BACKGROUND
Limited information exists on the demographics, tumor characteristics, and treatment in primary cutaneous mucinous carcinoma (PCMC).
OBJECTIVE
The authors sought to describe prognostic factors, incidence rates, and the subsequent primary malignancy (SPM) risk in patients with PCMC.
METHODS
Primary cutaneous mucinous carcinoma cases in the National Cancer Institute's Surveillance, Epidemiology, and End Results data (1972–2013) were analyzed to provide demographic, cancer-related, and treatment information and to calculate incidence and mortality. Patients were stratified by stage (local, regional, distant disease) for comparison. The risk of developing an SPM was calculated.
RESULTS
Four hundred eleven PCMC cases were identified. The age-adjusted incidence was 0.04 cases per 100,000-person years. Blacks were disproportionately affected by PCMC (0.048; 95% confidence interval, 0.034–0.065; p < .001). Approximately 67.4% of patients had local disease, 10.5% had regional disease, and 5.8% had distant disease. Primary cutaneous mucinous carcinoma–specific mortality was independent of sex, age, race, primary site, histologic tumor grade, tumor size, tumor stage, or treatment. The overall frequency of developing a second primary malignancy was not increased in patients with PCMC.
CONCLUSION
Although PCMC occurs with equally in both sexes, it may be more common in African Americans than previously recognized. Although eyelid PCMC may have a higher rate of distant metastasis, all patients need close follow-up.
Coronavirus Disease 2019 (COVID-19) represents a global health crisis in which personal protective equipment has become increasingly limited. Dermatologists are poised to use technology, such as teledermatology, to innovate existing workflows and optimize dermatologic care. The state of Ohio has emerged as a leader in the United States with its response to the COVID-19 crisis. In response to the COVID-19 crisis, we developed a simple algorithm and strict guidelines to prioritize telemedicine specifically for inpatient dermatology consults. This algorithm was quickly accepted by our hospital leadership and adopted by other inpatient consultative services. In this Viewpoint, we share our experience with early adoption of teledermatology in the inpatient consultative setting in light of the COVID-19 crisis. We also highlight the limitations, ethical considerations, and areas for future research with respect to the implementation of teledermatology.
ARTICLE HISTORY
Aggressive digital papillary adenocarcinoma is a rare malignancy with increasing incidence. Regional disease spread is not infrequent, but mortality is rare. Identification of patients best suited for additional diagnostic procedures or more extensive surgical resection remains challenging.
PLA patients should be initially treated non-operatively, barring indications for emergent surgery or inaccessibility for PD. Surgery can be reserved for failure of PD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
