Bir Segmental Lentijinöz Olgusu

Segmental lentijinöz nadir görülen, vücudun bir yarısında segmental olarak yerleşen, normal görünümde deri üzerinde çok sayıda birkaç mm çapında lentigo makülleriyle karakterize bir tablodur. Çoğu kez deride sınırlı olmakla birlikte az sayıda nörolojik anormallik veya göz tutulumu gösteren olgular bildirilmiştir. Segmental lentijinöz klinik olarak başlıca nevus spilus ile ayırıcı tanıya girmekle birlikte zeminde pigmentasyon olmaması ve lezyonların deri seviyesinde olmasıyla nevus spilustan ayrılır. Burada klinik ve histopatolojik bulgular doğrultusunda segmental lentijinöz tanısı alan 15 yaşında bir olgu sunulmaktadır. Bu vesileyle segmental hipermelanozla seyreden tablolar gözden geçirilmiştir.

Segmental Lentiginous: A Case Report

Segmental lentiginous is a rare dermatosis placed segmentally on one half of the body and characterized by many lentigo macules which are a few mm in diameter, on the skin of normal appearance. Although often limited to the skin, a small number of cases with ocular involvement or neurological abnormalities have been reported. The main clinical differential diagnosis is with nevus spilus. It differs from nevus spilus with lack of pigmentation on the surface, and with the macular lesions not elevated from the skin. Here, we present a 15-year-old case diagnosed as segmental lentiginous in line with clinical and histopathologic findings We revised the tables presenting with segmental hipermelanosis on the occasion of this case.
