[Primary cutaneous cryptococcosis in HIV-seronegative subjects].

Background: Primary cutaneous cryptococcosis is an uncommon clinical entity characterized by direct skin inoculation without systemic involvement. We report four cases of this affection in HIV-negative patients seen between 1990 and 1999 in Nantes Dermatological Clinic.

Case Reports: Patients mean age was seventy.

[Viruses involved in allograft recipients'cutaneous carcinomas].

Background: Cutaneous carcinomas are frequent in renal allograft recipients. Their treatment can be difficult especially in cases of multiple carcinomas. The aim of this study was to determine whether human papillomavirus are more frequent in patients group with multiple cutaneous carcinomas and whether other viruses such as Epstein-Barr virus, cytomegalovirus, and herpes simplex might be associated in this kind of tumour.

Primary cutaneous B-cell lymphomas of the lower limbs: a study of integrin expression in 11 cases.

Primary cutaneous B-cell lymphoma is a rare disease. Among the cutaneous B lymphomas, B-cell lymphomas of the lower limbs appear as a special subgroup with a prognosis that is possibly worse than that of primary cutaneous B-cell lymphomas located on the trunk, arms or head, with more frequent relapses. In addition, some recent studies indicate that the level of expression of integrins on tumour cells could be related to the clinical course of the disease.

[IgM kappa lymphoma with antisulfatide antibodies revealed by cervical motor neuropathy simulating amyotrophic lateral sclerosis].

Introduction: It is well known that polyneuropathy is associated with monoclonal IgM kappa.

Exegesis: We report the case of a 79-year-old man with lymphoma and motor neuron disease at cervical level simulating amyotrophic lateral sclerosis (ALS). Neurological deficit with inflammatory process evolved within 4 months.
