Lichen planus of the esophagus: what dermatologists need to know.

Background: Esophageal lichen planus (ELP) is a rare manifestation of mucocutaneous lichen planus (LP).

Objectives: We aimed to report our experience and review all cases of ELP reported in the English-language literature.

Methods: We report our experience with 4 cases and reviewed PubMed for reports of ELP.

Bullous pyoderma gangrenosum as the presenting sign of fatal acute myelogenous leukemia.

Bullous pyoderma gangrenosum begins as a bulla, nodule or nonulcerated erythematous plaque that blisters or ulcerates to form a superficial ulcer surrounded by a hemorrhagic, bullous border, which is surrounded by a blue-gray halo. Bullous pyoderma gangrenosum is most commonly associated with hematologic malignancies, specifically, acute myelogenous leukemia (AML). We report a patient whose initial presentation with bullous pyoderma gangrenosum prompted the appropriate diagnostic evaluation and confirmation of AML, which was ultimately fatal.

Cutis verticis gyrata in a patient with Noonan syndrome.

We report cutis verticis gyrata in a patient with Noonan syndrome. While cutis vertices gyrata has been shown to have a strong association with chromosomal abnormalities, especially Turner syndrome, this infant represents only the second reported instance of cutis verticis gyrata occurring in a patient with Noonan syndrome.

Pyomyositis.

Four patients were admitted to Columbia Presbyterian Medical Center for evaluation of lower extremity pain and swelling. Three patients were initially misdiagnosed with cellulitis and one patient underwent evaluation for dermatomyositis. After consultation by the dermatologist, a correct diagnosis of pyomyositis was made clinically and confirmed by imaging, surgery, or an interventional procedure.

Mycobacterium abscessus cellulitis and multifocal abscesses of the breasts in a transsexual from illicit intramammary injections of silicone.

We report the case of a 29-year-old transsexual who developed Mycobacterium abscessus infection after receiving intramammary liquid silicone injections in the nonphysician office setting. Our patient represents 1 of 14 confirmed and 11 suspected cases in New York City of M abscessus infection after illicit cosmetic procedures. As injectable cosmetic procedures are becoming increasingly popular, dermatologists should be aware of both the common and unusual complications.
