Glomus tumor shows histologically characteristic three components of glomus cells, vascular structures, and spindle-shaped smooth muscle cells. It is classified into solid glomus tumor, glomangioma and glomangiomyoma according to relative proportions of components. Glomangiomyoma, the least frequent type of glomus tumor, has its overall histopathologic pattern identical to common solid glomus tumor or glomangioma. In contrast to the foregoing types, however, it has an important number of spindle-shaped smooth muscle cells, which blend with the glomus cells. A 49-year-old woman presented with 2-year history of painful bluish red nodule beneath nail plate of right 4th finger. We made a diagnosis of glomangiomyoma by virtue of routine histopathologic examinations and immunohistochemical stains such as vimentin, smooth muscle actin and desmin.

We report a detailed course of one case of Gianotti-Crosti syndreme in 9 year-old boy. Characteristically the case presented cutaneous eruptions as its first clinical symptom. The eruptions were seen for five weeks and abnormal liver function tests persisted at least more than four months. The case caused the authors to think that alertness to the syndrome in dermatological clinic is necessary, especially in the country where viral hepatitis is endemic.

Livedo reticularis is a mottled bluish discoloration of the skin which occurs in a netlike pattern and is not a diagnosis in itself, but is a nonspecific reaction pattern. It may be classified as idiopathic and secondary livedo reticularis. Decompression sickness can occur during decompression after diving into deep sea water or during a rapiid ascent from sea level, and is one of the many causes of the secondary livedo reticularis. We report a case of livedo reticulris which developed in a patient with decompression sickness. A biopsy from the purpuric patch revealed an unusual histopathologic finding that resembles those of bullae and sweat gland necrosis in drug induced coma.

Occasionally, erythema multiforme has been reported to occur in association with allergic contact dermatitis to various substances including paraquat(Gramoxone(R)). In these cases the erythema multiforme has ranged from mild localized exanthem to life-threatening toxic epidermal necrolysis. We report a case of toxic epidermal necrolysis developed from erythema multiform due to contact of paraquat.

Tumor suppressive effect of dehydroepiandrosterone (DHEA) on the experimentally induced hepatocellular carcinoma was investigated, especially focusing on glutatione transferase and transglutaminase with aptosis in the carcinogenesis. The chemical hepatocarcinogenic procedure of Solt-Farber method was used on Sprague-Dawley rats. Experimental groups were divided into AA group treated by the standard Solt-Farber regimen of diethylnitrosamine (DEN) and 2-acetamidofluorene (AAF) and AD group treated with DHEA simultaneously with AAF and the AAD group treated by DHEA after treatment with AAF. Each group was divided by time sequence further into four subgroups, GI (8wk), G2 (16wk), G3 (28wk), and G4 (36wk). For neoplastic lesion, the immuno histochemical study with anti GSTP antibody was carried out, while the activity and expression of TGase was compared at the same time. The results were summarized as follows; GST-P positive foci detected in AD groups were significantly more suppressed by DHEA treatment than AA groups (P<0.05). AD groups. AD group showed higher activities of TGase than AA groups (P<0.05), which was confirmed by Western and Northern blot analysis. But the number of apoptotic bodies was not correlated with activity and expression of TGase in the nodule. These results suggest that the suppressive effect of DHEA on the murine hepatocellular carcinogenesis might be operating on the promotion process of carcinogenesis rather than regression process of transformed hyperplastic nodules.

Esophageal granular cell tumor of is rare neoplesin, and 3 cases were reported in Korea so far. We report a case of esophageal granular cell tumor in a 28 year old man. The patient was a 28 year old man who visited this hospital because of upper abdominal pain, acid belching and weight loss. A small nodule, 5 mm in diameter, was found in mid esophagus on esophagoscopy. This nodule was proved to be a granular cell tumor.

BACKGROUND: Although rubella is a mild exanthematous viral infection and its incidence has been greatly decreased after effective vaccination, epidemics of rubella has been noted at 5- to 7-year intervals. But there has been few report about the clinical and histopathologic study of rubella in Korean literatures. OBJECTIVE: The purpose of this study was to review the clinical and histopathologic characteristics of rubella of 1996 outbreak. METHODS: We reviewed the clinical features and histopathologic findings in 50 patients diagnosed as rubella in Department of Dermatology, Presbyterian Medical Center from January 1996 through to May 1996. RESULTS: 1. The male-female ratio was 1: .17. The age distribution was 13-32 years and 72% of patients were aged 16-25 years. 2. Erythematous maculopapular rash on whole body was developed in all patients. Eighty two percent of the patients had fever and lymphadenopathy, and 36% of the patients had petechiae of soft palate. The main prodromal symptoms were sore throat(50%), headache(34%), and upper respiratory symptoms(22%), as order of frequency. 3. Positive serologic test for rubella IgM antibody was 79.5%. 4. The most common abnormal laboratory finding was leukopenia(58%), and followed by positive ASO(34%), the presence of atypical lymphocytes(21%), and thrombocytopenia(8%). 5. Histologically, epidermal changes were mild to moderate vacuolopathy(92.3%), the presence of dyskeratotic cells(30.8%), spongiosis(23.1%), and exocytosis(15.4%). Dermal findings were mild superficial perivascular lymphohistiocytic infiltration(100%), upper dermal edema(53.8%), perivascular edema(38.4%), pigmentary incontinence(30.8%), and the presence of extravasated RBC(23.1%). Eosinophil infiltration(15.4%) and the presence of large nucleated lymphocytes(92.3%) were also observed. Conclusions: According to the results of our study about rubella outbreak in 1996, clinical signs and symptoms were similar to those of previously described. Histologically, superficial perivascular dermatitis with mild to mederate vacuolar interface change was a main feature and large nucleated lymphocytes were frequently noted.

A 24 year old man presented a large keloidal patch on the posterior thigh with persistent purulent fistulae and comedones on it. Histopathological findings showed folliculoperifolliculitis with polymorphs, lymphocytes, plasma cells, multinucleated giant cells and hypertrophic sclerotic connective tiasue. Clinically and histopathologically the diasgnoais of folliculitis keloidalis was made, which is known to develop mostly on the posterior neck. The lesion was treated by surgical excision and skin graft.

A 25-year-old man had been intermittently treated with topical steroid ointment for his eczematous lesions on the scrotum. One year later, a few hard nontender nodules were found with surrounding thickened lichenified skin on the previous lesions. Histopathologic examination of the skin revealed moderate acanthosis of the epidermis and multiple scattered calcified materials in the upper demis and within the hair follicle. We present this case, being considered a dystrophic calcinosis cutis due to local injury.
