Kissing nevus (KN) is a rare type of congenital melanocytic nevus that occurs in contiguous areas of the body that are divided during embryogenesis [1]. Although it usually appears on the eyelids, involvement of other locations such as the fingers or penis has been described. Dermoscopic findings of KN are non-specific and include a symmetrical globular pattern and globular-reticular pattern with a fine pigment network at the periphery and symmetrical globules in the centre [2, 3]. The appearance of areas without structures or the presence of various colours, especially blue, white or grey, suggest malignancy, and mucosal melanoma should be ruled out [4]. Histopathological examination usually demonstrates intradermal proliferation of small melanocytes with a highly pigmented dermis and numerous melanin-containing dermal melanophages. Significant cytological atypia are not observed. Based on these findings, KN is frequently diagnosed as an intradermal melanocytic nevus [5]. Although the risk of malignancy of KS is low, surgical treatment is recommended in suspicious cases and in those in which excision does not result in significant morbidity [1, 5]. Due to the impossibility of retracting the foreskin of our patient, a postectomy was performed for better follow-up. Histological findings of the foreskin specimen confirmed the suspected diagnosis.
