A 23-year-old woman was presented with a prolonged history of a small lump in the buccal mucosa. A local excision was performed. The morphology diagnosed a Spitz nevus and she underwent supplementary excision of scar tissue. Two years later a submandibular lump appeared on the ipsilateral side of the neck. Cytology from fine needle aspiration indicated spread of a melanocytic tumor and she underwent a modified supraomohyiod neck dissection. One of the lymph nodes showed an inclusion of cells in the deep layers with epitheloid and spindle cells in a pattern similar to that of the primary oral lesion. The finding suggests a mechanical spread of melanocytes from the Spitz nevus to the regional lymph node. After more than 3 years of follow-up there is no further manifestation of disease. It is believed that this may be an example of how a Spitz tumor, although inherently benign, can spread along lymphatics in a pseudometastatic fashion. To our knowledge this is the first report of an oral Spitz melanoma with metastatic behavior.

ABSTRACT: The treatment of congenital melanocytic naevi (CMNs) has become controversial as better data on complications have been published. To determine the longer-term risks and benefits of surgery in treatment of CMNs. In this 19-year prospective study, 301 families completed yearly questionnaires about treatments and CMN changes. Forty per cent of CMNs were > 20 cm projected adult size (PAS) or multiple CMNs. Girls were more likely to have had surgical treatments. There were no significant effects of treatment on the incidence of adverse clinical outcomes, although the numbers for melanoma were small. The majority of untreated CMNs lightened spontaneously during the follow-up period. Surgical treatment and satellites at birth were independently significantly associated with reported darkening of the CMN over the follow-up period. However there was no absolute measurement of final colour. Surgical treatment was associated with decreasing hairiness of the CMN over the follow-up period. PAS was associated with increasing hairiness. Excision with tissue expanders and PAS were significantly associated with an increased incidence of new satellite lesions. A proportion of patients reported new pigmentation in previously unaffected skin at the edge of a treated area, the majority after complete excision. There was a high level of satisfaction with surgery in the < 20 cm group and in those with facial CMNs. This was significantly reduced with increasing PAS. There is no evidence here that surgery reduces the incidence of adverse clinical outcomes in childhood. The natural history of the majority of untreated CMNs is to lighten spontaneously, whereas some treatments may cause adverse effects.British Journal of Dermatology 10/2008; 160(2):387-92.

ABSTRACT: Recent advances in research have prompted this review of the role of surgery in the management of congenital melanocytic naevi (CMNs). Good data on the incidence of neurological and malignant complications of CMNs have re-fuelled the debates on whether surgery decreases the risk of malignant melanoma and whether early surgery is advantageous. We conclude the following: 1) untreated CMNs can lighten spontaneously, sometimes dramatically, 2) routine surgery has not been demonstrated to reduce the risk of malignancy and is, therefore, for cosmetic reasons only, 3) early surgery has not been shown to be advantageous and carries increased anaesthetic risk and 4) there is some evidence that surgical intervention may adversely affect the behaviour of the CMN cells. Our current practice is based on the following guidelines: 1) patients are treated in a multidisciplinary-team setting which includes the specialties of paediatric dermatology, plastic surgery and neuroradiology with access to neurology, neurosurgery and oncology, 2) serial photographs are taken at yearly intervals to assess spontaneous lightening. 3) all routine surgery is delayed for at least the first year. 4) patients with facial CMNs (either the principal lesion or large satellites) are offered surgery for cosmetic reasons, 5) patients with a single, easily excisable CMN are offered surgery for cosmetic reasons and 6) all families are made aware of the possibility of spontaneous lightening and the possibility that surgery may have effects on the behaviour of naevus cells.Journal of Plastic Reconstructive & Aesthetic Surgery 03/2009; 62(5):595-601.
