Epidermotropic carcinomas are neoplasms with an unusual but specific propensity for invading and intimately associating with the epidermis. A unique case of squamous cell carcinoma of the vagina with epidermotropic cutaneous metastases is described.
Acrokeratoelastoidosis is a very rare entity of unknown etiology, characterized by small, firm, yellowish, translucent papules which usually appear on the margins of the hands and feet between the junction of the dorsal and palmar/plantar skin. Histologically, the most characteristic features are hyperkeratosis, mild acanthosis, and, most strikingly, fragmentation of coarse elastic fibers within the reticular dermis. This eruption is variable in terms of its onset, may be sporadic or familial, is generally asymptomatic, and has a prolonged course.

This is a case of carcinoma of the gallbladder, which clinically, chemically, and radiographically simulated metastatic prostate cancer. Other causes of elevated serum and bone marrow acid phosphatase and axial skeletal osteoblastic metastases are reviewed.
Areas of medial alteration (Erdheim cystic medionecrosis) in an aortic root aneurysm surgically removed from a patient with Marfan syndrome were studied with an electron microscope. The single striking morphologic abnormality was the disorganized, haphazard architecture of the media in these areas. This lesion is interpreted as being an abortive reparative response to hemodynamic stress in a condition with a molecular defect in the structural proteins of connective tissue.
