Possible relationship between bilateral elastofibroma dorsi and hypermastia
(2017)
Elastofibroma dorsi (EFD) is a rare, benign, soft tissue tumor with an unclear pathogenesis, typically localized to the subscapular region. It occurs within the periscapular area between the ribs and dorsal chest wall ...
Posterior polar central choroidal dystrophy: A case report
(2017)
A 52-year-old male presented with a 25-year history of decreasing vision. Best corrected visual acuity was 0.3 in his right and 0.2 in his left eye. Fundoscopic examination showed bilateral symmetric atrophy of the retinal ...
Relay node selection and power allocation for distributed self-concatenated convolutional codes
