Pseudolymphoma of the earlobes due to ear piercing.

Keloids are commonly seen as a complication of earlobe piercing. As biopsies are usually not performed routinely in many instances, some of the lesions might, in fact, represent other entities, such as cutaneous pseudolymphoma. Contrary to keloids, for which surgery alone is not recommended, a simple excision or superficial x-ray is sufficient in such cases.

Subacute cutaneous lupus erythematosus associated with breast carcinoma.

A case of subacute cutaneous lupus erythematosus associated with breast carcinoma is presented. The patient had not been aware of her malignant disease and had consulted us after her dermatosis developed. To date only one case of subacute cutaneous lupus erythematosus associated with malignancy has been described in the literature. The relationship between a dermatosis and a malignant internal disease is discussed.

HTLV-I-associated T-cell leukemia/lymphoma in Israel.

Human T-cell lymphotrophic virus Type I (HTLV-I)-associated adult T-cell leukemia/lymphoma (ATL) is a relatively new clinical entity. The disease is endemic in southwestern Japan, the Caribbean basin, the southeastern United States and Africa. We report the identification of this disease in Israel and review previous cases of HTLV-I infection and ATL in this region. The disease was initially indolent and later clinically aggressive, characterized by hypercalcemia, osteolytic bone lesions, leukemic skin and organ infiltration and opportunistic infection.

Antigen-stimulated lymphokines from patients with cutaneous leishmaniasis induce monocyte killing of Leishmania major intracellular amastigotes.

The specific immune response of patients with cutaneous leishmaniasis including the ability of their lymphokines to enhance the monocytes' leishmaniacidal activity was studied. In 16 patients with cutaneous leishmaniasis, their concanavalin A-induced lymphocyte proliferative responses, interferon-gamma and interleukin 2 activities and the ability of their concanavalin A-induced lymphokines to kill monocyte intracellular amastigotes were not different from normal controls. Antigen-stimulated lymphocyte cultures showed that 13 of 13 patients had an increased lymphocyte proliferative response; 11 of 16 produced interleukin 2 and 12 of 13 produced interferon-gamma; in addition, 10 of 11 of these antigen-induced supernatants increased the monocytes' killing of Leishmania major amastigotes. Antibody levels to parasite membrane antigens determined by radioimmunoassay showed that 8 of 13 titers were greater than 10 and 4 of 13 titers were 2 to 10 times higher than control. Our findings demonstrate that patients with cutaneous leishmaniasis elicit a specific immune response to L. major antigens and part of this response is the production of lymphokine capable of promoting monocyte killing of intracellular amastigotes.

Sarcoidosis versus foreign-body granulomas.

A 42-year-old man developed a papulonodular exanthema 10 years following an injury from a shell explosion. The differential diagnosis between sarcoid-like, foreign-body granulomas and Boeck's sarcoid was inconclusive by histology, but x-ray spectroanalytic examination revealed silicon particles within the epitheloid cell granulomas.

Topical application of human fibroblast interferon (IFN) in cutaneous leishmaniasis.

Fifteen patients with single or multiple lesions of cutaneous leishmaniasis were randomly assigned to apply either IFN-beta-containing cream or a placebo cream base. Despite 8 weeks of therapy no significant improvement of the lesions was achieved. Although topical IFN-beta was not effective in this study, several laboratory studies suggest that IFN, particularly IFN-gamma, may be of therapeutic value in cutaneous leishmaniasis.

Neutrophilic dermatosis and myelodysplastic syndrome.

Acute febrile neutrophilic dermatosis (AFND) is sometimes associated with leukemia. We present a patient with myelodysplastic syndrome who subsequently developed AFND, and we briefly review the association of AFND and myeloproliferative disorders.

Pseudomelanoma following laser therapy for congenital nevus.

Benign nevi can be removed by a variety of procedures including surgical excision, electrocautery, slicing off the protruding portion by a shave biopsy, cryotherapy, dermabrasion, etc. Except in the case of complete excision, these procedures may often be followed by recurrence. We describe a congenital nevus that was incompletely removed by CO2 laser therapy. When the lesion recurred, it had clinical as well as histologic features in common with malignant melanoma, although it was completely benign.
