1.Four Cases of Keloid.
Annals of Dermatology 1997;9(1):59-63
Keloid is a hyperproliferative disorder of dermal connective tissues, that sometimes causes perplexy and cannot be managed with medical therapy alone, such as intralesional corticosteroids or interferon injections. In those cases, the best results can be obtained when medical therapy is combined with surgical therapy. Four cases of keloid that had been successfully treated with surgical keloidectomy and postoperative adjunctive therapy are herein reported.

We experienced a case of venous hemangioma occuring on the inner aspect of right forearm of 40-year-old woman. The skin lesion was slight tender, pea sized, dark brown surfaced, subcutaneous mass. The entire dermis was filled with numerous coiled thick walled vessels surrounded by fibrous stroma on the histopathologic examination. The wall, lined by a single layer of endothelial cells, lacked elastic fibers on the specimen of Verhoeff-Van Gieson and Massons trichrotne stains.

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 distribution of pemphigus subclass autoantibodies in a patient with pemphigus vulgaris (PV) has been investigated by semiquantitative indirect immunofluorescence (IIF), using the HP series monoclonal antibodies specific for four human IgG subclasses on human foreskins. IgG1 and IgG4 intercellular substance-specific autoantibodies were detected in the serum of the patient, whereas IgG2 and IgG3 autoantibodies were absent. In addition to foreskins, human tonsillar epithelia were used as substrates of IIF for detecting the PV autoantibodies and it was one of satisfactory substitutes for monkey esophagus.

Extramammary Paget's disease is a rare malignancy occuring mainly in apocrine gland- bearing areas such as vulva, scrotum, perianal area, and axilla. Histopathologically, the Paget's cells are usually confined within the epidermis and may be associated with underlying adenocarcinoma. Although surgical excision is the treatment of choice, the clinical demarcation of the lesion is still a frequent problem in the treatment of extramammary Paget's disease. We tried photodynamic diagnosis to determine the surgical margin of extramammary Paget's disease and with surgical excision guided by photodynamic diagnosis successfully treated two cases.

BACKGROUND: Photodynamic therapy(PDT) is a kind of non-invasive photochemotherapy, which is designed to kill the target cells through photodynamic reaction. It has been reported that PDT is very effective in superficial lesions, including extramammary Paget's disease. Yet, there has been no clinical trial for the treatment of extramammary Paget's disease using PDT in Korea. OBJECTIVE: The purpose of this study was to evaluate the effectiveness of PDT in treating extramammary Paget's disease METHOD: Seven patients with anogenital extramammary Paget's disease were treated repeatedly with local PDT using topical ALA 20% and intralesional injection of hematoporphyrin derivative (HpD), and systemic PDT using HpD. Fluences of 125-200J/cm2 and intensities of 50-100mW/cm2 were used. RESULT: The clinical outcomes were disappointing. All the patients experienced only partial responses despite repeated treatments. But side effects were minimal. CONCLUSION: PDT is not effective enough for the treatment of extramammary Paget's disease to be used as a primary therapy. It would be better to use as an adjuvant to other treatment methods. Photodynamic sensitization, also known as photodynamic diagnosis, might help us define a more reliable border of the extent involved and the surgical margin to be excised.
