tinea corporis ( b35.6 ) caused by microsporum canis which is fungal species that causes numerous forms of disease .
though mostly well known for ringworm in pets , it is also known to infect humans .
we will report about a case , 22-year - old female , residing in a village , with typical changes of a mycotic infection caused by m. canis .
dermatological description can be summarized with polymorphic erythematous , papulosquamous changes , erosions mainly on genital organ and spread to the thighs and lower abdomen which are accompanied with itching and burning .
diagnosis b35.6 was determined on the basis of clinical appearance complemented with anamnesis , microscopic examination and culture .
dermatophytosis ( tinea ) infections are fungal infections caused by dermatophytes - a group of fungi that invade and grow in dead keratin ( 1 ) .
infection is limited to the dead layers of skin but encouraged by a damp and warm local environment .
the infection can be transmitted to humans by anthropophilic ( between people ) , geophilic ( from soil ) and zoophilic ( from animals ) spread ( 2 ) .
tinea cruris is three times more common in men than in women because of the scrotal anatomy ( 3 , 4 ) .
itching , rash and nail discoloration are the most common symptoms of tinea infection ( 2 ) .
tinea cruris , commonly referred to as  jock itch ,  involves the medial aspect of the upper thighs ( groin ) ( 5 , 6 ) .
complications such as secondary infection ( cellulitis and impetigo ) can lead to symptoms ( 2 ) .
more unusually the lesions can appear as overlapping concentric circles ( tinea imbricate ) ( 7 ) .
reactions to a dermatophyte infection may range from mild to severe as a consequence of the host s reactions to the metabolic products of the fungus , the virulence of the infecting strain or species , the anatomic location of the infection , and local environmental factors ( 8) .
fungal transmission occurs through direct contact with infected persons , animals , soil or fomites .
zoophilic sources should be identified ( if possible ) and treated to prevent human reinfection ( 9 ) .
the classic presentation of tinea infection , known as  ringworm ,  is a lesion with central clearing surrounded by an advancing , red , scaly , elevated border .
inflammation assists in colonization and may result in vesicles on the border of the affected area .
the presentations of tinea infections range from mild scaling and erythema to severe inflammation with bacterial superinfection .
the differential diagnosis : multiform erythema , annular granuloma , nummular dermatitis , rosea pityriasis , versicolor pityriasis , psoriasis , secondary syphilis , candidal intertrigo .
we report on a case diagnosed not directly due to delay of visiting a doctor by the patient because of stigma and prejudice attributed to local environment , lack of experience of the family doctor and specialist regional dermatologist in right diagnosis and treatment .
the case is a 22-year - old female , with mycotic infection in the genital area ( figure 1 ) .
female , 22 years old , lives in the village , hospitalized due to skin changes in the genital pubic part , thighs and lower abdomen , which are accompanied with extraordinary itching and burning .
the changes had started much time before but she delayed her visit to the doctor to the point when her condition deteriorated with fever and temperature .
the changes began with rash and itching presented in genitalia and then changes spread to areas around . in anamnesis , the patient denies that other members of the family have similar changes whereas she claims to own and have in family care a dog and a cat and no other domestic animals .
she comes from a low level of socio - economic status . in dermatological description ,
changes are polymorphic , plaques in the pubic area with erythematous fluorescence , pustules , erosions , crusts and papulosquamous changes in the shape of circles in thighs and lower abdomen which are accompanied with intensive itching .
the center of the circles is inactive while the surrounding is active with distinctive bordering line to the skin around . due to scratching because of itching
diagnosis was determined on the basis of clinical appearance , anamnesis , positive dermatophytes microscopic view and culture m. canis .
the patient was treated with general and local antimycotics ( terbinaphin 250 mg / day for 4 weeks ) , as well as with antibiotics according to sensitivity chart .
from the anamnesis of the reported case is emphasized the continuous itching which never stopped for the whole time being described as terrible and which corresponds to the literature . also , the humidity of the genital area itself , washing with water after each defecation and urination ( islamic belief tradition ) , was a suitable ground for the development of the disease .
the differential diagnosis was : multiform erythema , annular granuloma , nummular dermatitis , rosea pityriasis , versicolor pityriasis , psoriasis , secondary syphilis , candidal intertrigo but we were also based on clinical appearance , anamnesis complementing it with microscopic examination and fungal culture .
we consider that the report on the mentioned case will be beneficial to family doctors so they can complement their professional experience with more extensive knowledge on clinical manifestation , diagnosis and differential diagnosis .
 introduction : tinea corporis ( b35.6 ) caused by microsporum canis which is fungal species that causes numerous forms of disease . 
 it is part of a group of fungi known as dermatophytes . 
 though mostly well known for ringworm in pets , it is also known to infect humans . 
 this fact makes this pathogen both anthrophilic and zoophilic in nature . 
 microsporum canis is a communicable pathogen.case report : we will report about a case , 22-year - old female , residing in a village , with typical changes of a mycotic infection caused by m. canis . 
 dermatological description can be summarized with polymorphic erythematous , papulosquamous changes , erosions mainly on genital organ and spread to the thighs and lower abdomen which are accompanied with itching and burning . 
 diagnosis b35.6 was determined on the basis of clinical appearance complemented with anamnesis , microscopic examination and culture . 
 the patient was treated successfully with general and local antimycotics and antibiotics .
