RESUMO
Epithelioma cuniculatum (EC) is a subtype of verrucous carcinoma (VC) that affects the feet. Treatment involves complete tumor removal by wide local excision (WLE) or Mohs micrographic surgery (MMS). Extensive local destruction may require amputation. We sought to compare reported treatment methods for EC and determine their efficacy by assessing for tumor recurrence and treatment-associated complications. A systematic review of the literature spanning multiple databases was performed. To date, surgical excision is recommended as the standard of care for treatment of EC, with amputation considered in more advanced cases. Mohs micrographic surgery appears to be a promising treatment modality for EC and may have lower recurrence rates than WLE but requires further investigation.

BACKGROUND: Plasma cell vulvitis (PCV) is an inflammatory vulvar dermatosis that is not well characterized. Diagnosis is often delayed, and the condition can be refractory to treatment. To date, there are no systematic reviews on this topic. OBJECTIVE: This study aimed to provide a systematic review of PCV, including epidemiologic, clinical, and histopathologic findings, as well as associated comorbidities and treatment options. METHODS: A primary literature search was conducted using the PubMed, Ovid Medline, Cochrane, and CINAHL databases. RESULTS: Fifty-three publications with 196 patients (mean age: 55.3 ± 14.5 years) were included. The majority of studies were case reports and case series. Common symptoms included burning/stinging (52%), dyspareunia (44%), and pruritus (41%). Common findings included erythema (84%), glistening/shiny appearance (29%), well-demarcated lesions (25%), and erosions (22%). Common anatomic sites were the labia minora (45%), introitus (31%), and periurethral (19%). Fifty-three percent of patients had a solitary lesion. Common histologic findings were a predominant plasma cell infiltrate (88%), presence of other inflammatory cells (55%), hemosiderin/siderophages (46%), and epidermal atrophy (43%). Topical corticosteroids (64%) and tacrolimus ointment (13%) were the most frequent treatment modalities. In most reports, previous treatments were tried, and there was a diagnostic delay. CONCLUSION: PCV is likely underrecognized and should be considered in patients with erythema of the mucous and modified mucous membranes, symptoms of burning or stinging, and a predominant plasma cell infiltrate on histopathology. First-line therapy should begin with high-potency topical corticosteroids, with the most evidence for clobetasol 0.05% or tacrolimus 0.1% ointment. Prospective studies are needed to further characterize this condition and to develop treatment guidelines.
RESUMO
BACKGROUND: Immunotherapy using programmed cell death 1 protein (PD-1) or programmed death-ligand 1 (PD-L1) inhibitors has been increasingly reported in a variety of nonmelanoma skin cancers (NMSCs). OBJECTIVE: To analyze the evidence of PD-1 and PD-L1 inhibitors in the treatment of NMSC. METHODS: A primary literature search was conducted with the PubMed, Cochrane Library, EMBASE, Web of Science, and CINAHL databases through October 28, 2018, to include studies on the use of PD-1 or PD-L1 inhibitors in patients for NMSC. Two reviewers independently performed study selection, data extraction, and critical appraisal. RESULTS: This systematic review included 51 articles. The most robust evidence was in the treatment of Merkel cell carcinoma and cutaneous squamous cell carcinomas, as supported by phase 1 and 2 clinical trials. Treatment of basal cell carcinoma, cutaneous sarcoma, sebaceous carcinoma, and malignant peripheral nerve sheath tumor also showed benefit with PD-1/PD-L1 inhibitors, but data are limited. There does not appear to be efficacy for PD-1/PD-L1 inhibitors in cutaneous lymphomas. LIMITATIONS: More investigation is needed to determine the efficacy, tumor responsiveness, and the safety profile of PD-1 and PD-L1 inhibitors in NMSC. CONCLUSION: PD-1 and PD-L1 inhibitors exhibit treatment efficacy in a variety of NMSCs.
