What is the Mohs Surgery (CMM) and what are the advantages compared to other therapeutic modalities?

It is the technique that has revolutionized the dermatological tumor oncological surgery and is considered "the Gold Standard". Unlike conventional surgery, which does not give absolute guarantees of healing. CMM allows tumor resection respecting healthy tissue and an immediate three-dimensional histological control with a cure rate of 99% in primary tumors and 95% in those previously treated or recurrent. In addition, it allows the reconstruction of immediate plastic surgery in the same surgical act.


Is hospitalization necessary?

Hospitalization is not required. The surgery is performed in dermatological operating rooms with the adjoining laboratory, thus allowing us an agility and speed in the realization of the technique.

What can be detected with the extraction of the tissue?

We as dermatopathologists examine the tumor tissue immediately with tissue freezing and specific chlorinations that allow us to distinguish the true tumor from non-tumor simulation images. That is why it should be done by a surgeon specialized in CMM and also dermatopathologist.


What possible complications can occur?

The failure of the technique is determined by errors of the surgeon, by poor orientation of the piece, by technical failure to cut with the cryostat, histopathological misinterpretation or a defective reconstruction with complications.


By analyzing the part and be positive, Another extraction is performed?

Of course, it is a technique that goes through successive stages, removing only the positive foci. Only against Cutaneous Sarcomas, we performed a double control and immunohistochemistry.


What type of post-operative should be followed?

The ordinary surgery: a week for the removal of the skin sutures and regular checks, first a month, then every six months and then once a year.
