High Resolution Ultrasound in Cutaneous and Subcutaneous Lesions

Abstract

MATERIAL AND METHODS A prospective study of 100 patients in all age groups with skin lesions based on clinical data who presented to Bowring and Lady Curzon Hospital, Victoria Hospital and Vani Vilas hospital attached to Bangalore Medical College and Research Institute, Bengaluru, from November 2014 to May 2015 were subjected to HRUS examination. Study design: It was a Cross sectional study. Totally 100 patients were studied from November 2014 to May 2016. Inclusion criteria: All clinically suspected patients with superficial skin lesions. Exclusion Criteria: Patients with trauma. After taking Informed consent, all patients included A B S T R A C T Introduction: In the evaluation of cutaneous lesions, High Resolution Ultrasonography (HRUS) with color Doppler is useful as a safe, noninvasive, economical, and repeatable diagnostic procedure that can reduce and replace invasive procedures like fine needle aspirations and biopsies. Analysis of the skin surface allows the investigation of tumor and inflammatory diseases, the measurement of skin thickness. The objective of this study was to evaluate the role of HRUS in cutaneous lesions with histopathological correlation wherever possible. Material and Methods: A prospective study of 100 patients with skin lesions based on clinical data were subjected to HRUS examination. Collected data was analysed by descriptive statistics. Results: The study comprised of a total of 100 patients, out of which 75 were non-neoplastic and 25 were neoplastic lesions. The non-neoplastic lesions included Psoriasis, edema, lymph nodes and vascular malformations. The neoplastic lesions included 16 benign and 9 malignant cases. The observed HRUS and Doppler characteristics of these lesions are discussed in detail. Conclusion: HRUS is non-invasive, affordable, easily available, rapid imaging technology. It can be used to localize the skin lesion, generate differential diagnosis and to follow up known lesion.

Nano‐Cavity QED with Tunable Nano‐Tip Interaction

“…When spontaneous emission of a two level system was established by Einstein as a necessary mechanism for maintaining thermal equilibrium, it was initially believed to be an irreversible process in which the excited state energy is permanently lost to the infinite bath of available vacuum states . However, the subsequent development of cQED showed that spontaneous emission can be enhanced, suppressed, and even reversibly exchanged with a photonic cavity.…”

First clinical experience with a novel optical-ultrasound imaging device on various skin pathologies

“…Both devices showed malignant melanoma with a spindle-like, fusiform shape. This is one of the typical shapes that is also reported in the literature, [36][37][38][39] one that may be used to distinguish it from other skin lesions. The irregular shape of the metastatic melanoma recorded in the current study has also been noted in the literature.…”

“…37 Since such metastases cannot be seen on the surface they present a unique opportunity for the ultrasound to provide diagnostic assessment. 40 In the case of the basal cell carcinoma, several of the recordings showed hyperechoic spots within the lesion (Figures 6 and 8); this feature is noted in the literature as being one of the characteristic signs of BCC, 22,36,37,[39][40][41] which could therefore potentially be used to differentiate the lesion from other lesion types. In addition, since the outline of BCCs is difficult to assess optically, ultrasound may serve as an aid in treatment planning.…”
