Intravascular papillary endothelial hyperplasia is a relatively rare benign tumor, which is charaterized by the development of endothelial-lined papillary projections in a vascular lumen. They can occur as a pure form in which endothelial proliferation developes in a dilated vessel, a mixed form in which endothelial proliferation occurs within a pre-existing angioma. We herein report a case of intravascular papillary endothelial hyperplasia coexistent with angioleiomyoma occuring in a 54-year-old man, who had a slowly growing tumor on the right sole for 2 years. The histologic findings revealed a solitary encapsulated mass composed of smooth muscles and blood vessels in deep dermis and papillary endothelial hyperplasia in a neighboring blood vessel.

Porokeratosis is a specific disorder of keratinization characterized histologically by the presence of a cornoid lamella. Clinically, the basic lesion is a sharply demarcated hyperkeratotic plaque which may be linear, punctated, or annular with central atrophy. The etiology of the various types of porokeratosis is unknown. However, heredity, UV radiation, immunosuppression, trauma, burns, and occult infection are known to be precipitating or exacerbating factors. A 32-year-old female was burnt on her right arm and chest at the age of 12. Several years later, brownish plaques developed in these burn areas. Seven years prior to visiting our clinic, nu- merous match-head sized, peripherally elevated macules developed on the forearms and have gradually spread to the other areas of her upper and lower extremities. The histological findings of two lesions from the burn areas showed the same features including cornoid lamellae in the epidermis and fibrosis in the dermis. Howerer, the histological finding of a lesion from a non-burn area showed cornoid lamellae in the epidermis without evidence of dermal fibrosis. We believe our case is the first to be reported in Korea in which porokeratosis arose in previous burn areas. (Kor J Dermatol 1997;35(2): 396-400)

Cribier and Grosshans(1995) reported two cases of tumor of the follicular infundibulum(TFI) arising in nevus sebaceus for the first time. In 1961 Mehregan and Butler described a new benign adnexal neoplasm, which they called t,umor of the follicular infundi4ulurn. Since then few observations have been published. The majority of the lesions are solitary. They appeared in adults, predominantly in wornen, on the face, arm, and neck. Histopathologically, the unique feature is a benign hyperplastic lesion that extends from the follicular infundibuluni. as an epithelial plate either with underlying elastic fiber network in TFI or without underlying elastic fiber network in TFI like change. A 52-year-old man has haf a solitary, well-defined, hairless, verrucous plaque on his right supra auricular area for about 10 years. It has seerned to increase gradually in size over the last year. The histologic findings shwed a plate-like growth of epithelial cells in the upper dermis extending parallel to the epidermis with multiple connections at the lower margin of the epidermis. The peripheral cell layer of ttie tumor plate showed palisading, and centrally located cells were pale staining. Many hair follicl s, mature sebaceous glands, ectopic apocrine glands, and inflammatory cell infiltrations were present in the dermis. However, there was no elastic fiber network beneath the epithelial cell plate. We believe our case is the first to be reported in Korea as TFI-like change in nevus sebaceus.

Background: CD34 is a 115 kD glycoprotein which is expressed on hematopoietic progenitor cells. It is also known as an immunohistochemical marker of endothelial cells. Objective : This study was designed to investigate the patterns of CD34 expression on: (1) cutaneous benign and malignant vascular tumors and (2) on the mature and immature vessels of pyogenic grauloma and capillary hemangioma. Method: We performed immunoperoxidase staining using a monoclonal anti-CD34 antibody (QBEND/10) on formalin fixed, paraffin-embedded sections of 23 benign and malignant cutaneous vascular tumors. Results : The results are summerized as follows: 1. In 3 cases of nevus flammeus and 6 cases of carvernous hemangioma, vascular endothelial cells of all hemangiomas showed CD34 expressions. In 5 cases of angiokeratoma, endothelial cells of hemangioma, did not express CD34. 2. In all 5 cases of pyogenic granulomas and one case of capillary hemangioma, endothelial cells of mature vessels, endothelial cells near the well-formed lumina and endothelial cells showing intracellular lumina showed strong positivity for CD34, wbile endothelial cells far from the lumina and endothelial cells without lumina formation mostly showed negative staining for CD34. 3. One cese of Kaposis sarcoma showed focall positivity for CD34 both in endothelial cells of the small, well-formed vessels and spindle cells. Two cases of angiosarcoma showed CD34 expression only in endothelial cells of well-formed, normal appearing vessels, whereas atypical endothelial cells of tumor vessels and spindle cells were negative for CD34. Conclusion : CD34 could be a marker for endothelium in mature, well-differentiated vascular structures and may serve as a marker of lumen formation or differentiation of endothelial cells.

Background: Pilomatricoma is a rare benign follicular tumor in Orientals. Objective : Clinical and histopathological features of the tumor were analyzed. Methods: The medical records and histopathological slides of 19 tumors from 17 patients with pilomatricoma were studied. Results : The morphology of the tumors were divided into 3 groups :1) elevated, uniform nodules(16 cases), 2) elevated, multilobulated nodules(2 cases), and 3) non-elevated, uniform nodules (1 case). Histologically, the tumors were composed of shadow cells, transitional cells, basaloid cells and squamous cells. Changes of the stroma within the tumors and the stroma overlying the tumors included vascular dilatation, RBC engorgement and infiltration of inflammatory cells. Changes of the epidermis overlying the tumors were found in 14 cases and included hyperkeratosis(14 cases), follicular plugging(2 cases), epidermis invagination(5 cases) and acanthosis nigricans-like change(3 cases). Conclusion: Clinically, pilomatricomas manifested as either a solitary nodule or two nodules. Histologically, several tumors showed palisading of basaloid cells, retraction spaces, lymphoid follicles and acanthosis nigricans-liike epidermal changes in addition to the classic features of pilomatricoma.

Cinnamic Aldehyde에 의한 색소성 접촉피부염의
이상훈 ( Sang Hun Lee ),백용관 ( Yong Gwan Baik ),신자경 ( Ja Gyeong Shin ),이호균 ( Ho Gyun Lee ),김종민 ( Jong Min Kim ) 대한피부과학회 1996 대한피부과학회지 Vol.34 No.3
Pigmented contact dermatitis denotes a kind of secondary hyperpigmentation resulting from recurrent contact dermatitis of low degree. Cinnamic aldehyde is a component of cinnamon,which is widely used in foods and fragrances. A 21 year-old girl presented with a well-defined dark brownish patch on right side of chest for 4 years. Histopathologic examination revealed epidermal spongiosis, hypermelanosis of basal layer, scattered melanophages and mild perivascular inflammatory cell infiltration in the upper dermis. Patch test findings were positive to fragrance mix, cinnamic aldehyde and body shampoo which was used by the patient. Peroral challenge with cinnamon tea resulted in flare-up of the positive patch-test sites and the skin lesion. (Kor J Dermatol 1996;34(3): 468-471)
