Introduction:
Malignant eccrine poroma is a very rare tumour of the sweat glands with high malignancy and presenting with a polymorph clinical and histological picture.
Case Report:
We describe the case of a 99-year-old patient with a malignant poroma on the buttock. Despite the large size of the tumour, no metastasis was found with standard examination techniques. Radical excision and defect closure with a Limberg flap was performed.
Result:
The healing course was uneventful and without complications.
Conclusion:
The malignant poroma is a tumour of high malignancy which can easily be misdiagnosed because of its different forms of presentation. Radical surgical therapy is the only known effective treatment.
