A case of upper gingiva carcinoma with chronic graft-versus-host disease after allogenic bone marrow transplantation

Multiple oral squamous cell carcinoma 6 years after allogeneic stem cell transplantation complicated with chronic graft-versus-host disease: A case report

Oral squamous cell carcinoma is a potential long-term complication after hematopoietic stem cell transplantation. This may be related to mechanisms including radiation and chemotherapy regimens, chronic graft-versus-host disease, inflammation, and prolonged immunosuppression. The current case describes the development of multiple oral white thick keratotic lesions in the floor of the mouth and the tongue 6 years after hematopoietic stem cell transplantation complicated with chronic graft-versus-host disease. A biopsy performed with histopathological analysis revealed a well-differentiated squamous cell carcinoma. The patient was treated by subtotal glossectomy, bilateral neck dissection, and flap reconstruction. This report highlights the significance of the routine oral examination of long-term surveillance post hematopoietic stem cell transplantation to ensure early detection of these tumors at potentially treatable stage.

Two Lip Carcinomas following Allogeneic Hematopoietic Stem Cell Transplantation: A Case Report and Literature Review

Background

Secondary solid cancers are severe complications in patients who have undergone allogeneic hematopoietic stem cell transplantation (AHSCT) for malignant and nonmalignant lymphohematopoietic diseases.

Objective

The aim of this work was to report a case of two lip carcinomas following AHSCT and to warn doctors about the importance of regular check-ups of patients who have received HSCT. Observation. A 57-year-old man was referred by the dermatology department for the management of exophytic budding lesions on the lower lip evolving since 5 months. The patient was in complete remission following allogeneic bone marrow transplantation for acute myeloid leukemia since five years. Clinical and histological findings confirmed the diagnosis of a squamous cell carcinoma of the two lesions.

Conclusion

It is of paramount importance to seek an oral squamous cell carcinoma in the presence of persistent lesions in HSCT recipients.

HPV-related oral dysplasia in a multiple myeloma patient after stem cell transplantation

The development of dysplastic changes in oral epithelial lesions is a potential long-term complication after hematopoietic stem cell transplantation (HSCT). This may be related to mechanisms including radiation and chemotherapy regimens, chronic graft-versus-host disease (cGVHD), inflammation, and prolonged immunosuppression. The current case describes a 54-year-old male with multiple myeloma treated by autologous and allogenic HSCT followed by development of cGVHD (mouth, skin and the eyes) with the complaint of diffuse white lesions on the buccal mucosa, tongue, and palate. A biopsy performed with histopathological analysis revealed moderate to severe epithelial dysplasia with hyperkeratosis, positive for p16INK4A as a surrogate marker for human papillomavirus (HPV). Our finding suggests a possible association of oral dysplasia and HPV in patients after receiving allogenic HSCT with the necessity of more clinical follow-ups for those patients that may be at a higher risk for the development of oral dysplasia associated with HPV.
