A number of dermatoses and skin tumors affect the genitalia in
an unique (or) distinct manner that they warrant separate discussion.
The normal characteristics of common dermatoses are modified on
genitals. For most of them this may be the only one of the many sites
involved while in others it may be predominantly confined to the
genitalia. The features are frequently modified by moisture in local
environment.
The genital area differs between the sexes being the good
example of regional human variation. There is a considerable
variability in size, shape, pigmentation and amount of hair
distribution. Moreover, perineal area is plentifully endowed with
functional eccrine, non-functional apocrine sweat glands and
holocrine sebaceous glands usually in association with hair follicles.
In males natal cleft, perianal skin, distal penile shaft, prepuce
and glans penis are devoid of hair. Circumcision an alter the incidence
and appearance of dermatoses on the glans and corona. Rugose and
thin skin of scrotum allows excellent penetration of topical agents.

In females vulva is the anterior portion of perineum within it
are the clitoris, urethra and vagina. Vulva itself is subdivided into
mons pubis, labia majora and labia minora. Medial aspect of labia
majora is smooth and hairless with numerous sebaceous glands.
Vulvar vestibule which extends between clitoris anteriorly to the
posterior fourchette and laterally bounded by labia minora is the
major site for inflammatory disorders.
AIMS :
1. To study about the common dermatological disorders
affecting the genitalia.
2. Age and sex relation ship of the genital dermatoses.
3. Clinical presentation of the genital dermatoses and
confirmation by relevant histopathological and
microbiological tests.
CONCLUSION:
1. The common non venereal genital dermatoses in males in the order of
frequency were vitligo, fungal infections, scabies and tumors whereas in
females were vitiligo and fungal infections.
2. Other dermatoses were Lichen nitidus, Seborrheic dermatitis, Plasma cell
balanitis, Hansen’s disease, Fournier’s gangrene, Filariasis, Paraphimosis,
Molluscum contagiosum, Wart, Hidradinitis suppurativa, Neurofibroma,
Follicultis , Fox Fordyce Disease and Mondor’s disease.
3. Sex ratio was found to be 4.7:1 (Male :Female).
4. Non venereal genital dermatoses were more common in males, seen in the
age group of 31-40 years. Children less than 10 years (3.75%) and adults
older than 60 years (1.25%) were the least affected groups.
5. Most of the patients (80%) presented for their gential lesions.
6. The commonest sites of involvement in males were scrotum (50%)
followed by prepuce and shaft of penis(36%). In females labia majora
(93%) followed by labia minora (57%) were found to be the commonly
involved sites.
7. 45% of patients with genital dermatoses had associated skin lesions of the
same condition.
8. The non venereal genital dermatoses had classical morphology and
histopathology in almost 90% of cases.
9. Hence thorough knowledge about the classical morphology and
histopathological features is essential for the accurate diagnosis and
management
