.7% positive and TPHA 6% positive. It was also concluded that the subjects had no educational or working knowledge of venereal diseases.
