The paper considers the application of an algorithm based on a morphological projector for determining structural differences comparing dermoscopic images. This will allow to identify changes that have occurred in skin lesions over time, more accurate diagnosis their malignancy. proposed makes it possible detect images even if there is significant difference brightness and color levels compared...

Background Sebaceous neoplasms of the skin (SN) are described in the Muir Torre variant of Lynch syndrome (LS). Guidelines recommend evaluating individuals diagnosed with sebaceous adenomas or sebaceous carcinomas for LS with immunohistochemistry (IHC) for mismatch repair (MMR) proteins and/or microsatellite instability analysis (MSI). The assumption has been that SNs with defective MMR are rel...

Cases of surgical treatment basal cell skin carcinoma the lower eyelid are rarely described in world literature. Perhaps this is due to search for new non-surgical methods or fact that localization poorly represented total incidence cancer. However, operative method, recommended as main line by both domestic and foreign clinical recommendations, still recognized most radical aesthetically accep...

The paper represents an overview of updated literature concerning common skin neoplasms. The clinical manifestation of the basal cell carcinoma varies significantly according to the patients age, tumor size, localization and duration of the neoplastic process, histological type of the tumor, including proliferative activity and stromal reactions.

The association of leukocytoclastic vasculitis and renal cell carcinoma has been rarely documented. We report a patient who presented with leukocytoclastic vasculitis involving the skin and was diagnosed later as renal cell carcinoma. After the nephron-sparing surgery, the vasculitic lesions disappeared. We also briefly review cases of vasculitis and renal neoplasms.

Primary non-Hodgkin lymphoma of the larynx is rare, accounting for less than 1% of all laryngeal neoplasms. Fewer than 100 cases have been reported in the literature and to our knowledge this may be the first reported case of laryngeal non Hodgkin lymphoma presented with hoarseness, aortic aneurysm, hepatitis B and skin rashes.

BACKGROUND Urticaria pigmentosa (UP) is characterized by dense aggregates of mast cells in the dermis. There is consistent evidence from the literature that mast cells may play a pathogenetic role in the development of neurofibromas and other tumors. OBJECTIVE To study the concomitant appearance of UP with neurofibromas and neurofibroma-like neoplasms. METHODS We analyzed 31,752 records of ...
