Have you ever seen a pathologist with acne vulgaris?

Acne vulgaris (AV) is an inflammatory disease of pilosebaceous unit ocuring frequently in adolescences. The most important factors association with the pathogenesis of AV are folicular keratinization, androgens, increased sebum production and Propionibacterium acnes. In addition, emotional stress, drugs, cosmetics, and mechanical factors may trigger it. AV has such findings as comedon, papulopustule, nodule and cyst. Various treatment options modifying its etiopathogenic processes acording to its severity are present. Formalin is 40% diluted solition of formaldehyde. In pathology, most commonly 10% formalin (i.e. 4% formaldehyde) is used for the fixation of micro-anotomy of the living tissue1. In this latter, an interesting experience of an pathology resident whose acne complaints improved after short term exposure to formaldehyde vapor is shared.
