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. Seventy-one patients with PCL were investigated. 82% were cutaneous T-cell lymphoma (CTCL) and 18% were cutaneous B-cell lymphoma (CBCL). Among CTCL, mycosis fungoides (MF) represented 58% and Sezary syndrome 10%. The standardised incidence rate of PCL was 0.42 for 100 000 person-years and significantly increased from 0.21 in 1980-1984 to 0.70 in 2000-2003 (p <0.05). The incidence rate of CTCL was 0.34 for 100 000 person-year and significantly increased from 0.2 to 0.57 (p <0.05). For MF and CBCL, the incidence rates were 0.20 and 0.08, respectively and did not vary significantly from 1980-1984 to 2000-2003. Five-year survival was 64.5% for PCL patients similar to MF patients. Our results provide updated data on the incidence of PCL in France.

Cutaneous lymphomas are lymphoproliferations affecting skin only at the time of diagnosis. There are two major types, B-cell lymphomas and T-cell lymphomas, which prognosis depends of histological subtype and staging evaluation. In cutaneous B-cell lymphomas, there are two indolent subtypes (primary cutaneous marginal zone B-cell lymphoma and primary cutaneous follicle center lymphoma) and one more aggressive type (primary cutaneous diffuse large B-cell lymphoma, leg type). Classification of T-cell lymphomas distinguishes indolent subtypes such as mycosis fungoides, the most frequent of T-cell lymphomas, and CD30+ lymphoproliferations such as lymphomatoid papulosis, whereas other T-cell lymphoma subtypes have a more pejorative prognosis such as Sezary syndrome (erythrodermic and leukemic form of mycosis fungoides) and CD30- lymphomas. Staging evaluation with CT-scan of chest, abdomen and pelvis, bone marrow examination if necessary and lymph node biopsy if palpable node over 1 or 1.5 cm diameter, is necessary for therapeutic decision.

Cutaneous T-cell lymphoma (CTCL) is the most frequently encountered type of skin lymphoma in humans. CTCL encompasses multiple variants, but the most common types are mycosis fungoides (MF) and Sezary syndrome (SS). While most cases of MF run a mild course over a period of many years, other subtypes of CTCL are very aggressive. The rapidly expanding fields of proteomics and genomics have not only helped increase knowledge concerning the carcinogenesis and tumor biology of CTCL but also led to the discovery of novel markers for targeted therapy. Although multiple biomarkers linked to CTCL have been known for a relatively long time (e.g., CD25, CD45, CD45RA, and CD45R0), compared to other cancers (lymphoma, melanoma, colon carcinoma, head and neck cancer, renal cancer, and cutaneous B-cell lymphoma), information about the antigenicity of CTCL remains relatively limited and no dependable protein marker for CTCL has been discovered. Considering the aggressive nature of some types of CTCL, it is necessary to identify circulating molecules that can help in the early diagnosis, differentiation from inflammatory skin diseases (psoriasis, nummular eczema), and aid in predicting the prognosis and evolution of this pathology. This review aims to bring together some of the information concerning protein markers linked to CTCL, in an effort to further the understanding of the convolute processes involved in this complex pathology.
