Indolent CD8+ primary cutaneous T-cell lymphoma involving the eyelid of an adolescent.

Primary cutaneous acral CD8+ T-cell lymphoma (PCACTL) is currently a provisional entity defined as a rare cutaneous proliferation of atypical CD8+ lymphocytes that preferentially involves acral sites and has a good prognosis. We present a case of primary cutaneous CD8+ T-cell lymphoma involving the eyelid of an adolescent male. The case shares features with PCACTL, including indolent clinical behavior and expression of CD68 in a Golgi-associated dot-like pattern; however, other features differ significantly from PCACTL as currently defined by the World Health Organization (WHO).

Hyfrecation and Interference With Implantable Cardiac Devices.

Background: Mohs micrographic surgery, excisional surgery, and electrodessication and curettage (ED&C) are common dermatologic procedures that often use electrodessication through hyfrecators to achieve hemostasis. According to in vitro studies, electrodessication is considered safe in patients with implanted cardiac devices. To the authors' knowledge, there are no in vivo data to support this claim.

Focal cutaneous squamous cell carcinoma following radium-223 extravasation.

Long-term sequelae due to extravasation of intravenous radioisotopes resulting in radiation injuries are rarely reported. As the use of radioactive isotopes for the treatment of osteoblastic metastases increases, information regarding the prevention, treatment, and long-term monitoring of suspected extravasation injury will become increasingly important. We present a patient with no previous history of skin cancer who developed an aggressive cutaneous squamous cell carcinoma at the site of prior radium-223 extravasation.
