Immunomodulatory drugs that leverages host immune mechanisms to destroy tumor cells have been met with great promise in the treatment of cancer. Immunotherapy, targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and the programmed cell death 1 (PD-1) receptor and its ligand (PD-L1) have shown tremendous improvements in the survival of patients with advanced solid tumors. However, the development of dermatologic toxicity (DT) is a consequence to immunotherapy.

Disseminated histoplasmosis most commonly occurs in immunosuppressed individuals and involves the skin in approximately 6% of patients. Cutaneous histoplasmosis with an intraepithelial-predominant distribution has not been described. A 47-year-old man was admitted to our institution with fever and vancomycin-resistant enterococcal bacteremia.

Monoclonal antibodies against the immune checkpoint programmed cell death receptor 1 (PD-1) improve the hosts' antitumor immune response and have showed tremendous promise in the treatment of advanced solid tumors and hematologic malignancies. Reports of serious autoimmune dermatologic toxicities from immune checkpoint blockade therapy, however, are emerging. We report our experience with five patients who presented with pruritic vesicles and blisters on the skin while treated with anti-PD-1 antibody immunotherapy with either nivolumab or pembrolizumab.

Importance: Extramammary Paget disease (EMPD) is an uncommon tumor that presents in apocrine-rich skin as an irregular, pruritic plaque. Histopathologically, EMPD consists of an intraepidermal proliferation of atypical epithelioid cells. Rarely, the tumor cells contain intracytoplasmic melanin pigment, and the lesion clinically and histopathologically can mimic a melanocytic proliferation.

Topical antibiotics are used for various purposes in dermatology. Some of the most common uses include treatment of acne, treatment and prevention of wound infection(s), impetigo or impetiginized dermatitis, and staphylococcal nasal carrier state. It is important for the dermatologist to be familiar with the spectrum of activity, the mechanism of action, and the variables that may interfere with the antibiotic of choice.

Article Synopsis
  • Malignant acanthosis nigricans (MAN) is a rare skin condition linked to cancer, causing thickened, darkened skin and wart-like growths in the mouth, which can make eating and drinking difficult.* -
  • There is no targeted treatment for MAN, but addressing the underlying cancer may improve symptoms, with varying degrees of success.* -
  • In a reported case, a patient with MAN related to gastric adenocarcinoma was treated with oral retinoids, leading to significant improvements in skin symptoms and overall patient functionality.*

Sinus histiocytosis with massive lymphadenopathy, or Rosai-Dorfman disease, is a benign idiopathic histiocytic proliferative disorder that commonly involves the lymph nodes but secondarily may involve the skin. However, purely cutaneous disease without lymphadenopathy or internal organ involvement rarely may occur. We present case reports of three patients who presented with asymptomatic nonspecific enlarging skin nodules without evidence of lymphadenopathy or internal disease.
