Cutaneous Mycobacterium avium-intracellulare infection masquerading as sarcoidosis.

Mycobacterium avium-intracellulare (MAC) infection may have different skin manifestations, including cutaneous granulomas. Granulomatous skin reactions have distinct morphologic and histopathologic appearances. We present the case of an adolescent male with cutaneous MAC, misdiagnosed as sarcoidosis after initial biopsy results, demonstrated preservation of reticulin fibers and absence of organisms within granulomas.

A Non-Surgical and Cost-Effective Treatment Approach Employing Topical Imiquimod, 5-Fluorouracil, and Tretinoin for Primary Non-Melanoma Skin Cancers.

Background: Minimally invasive alternative approaches to treat non-melanoma skin cancers remain limited and unproven.

Objective: We aim to assess the efficacy of varying combinations of anti-tumor agents—imiquimod 5% cream, 5-fluorouracil 2% solution, and tretinoin 0.1% cream—with brief cryotherapy in treating non-melanoma skin cancers.

Re-pigmentation of Hypopigmentation: Fractional Lasers vs Laser-Assisted Delivery of Bimatoprost vs Epidermal Melanocyte Harvesting System.

Background: Hypopigmentation is a common cutaneous manifestation that frequently poses a therapeutic challenge for dermatologists. Current treatments have varying efficacies and rarely provide patients with long-term results. However, new treatments are emerging, and head-to-head studies comparing these treatments are warranted.

Combined Systemic and Intratumoral Administration of Human Papillomavirus Vaccine to Treat Multiple Cutaneous Basaloid Squamous Cell Carcinomas.

Importance: Squamous cell carcinoma (SCC) is the second most common form of skin cancer, and its incidence is increasing. When surgical management is not an option, finding a safe and efficacious treatment is a challenge. Mounting evidence suggests that the human papillomavirus (HPV) is involved in the pathogenesis of some SCCs.

Widespread Skin Necrosis Secondary to Gemcitabine Therapy.

Gemcitabine, a pyrimidine nucleoside analogue, is an oncologic agent used in the treatment of cutaneous T-cell lymphoma (CTCL). Common dermatologic reactions associated with gemcitabine include alopecia, mild skin rash, and mucositis but skin necrosis is exceptional. Herein we present an unusual case of widespread skin necrosis mimicking toxic epidermal necrolysis in a 45-year-old woman receiving gemcitabine therapy for stage IIIA cutaneous T-cell lymphoma.
