Cigarette smoking, body mass index, and stressful life events as risk factors for psoriasis: results from an Italian case-control study.

We conducted a case-control study to analyse the association of psoriasis of recent onset with smoking habits, body mass index (BMI) and stressful life events. Cases (n=560; median age 38) were patients with a first diagnosis of psoriasis and a history of skin manifestations of no longer than two years after the reported disease onset. Patients with a new diagnosis of skin diseases other than psoriasis (n=690; median age 36) were selected as controls.

Malignant melanoma in a candidate for heart transplantation.

A superficial spreading melanoma (Breslow thickness 0.4 mm) was diagnosed in a 65-year-old candidate for heart transplantation due to refractory end stage heart failure. After extensive review of the literature (USA and Europe), no clear guidelines about the management of candidates for transplantation with a previous diagnosis of melanoma were found.

Primary cutaneous plasmacytoma after rejection of a transplanted kidney: case report and review of the literature.

Immunosuppressed organ allograft recipients are at risk of developing lymphomas and lymphoproliferative disorders as a consequence of immunosuppressive therapy and long-term antigenic stimulation from both the graft and possible viral infections. No more than 4% of the malignant tumors detected in organ recipients are plasmacytomas. Primary cutaneous plasmacytoma is a rare type of cutaneous B-cell lymphoma arising primarily in the skin.
