Malignant trichilemmal carcinoma misdiagnosed with parotid gland malignant tumor.

Malignat proliferating trichilemmal tumor (MPTT) are rare tumors usually presenting in photo-exposed areas, especially on the face, scalp, neck,and dorsal part of the hand. Differential diagnosis include squamous cell carcinoma, basal-cell carcinoma, keratoacanthoma and malignant nodular melanoma, so that only incisional biopsy can lead to pre-operative diagnosis. We present case MPTT misdiagnosed with parotid gland malignant tumor that underwent radical surgical excision and adijuvant radiotherapy.

Surgical treatment of nasal non-melanoma skin cancer using full-thickness skin graft: can antiplatelet therapy be related to a better result?

AIM: The aim of this retrospective study is to evaluate if antiplatelet therapy in elderly patients undergoing surgical excision of nasal non-melanoma skin cancer and contemporary reconstruction with full-thickness skin graft can be related to a better vitality of the graft and consequently improved aesthetic result. MATERIALS AND METHODS: Patients affected by BCC or SCC of the nose that underwent surgical excision and contemporary reconstruction with full-thickness skin graft were divided into two groups according to antiplatelet therapy. Medications were performed 7 and 15 days after surgery. To asses engraftment, we clinically evaluated the percentage of vital flap recognizing 3 different results: less than 20%, between 20% and 80%, and more than 80% of vital surface. Finally, patients were asked to express a subjective evaluation of the aesthetic result using a numeric scale ranging from 1 to 10. Statistical analyses were performed with SPSS 15.0 for Windows. RESULTS: Twenty-four of the 36 eligible patients took antiplatelet therapy (Group 1). Statistical analysis was very close to demonstrate a significant difference between the two groups after the first evaluation (X2= 3.6; p-value = 0.0578) and it showed a clear significant difference between the two groups after the second evaluation (X2 = 13.5692 e p-value = 0.0002). The average value of the subjective evaluation conducted only on 32 of 36 patients, was 9.12. Any significant difference was observed between the two groups (p-value >0.1). CONCLUSIONS: Our preliminary results seem to suggest that antiplatelet therapy in elderly patients with non-melanoma skin cancer of the nose treated with surgical excision and contemporary reconstruction with fill-thickness skin graft could favor the graft vitality with low risk of bleeding. Further studies will be useful to determinate if antiplatelet drugs can be prescribed in the perioperative period to selected patients presenting risk factors for wound healing to increase the chances of engraftment.
