 Eccrine  porocarcinoma  is  a  rare  malignant  adnexal  tumour  of  ductal  portion  of  eccrine sweat  gland.  It  commonly  occurs  in  older  age  group,  common  site  being  lower  extremities  and  rarely  in  scalp,  face,  ear,  trunk  and  upper  extremities.  Local  recurrence  and  metastasis  to  skin,  lymph  nodes,  viscera  and  bone  may  occur.  Surgery  is  the  treatment  modality  of  choice.  Metastatic  lesions  can  be  treated  with  chemotherapy.  We  report  an  unusual  case  of  eccrine  porocarcinoma  of  scalp  in  a  85  years  old  female  patient  arising  over  right  fronto–parietal  region.  Diagnosis  is  quite  challenging  by  clinical  examination  alone,  hence  histopathology  and  immunohistochemistry  form  the  mainstay  for  early  diagnosis  and  treatment.  Till  date,  only  one  case  of  eccrine  porocarcinoma  on  fronto–parietal  region  has  been  described  in  literature  akin  to  our  case.
