Perforating folliculitis in association with primary sclerosing cholangitis.

Two patients with primary sclerosing cholangitis developed perforating lesions in the skin of the extremities. Clinically and histologically, the cutaneous condition showed the features of perforating folliculitis with superimposed lesions of prurigo nodularis. The course of the eruption paralleled the severity of the biliary disease. A theory of pathogenesis for the development of the perforating folliculitis in these patients is suggested. To the best of our knowledge, this is the first report of the coexistence of both conditions.

Reactive perforating collagenosis.

Seven patients with reacting perforating collagenosis (RPC) were diagnosed from 1974 to 1982. Experimental production of lesions in two patients confirmed the contributory role of superficial trauma. The pathogenesis of RPC involves transepithelial elimination of altered collagenous bundles. This process may be observed in a wide variety of disparate skin diseases.

Urticaria and fixed drug eruption in a patient treated with griseofulvin.

We report a case of urticaria and fixed drug eruption ( FDE ) caused by griseofulvin. Although griseofulvin-induced urticaria is well documented, FDE secondary to griseofulvin is distinctly uncommon. Moreover, the appearance of urticaria and FDE in the same patient following treatment with griseofulvin is, we believe, the first to be described in the literature. The concept of FDE is briefly reviewed.

Metastases of thin melanomas.

Although thin malignant melanomas, i.e., those less than 0.76 mm in thickness, of the skin generally do not metastasize, it has been recently reported that when histologic regression is present, such lesions may then have a greater propensity for dissemination. However, this was not apparent in this study in which only one melanoma metastasized in a consecutive series of 41 thin lesions which were step-sectioned and had evidence of regression histologically. Possible explanations for this discrepancy are the failure of other authors to include only step-sectioned specimens of the primary melanomas in their material and/or geographic differences in the biologic behavior of this malignant neoplasm.

Regression in malignant melanoma.

A multiple stepwise logistic regression analysis shows that histologic regression is more likely to be found in a malignant melanoma that is level III or less, more than 10 mm in diameter, associated with solar elastosis, located on an anatomic area other than the head or neck, and when there are areas of whiteness clinically. Although patients with malignant melanomas displaying signs of regression histologically have a slightly better 5-year disease-free survival, this may be attributed to a difference in tumor thickness.

Steatocystoma multiplex.

A family with a four-generation history of steatocystoma multiplex is presented. The subject described had unusually large tumors on his scalp and forehead which were successfully excised and closed with skin grafts.

Favorable prognosis for malignant melanomas associated with acquired melanocytic nevi.

In a clinicohistopathologic study of 557 patients with primary cutaneous malignant melanoma, there were fewer metastases and/or deaths from melanoma when histologic evidence of a coexisting acquired melanocytic nevus was found. A total of 130 patients with melanocytic nevus and 427 cases of melanoma without histologic evidence of a nevus (denovo) were studied. Clinical follow-up evaluation for evidence of metastases and/or death was obtained. Only ten of the patients (7.7%) with nevus-associated melanoma had metastases and/or death v 78 (18.3%) with de novo melanoma. When stratified by lesion thickness, the logrank test for survival revealed a statistically significant difference between the two groups. An overall favorable outcome seen in patients with malignant melanomas associated with acquired melanocytic nevi was found, therefore, to be independent of lesion thickness as well as six other variables reported to be related to the biologic behavior of malignant melanoma. Thus, the presence of nevus cells in a specimen of malignant melanoma portends a better prognosis and may have important implications in the biology of this neoplasm.
