Clinical presence of dermatophytosis of the penis and scrotum has been studied in 256 patients with dermatophytosis elsewhere in the body. 54 patients showed the dermatophytosis of the penis and / or scrotum in total. Of these 9 patients had only tinea penis. 10 had only scrotal involvement while 24 had both. All the 54 patients had tinea cruris. Maximum (70.37%) patients belonged to 21-40 years age group among those who had dermatophytosis of the penis and / or scrotum. Trichophyton spp. was the commonest dermatophyte found on culture. Wives of the patients were free from any clinical sign or symptoms of the involvement of the genitalia.

| Introduction|| |
Dermatophytosis of the penis and scrotum has been regarded as a rare entity. Hebra (1860) commented, "When a patient thus affected lies with both thighs abducted and flexed, the whole extent of the disease is visible at a glance and it is then seen how remarkably exempt the penis and scrotum remain".  The same opinion has been published by many other authors. , But on the other hand studies from different researchers showed that the dermatophytosis of the penis and scrotum is not very rare at all. , This controversial opinions regarding the rarity of this entity prompted us to undertake the task of finding out the incidence of clinically present dermatophytoses of the penis and scrotum in individuals with dermatophytosis of the skin.
| Materials and Methods|| |
All the 256 patients attending our department during the period of 1st July to 31st August, 1993, having dermatophytosis any where in the body were, asked about the history regarding the symptoms, chronicity, recurrence, personal habit, occupation, marital status, sexual practice, presence of diabetes, tuberculosis, history of local/systemic usage of steroids, history of similar disease in the spouses etc. Then physical examination was done to see the presence of involvement of the genitals. Complete blood count, ESR, blood sugar estimation, ELISA test for HIV infection, chest X-ray etc. were done. Scrapings were taken for KOH smear examination and cultures were done in Sabouraud's medium.

All the 256 patients with dermatophytosis of the skin belonged to the industrial zone of Ahmedabad city of Gujrat. Of these 54 (21.09%) showed the involvement of the penis and / or scrotum. Their age distribution has been shown in the [Table - 1]. Of the 54 patients having dermatophytosis of the penis and scrotum, maximum patients (40.74%) belonged to 21-30 years age group, followed by 31-40 years age group (29.63%). No patients belonged to age group below 10 or above 50 years of age.
Typical ring like lesions with active border were seen in lesions on the penis, but scrotal lesions showed more scaling. Every patient complained of itching. No patient gave any history of diabetes, tuberculosis or any other immunosuppressive condition in the recent past; 4 patients gave history of local steroid application.
The type of involvement has been shown in the [Table - 2]. Of the 54 patients, penile tineasis only was found in 9 patients (16.67%), scrotal tineasis in 10 patients (18.52 0sub/0), both penile and scrotal lesions were found in 24 patients (44.44%). All the patients having tinea infection of the penis and/or scrotum had infection of the inguinal intertriginal area. Associated tinea corporis was found in 21 patients (38.89%). Nail or scalp involvement were found in none.
All the laboratory investigations to determine any systemic disorder were within normal limits. Scraping and smear with KOH was found positive in 54 patients (100%). Culture was found positive in 43 patients (73.63%). Of these 33 patients (76.74%) had Trichophyton rubrum infection, 9 patients (20.09°i%) had T. Mentagrophyte infection and 1 patient (2%) showed E. floccosum infection.
Out of 54, 40 patients were married and had active sexual life. But none of their wives had any history suggestive of the dermatophytosis of the genitalia and were found free from the same on clinical examination.

In this study most of the patients with penile and / or scrotal dermatophytosis (70.37%) belonged to 21-40 years age group which is in consonance with the study of Phadke et al.  Surprisingly no patients belonging to age group below 10 or above 51 showed the dermatophytosis of the genitalia which was also observed by Pandey et al.  Although Arnold et a1  could found no case of dermatophytosis of the genitalia and Hay et a1  maintained that penile involvement occured rarely, our observation shows an incidence of 21.09% of the total patients examined this to be a relatively common entity. This low incidence in the Western countries may be due to difference in the climate and socio economic condition. Climate plays an important role has been noted by us also because upsurge of the cases was noted during the rainy season of the year (July-August) when the humidity was more that 95%. This was superadded by the hot environment of the factory where most of our patients worked. Solitary involvement of the penis or scrotum without the involvement of the crural region was not found which showed that the infection probably started in the crural region and spreaded later to the genitalia. Some authors attributed the rarity of the genital involvement to the capric acid and some fungistatic serum factor and sebum ,. In this study another important observation was the absence of dermophytosis of the genitalia in the wives of the patients. Although we have not included female patients in our study but it is our common observation that the labia of the females are exempted from the tinea infection. Similarly no patient was found below 10 years or above 50 years of age. These peculiarity in the age and sex group involvement requires further investigations.
So it can be concluded that the dermatophytosis of the genitalia is not that rare as it has been thought to be, particularly in a tropical country like India.
