Sensitivity to estrogen has been described previously. The clinical picture is varied with pruritus, either generalized or localued or as urticaria. The hallmark of estrogen dermatitis is the cyclic premenstrual flare. The patient reported here had cyclic erythema multiforme-like lesions and showed a positive intradermal skin test to estrogen. A 20-year-old female patient presented with a periodic 5 year duration of skin lesions on both hands. The eruption commenced in the second half of the menstrual cycle, worsened through the luteal phase but the lesion almost disappeared during menstruation. An intradermal skin test to estrone showed positive results. However, a skin test with medroxyprogesterone acetate was negative. After systemic steroid and antihistamine therapy, the lesions were found to be significantly improved.

Median raphe cyst is a relatively uncommon lesion occurring in the midline male perineum, especially ventral aspect of penis. It is an embryologic developmental anomaliy of the male genitalia. Histologically, the lining cells are usually pseudostratified columnar epithelium, but can be stratified squamous epithelium and sometimes mucous glands and ciliated cells can be observed within the cyst wall. Herein, we report a case of median raphe cyst in the midline of the scrotum of a 2-year-old boy.

Immunohistochemial staining was performed in metastatic skin cancer using a variety of antistera. Both carcinoembrytonic antigen(CEA) and epithelial membrane antigen(EMA) were demonstrated in large cell carcinoma of the lung, adenocarcinoma of the stomach and skin adnexal cancer with eccrine differentiation. Although papillary carcinoma of the thyroid, squamous cell carcinoma of the skin and squamous cell carcinoma of the lung showed positive staining for CEA and EMA, these were weak or focal reactions in the keratinizing area. In rectal adenocarcinoma, staining for CEA was significantly positive, but staining for EMA was negative. Epiderrnal cytokeratin was observed in squamous cell carcinoma of the lung, squamous cell carcinoma of the skin and skin adnexal cancer with eccrine differentiation. Epidermal cytokeratin was also demonstrated in well differentiated adenocarcinoma of the gastrointestinal tract. By using a variety of tumor markers, the authors tried to locate possible primary sites in six metastatic skin cancers of unknown origin.

Hydroa vacciniforme is a rare, chronic photosensitivity disorder manifested in childhood by recurrent vesicles that hea1 with srarring. We report a case of hydroa vacciniforme in which vesicles were induced with multiple exposures ta UVA. The clinical features and ap-propriate laboratory evaluation of hydroa vacciniforme are reviewed.

Giant cell tumor (GCT) occurs very unusually in the rib (less than 1% of GCT). We present the cytologic features of GCT of the rib. It showed multiple cellular clusters composed of characteristic, benign looking osteoclast-like multinucleated giant cells and fibroblast-like mononuclear cells. The multinucleated giant cells contained numerous nuclei (average, 30 to 40 per cell, which were closely packed. The nuclei in giant cells were remarkably uniform and round to oval. The mononuclear, neoplastic stromal cells were elongated and spindle-shaped, There was no cytologically malignant portion in the tumor.

A 13-year-old girl developed rice to nut-sized, bluish to slate-gray colored, depressed patches in a zosteriform distribution along the right side of her upper back and arm without any symptoms. Microscopically, the lesions showed a normal-appearing epidermis, dermis, and subcutaneous fat tissue except for a thinning of collagen fibers and widening of intervals between them in the lower dermis. There have been no changes to the skin lesions during the last 2 years.

There is a wide array of designation for cutaneous vascular disorders based on clinical characteristics, histology, embryology, cellular biology, and hemodynamics. The cutaneous vascular disorders can be divided into hemangioma and vascular malformation according to the biologic classification based on cell kinetics i.e. endothelial hyperplasia. There are clinical and histologic differences between them. In this study, clinical, histologic and im-munohistochemical evaluations were attempted on 40 cases of cutaneous vascular disorders diagnosed the period between 1985 and 1993. The results are as follows: 1) Twenty-three out of forty cases were immunoreacive for proliferating cell nuclear antigen(PCNA). The lesions composed of capillary-sized blood vessels with endothelial hyperplasia were diffusely reactive, whereas those composed largely of dilated blood vessels with or without focal endothelial hyperplasia were only focally reactive. 2) Each groups of the classic classification contained both reactive and nonreactive cases except nevus flammeus and juvenfle hemangioma. 3) In contrast to the cases nonreactive for PCNA, those reactive for PCNA contained areas of proliferating small vessels, which showed reactivity for PCNA. In conclusion, the cutaneous vascular disorders diagnosed by the classic classification are heterogeneous in the pattern of the endothelial hyperplasia and the PCNA staining. Therefore it should be classified by the clinical and the histologic characteristics.
