Patients with a high total nevus count (TNC) merit a total-body examination, but a simple strategy to identify these high-risk individuals is essentially missing. The aim of this study was to investigate the correlation between the number of melanocytic nevi on both arms and the TNC, and to evaluate patient variables that may have an effect on this...

High-frequency ultrasound is non-invasive imaging method for examination of skin tumours. The aim of our study was to examine validity of 20-MHz ultrasound in preoperative determination of skin tumour thickness localized on head and neck region as a potentially useful tool for planning of the surgical intervention. Seventy-three different skin tumo...

Acute suppurative parotitis (ASP), with or wit-hout development of abscess, occurs mainly in the elderly, but in children except in the newborn peri-od, as a single attack occurs sporadically. We describe infant with prolongate infection of respiratory tract complicated with ASP and later development of abscess of parotid gland. After an-tibiotic t...

Twenty-megahertz ultrasound is a potentially useful noninvasive method for the preoperative determination of tumor dimensions and for defining tumor margins and shape.1 Using 20-MHz ultrasound equipment (Dermascan C; Cortex Technology, Hadsund, Denmark), we examined 35 different types of skin tumors (basal cell carcinoma [n = 12], nevus pigmentosus...

Light radiation is a part of the electromagnetic radiation, and it consists of the ultraviolet (UV) radiation, visible light, and infrared radiation. UV radiation energy is absorbed in the form of photons in biomolecules (chromophores) and induces various cellular reactions, out of which photochemical and photosensitizing are the most significant....

Objective: Chronic contact allergic dermatitis (CAD) and contact irritant dermatitis (CID) of palms and soles have similar clinical features. The pathohistological characteristics of chronic palmoplantar CAD and CID are also similar, as presented by hyperkeratosis, acanthosis, and a chronic inflammatory infiltrate in dermis. The aim of our study wa...
