A case of localized calcinosis cutis of the hands and fingers is described in an oil field worker with normal serum calcium and phosphorus levels. The proposed mechanism consists of percutaneous penetration and subsequent deposition of calcium from the daily exposure to industrial drilling fluids containing calcium salts.
A technique using serial split-thickness tangential excisions and polyurethane membrane dressings for removal of decorative tattoos is described.
Lennert's lymphoma is a fairly distinct clinicopathologic entity that may rarely involve the skin. Patients tend to be elderly women with prominent cervical adenopathy; they often have a rapidly fatal disease course. We describe here an 85-year-old woman with lymphadenopathy and erythematous cutaneous nodules who had malignant lymphohistiocytic infiltrates in both her skin and lymph nodes, with a high concentration of epithelioid histiocytes in the latter.
