Seborrheic Keratoses of Florid Eruption
We report the case of a 79-year-old Caucasian man, who developed numerous pruritic seborrheic keratoses on his chest and back within one year. An underlying malignant disease was suspected. Upper and lower endoscopies were performed and the patient was diagnosed with adenocarcinoma of the ascending colon. We discuss the clinical significance of his cutaneous symptoms/signs, and review the medic...
متن کاملGenetic alterations in seborrheic keratoses
Seborrheic keratoses are common benign epidermal lesions that are associated with increased age and sun-exposure. Those lesions despite harboring multiple somatic alterations in contrast to malignant tumors appear to be genetically stable. In order to investigate and characterize the presence of recurrent mutations, we performed exome sequencing on DNA from one seborrheic keratosis lesion and c...
متن کاملOncogenic PIK3CA mutations occur in epidermal nevi and seborrheic keratoses with a characteristic mutation pattern.
Activating mutations of the p110 alpha subunit of PI3K (PIK3CA) oncogene have been identified in a broad spectrum of malignant tumors. However, their role in benign or preneoplastic conditions is unknown. Activating FGF receptor 3 (FGFR3) mutations are common in benign skin lesions, either as embryonic mutations in epidermal nevi (EN) or as somatic mutations in seborrheic keratoses (SK). FGFR3 ...
متن کاملEruptive inflamed seborrheic keratoses in the setting of endometrial adenocarcinoma☆
Eruptive seborrheic keratoses have been reported as a rare paraneoplastic dermatosis in the setting of internal malignancy, particularly that of the digestive tract. This case illustrates a patient with a family history of gastric cancer who presented with an acute eruption of inflamed pruritic seborrheic keratoses with annular and gyrate erythema, and was found to have endometrial adenocarcino...
متن کاملA segmental neurofibromatosis case with eruptive seborrheic keratoses.
Segmental neurofibromatosis (SNF) is a rare variant of neurofibromatosis (NF) type 1 characterized by a restricted distribution of cafe-au-lait macules, and/or neurofibromas, and rarely freckling to a single dermatomal segment. Patients with NF type 1 have an associated increased risk for benign or malignant tumours. The prevalence of typical NF type 1 complications including malignancies in SN...
