The content of elastic tissue has been evaluated in 171 primary breast carcinomas. Of the tumors, 35% had no or very little elastic tissue in the malignant areas, 42% presented with medium elastosis, and 22% had gross elastosis. The occurrence of elastin has been related to different prognostic factors. An increasing amount of elastin was found with increasing amounts of estrogen receptor (p = ...

Melasma is a commonly acquired hypermelanosis that affects sun-exposed areas of the skin, with frequent facial involvement. Its histologic manifestations are evident in the epidermis, extracellular matrix, and dermis. In addition to epidermal pigmentation, pathologic findings of melasma include extracellular matrix abnormality, especially solar elastosis. The disrupted basement membrane has bee...

Elastosis Perforans Serpiginosa (EPS) is a rare skin disease characterised by hyperkeratotic papules, transepidermal elimination of abnormal elastic fibres, and focal dermal elastosis. The aetiology is unknown, but an association with underlying systemic disorders, including Down syndrome has been described. Treatment is often difficult. A 45-year old man with Down syndrome presented with symme...

R ecent data show that melasma lesions have, in addition to increased pigmentation, more elastosis and vascularization than perilesional skin. The stabilized formulation of Kligman preparation has shown significant improvements in the treatment of melasma. However, most of the treatments only target the pigmentation, and none of them has been demonstrated so far to prevent the frequent relapses...
