BACKGROUND: Beckers nevus is a benign lesion that may be congental or acquired, macular or papular, hairless or hypertrichotie. OBJECTIVE: Our pcrpose was to describe the clinical findings of Eeckers nevus and to establish a method for the histologic diagnosis of Beckers nevus. MEHTODS: We reviewed PF skin biopsies and their clinical finding from 28 patients with Beckers nevus during a 10 year period from January 1981 to January 1991. Results : The results were summarized as follows. A Clinical characteristics 1. Sex distribution showed of male predominence with male female a ratio of 1.5:1. Age of onset was predominent in less that 5 years old and puberty. 2. The lesions were located on the trunk(24 cases), head & neck(8 cases), extremities(6 cases), and were repsilateral in 26 cases, bilateral in 2 cases. 3. The lesions were accompanied by hair in 17 cases(61%). The shaies of the lesions were reticulated (75 %), patch(18%), mottled(7%). 4. Hairs were distributed as follows : abdomen(100%), scapula(100 %), extremities (83%), cheek(80 %), neck(67 %), chest(40%). All lesions of the face had follicular papules. 5. Associated skin diseases were : smooth muscle hamartoma(3 cases), striae distensa(2 cases), steroid acne(2 cases), pigmented nevus(2 cases), and verruca plana(1 case). B. Histopathologic characteristics 1. The lesions were accompanied with plugs in 21 cases, which were follicular, acrosyringeal, epidermal. 2. Elongation of the rete ridge and hyperpigmented basal cells were observed in the epidermis in all cases. 3. The shape of the rete ridge in Beckers nevus has its characteristic appearance, which is single, bridging and reticulated. Single, bridging and reticulated shapes cexisted in 17 cases(61%). 4. Inflammatiry cell infiltrations were present in all of the upper drmis, in which melanophages(21 %), hair follicles(89%) and smooth muscle hamartoma(3cases) w ere observed CONCLUSION: These findings indicated that the shape of the rete ridge in Beckers nevus has its characteristic appesrance and can be useful for the diagnosis of Beckers nevus.

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%).

Yellow nail syndrome is characterized by yellow discoloration of nails, chrnnic lymphedema and respiratory dieorders such as chronic bronehitis, bronchiectasis, pleural effusion and chronic sinusitis. Other changes of nail in this syndrome are the exaggerated lateral curvature and disappearance of lunula and cuticle. These nail changes are caused by greatly slow nail growth than in normal due to the defective lymphatic drainage. We report a case of yellow nail syndrome in a 55 year-old woman who has pulmanary edema, congestive heart failure for 3 years, and yellow naiIs of all fingers and toes for 1 year.

Nodular pseudosarcornatous fasciitis is a benign, fibrohlastic proliferative disease. This case report is one of a hard nodule which a 35-year-old male suddenly discovered on his right forearm 10 days prior to being aeen. The nodule showed characteristic histological findings of nodular pseudosarcomatous fasciitis.

Oil granuloma develops mainly after injection of oil substances such as paraffin, silicone, etc, but there have been reports of oil granuloma after topical application of lipid substance to the body. A 22-year-old woman developed oil granuloma after the application of squalene on both lower eye-lids. Histopathologic findings ahowed acanthosis and dyskeratosis of the hair follicles. Lipid suketances staining with oil-red-O stain were found mainly on the hair follicles. and partly on the epidermis. We report a case of oil grinulorna caused by squalerie that may have penetrated through the hair follicles and partly through the epidermis resulting in chronic granulous changes in the dermis.

22 cases of giant cell tumor of bone treated between 1973 and 1979 have been reviewed after a miaimum follow-up of two years and following results were obtaind. 1. Fourteen cases (63%) were in the third and fourth decade. 2. Fourteen cases (63%) were located around the knee joint. 3. Five (42%) of the twelve tumors treated by curettage and bone graft recurred. Five tumors treated by En bloc resection and two tumors treated by amputation had no recurrences. 4. Five of six recurrences occured within two years after mitial treatment.

We report a case of papillary eccrine adenoma occurring in a 39-year-old male who had a walnut sized, firm nodule on the right knee without subjective symptoms. Histopathologic exammination revealed a well circumscribed, non-capsulated dermal nodule consisting of multiple ducts with various sizes. These ducts were composed of double layered epithelial cells in most areas, but in some areas severe intraluminal papillation snd pseudostratification into the lumen were seen and the lumina were filled with a homogenous eosinophilic substance and partially with calcium deposition. Immunohistochemical studies with S-100 antigen and csrcinoembryonic sntigen (CEA) were also performed. Positivity for these sntigens strongly supports the hypothesis that this unusual neoplasm differentiates toward the eccrine secretory coil.
