The influence of immune status, age, and sex on Majocchi granuloma: a review of 52 cases from a tertiary level hospital and published Korean cases in literature.

BACKGROUND: Majocchi granuloma (MG) is a rare dermal and subcutaneous granulomatous inflammation caused by dermatophytes. The detailed characteristics of MG are not fully elucidated. This study investigated the influence of systemic immune status, age, and sex on the clinical, demographic, mycological, and therapeutic characteristics of MG in Korea.

METHODS: We analyzed cases of histopathologically diagnosed MG at our tertiary referral center from January 2001 to December 2016. We also analyzed all Korean MG cases published in Korean and English literature to date. The different features based on immune status, age, and sex were compared. P < 0.05 were considered statistically significant.

RESULTS: We enrolled 52 patients, 33 (63.5%) were male and 19 (36.5%) were female. The mean age was 45.4 ± 23.1 years. Immunosuppression was reported in 13 cases (26.5%). Statistical analysis showed that the immune status affects the anatomical location and clinical manifestation. Age has an influence on involved sites and identified fungal species. The frequent fungal pathogens were different based on sex.

CONCLUSION: The results of our study revealed that distinctive features of MG exist based on immune status, age, and sex.
