BACKGROUND We previously reported a significant association between higher UV radiation exposure before diagnosis and greater survival with melanoma in a population-based study in Connecticut. We sought to evaluate the hypothesis that sun exposure before diagnosis was associated with greater survival in a larger, international population-based study with more detailed exposure information. ME...
BACKGROUND Cutaneous aging is due to intrinsic and extrinsic factors. While the pathologic hallmark of extrinsic aging (photoaging) is solar elastosis, intrinsic aging lacks any specific feature. Only a progressive thinning and loss of the dermal elastic network occasionally associated with focal thickening of the collagen bundles may be observed. In contrast to the different clinical patterns ...
BACKGROUND The occurrence of lichenoid keratosis (LK) on the face is not well characterized, and the histopathologic distinction between LK and lupus erythematosus (LE) occurring on the face is often indeterminate. The authors aimed to describe differences between LE and LK occurring on the face by hematoxylin and eosin alone. METHODS Cases of LK and LE were obtained using computer-driven que...
Transepidermal elimination (TE) is a mechanism whereby foreign or altered constituents can be removed from the dermis. This process involves unique morphologic alterations of the epidermis, which forms a channel and thereby facilitates extrusion of the desired dermal components. The phenomenon of TE may occur as a primary process characterizing disorders, such as elastosis perforans serpiginosa...
INTRODUCTION Idiopathic pulmonary haemosiderosis characterized by repeated episodes of intra-alveolar haemorrhage is rare in adults and has a relatively benign course compared to cases seen in children. CASE PRESENTATION The case presented here is of an adult man with idiopathic pulmonary haemosiderosis with mineralizing pulmonary elastosis. CONCLUSION Pathologists are generally not familia...
Skin rashes, proteinuria, systemic lupus erythematosus, polymyositis and myasthenia gravis have all been recorded as complications of penicillamine therapy in patients with rheumatoid arthritis. A patient who had developed all 5 is now described. The skin lesion resembled elastosis perforans serpiginosa, which has been reported as a rare side effect in patients with Wilson's disease but not in ...
