[Progressive peripunctal nevus in an adult].
Nevi arise from migration of melanocytes into the epithelium. Over the years they experience a typical maturation, with the possibility of an increased thickness due to accompanying inflammation or fibrosis but actual growth of nevi is rare in adults. A 70-year-old patient presented with a growing tumour around the punctum lacrimale. The histological examination revealed a conjunctival nevus without any transformation. Peripunctal nevi are rare. The localisation of a nevus in the area of the punctum lacrimale was first published in 1931 and only 10 other patients with such a nevus have been reported. If at all, an enlargement of a peripunctal nevus has been described in younger patients. The patient presented here showed significant growth of the nevus at an atypically high age without any histological signs of malignancy or proliferation. The reason for this uncommon nevus enlargement remains unclear.
