Introduction:
Dermoscopy of mucosa is known as mucoscopy. Mucoscopy can aid in delineating minute aspects of mucosal lesions and will guide in the differentiation of similar-looking lesions. To date, there are only a few studies on mucoscopy of genital dermatoses especially from India.
Aim And Objectives:
The study aims to describe mucoscopic features and correlate histopathologically in various genital mucosal diseases.
Materials And Methods:
The study was conducted in a tertiary care center in Central India after IHEC approval between October 2020 and April 2022, and the sampling technique was based on a convenience purposive method. Any genital mucosal diseases were included in patients above 18 years of age. Sexually transmitted diseases in general were excluded, however, warts and molluscum contagiosum were included. All patients fulfilling the inclusion criteria were examined after proper informed consent, and the clinical images were photographed using iPhone 11. Dermoscopic images were taken using a DermLite DL4 dermoscope in polarized mode at 10X magnification.
Results:
A total of 206 patients were recruited, and mucoscopy features were analyzed. Dermoscopic findings of physiological conditions such as vestibular papillomatosis, pearly penile papules, and Fordyce spots were evaluated. Inflammatory conditions such as lichen planus, pemphigus, and psoriasis were analyzed. Mucoscopy of lichen sclerosus showed white structureless areas (100%), follicular plugs (35%), as well as dotted and linear vessels (80%). Circinate balanitis revealed regular red dotted vessels (100%), coalescing pustules in annular and polycyclic patterns (90%). Squamous cell carcinoma of the penis showed ulceration, serpentine, looped vessels, white structureless area, and yellow-brown crust in a pink background.
Limitations:
In our study, because of the inclusion of various diseases, sample size was inadequate, biopsies were not performed in all cases, and variations in mucoscopic features in patients who are already on therapy could not be assessed. Haziness while capturing pictures because of mist formation was hindering the quality of pictures. As patients with premalignant and malignant cases were less, the predicting features for malignant transformation or pathognomoniic signs could not be assessed.
Conclusion:
Various dermoscopies have been studied extensively, but the mucoscopy is still a gray area. The results of this study revealed the dermoscopic features of various genital disorders and histopathological correlation in few cases. However, biopsy was not performed in all mucosal disorders; hence, conclusive correlation could not be extrapolated.
