RESUMEN
Although graft-versus-host disease (GVHD) is a common immunologic reaction after an allogeneic hematopoietic stem cell transplant (HSCT), progression into sclerodermatous GVHD is a rare sequela. It can present locally or generalized with various cutaneous and mucocutaneous manifestations, resulting in loss of skin elasticity and reduced functional capabilities. One of the most debilitating consequences of sclerodermatous GVHD is its effect on a range of motion due to fibrosis of the skin and subcutaneous fat. We present the case of a 54-year-old male with a medical history of acute myeloid leukemia and an allogeneic stem cell transplant who was diagnosed with sclerodermatous GVHD. We review the characteristic clinical and histopathological findings of sclerodermatous GVHD, as well as its treatment. Early recognition and intervention are crucial to prevent complications, such as joint contractures.
RESUMEN
Virtually any antibiotic can be used in dermatology given the broad range of conditions treated. With the widespread use of antibiotics and the rapid emergence of resistant organisms, it is important to understand how dermatologists can combat this issue.

We present a case of erythema multiforme (EM) associated with a third (booster) dose of COVID-19 vaccination in a patient who had no cutaneous reactions to previous doses. To our knowledge, this is the first documented case of vaccine-associated EM occurring after a third/booster vaccination. Furthermore, our case emphasizes the need to remain vigilant for vaccine-associated EM in any patient recently vaccinated, regardless of whether previous vaccinations were administered without cutaneous reactions.
RESUMEN
A 41-year-old woman presented for evaluation of a pruritic eruption with an abrupt onset, starting on her flanks and then spreading to her arms and legs. She had 2 weeks of fever, chills, malaise, migratory joint pain, nausea, and mental confusion. An antistreptolysin O titer was positive. Upon hospital admission, bilateral lower-extremity chorea movements were observed, and her C-reactive protein level was elevated (3.7 mg/dL). Biopsy results supported erythema marginatum. Based on these clinical and laboratory findings, the diagnosis of acute rheumatic fever was established.
