Clinical, dermoscopic and histopathologic findings of retiform hemangioendothelioma
Retiform hemangioendothelioma (RH) is an uncommon vascular neoplasm of borderline malignancy that clinically develops as a solitary, gradually enlarging exophytic mass, nodule or plaque, most often on the lower limbs, upper limbs and trunk. Clinical recognition of RH is troublesome because of its non-specific appearance, with differential diagnosis comprising a variety of benign and malignant t...
متن کامل[Complete regression of melanocytic nevi: correlation between clinical, dermoscopic, and histopathologic findings in 13 patients].
BACKGROUND The complete regression of melanocytic tumors, confirmed by histology, has rarely been reported in the literature. It is very difficult to determine the malignant or benign nature of a regressed tumor, and on occasions, the only indication of malignancy is the subsequent development of metastasis. MATERIAL AND METHODS We performed a descriptive study of melanocytic nevi that had un...

Actinic keratoses (AKs) are common skin lesions heralding an increased risk of developing squamous cell carcinoma (SCC) and other skin malignancies, arising principally due to excessive ultraviolet (UV) exposure. They are predominantly found in fair-skinned individuals, and increasingly, are a problem of the immunosuppressed. AKs may regress spontaneously, remain stable or transform to invasive...
متن کاملEpithelial Stem Cells of the Skin Contribute to the Histopathologic Umbrella-like Appearance in Actinic Keratosis
Although the histopathologic umbrella-like appearance of the epidermis in actinic keratosis (AK) is well known, its histopathogenesis has remained unknown. The author suggests that the penetration depth of ultraviolet B (UVB) radiation can account for such a histopathologic feature by affecting specific epidermal stem cell pools, as the stem cells in the epidermis and the bulge stem cells and s...
