Insights
A rare case of plasmablastic lymphoma (PBL), an aggressive non-Hodgkin lymphoma (NHL), was diagnosed in an HIV/AIDS patient with a skin mass. This highlights challenges in treating this malignancy and controlling HIV disease.
Area of Science:
- Oncology
- Infectious Diseases
- Immunology
Background:
- Plasmablastic lymphoma (PBL) is a rare and aggressive non-Hodgkin lymphoma (NHL) predominantly affecting HIV-positive individuals.
- PBL in HIV patients is associated with low CD4 counts, high viral loads, and chronic infection.
- Extraoral PBL is exceptionally rare, with limited case reports in medical literature.
Purpose of the Study:
- To report a case of cutaneous plasmablastic lymphoma in an HIV/AIDS patient.
- To discuss the diagnostic challenges and treatment outcomes for PBL in the context of HIV infection.
- To explore potential associations between chronic inflammation from Cryptococcus and PBL development.
Main Methods:
- Case presentation of an HIV/AIDS patient with a cutaneous mass.
- Biopsy and histopathological examination to diagnose plasmablastic lymphoma.
- Review of relevant literature on PBL in HIV-positive individuals.
Main Results:
- The patient was diagnosed with cutaneous plasmablastic lymphoma (PBL) over a site of prior cryptococcal infection.
- PBL is an aggressive malignancy in HIV-positive individuals, often presenting in middle-aged males with compromised immune status.
- Standard chemotherapy regimens like CHOP show limited efficacy, with poor overall survival rates.
Conclusions:
- Improving clinical outcomes for PBL in HIV patients remains a significant challenge.
- Effective antiretroviral therapy and HIV disease control are crucial for managing this malignancy.
- A chronic inflammatory state, such as that caused by disseminated Cryptococcus, may play a role in tumorigenesis in PBL patients.
Abstract:
We present a case of a patient with HIV/AIDS who presented with a tender left lower extremity cutaneous mass over a site of previous cryptococcal infection and was found to have plasmablastic lymphoma (PBL). The incidence of PBL is estimated to account for less than 5% of all cases of non-Hodgkin lymphoma (NHL) in HIV-positive individuals. In fact, there were only two reports of extraoral PBL at the time of a 2003 review. PBL in HIV-positive individuals is an aggressive malignancy that tends to occur in middle-aged males with low CD4 counts, high viral loads, and chronic HIV infection. The definitive diagnosis can be made with biopsy which typically shows malignant lymphoid cells that stain positive for plasma cell markers and negative for B-cell markers. The most common treatment is chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like regimens, but the overall survival rate is poor despite its relative responsiveness to chemotherapy. This case highlights the challenges that remain in improving clinical outcomes, the importance of antiretroviral therapy and HIV disease control, and a potential association between a chronic inflammatory state caused by disseminated Cryptococcus and tumorigenesis in individuals with PBL.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
