Rapid growth and slow involution of Reed nevus in a long-term dermoscopic follow-up.

We describe the rapid growth of a Reed nevus followed by its slow involution and present dermoscopic follow-up images. The child was monitored for 10 years (from age 3 to 13 years) by digital dermoscopy. The Reed nevus completely lost its typical dermoscopic arrangement (starburst pattern) with involution and distinct changes in dermoscopic pattern.

Clinical-Dermoscopic-Histopathological Correlations in Collision Skin Tumours.

Objectives: Collision tumours are rare situations characterised by the coincidence of two different skin neoplasms in the same lesion.

Methods: We have analyzed 41 collision skin tumours from one department in the clinical-dermoscopic-histopathologic correlations.

Results: We present 41 collisions tumours.

The use of 2940-nm ER:YAG laser for the treatment of lentigo maligna.

Objectives: Lentigo maligna is a common in situ malignancy in elderly patients, with a low risk of progression to an invasive tumor. Surgical treatment may be complicated or refused. Non-surgical treatment options (such as lasers) may therefore be needed.
