We report a case of difficult-to-control mycosis fungoides (MF), where the role of the dental surgeon was crucial for the control and prognosis of the disease. A 62-year-old female patient diagnosed with MF had a previous record of red patches and small raised bumps on the face, along with a cancerous growth in the cervical and vulvar region. The patient was initially treated with methotrexate and local radiotherapy without resolution. Chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone was then started (CHOP protocol). The dental team of a reference hospital was consulted to evaluate swelling in the anterior region of the palate, which had been developing for two months, reporting discomfort when eating. The role of the dentistry team was fundamental in the differential diagnosis of oral lesions with dental infections, second neoplasia, or even a new site of disease manifestation, in addition to controlling mucosal changes resulting from chemotherapy. After ruling out dental infection, the dentistry team performed a lesion biopsy to confirm the diagnosis. The histopathological and immunohistochemical analysis showed atypical lymphoid infiltration of T cells (CD3+/CD4+/CD7-/CD8-), coexpression of CD25, and presence of CD30 cells, corresponding to the finding for MF. Identifying CD30 + allowed for a new chemotherapy protocol with brentuximab vedotin (BV) combined with gemcitabine. This protocol effectively controlled MF, which previous protocols had failed to do. The diagnosis by the dental team was essential for therapeutic change and improvement of the patient’s clinical condition without the need for invasive medical procedures.

Introduction A primary cutaneous CD-30 positive T -cell lymphoproliferative disorders are rare and heterogeneous group of primary skin tumors, which include primary cutaneous anaplastic large cell lymphoma (PCALCL) and lymphomatoid papulois. Case report We report a rare an atypical case of PCALCL with an aggressive and refractory behavior that occurred in the lip vermilion, and that had been initially diagnosed as aggressive herpes. The lesion was recurrent and refractory to the CHOEP chemotherapy protocol followed by radiotherapy, but after hyper CVAD (acronym) + brentuximab with a considerable improvement. After 4 cycles of hyper CVAD plus brentuximab, the patient underwent 100% compatible sibling bone marrow transplantation, with success in the procedure. Conclusion Primary cutaneous anaplastic large cell lymphoma is a rare disease of difficult diagnosis and may be confused with chronic infectious diseases, postponing treatment.
