Neurofibromatosis belongs to the group of systemic hereditary diseases from the group of phakomatosis, characterized by developmental defects of ectodermal and mesodermal structures, mainly of the skin, nervous and bone systems, with an increased risk of developing malignant tumors. There are 7 types of the disease include a wide range of clinical manifestations even within the same family: a progressive course, the involvement of almost all organs and systems in the process, a high risk of complications, including many serious and fatal (cardiovascular) pulmonary insufficiency due to severe skeletal abnormalities, malignant degeneration by neurofibromas, etc.). An analysis of 5 clinical cases with neurofibromatosis is presented.

We presented a case of Andrews pustular bacterid in a 41-year-old differential diagnosis and disease treatment are discussed.

We present a case of disseminated superficial actinic porokeratosis and describe general dermoscopic features.

Aim: analysis of different dermatoscopic patterns of lichen planus and psoriasis. Material and methods. We observed 80 patients: 40 with psoriasis, 40 — with lichen planus. Dermatoscopic study was conducted using video-dermatoscope of expert class "MoleMaxHD" (Derma Medical Systems company, Austria), under magnification from хЗО to x80. Results. Comparing the dermotoscopic findings of psoriatic plaque and lichen planus, vascular features were found to be more significant in psoriasis and in lichen planus non-vascular features were more prominant. Conclusion. Dermoscopy can be successfully used in differential diagnosis of these dermatoses.
