Painful Papules on the Arms

A Systematic Review of Diagnoses With Rosettes Under Dermoscopy

“…A subsequent report on a child who had two fleshy papules with rosettes raised concerns about SCC, which led to the decision to perform skin biopsies. The biopsies ultimately confirmed the presence of molluscum contangiosum instead [ 7 ]. Increased awareness of the presence of rosettes in infectious conditions, such as molluscum, has the potential to improve diagnostic accuracy and reduce the number of biopsies performed in pediatric patients.…”

“…Most articles were case reports featuring single entities, with limited dermoscopic images and lacked descriptive details necessary for further characterization of rosettes. In our own observations, rosettes are commonly diffuse in actinic keratoses, but are few and randomly arranged in entities such as scars and molluscum contagiosum [ 7 ]. Additionally, knowledge of hair follicle size and distribution in different body sites could provide further insight into the distribution and appearance of rosettes in different entities.…”

Megalopyge opercularis Caterpillar Stings Reported to Texas Poison Centers

“…3 Treatment may involve applying tape to the site and pulling it off to remove the spines (stripping), ice packs, antihistamines, and baking soda. 2,4,5 The published literature on M opercularis caterpillar stings mostly consists of case reports [6][7][8][9][10][11][12] or a relatively small number of cases. 2,4,13 The objective of this investigation was to describe M opercularis caterpillar stings reported to poison centers in Texas, a state where M opercularis caterpillars have been noted to be particularly abundant.…”
