It is usually nonpigmented even if there is a pigmented variant that corresponds to 17% of cases and it is usually underdiagnosed, since it is mistakenly confused with ...
متن کاملPigmented Eccrine Poroma in abdominal region, a rare presentation
The eccrine poroma or Hidracanthoma Simplex is a rare benign adnexal tumor of ephitelial cells, with an incidence of 0.001 to 0.008%1. In two-thirds of the patients it appears on the soles and lateral borders of the feet.

متن کاملAmyloid deposition in Alzheimer's disease.
Alzheimer's disease (AD), a progressive neurodegenerative disorder, accounts for approximately 60 percent of all victims of dementia and affects greater than 10 percent of the population over 65 years old. Although the cause is unknown, there is evidence that beta-amyloid plays an important role in its pathogenesis. The deposition of this type of amyloid in the brain and its implications in AD ...
متن کاملPigmented eccrine poroma of the palm clinically mimicking a seborrheic keratosis
CEA: Carcinoembryonic antigens EP: Eccrine poroma E ccrine poroma (EP) is a benign neoplasm of the eccrine terminal duct, composed of epithelial cells that show tubular differentiation. EP often presents as a reddish nodule with a predilection for the distal extremities. This report describes a lesion with the clinical and dermoscopic findings of a seborrheic keratosis. However, histopathologic...
