“…In these studies, the occurrence of angiogenesis in basal cell carcinoma was evaluated with videocapillaroscopy. The advantage of videocapillaroscopy is that it could detect the tumoral vascular structures that could not be detected by dermatoscopy [ 19 , 20 ]. In our study, magnification levels that could not be reached with videodermatoscopy were achieved with the image clarity offered by lesional capillaroscopy.…”

Introduction: Dermatoscopy is a frequently used non-invasive diagnostic procedure. Objectives: Considering that mycosis fungoides (MF) mimics parapsoriasis clinically in early stages, we aim to determine the dermatoscopic criteria and the histopathological correlations in patients with MF and small plaque parapsoriasis (SPP). Methods: This prospective study involved 28 patients with clinical and histopathological diagnoses of MF and 31 patients with SPP. Videodermoscopy and USB capillaroscope were used to evaluate the patients vessels at ×200 magnification. Vascularity was evaluated through microvascular density (MVD) scoring involving CD34 antibody staining. Results: Fifty-nine patients were included in this study. The scores corresponding to the presence of short linear vessels, linear-curved vessels, branching linear vessels, and non- structured orange-colored areas were significantly higher in the MF patients than in the SPP patients (P < 0.05). The highest MVD (P = 0.01) scores were also higher in the MF patients than in the SPP patients. Conclusions: The SPP and early-stage MF patients differed in their MVD scores, and the findings correlated with the dermatoscopy and lesional capillaroscopy findings. Differentiating features between SPP and MF were thus identified.

Objective: Dermatoscopy is a frequently used non-invasive diagnostic procedure. Considering that mycosis fungoides (MF) mimics parapsoriasis clinically in it's early stages, we aim to determine the dermatoscopic criteria and the histopathological correlations in patients with MF and small plaque parapsoriasis (SPP). Materials and Methods: This prospective study involved 28 patients with clinical and histopathological diagnoses of MF and 31 patients with SPP. Videodermoscopy and USB capillaroscope were used to evaluate the patients’ vessels at ×200 magnification. Vascularity was evaluated through microvascular density (MVD) scoring involving CD34 antibody staining. Results: Fifty-nine patients were included in this study. The scores corresponding to the presence of short linear vessels, linear-curved vessels, branching linear vessels, and non-structured orange-colored areas were significantly higher in the MF patients than in the SPP patients (p<0.05). The highest MVD (p=0.01) scores were also higher in the MF patients than in the SPP patients. Conclusion:The SPP and early-stage MF patients differed in their MVD scores (p=0.01), and the findings correlated with the dermatoscopy and lesional capillaroscopy findings. Differentiating features between SPP and MF were thus identifed.

“…Moreover, the application of additional imaging modalities, such as reflectance confocal microscopy (RCM), further characterizes these diseases to aid in their early detection. [11][12][13] Previous publications have illustrated clinical features of small-sized BCCs, typically 5 mm in diameter or smaller. There is a paucity of literature demonstrating dermoscopic and RCM features of BCCs measuring 2 mm or less, (which we refer to as micro-BCCs) that are also pigmented.…”

BackgroundBasal cell carcinoma (BCC) is the most common skin cancer, accounting for approximately 80% of nonmelanoma skin cancer diagnoses each year. Among other factors, the staging of BCC is influenced by its measured diameter. Stage 1 BCC is defined as a lesion measuring 2 cm across or less. Of note, there have been increasing publications reporting features of “small‐sized” BCCs, which can present smaller than 1 mm. However, few of these studies have characterized features of pigmented small‐sized BCC. The application of in‐vivo imaging such as dermoscopy and reflectance confocal microscopy (RCM) allows for the non‐invasive distinction of these lesions from benign and malignant melanocytic neoplasms, thereby reducing unnecessary biopsies.MethodsWithin one year, three patients presented to Oregon Health and Science University's dermatology clinic with pigmented lesions of concern measuring less than 2 mm that were histologically confirmed as pigmented BCC. We sought to characterize the features of these lesions in a case series with the non‐invasive imaging modalities of dermoscopy and RCM.ResultsAll cases presented clinically as a small, brown, macule on the face. Each of the three cases exhibited differing features on dermoscopy. With the application of RCM, we were able to visualize characteristic BCC features, prompting removal by shave biopsy.ConclusionTo our knowledge, no other study has reported dermoscopic and RCM features of a cohort of pigmented BCCs 2 mm in diameter or smaller. We propose to define BCCs of this size as micro‐BCCs. The variability of dermoscopic findings observed in our study, combined with the small size of these pigmented lesions, shows the utility of RCM as a non‐invasive diagnostic tool for pigmented micro‐BCCs.
