Cryptococcal parotitis presenting as a cystic parotid mass: Report of a case diagnosed by fine-needle aspiration cytology

Candida Infection Associated with Salivary Gland-A Narrative Review

Candida species are common global opportunistic pathogens that could repeatedly and chronically cause oral mucosa infection and create an inflammatory environment, leading to organ dysfunction. Oral Candida infections may cause temporary or permanent damage to salivary glands, resulting in the destruction of acinar cells and the formation of scar tissue. Restricted function of the salivary glands leads to discomfort and diseases of the oral mucosa, such as dry mouth and associated infection. This narrative review attempts to summarize the anatomy and function of salivary glands, the associations between Candida and saliva, the effects of Candida infection on salivary glands, and the treatment strategies. Overall, clinicians should proactively manage Candida infections by educating patients on oral hygiene management for vulnerable populations, conducting frequent checks for a timely diagnosis, and providing an effective treatment plan.

Cryptococcus: A Rare Cause of Parotid Abscess in Liver Cirrhosis

A 61-year-old man with decompensated liver cirrhosis presented with a parotid mass. Fine-needle aspiration of the parotid gland revealed Cryptococcus neoformans. Lumbar puncture confirmed cryptococcal meningitis. Multiple splenic lesions with radiographic features consistent with cryptococcal splenic abscesses were also seen. Despite antifungal therapy, the patient died 17 days after infection was confirmed. This is the first report of a cryptococcal parotid abscess in a patient with liver cirrhosis.

Review of HIV-Related Cytopathology

Exfoliative and aspiration cytologies play a major role in the management of patients with human immunodeficiency virus infection. Common cytology samples include cervicovaginal and anal Papanicolaou tests, fine needle aspirations, respiratory specimens, body fluids, Tzanck preparations, and touch preparations from brain specimens. While the cytopathologists need to be aware of specific infections and neoplasms likely to be encountered in this setting, they should be aware of the current shift in the pattern of human immunodeficiency virus-related diseases, as human immunodeficiency virus patients are living longer with highly active antiretroviral therapy and suffering fewer opportunistic infections with better antimicrobial prophylaxis. There is a rise in nonhuman immunodeficiency virus-defining cancers (e.g., anal cancer, Hodgkin's lymphoma) and entities (e.g., gynecomastia) from drug-related side effects. Given that fine needle aspiration is a valuable, noninvasive, and cost-effective tool, it is frequently employed in the evaluation and diagnosis of human immunodeficiency virus-related diseases. Anal Papanicolaou tests are also increasing as a result of enhanced screening of human immunodeficiency virus-positive patients for cancer. This paper covers the broad spectrum of disease entities likely to be encountered with human immunodeficiency virus-related cytopathology.

Oral manifestations after immune reconstitution in HIV patients on HAART

In order to verify possible association between immune reconstitution inflammatory syndrome (IRIS) and oral manifestations (OMs), we selected AIDS patients who had low CD4 count before the initiation of highly active antiretroviral therapy (HAART) and who returned three months later for therapy evaluation. The oral lesions observed three months after the initiation of HAART were evaluated and associated with the type of antiretroviral therapy (ART), CD4 count and HIV-RNA load levels (before and three months after HAART initiation). A total of 105 patients matched the selected criteria. Immune reconstitution (IR) was identified in 35.2%. Among these patients, the mean CD4 cell count rose from 105.97 to 330.29 and the mean viral load dropped from 168.005 (log 5.22) to 21.852 (log 4.33). There was no significant difference in age (P = 0.78), sex (P = 0.41) or previous history of ART (P = 0.55) between IR and non-IR patients. In the IR group, the most common OM was parotid enlargement (57.14%) (P = 0.019), whereas in the non-IR group candidiasis (46.15%) was the most common OM. The results of our study suggest that the parotid gland enlargement found in the studied population might be an IRIS event, as it was found in patients with IR three months after the initiation of HAART.

Parotid gland fine-needle aspiration cytology: An approach to differential diagnosis

Parotid glands can undergo a wide range of pathologic changes that may be difficult to characterize by clinical features alone. No single diagnostic modality is currently accepted unequivocally as the definitive approach to parotid gland enlargement or tumors. Although it is generally accepted that fine-needle aspiration (FNA) biopsy is useful in the preoperative setting, the accuracy is highly dependent on both operator experience and the interpretative skills of the cytopathologist. Results of FNA biopsy must be considered in a global context, in conjunction with clinical and radiographic findings. The objectives of this paper are threefold: (1) to define the clinical role of parotid FNA, such that pathologists performing and/or interpreting such specimens have a clearer understanding of the expectations of our surgical colleagues; (2) to clearly describe a protocol for the performance of parotid FNA biopsy, including a discussion of complications and pitfalls; and (3) to present the cytologic differential diagnoses of diverse clinicopathologic parotid gland processes that may present as generalized enlargement, cystic lesions, or discrete masses.
