RESUMO

Spindle cell squamous cell carcinoma (SpSCC) is a rare biphasic malignant neoplasm, uncommonly affecting the oral cavity. The SpSCC diagnosis is difficult, especially when it exhibits inconspicuous morphology, inadequate tissue sampling, or association with an exuberant inflammatory reaction. Post-radiotherapy recurrent SpSCC occurring at the same site of conventional SCC is a rare phenomenon. A 59-year-old man was complained of "painful injury on the tongue" with 20 days of duration. He reported smoking and alcohol consumption. Medical history revealed conventional SCC on the tongue treated with surgery and radiotherapy 10 years ago. Intraoral examination showed a polypoid lesion with ulcerated areas, measuring 3 cm in diameter, on the tongue and floor of the mouth, at the same site of previous conventional SCC. The microscopical analysis showed small foci of carcinomatous component admixed with an exuberant inflammatory reaction. Immunohistochemistry highlighted the sarcomatoid component. Both malignant components were positive for EMA, CD138, p40 (deltaNp63), p63, and p53. Moreover, CK AE1/AE3 evidenced the carcinomatous component, whereas vimentin stained the sarcomatoid component. The Ki-67 was >10%. The current case emphasizes the importance of immunohistochemistry in the differential diagnosis of SpSCC from mimics and documents a rare complication of Ionizing Radiation.

RESUMO

Dental transplantation is an alternative for rehabilitation with a high success rate. This article presents a clinical case of autogenous dental transplantation in a 17-year-old male patient undergoing treatment for Class III dento-facial deformity. After 32 months followup, low-cost rehabilitation was possible, and without prejudice to ortho-surgical treatment.

RESUMO

Oral rehabilitation with osseointegrated implants is frequently the best alternative for replacement of lost teeth. Several techniques and materials allow achievement of excellent function and esthetics. In the case of maxillary or mandibular atrophy, extensive grafting may be necessary before implants can be properly placed. This is a case of maxillary reconstruction with autogenous iliac crest bone grafts, followed by placement of guided implants. After integration of the grafts, planning and insertion of implants allowed installation of an implant-supported prosthesis, recovering the morphology, function, and esthetics.
