Context: Cancer afflicts almost all communities worldwide. Although it arises de novo in many instances, a significant proportion of oral squamous cell carcinoma (OSCC) develops from potentially malignant disorders (PMDs). Further, the association of Candida with various potentially malignant and malignant lesions has been reported as a causative agent. Aims: The aim of the study is to evaluate and intercompare the predominant candidal species among individuals with PMD and OSCC. Subjects and Methods: The swab samples were collected for the microbiological culture followed by incisional biopsy for histopathological confirmation. The swab samples were streaked and incubated on Sabouraud-dextrose agar medium and positive candidal colonies were incubated on CHROM agar for speciation. Settings and Design: A total of clinically diagnosed 95 subjects of which 25 as normal controls, 30 as PMDs and 40 as OSCC were included. The collected swab samples were initially streaked and incubated on Sabouraud dextrose agar (SDA) medium, and later, only positive candidal colonies were incubated on CHROM agar for speciation. Statistical Analysis: Chi-square test was utilized. Results: Positive candidal growth on SDA medium was seen in 24%, 43% and 82% and negative in 76%, 57% and 18% individuals of normal controls, PMDs and OSCC, respectively. On evaluation on Chromagar medium, Candida species was present in 20%, 40% and 77% and absent in 80%, 60% and 23% individuals among controls, PMDs and OSCC group, respectively. On speciation of Candida in CHROMagar among the controls, PMDs and OSCC, Candida albicans species was present in 4 (16%), 7 (23%) and 4 (10%); Candida krusei in 1 (4%), 5 (17%) and 10 (25%); Candida glabrata in nil, nil and 6 (20%) and Candida tropicalis in nil, nil, and 2 (5%) cases, respectively. Conclusion: There was predominant carriage of candidal species in PMDs and OSCC, but whether Candida has specific establishment in PMDs or in malignancy is still a matter of debate.
