Rare skin cancer: a population-based cancer registry descriptive study of 151 consecutive cases diagnosed between 1980 and 2004.

Background: There are few epidemiological data available on rare skin cancer, including Merkel cell carcinoma, Paget's disease, adnexal carcinoma, and sarcoma. We conducted this study to investigate the epidemiology of rare skin cancer diagnosed in the department of Doubs from 1980 to 2004.

Methods: Data were collected from a population-based cancer registry from 1980 to 2004.

Primary cutaneous lymphomas: a population-based descriptive study of 71 consecutive cases diagnosed between 1980 and 2003.

Although primary cutaneous lymphomas (PCL) are the second most common group of extra-nodal non-Hodgkin lymphomas, few epidemiological data are available in the literature, and most of them are provided by large databases from population-based cancer registries in the US or patients attending a single institution. We conducted this study to investigate the epidemiological and clinical features of PCL diagnosed in the department of Doubs from 1980 to 2003. Data were collected from the Doubs cancer registry from 1980 to 2003.
