Becker's nevus has been known as a sudden onset of hyperpigmentation on shoulder or arm in the second decade of life with slow peripheral extension and later development of hypertrichosis. We observed two cases of typical Becker's nevus which was confirmed by characteristicclinical and histopathological findings. One was 45-year-old male who has a patch of hyperpigmentation and hypertrichosis on left upper arm at birth, the other was 2()-year-old male who developed on right shoulder after sunburn which is a salient feature by Becker's initial description.

The effects of histamine type 2(H2) receptor antagonists, cimetidine and ranitidine, on the induction of contact hypersensitivity and UVB induced suppression of contact hypersensitivity were studied. Our experiment showed that treatment with cimetidine or ranitidine slightly enhanced contact hypersensitivity to DNCB, but the suppression of contact hypersensitivity elicited by UVB were moderatly reversed by ranitidine. These facts suggest that H2-receptor antagonist may be responsible for th blocking histamine induced suppressor factor by acting upon UV-induced suppressor T cell.

Human sparganosis is not uncommon and over 60 cases are reported in Korea but the case infested with multiple spargana is rare. The case we are reporting here is a 33 year-old Korean male having had an abscess and several bean-sized nodules on the left thigh. The patient had the history of eating frogs as a tonic food 3 years ago. Five spargana were removed from the lesions by surgical excision. Two of them were alive and other three were degenerated or calcified.

Fibrous papule of the face occurs nearly always as a solitary lesion on the face, especially on the nose. The lesion which appears as a dome shaped papule, is skin colored, pigmented or red, We present herein three cases of fibrous papule of the face, which developed on the ala nasi of 45-year-old man, and 49-year-old woman, and on the nostrile of 25-year-old woman. Histopathologic findings showed dermal angiofibrotic changes in two cases. In one of the two cases, there were atypical cells with large irregular nucleus and a few multinucleated giant cells interspersed in the edematous dermis, and there was distinct perifollicular fibrosis in the other case.

We report herein three cases of vesicular pemphigoid that is a varient of bullous pemphigoid, occuring in 38-year old female, 51-year old male, and 35-year old female patients. They had recurrent and moderate to severe pruritic tense vesicles with symmetrical distribution chiefly on the head and neck areas. The histological findings showed subepidermal bullae which contained a few eosinophils and the direct irnmunofluorescent tests revealed linear deposition of IgG, IgM and C, on the basement mernbrane zone. Futhermore, all the patients showed a good response to dapsone.

We report a case of acute graft-versus-host disease, which developed after bone marrow transplantation because of acute myelocytic leukemia in a 39-year old male, The pruritic, erythematous maculopapular eruptions began to developed on the perioral regions, and spreaded the face, the oral mucosa, both hands, and buttocks at the twenty fourth day after bone marrow transplanta.tion. The eruptions were confluent to form erythematous patches. Iistopathological findings show parakeratosis, lymphoid cell exocytosis, and papillary edema, lymphohistiocytic infiltration, and melanophage in the upper dermis, and basal vacuolation. He was treated systemically by methylprednisolone, and antilymphocytic globulin, and tapically by emollients and steroids.

We present a case of onychogryphosis of both great toe nails associated with onychomycosis of all toe nails occurring in a 90-year-old female patient. She also had senile dementia. Affected nail plates were thickened, increased in length, and curved like the horn of a ram. The nail plates were removed surgically form the nail bed. Direct microscopic examination revealed many hyphae with potassium hydroxide. Trichophyton rnbrum was isolated from the culture in Sabouraud glucose agar media. On histopathologic examination, we found many hyphae in the nail plate. We suggest an onychomycosis as one of the causes of onychogryphosis.

PURPOSE: To evaluate the significance of color Doppler ultrasonography in patients of chronic prostatitis. MATERIALS AND METHODS: We analysed the pattern of color Doppler images and quantitative changes of vascular flow and flow velocity parameters(FVP) using a 7.0 MHz transrectal probe with findings of expressed prostatic secretion (EPS) from 22 patients with clinically suspected chronic prostatitis and 12 controls with clinically suspected prostatodynia retrospectively. RESULTS: Compared with 2 groups according to color Doppler flow grade, higher grades(grade 2 or 3) of flow increase were more frequently seen in prostatitis group(54.5%) than in control group(33.3%)(p <0.05). But no significant difference was found in flow velocity parameter(FVP: maximal flow velocity, minimal flow velocity, resistive index, and pulsatility index) between control and prostatitis group. Two months later follow up ultrasonography of 5 cases in the prostatitis group after treatment, all of 5 cases showed decrease the color Doppler flow compared with the initial color Doppler image grade. CONCLUSIONS: Grading of the amount of color flow with Doppler ultrasonography is of limited significance at efficacy decision after treatment in chronic prostatitis. But precaution should be taken to use color Doppler ultrasonography as objective diagnostic tool, although higher grades of flow increase were more frequently seen in prostatitis group than control group.
