The Immunohistological Features of Acquired Bilateral Nevus of Ota-like Macules: Comparison with Melasma and Nevus of Ota
BACKGROUND: Acquired, bilateral nevus of Ota-like macules (ABNOM) is characterized by blue-brown macules on the face. The precise pathogenesis is unknown but reactivation of preexisting immature dermal melanocytes has been suggested for the cause of ABNOM. ABNOM is similar to melasma in clinical …

Histopathologic and Immunohistochemical Characteristics of Becker's Nevus
BACKGROUND: Becker's nevus (BN) is a unilateral, hairy, pigmented cutaneous hamartoma which frequently appears in adolescence. Several features of BN suggest that increased androgen sensitivity plays a role in its pathogenesis. The diagnosis of BN is usually made clinically. It is sometimes …

Clinical and Histopathological Characteristics of Nevus Depigmentosus
PURPOSE: Nevus depigmentosus (ND) is known to be a rare congenital, nonprogressive disorder characterized by hypopigmented lesion that remains stable over time. There have been only few studies of clinical and histopathological characteristics of ND, and the etiopathogenesis is not fully …

Zebrafish as a model of BRAFV600E melanoma subtypes and Nevus biology
… develop the first animal model for BRAFV600E nevus recurrence. In my first data chapter, I develop a unique animal model of nevus recurrence. In people it is not uncommon for a nevus to recur following removal, even when no pigmented nevus cells remain. The biology of how and why this happens …

Clinical and Histological Characteristics of Melanocytic Nevus in External Auditory Canals and Auricles
Nevi, which consist of nevus cells arising from external auditory canals (EACs) and auricles, are rare and their characteristics are not thoroughly understood. The purpose of this study was to analyze the clinicopathological characteristics of melanocytic nevus (MN) in EACs and auricles. Medical …

Histopathologic Features in Vitiligo
… skin. We also compared them to 30 cases with nevus depigmentosus skin. RESULTS: The general histologic features of vitiligo showed more frequent basal hypopigmentation and dermal inflammation than perilesional normal skin. Basal hypopigmentation compared with perilesional normal skin was also …

Malignant melanoma-Risk factors and the CDKN2A mutation in relation to phenotypes and other cancers.
… in non-mutation carriers. The overall total nevus count (median 12, IQR: 5-25) and rate of individuals affected by CAN (14%), were lower in these families than shown in previous, population-based, Swedish studies. No atypical mole syndrome (AMS) phenotype was seen. Paper IV: Family history …

Multi-spectral light interaction modeling and imaging of skin lesions
… for imaging and give information related to the nevus depth and structure. Using the selected wavelengths, multi-spectral trans-illumination images of the skin lesions are collected and analyzed. An adaptive wavelet transform based tree-structure classification method (ADWAT) is proposed to …

Laser treatment of hemangiomas using spectroscopic feedback : the "smart scalpel"
… approach to treatment of skin hemangiomas like nevus flammus (port wine stain or PWS). Current PWS phototherapy relies on selective absorption of optical radiation by the ectactic blood vessels in a PWS resulting in thermally mediated vessel necrosis. Although shown to be effective, heating of …
