i have no idea!

a 70 years old man presented with this lesion in his rt inguinal region

the lesion was epidermal with some scaling and it odors like psedomona...

it was non tender and developed in only 2 days

his past medical history was not remarkable but the BS was near 300

after washing the wound with normal salin and some rubbing with gaz, it become like this

he went under skin biopsy and transferred to dermatology ward and i didn't find him

so he is still a mystery
