The incidence of conjunctival melanoma is about 0.2–0.8/1 000 000 cases each year.1 2 As a consequence our knowledge about this tumour is limited, but cell lines derived from these tumours will give more information about them. So far only three conjunctival melanoma cell lines have been described.3 4 The first cell line, IPC 292, was described in 1993 by Aubert et al.4 Recently, Nareyeck et al developed two additional conjunctival melanoma cell lines (CRMM1 and CRMM2).3 We wish to report a further, fourth, conjunctival melanoma cell line, CM2005.1.

The conjunctival melanoma cell line CM2005.1 was established from tumour material derived from a 84-year-old male. The primary tumour was located at the medial side of the inner …
