CIC::DUX4 fusion sarcoma represents a rare and aggressive subtype of undifferentiated small round blue cell tumors. We report on a 23-year-old African male who developed a rapidly enlarging inferolateral left buttock nodule with ulceration. After debulking excision of the lesion, histologic sections demonstrated sheets and lobules of atypical round blue cells with significant cytologic atypia.

Skin cancer is the most common malignancy affecting solid organ transplant recipients (SOTR), and SOTR experience increased skin cancer-associated morbidity and mortality. There are no formal multidisciplinary guidelines for skin cancer screening after transplant, and current practices are widely variable. We conducted three rounds of Delphi method surveys with a panel of 84 U.

Background: Because most of the US population will consist of nonwhite individuals by the year 2043, it is essential that both physicians and patients are educated about skin cancer in nonwhite persons.

Objective: To update the epidemiology, investigate specific risk factors, and facilitate earlier diagnosis and intervention of keratinocyte carcinoma in nonwhite individuals.

Methods: Institutional review board-approved retrospective chart review of all nonwhite patients who had received a biopsy-proven diagnosis of skin cancer at Drexel Dermatology during June 2008-June 2015.

Importance: The risk for skin cancer has been well characterized in white organ transplant recipients (OTRs); however, most patients on the waiting list for organ transplant in the United States are nonwhite. Little is known about cutaneous disease and skin cancer risk in this OTR population.

Objective: To compare the incidence of cutaneous disease between white and nonwhite OTRs.

Importance: Organ transplant recipients have a higher incidence of skin cancer. This risk is magnified over time and with continued exposure to immunosuppression. Skin cancer in nonwhite patients is associated with greater morbidity and mortality owing to diagnosis at a more advanced stage, which suggests that nonwhite organ transplant recipients are at even higher risk.

Importance: Immunosuppressed patients with solid organ transplants have an increased risk for nonmelanoma skin cancer. Vismodegib has been reported to be effective for select locally advanced or metastatic basal cell carcinomas. However, there is no data documenting the use and safety of vismodegib in immunosuppressed organ transplant patients.

Objective: To ascertain and clarify the effectiveness and advantages of the geometric staged excision technique for the removal of lentigo maligna (LM) and lentigo maligna melanoma (LMM).

Design: This was a retrospective review of a patient database composed of 293 cases of LM and LMM.

Setting: The Laser and Dermatologic Surgery Center in St Louis, Missouri, an academic-affiliated, private dermatologic surgery center.

Cutaneous and systemic plasmacytosis (C/SP), human herpes virus-8 (HHV8), negative multicentric plasmacytic Castleman disease (MPCD), and idiopathic plasmacytic lymphadenopathy are polyclonal plasma cell proliferations of unknown etiology that predominantly affect Asian individuals. Herein, we present our experience with a Vietnamese man with typical C/SP limited to the skin but, after 10 years, may have developed perirenal involvement, and with a white man with human immunodeficiency virus and HHV8 negative MPCD with involvement of skin, lymph nodes, and kidneys at presentation, and who later succumbed to gastric carcinoma. Based on a review of the literature, we suggest that C/SP, cutaneous MPCD, and idiopathic plasmacytic lymphadenopathy with skin involvement are part of a continuum rather than distinct entities and, as such, may be regarded as variants of HHV8-negative MPCD.

Background: Cutaneous sutures should provide an aesthetically pleasing result. After placing subcutaneous sutures, enough absorbable suture often remains for the superficial closure. Mohs surgeons often use a nonabsorbable suture to close the superficial layer to obtain cosmetically elegant results, but using this additional suture is less cost effective than using the remaining absorbable suture.

Maffucci syndrome is a rare, sporadic disease characterized by the development of multiple enchondromas and subcutaneous hemangiomas. Patients with Maffucci syndrome have a 23-37% risk of malignancy, with chondrosarcomas being the most common. Although the development of a chondrosarcoma in a patient with Maffucci syndrome may be expected, intracranial chondrosarcomas are rare.

Background: Retinoids are widely used in dermatology and may play a role in wound healing. The exact role of retinoids in wounds is confusing and controversial, however. Systemic retinoids are presumed to be detrimental to wound healing; however, this standard is based on isolated reports.

Erythema multiforme is an acute, hypersensitivity reaction of the skin often secondary to medications. Lamotrigine is a relatively new anticonvulsant medication approved for seizure and psychiatric disorders. Although the overall incidence of cutaneous reactions to lamotrigine is high, the incidence of serious eruptions such as erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis is low.
