A Novel Case of Providencia rettgeri Osteomyelitis Presenting in the Frontal Bone.

Osteomyelitis of the skull is a particularly life-threatening condition. Infections are usually at the base of the skull and typically occur following dissemination from another site, such as the external auditory canal. Typical organisms include Pseudomonas and Staphylococcus species. This paper demonstrates an unusual case of osteomyelitis of the frontoparietal bone, as well as the first published case of Providencia rettgeri causing cranial osteomyelitis in humans.

Paraneoplastic-Like Syndrome in a Breast Cancer Patient With a Negative Paraneoplastic Panel: A Case Report.

Breast cancer is a leading cause of cancer death in the United States, with an increasing incidence in recent years. Paraneoplastic syndromes are uncommon but increasingly recognized complications of many types of cancer, including breast cancer. Here, we describe a case of a patient presenting with confounding symptoms, who was diagnosed with breast cancer and believed to have a paraneoplastic syndrome despite a negative paraneoplastic panel. This case underscores the need for more standardized diagnostic modalities and prompt recognition and treatment of these rare but serious syndromes.

An Atypical Presentation of Sarcoid Myositis.

Sarcoidosis is a well-characterized inflammatory disease that affects multiple organ systems and can have long-term devastating outcomes if not identified and treated appropriately. The disease is most prevalent among young to middle-aged African American women. It most commonly presents with pulmonary involvement, though there are reported cases of sarcoidosis without pulmonary involvement. Pulmonary presentations can be biopsied, diagnosed, and treated with primary immunomodulation with great treatment success. Here, we present an unusual presentation of sarcoidosis as granulomatosis mucositis in the salivary gland and concurrent rare complication of sarcoid myositis in the rectus femoris in a patient with no evidence of pulmonary involvement throughout the duration of their clinical course. Further, we discuss differential diagnoses related to this patient's presentation as well as the efficacy of treatment modalities available in the management of this disease.
