Myelomatous involvement of the maxilla is rare. A case is presented where bilateral enlargement of the maxillary tuberosities lead to a diagnosis of plasma cell myeloma (multiple myeloma) in an edentulous 54-year-old female.

Periapical actinomycosis is a relatively rare form of cervicofacial actinomycosis, which typically involves the periapical region with subsequent potential spread to the jaw bones. We hereby present two cases of periapical actinomycosis. Both patients presented with jaw pain and "holes" in their gum and lacked the characteristic clinical features commonly seen in cervicofacial actinomycosis such as jaw mass, draining ulcers, sinuses and fistulae. The first patient was an immunocompetent host with chronic stable medical conditions but with a rather bad dentition requiring multiple recent teeth extractions. The second patient was edentulous, had refractory multiple myeloma, was on low-dose chronic steroids and pomalidomide therapy and therefore relatively immunocompromised. Both cases of actinomycosis were diagnosed by jaw bone histopathology, which showed characteristic sulfur granules and embedded Actinomyces-like organisms. The two patients had excellent clinical response to six months of penicillin therapy without any need for surgical intervention. The cases remind clinicians of including actinomycosis in the differential diagnosis of periapical lesions and illustrates the possibility of achieving cure with non-surgical treatment.

Dental implant placement in patients with multiple myeloma undergoing bisphosphonates therapy could be accomplished; however, it can turn into a successful treatment for edentulous area and functionally stabilized for many years. But a meticulous case selection, proper medical consultation with physician, minimally invasive surgery, and other cautions must be considered.

Actinomycosis is an uncommon, chronic suppurative granulomatous infection and needs to be considered as a differential diagnosis. A 56-year-old woman with a background of type 2 diabetes mellitus and breast carcinoma was referred to the Oral and Maxillofacial Surgery 2-week wait clinic, regarding a tender sublingual mass and firm erythematous swelling in the right submandibular and submental region. This was slowly progressive and had not responded to oral co-amoxiclav. An orthopantomogram showed a well-defined radiolucency and smaller radiolucent lesions throughout the edentulous right body of the mandible. A contrast-enhanced CT confirmed a right submandibular abscess communicating with cavitating lesions. The differentials included osteomyelitis, bony metastases, multiple myeloma or other cystic lesions. The patient underwent incision and drainage of the abscess, alongside biopsies, and intravenous co-amoxiclav was given. Microbiology cultures confirmed the presence of Actinomyces israelii and a diagnosis of cervicofacial actinomycosis with mandibular osteomyelitis. The patient was successfully treated with prolonged antibiotics.
