RESUMO
In this study, a case of a 56-year-old woman with cutaneous metaplastic carcinoma in the neck is reported. It harbored basal cell carcinoma, squamous cell carcinoma, and sebaceous carcinoma, as well as osteosarcoma (with fibroblastic, osteoblastic, aneurysmal bone cyst-like, and chondroblastic patterns). To our knowledge, the literature does not mention sebaceous carcinoma in cutaneous metaplastic carcinoma. Epidemiology and intact mismatch repair proteins of this case support sporadic pathogenesis for this neoplasm. The patient has been followed up for 3 years after surgery with free margins, and no local recurrence or distant metastases have been observed.

Abstract: BACKGROUND: Angiosarcoma is an aggressive, malignant neoplasm of vascular or lymphatic origin. Herpes virus 8 (HHV-8) is a member of the herpes family with a tropism for endothelial cells and it has been proven to induce vascular neoplasms, such as Kaposi's sarcoma. The role of HHV-8 in the pathogenesis of angiosarcoma has not been well defined. OBJECTIVE: To investigate the relationship between the presence of HHV-8 and angiosarcoma. METHODS: In this study, the team investigated the relationship between the presence of HHV-8, as determined by polymerase chain reaction, and angiosarcoma, using samples from patients with epidemic Kaposi's sarcoma as controls. RESULTS: While all control cases with epidemic Kaposi's sarcoma were positive for HHV-8, none of the angiosarcoma cases was. CONCLUSION: These findings support most previous studies that found no association between HHV-8 and angiosarcoma.
