While substantial dermoscopic analysis of melanocytic lesions has been performed, dermoscopic characterization of cutaneous lymphoid proliferations has been limited. Cutaneous lymphoma, particularly early mycosis fungoides (MF) and its variants, is often challenging to clinically and pathologically distinguish from inflammatory processes of the skin. This study aimed to survey the dermoscopic findings of cutaneous lymphomas and to discern whether any patterns might potentially serve as specific signatures.
Fifteen patients with an established diagnosis of cutaneous lymphoma were prospectively recruited and seen in the university multidisciplinary cutaneous lymphoma program with MF, an MF- variant, CD30-positive lymphoproliferative disorder, or cutaneous B-cell lymphomas and were included in our study. Dermoscopic findings, histologic features, clinical characteristics, and demographic data were analyzed.
Patch stage MF was characterized by interconnected white structureless patches encircling small fine linear vessels, yielding an overall trabeculated to fenestrated pattern under dermoscopy. Corresponding histopathologic findings for these patterns included epidermotropism, atypical pleomorphic cells, and lichenoid infiltrates. Folliculotropic mycosis fungoides (FMF) was characterized by folliculocentric erosions surrounded by dotted and fine linear vessels, loss of terminal follicles, comedo-like openings, and interconnected regular-appearing structureless patches. Corresponding histopathologic findings in these FMF cases were typical of FMF. Notably, these changes were not appreciated in lymphomatoid papulosis. Primary cutaneous follicle center B cell lymphoma showed crystalline structures and vascular pseudopods.
Cutaneous lymphomas appear to demonstrate characteristic dermoscopic patterns, reflective of the specific lymphoma type and its corresponding histopathology, which have not been seen in inflammatory skin conditions, such as psoriasis and eczematous dermatitis.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 January 2018.
All research outputs
#18,428,077
of 27,788,586 outputs
Outputs from International Journal of Dermatology
#2,433
of 3,875 outputs
Outputs of similar age
#280,792
of 459,150 outputs
Outputs of similar age from International Journal of Dermatology
#26
of 59 outputs
Altmetric has tracked 27,788,586 research outputs across all sources so far. This one is in the 33rd percentile – i.e., 33% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,875 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.3. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 459,150 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 59 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
