Resident Rounds part III: scleromyxedema: a rare disorder associated with a monoclonal gammopathy.

Scleromyxedema is a rare primary cutaneous mucinosis affecting middle-aged adults. It is characterized by dermal mucin deposition with increased collagen in the skin and internal organs. We report a case of a 72-year-old man with classic skin findings of scleromyxedema as well as a monoclonal gammopathy.

Achieving hemostasis in dermatology - Part 1: Preoperative, intraoperative, and postoperative management.

As dermatological procedures continue to become increasingly complex, improved methods and tools to achieve appropriate hemostasis become necessary. The methods for achieving adequate hemostasis are variable and depend greatly on the type of procedure performed and the unique characteristics of the individual patient. In Part 1 of this review, we discuss the preoperative, intraoperative, and postoperative management of patients undergoing dermatologic surgery.

Paradoxical darkening and removal of pink tattoo ink.

It is widely accepted that Q-switched lasers are the gold-standard treatment for the resolution of unwanted tattoo ink. Although much safer than other tattoo removal modalities, the treatment of tattoo ink with Q-switched devices may be associated with long-term adverse effects including undesired pigmentary alterations such as tattoo ink darkening. Darkening of tattoo ink is most often reported in cosmetic, flesh-toned, white, peach, and pink tattoos.

Cutaneous allergic reactions to tattoo ink.

Tattoo artists use many compounds to create tattoo pigment and several allergic reactions can occur as a result of these additives. The compositions of many inks have been identified; however, as new mixtures are created it becomes difficult to identify the specific ingredients in a particular ink. Allergic reactions to a particular pigment can manifest in several ways including allergic contact dermatitis and photoallergic dermatitis.
