The present study demonstrated that the number of males affected was slightly higher, with a male-to-female ratio of 1.2:1, in accordance with Pottipati et al.’s study (
9), which reported a ratio of 1.24:1. This slender male preponderance might be attributed to associated stigma among females, along with consultation for genital complaints in other departments, such as gynecology, rather than dermatology.
Of the adult patients, 67.5% were legally married, and 54% of the unmarried individuals were involved in sexual activities. Among sexually active individuals, a ‘ping-pong effect’ might be observed, wherein sexual partners recurrently re-infect each other with the same STI if not treated concurrently. This emphasizes that notification, screening, and simultaneous treatment of the partner are imperative for STI control. In the current study, one in four MSM (bisexual) patients was HIV-seropositive (25%), highlighting the higher prevalence of STIs, including HIV, in this high-risk group (
10). The MSM individuals should, therefore, be prioritized and counseled about safe sexual practices for risk reduction.
Tekam et al. (
11) reported that over half of their participants presented with STIs. In the present study, the proportion of non-STI cases (53.75%) was marginally higher, with a higher number of males in the sexually active age group, potentially due to a greater propensity for high-risk sexual behavior. The presence of one or more risk factors was significantly higher in males (69.4%) than in females (30.6%).
The majority of non-STI cases had lesions of fungal etiology, with tinea cruris leading the list. Pottipati et al. (
9) and Tekam et al. (
11) reported vitiligo and candidial balanoposthitis as the most common non-STI lesions, respectively.
Similar to Marcos-Pinto et al.’s study (
12), the present study showed that SCC was the most frequent malignant lesion. An interesting case involved a 26-year-old HIV-seropositive woman presenting with a fungating growth over labia majora, who was diagnosed as poorly differentiated SCC upon histopathology. Human papillomavirus (HPV)-DNA polymerase chain reaction (PCR) was positive for subtype 16. Human papillomavirus types 16 and 18 are classified as high-risk HPV (HR-HPV), and their association with genital warts is strongly linked to cervical dysplasia (
13). Therefore, in the case of genital condyloma, HPV typing holds predictive value for the development of genital SCC, and its screening and timely management are imperative to avert genital malignancies.
Another notable case was a 49-year-old male diabetic who presented with ulcers over the penile shaft, with purulent bloody urethral discharge for one month. He had a history of a recent dorsal slit procedure performed in view of impending penile gangrene. Upon examination, multiple preputial ulcers and segmental gangrene on the glans penis were observed. The demonstration of characteristic fungal elements on potassium hydroxide mount and histopathology led to the diagnosis of mucormycosis, a potentially life-threatening opportunistic infection caused by Zygomycetes, typically affecting immunocompromised individuals. Uncontrolled diabetes likely predisposed him to this condition. Genital mucormycosis is extremely rare.
The majority of patients with STIs had lesions of viral etiology (42.5%), with herpes genitalis being the most common, consistent with Tekam et al.’s findings (
11). Nevertheless, Wildsmith et al. (
14) reported chlamydia as the foremost cause. The higher prevalence of herpes reflects the changing trends in STI patterns in India (
15). This finding might be attributable to the syndromic approach (
16) implemented for their management instead of the identification of specific etiology.
Tekam et al. (
11) demonstrated that herpes genitalis and genital warts were the predominant STIs in males and females, respectively. In the present study, the most common STI in males was herpes; however, in females, it was vulvovaginal candidiasis, consistent with Elfaituri S’ findings (
17).
In the present study, one or more identifiable risk factors were present in 77.5% of subjects, with the predominant ones being lack of circumcision (51.25%), unprotected intercourse (22.5%), HIV seropositivity (18.75%), and multiple sexual partners, symptomatic partner, and poor personal hygiene (8.75% each). Wildsmith et al. (
14) reported that 64% of patients had one or more identifiable risk factors, including multiple sexual partners, symptomatic partners, and unprotected intercourse.
Among those with risk factors, the majority (87.1%) had a primary diagnosis of infectious etiology. Therefore, identifying and educating patients regarding modifiable risk factors might be instrumental in minimizing genital diseases.
Only 5.3% of patients in the STI category and 8.7% in the non-STI category were circumcised. Circumcision has been demonstrated to provide protection against STIs and penile cancer (
18). Circumcision reduces the risk of oncogenic HPV by 32-35% and that of HR-HPV, bacterial vaginosis, and trichomoniasis in female partners by 28%, 40%, and 48%, respectively (
19,
20).
The present study revealed that 86.25% of patients had a primary diagnosis of infectious etiology, emphasizing that infectious diseases still contribute considerably to the burden of genital diseases. The maximum number of cases belonged to the age group of 21 - 30 years (41%), suggesting a higher probability of indulgence in high-risk behavior within this age group.
Pruritus was the most common symptom, as also observed by Pottipati et al. (
9). The second-highest number of patients were asymptomatic. The most frequent examination finding was ulcers, often an incidental feature on clinical examination rather than a presenting complaint. The lack of symptoms and their obscure location lead to genital lesions remaining unnoticed and neglected until these patients present at advanced stages with complications that could have been averted. This finding highlights the importance of meticulous clinical examination in the management of genital diseases.
Among HIV-seropositive patients, 63.3% had non-STIs, contrary to a previous study (
11) in which 77% of HIV-seropositive patients had STIs. The human immunodeficiency virus is known to be associated with STIs (
21); however, its relationship with non-STIs has still not been established and warrants further research.
All three adolescent females in the current study were post-pubertal, and two of them were married despite being younger than the legally permissible age of 18 years. This finding highlights the inherent risks of early-age sexual debut, particularly the acquisition of STIs, such as condyloma acuminata and candidiasis, as encountered in the studied adolescent subjects. It also supports the need for immunization of all young males and females with HPV vaccines.
All three pediatric subjects were females with non-STI dermatoses (ecthyma gangrenosum, vulvovaginal candidiasis, and lichen sclerosus et atrophicus). The presence of STIs in the pediatric population warrants thorough scrutiny for sexual abuse. However, no such history could be elicited in any of these children. Mekala et al. (
22) reported that among pre-pubescent females, vulvovaginitis was the most common.
5.1. Strengths and Limitations
This study is novel, offering a comprehensive clinico-etiological and demographic compilation of all genital lesions (both venereal and non-venereal) across age and gender. It was impossible to find any similar studies documenting all the variables to compare to the findings of the current study. The limitation was the small sample size, owing to a brief period of data collection. This issue probably resulted in a small number of cases in each category; therefore, statistical analysis could not reflect the association between various parameters. In some cases, elaborate sexual history could not be elicited due to awkwardness and stigma, which might have led to recall bias and missing data.
5.2. Conclusions
This study emphasizes that although STIs remain a prominent cause of genital lesions, particularly in young sexually active individuals, non-STIs also contribute significantly and should be focused on. Therefore, measures for their prevention and control ought to be intensified. A detailed history is imperative to identify risk factors among these patients. Partner notification, screening, and treatment are necessary for the control and management of STIs. It is fundamental to perform an adequate anamnesis, beginning with particulars of sexual contacts (including abuse), fortified by meticulous clinical examination and relevant laboratory investigations for accurate diagnosis and management. Screening for HIV should be performed in all patients with genital lesions, especially with STI etiology. It is paramount to identify venereal dermatoses in children and adolescents since it might provide vital clues for sexual abuse. Genital lesions remain a major public concern and a source of embarrassment for patients, highlighting the unmet need for community sensitization to alleviate the stigma and counseling regarding safer sexual practices.
