Unsuspected Malaria Diagnosed on a Routine Peripheral Smear Review.

Prompt diagnosis of malaria infection is critical for effective management, yet it can be challenging due to varying incubation periods and the need for physician-initiated laboratory workups. We present a case of a 40-year-old male with fever and dark-colored urine, initially evaluated for sepsis. Plasmodium vivax was incidentally identified on a peripheral smear review after obtaining a remote travel history from a malaria-endemic area.

Undiagnosed Metastatic Breast Carcinoma Presenting as Thrombotic Thrombocytopenic Purpura.

Cancer-associated thrombotic microangiopathy has a documented relationship with metastatic disease. Other examples of thrombotic microangiopathy (TMA) include thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). All these conditions can present with microangiopathic hemolytic anemia as well as thrombocytopenia.

Concurrent Splenic Marginal Zone B Cell Lymphoma and Metastatic Pancreatic Adenocarcinoma Diagnosed on Splenectomy for Suspected Splenic Abscess.

Splenic marginal zone lymphoma (SMZL) is an uncommon low-grade B-cell lymphoma. It is an indolent lymphoma with a median survival rate of greater than 10 years. Most patients are asymptomatic, but some patients may present with upper abdominal pain and distention, while others may present with splenomegaly, emaciation, fatigue, or weight loss.

Cotyledonoid Dissecting Leiomyoma: A Rare Variant of Leiomyoma of the Uterus.

Cotyledonoid dissecting leiomyoma is a rare variant of leiomyoma and has only been reported a few times in the literature. As a result of its alarming gross and radiologic appearance, it must be differentiated from other malignant smooth muscle tumors. We report a case of cotyledonoid dissecting leiomyoma in an African American premenopausal woman with a medical history of anemia, abnormal uterine bleeding, and a cervical mass.

Multiple Primary Malignant Neoplasms in African Americans: A Case Series and Literature Review.

Multiple primary malignant neoplasms (MPMNs) or multiple primary malignancies are defined as two or more histologically distinct malignancies present in the same individual. While second or higher-order malignancies account for approximately 18% of all cancers in the United States, it is reasonable to presume that MPMNs are now occurring more frequently than previously reported. Underserved groups such as blacks and Hispanics may represent a high proportion of these underreported cases due to well-established health disparities.
