Low-grade myxofibrosarcoma presenting at the site of prior high-grade disease.

Myxofibrosarcoma is one of the most common soft tissue sarcomas occurring in older adults. It can arise de novo or can be radiation induced, and the term myxofibrosarcoma was originally devised to encompass a spectrum of myxoid tumors with characteristics similar to malignant fibrous histiocytoma (MFH). Confusion exists, however, regarding the distinction between microscopic grade and characteristics of myxofibrosarcoma and MFH.

Palmoplantar keratoderma as the initial sign in a peripheral T-cell lymphoma.

A 27-year-old male with an acquired severe, diffuse palmoplantar keratoderma as the initial sign of peripheral T-cell lymphoma is reported.

Pulmonary cutaneous metastasis: a case report and review of common cutaneous metastases.

The literature on cutaneous metastatic disease can be difficult to interpret because of inconsistent study design and analysis among authors. Furthermore, one should be careful when reviewing the statistics in the literature, as reported patient populations tend to vary and are not representative of the whole population. However, certain trends are notable and should be reported.

Primary cutaneous nodular amyloidosis: case report and review of the literature.

Primary cutaneous nodular amyloidosis (PCNA) is a rare form of primary cutaneous amyloidosis. It presents as waxy yellow-red nodules that are located preferentially on the lower extremities, face, scalp, and genitals. Recognition of this condition is of particular importance, as primary systemic amyloidosis can have a similar cutaneous presentation.

Current and future trends in home laser devices.

Laser and intense pulse light procedures, once limited to physician offices and operating rooms, have become increasingly available at a variety of nonmedical sites such as spas. State regulations as to whom can perform these treatments varies greatly across the United States and, thus, in some states, the operators of these devices do not have any significant additional medical or laser knowledge more so than the patients who receive treatment. Although serious complications of laser treatments occur, they are rare when the procedure is performed correctly.

Localized heat induced urticaria: report of a case.

Localized heat induced urticaria is a rare clinical entity. Other physical urticarial subtypes include cholinergic, solar, cold, aquagenic, vibratory, and dermatographic. It is characterized by a well-demarcated urticarial lesion provoked by heat in direct contact with the skin.
