Background: Microcystic adnexal carcinoma, or sclerosing sweat duct carcinoma, is an uncommon cutaneous neoplasm associated with extensive local invasion. The standard of care with regard to the best excisional method in treating microcystic adnexal carcinoma has not been established.Objectives: To perform a retrospective study comparing patients treated by Mohs micrographic surgery with those treated by wide excision and to elucidate the epidemiological features of microcystic adnexal carcinoma. Patients and Methods:A retrospective analysis of a case series involving 48 primary and referral patients diagnosed as having microcystic adnexal carcinoma using standardized criteria. All cases were reviewed by the same dermatopathologists.Results: Microcystic adnexal carcinoma predominantly affects the left side of the face of middle-aged women. Microcystic adnexal carcinoma is misdiag-

The quantity of fungal DNA in the middle meatus did not differ in patients with and without chronic rhinosinusitis and was not correlated with quality of life outcomes. Therefore, the quantity of fungi does not explain pathogenicity in patients with chronic rhinosinusitis. However, because of small sample size, the study must be replicated in a larger patient population.

Bariatric surgery as a means of treating SAS in the morbidly obese provides effective long-term reduction in RDI. Bariatric surgery also significantly improves minimum oxygen saturation in morbidly obese patients with SAS. Biliopancreatic bypass is more effective in reducing RDI to normal values than vertical banded gastroplasty.
