Plasma cell myeloma is malignant disease of plasma cell in the bone marrow. Myeloma accounts for about 1% of all cancers. The solitary plasma cellmyeloma is rare tumors and account for less than 10% of plasma cell neoplasm. It is often progress to multiple myeloma at 30-40% despite successful local treatment with surgery and radiation therapy. We are reporting a case of solitary plasma cell myeloma on anterior maxillary region that developed after kidney transplantation and immunosuppressive therapy.]]>

Plasma cell neoplasms are generally categorized into four groups; multiple myeloma(MM), solitary plasmacytoma of the bone(SPB), plasma cell leukemias, and extramedullary plasmacytomas(EMP). These tumors may be further described as localized or diffuse in presentation. Localized plasma cell neoplasms are rare occurrences and include solitary plasmacytomas of the skeletal system, which account for 2-5% of all plasma cell neoplasms and extramedullary plasmacytomas of the soft tissue, which account for approximately 3% of all such neoplasms. A plasmacytoma is defined as any discrete, most likely solitary mass of neoplastic plasma cells either in the bone marrow or in various soft tissue sites. Diffuse lesions include the other two groups, multiple myeloma and plasma cell leukemia. The relationship between these processes has not yet been definitively characterized, but there appears to be a continuum in which both SPB and EMP often progress to MM. The patient was referred who had continuous deep throbbing bone pain and swelling on the left posterior gingival area of the mandible after extraction of the first and second molar. The result of intraoperative excisional biopsy of the lesion was confirmed as a plasmacytoma. And it revealed systemic multiple myeloma through the further diagnostic work-up. It is worth to report because of a rare case of multiple myeloma found in oral cavity as a form of plasmacytoma.]]>

Introduction: Psoriasis and some of its treatments such as methotrexate have been linked to the development of non-melanoma skin cancers including cutaneous squamous cell carcinoma (SCC). Chronic maque psoriasis, Koebnerization, and prolonged methotrexate therapy are some of the concerns that may impact wound healing and graft uptake when treating these patients. Case Report: We report a case of a 64-year-old male with a 32-year history of moderate to severe psoriasis continuously self-medicating with methotrexate for 30 years who presented with a solitary indurated tumor with ulceration on the right anterior leg. Histopathology result revealed acantholytic cSCC. The patient concomitantly has generalized psoriatic plaques that complicated the selection of donor site for the skin graft, and raised concerns on wound healing and graft uptake. He underwent wide excision surgery with gastrocnemius (medial head) flap and split thickness skin graft. Platelet-rich plasma (PRP) injections were utilized post-operatively to increase graft survival and donor site regeneration. Discussion The main risk factors for the development of cSCC for this patient are the history of chronic plaque psoriasis and chronic methotrexate therapy. These two can also complicate the success of grafting and wound healing for this patient. PRP was utilized to for better graft survival, faster wound healing, and prevention of Koebnerization.

Plasmacytoma is a plasma cell neoplasm that locally infiltrates a bone or spreads to extramedullary areas. A new World Health Organization criterion defines solitary plasmacytoma of bone as a localized bone tumor consisting of plasma cells identical to those seen in plasma cell myeloma, which is manifested as a solitary osteolytic lesion in a radiological evaluation. Primary tumors of the sternum are generally malignant, and solitary plasmacytomas of the sternum are very rare tumors. We present herein the case of a patient who had a primary sternal tumor with solitary plasmacytoma and no evidence of multiple myeloma.
