A Case Presentation of Three Polypoid Melanomas With Divergent Features.

Polypoid melanoma, a subtype of nodular melanoma, is classified as the most aggressive and deadly form of cutaneous melanoma. Its rapid vertical growth phase and a wide array of divergent features make clinical diagnosis extremely difficult. This report includes three cases of polypoid melanoma that were all originally thought to be other benign lesions or non-melanoma cancer.

The relationship between neighborhood typologies and self-rated health in Maryland: A latent class analysis.

Despite widespread evidence that neighborhood conditions impact health, few studies apply theory to clarify the physical and social factors in communities that drive health outcomes. Latent class analysis (LCA) addresses such gaps by identifying distinct neighborhood typologies and the joint influence that neighborhood-level factors play in health promotion. In the current study, we conducted a theory-driven investigation to describe Maryland neighborhood typologies and examined differences in area-level self-rated poor mental and physical health across typologies.
