RESUMEN
The Muir-Torre Syndrome is a rare genodermatosis, defined by the occurrence of sebaceous neoplasia and internal malignancies and caused by mutations in the mismatch repair gene. We describe the case of 58-year-old man who, over the course of several years, had multiple skin lesions and colon cancer. The syndrome was diagnosed using Sanger sequencing, which allowed us to find the causative mutation.
RESUMEN
UNLABELLED: Frontal pneumosinus dilatans is a rare entity that is documented only by a few reports. It is an abnormal expansion of the aerated frontal sinus, with sinus walls of normal thickness. The expansion of the bone may be generalized or focal. It is not only an aesthetic problem but may also have functional consequences. We herein present the case of a 23-year-old woman who had been referred to the maxillofacial and plastic unit in Sousse (Tunisia) complaining of a prominence on her right supraorbital region and forehead. The cause was unknown and there were no functional problems. Computed tomography showed a large pneumatized frontal sinus and confirmed the resulting bony prominence. The patient was taken to the operating room, where the frontal and supraorbital regions were exposed through a bicoronal incision. The anterior wall of the right frontal sinus was removed, and was divided into segments that were then fixed in the desired position using a titanium mesh plate. Excellent results were obtained, and the patient had no complaints and was satisfied with her appearance. She remained well two years postoperatively. Pneumosinus dilatans is an entity every plastic surgeon should be aware of because its treatment falls within the realm of craniofacial surgery. The etiology remains unclear, and surgical management is directed toward surgical exploration of the sinus to ensure recontouring of the anterior table of the frontal sinus to correct any cosmetic deformity. Several authors have published different surgical techniques. LEVEL OF EVIDENCE: 5 Therapeutic.
