X-linked recessive ichthyosis.

A 13-year-old boy presented with a lifelong history of tightly-adherent, brown, polygonal scales that covered the extensor surfaces of the extremities, lateral aspects of the trunk, and neck. The clinical presentation and the history of a similar skin condition in the patient's male maternal relatives helped establish the diagnosis of X-linked recessive ichthyosis (XLI). Systemic manifestations of the steroid sulfatase (STS) deficiency underlying XLI include cryptorchidism, asymptomatic corneal opacities, and maternal failure to progress during labor. Most cases of XLI are caused by deletions of the STS gene, and contiguous gene syndromes may occur when the deletions extend to neighboring genes on the distal short arm of the X chromosome.

Piebaldism.

A 46-year-old man presented with a history of a congenital pigment disorder. On physical examination hypopigmented and depigmented patches were present on the mid-forehead, anterior chest, and extremities. He also had loss of pigment of the medial eyebrows and a white forelock. The patient has a family history of a similar congenital pigment disorder, the pattern of which is indicative of the autosomal dominant disorder piebaldism.

Papulonodular mucinosis with subacute cutaneous lupus erythematosus.

A 30-year-old woman with subacute cutaneous lupus erythematosus presented with a facial eruption, painful and swollen ulcers of her digits, and asymptomatic lesions on her abdomen. The laboratory findings were consistent with subacute cutaneous lupus erythematosus with an anticardiolipin antibody. A biopsy specimen of the asymptomatic lesions on her abdomen showed mucin within the upper reticular dermis. Papulonodular mucinosis is a rare but well-documented finding associated with systemic and cutaneous forms of lupus erythematosus. The etiology and pathogenesis of this finding remain to be elucidated.

HDM2 protein overexpression and prognosis in primary malignant melanoma.

Overexpression of the oncogene HDM2 is observed in a substantial proportion of melanomas, including noninvasive and thin lesions, suggesting that HDM2 overexpression may be an early event in melanocyte transformation. To determine the role of HDM2 in the clinical progression of melanoma, we examined whether its expression was associated with patient survival. From November 1972 through November 1982, 134 patients with melanoma who participated in the New York University Melanoma Cooperative Group were studied, if representative tissues and follow-up were available. HDM2 protein expression was assessed immunohistochemically. Unexpectedly, we observed that HDM2 overexpression was statistically significantly associated with improved disease-free survival (relative risk [RR] = 0.47, 95% confidence interval [CI] = 0.24 to 0.89; two-sided chi(2) P =.021) and overall survival (RR = 0.55, 95% CI = 0.33 to 0.94; two-sided chi(2) P =.027) in multivariable analysis. HDM2 overexpression appears to be an independent predictor of survival for patients with primary melanoma; however, larger prospective studies are required for validation.

Evaluation of the proliferation marker MIB-1 in the prognosis of cutaneous malignant melanoma.

BACKGROUND: The proliferation marker MIB-1, which recognizes the Ki-67 antigen, provides independent prognostic information in several tumor types. Its utility in melanoma has been evaluated mostly in studies of thick primary tumors. Its usefulness in thinner lesions has not been assessed adequately. METHODS: A well characterized cohort of 137 patients diagnosed with primary cutaneous melanoma at the New York University School of Medicine between 1972 and 1982 was studied based on the availability of representative tissues and adequate clinical follow-up. Twenty-one tumors were less than or equal to 1.0 mm thick, 94 were between 1.01 and 4.0 mm thick, and 22 were thicker than 4.0 mm. Tumor cell proliferation was assessed by immunohistochemistry using the monoclonal antibody MIB-1. MIB-1 expression was correlated with baseline clinicopathologic parameters, as well as recurrence (RR), disease-free (DFS), and overall survival (OS) rates. Median follow-up among survivors was 6.5 years (range, 5.6-17.5). RESULTS: High proliferative index, defined as 20% or more of tumor cells showing nuclear immunoreactivity, was observed in 65 of 137 (47.4%) cases. High proliferative index was significantly correlated with increased tumor thickness (P < 0.001) and higher stage (P = 0.03). Trends approaching statistical significance were observed with ulceration of the primary tumor (P = 0.09), male gender (P = 0.06), and shorter DFS (P = 0.12). No significant associations were seen between high proliferative index and RR or OS. In multivariate analyses, tumor thickness was the strongest predictor of clinical outcome. CONCLUSIONS: In primary cutaneous melanoma, a high proliferative index is associated with clinicopathologic parameters predictive of worse clinical outcomes. However, it was not an independent predictor of clinical outcome.

Therapeutic decision making in the therapy of actinic keratoses.

Actinic keratoses (AKs) represent the second most common reason to visit a dermatologist in the United States and their therapy has become a major portion of most dermatologists' practice. An ever-increasing array of therapeutic options exist for the therapy of actinic keratoses, offering physicians and patients a greater number of choices than ever before. Patient expectations and needs seem to be changing at the same time, thus effecting therapeutic decision-making. While destructive therapies with resultant wounds, time for wound healing, and possible hypopigmentation or scarring were acceptable in the past, many patients from the baby-boom generation are now developing AKs and have little tolerance for any time for wound healing or any cosmetic changes. This paper will raise some fundamental questions regarding AKs and their management.
