Subjective and objective assessment of color match of universal tinted sunscreens in Fitzpatrick skin phototypes I-VI.

BACKGROUND: Tinted sunscreens not only shield against UV rays but also provide protection against visible light, as opposed to traditional sunscreens. Universal tinted sunscreens are marketed to complement all skin tones. OBJECTIVE: To assess color match and subject satisfaction for 7 universal tinted sunscreens across various price ranges in all Fitzpatrick skin phototypes (SPT). METHODS: Products A-G were applied at concentrations of 1 and 2 mg/cm2 on the dorsal arms of 30 subjects spanning SPT I-VI. Photography, colorimetry, and subject and investigator surveys were utilized to determine color match. RESULTS: Using colorimetry analysis at the recommended 2 mg/cm2 concentration, two of seven products were identified as suitable matches for SPT I-II, while six out of seven were determined to be a good match for SPT III-IV. However, only one product was found to be a good match for SPT V-VI at the recommended concentration according to colorimetry results. CONCLUSION: Universal tinted sunscreens do not provide an adequate color match for all skin phototypes, especially for individuals with very fair or very dark skin tones.

Case Series of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis With Nivolumab and Nivolumab/ Ipilimumab Combination Therapy in Metastatic Melanoma.

Nivolumab (anti PD-1 antibody) and ipilimumab (anti CTLA-4 antibody) are immune checkpoint inhibitors (ICI) that effectively stimulate the native T cell response and lead to an antitumor response. The medications have been approved for the treatment of metastatic melanoma. However, ICIs are associated with higher risk for cutaneous immune-related adverse events (irAEs). Although most of the adverse events present as maculopapular rash, some patients develop Stevens-Johnson Syndrome (SJS) or Toxic Epidermal Necrolysis which are dermatologic emergencies with high mortality. We report a fatal case of SJS associated with nivolumab and a non-fatal case of TEN with nivolumab/ipilimumab combination therapy in patients with metastatic melanoma. It is also not unusual to develop SJS or TEN after weeks or months on checkpoint inhibitor therapy. Given the high rate for mortality, dermatologists and other clinicians should closely follow any rash from these immunotherapies due to the risk for future development of SJS or TEN.

Surgical management of a local angioinvasive fungal soft tissue infection in the knee: a case report.

A 58-year-old male with an insignificant past medical history presented with chronic myelogenous leukemia in blast crisis. He began induction chemotherapy complicated by neutropenic fever. The patient then developed a nontender 1.5 cm violaceous firm indurated papule above the left patella with satellite lesions on his wrist and chest. A biopsy of the left patella showed obliterated blood vessels in the deep reticular dermis and numerous hyphae with septation and acute angle branching in the vessel wall consistent with angioinvasive aspergillosis. He was started on liposomal amphotericin and empiric voriconazole. Urgent local surgical excision of the primary lesion was recommended for source control. There is no clear recommendation on surgical intervention for angioinvasive aspergillosis, and further direction is needed. We present a case that illustrates surgical debridement for angioinvasive aspergillosis to be an effective method of source control along with systemic antifungal therapy.

Erythrasma.

THE COMPARISONA and B Axilla of a 65-year-old White man with erythrasma showing a well-demarcated erythematous plaque with fine scale (A). Wood-lamp examination of the area showed characteristic bright coral red fluorescence (B).C and D A well-demarcated, red-brown plaque with fine scale in the antecubital fossa of an obese Hispanic woman (C). Wood-lamp examination revealed bright coral red fluorescence (D).E Hypopigmented patches (with pruritus) in the groin of a Black man. He also had erythrasma between the toes.
