Exposure to formaldehyde is one of the various occupational hazards experienced by a doctor. It is used in its aqueous form, formalin for embalming cadavers which are used for teaching gross anatomy by dissection. Therefore, medical students in their first year routinely handle the cadaver and dermal contact is thus a significant and consistent portal of exposure to formaldehyde. The toxic and allergic potential of formaldehyde is well documented in research literature. The present study was intended to assess the various dermatological manifestations of this exposure and provide a possible understanding of the mechanism behind it by estimation of eosinophil count. Descriptive statistics, Friedman’s Test and paired-t test were used for statistical analysis. A p-value < 0.05 was considered significant. The study revealed that dermal symptoms persist late and start to decline by six months onwards. A rise in absolute eosinophil count was also noted. The study highlights the role of formaldehyde as an occupational hazard and suggests a possible allergic mechanism behind these symptoms. Therefore, we should encourage use of protective gloves and other options available to reduce exposure.
