A 44-year-old male was diagnosed with acute myeloid leukemia with a complex karyotype. He underwent bone marrow transplantation using an HLA 6/6 antigen-matched sibling donor, but developed chronic graft-versus-host disease (cGVHD) with skin erythema and oral and esophageal lichen planus changes. Treatment with a combination of prednisolone and cyclosporine was initiated on day 646 after transplantation, but oral symptoms persisted. The patient developed bilateral osteonecrosis of the lower jaw after extraction of the lower left and right molars on days 2,861 and 3,339, respectively. As the disease gradually progressed, segmental mandibular osteotomy was performed. Biopsy specimens demonstrated proliferation of squamous epithelial carcinoma cells in the bilateral gingiva and lower jaw bone, which confirmed the diagnosis of bilateral gingival squamous cell carcinoma. Thus, gingival squamous cell carcinoma should be considered as a differential diagnosis in post-transplant patients with refractory osteonecrosis of the jaw during the course of cGVHD.

A carcinoma derived from stratified squamous epithelium. It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
A mixed adenocarcinoma and squamous cell or epidermoid carcinoma.
Unusual tumor affecting any site of the body, but most often encountered in the head and neck. Considerable debate has surrounded the histogenesis of this neoplasm; however, it is considered to be a myoblastoma of, usually, a benign nature. It affects women more often than men. When it develops beneath the epidermis or mucous membrane, it can lead to proliferation of the squamous cells and mimic squamous cell carcinoma.
A skin carcinoma that histologically exhibits both basal and squamous elements. (From Dorland, 27th ed)
There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and malignant melanoma. Basal cell carcinoma Basal cell carcinoma, or BCC, is a cancer of the basal cells at the bottom of the epidermis. It’s very common ...
