We studied 14 biopsies of congenital melanocytic nevi of children up to 1 year of age. In 11 biopsies we found two different types of melanocytic cells. In the reticular dermis, they were small cells. They had small nuclei, little cytoplasm, and no detectable pigment. They did not come in nests, but were scattered between the collagen bundles. The other(More)
Verrucous-keratotic forms of malignant melanoma occur more commonly in women and favor the extremities, but may occur on any anatomic site. Seventy-one percent of such melanomas are situated on the upper and lower extremities. Although two-thirds of these neoplasms can be assigned a histologic pattern according to the classification of Clark, one-third of(More)
The thickness of melanomas, presence or absence of ulceration, and the sex of the patient were the three dominant variables affecting the eight-year survival of 1,191 patients with clinical stage I melanoma in the prospective German melanoma group. With regard to these variables, three prognostic groups were defined representing 30%, 9%, and 61% of the(More)
Patients who died of a melanoma thinner than 1.5 mm within 96 months (group 1, n = 60) were compared with those having a tumor of the same thickness who had not died in this time period (Group 2, n = 300). Both groups were investigated with respect to differences in patient sex and age and to thickness, diameter, exophytic growth, and site of the melanoma(More)
In a study of 150 cases of malignant melanomas the histological variations of malignant melanoma of the superficial spreading type were observed. This type of malignant melanoma exhibits a variety of histological patterns. Beside the “pagetoid” distribution of rounded cells throughout all layers of the epidermis, a prominent distribution of cells along the(More)
Based on the recent clinical experience in treating florid oral papillomatosis (FOP), the only successful therapy appears to be the use of cytostatic agents. The case report of a patient with clinically and histologically confirmed FOP is described to emphasize the advantages of administering Bleomycin intra-arterially (external carotid artery) by means of(More)
Patients who died of a melanoma thinner than 1.5mm within 96 months (group 1, n=60) were compared with those having a tumor of the same thickness who had not died in this time period (Group 2, n=300). Both groups were investigated with respect to differences in patients sex and age and to thickness, diameter, exophytic growth, and site of the melanoma as(More)
BACKGROUND Diagnosis of an ulceratively decaying indolent papule in the skin of an AIDS patient. CASE REPORT In a 36-year-old HIV-positive man with a CD4 lymphocyte count of 60/microliters, a diagnosis of disseminated cryptococcosis was established based on a biopsy of an ulceratively decaying indolent papule in the skin of the left side gluteal region.(More)
There is general agreement that the thickness of a primary malignant melanoma is the most important prognostic factor [2, 13]. In recent years the thickness of excised melanomas has decreased [6, ~ 0, 11] due to the fact that tumors have been removed at earlier stages. A large proportion of tumors examined nowadays are less than 1.0 mm thick. However, in(More)
