[Cutaneous malignancies in occupationally-induced scars]

The occurrence of neoplasms in injury scars--as consequence of occupational accidents--may lead to compensation according to the statutory accident insurance regulations. According to newer regulatory attempts in occupational dermatology, certain criteria have to be met before the diagnosis of a neoplasm induced by a scar is accepted and compensation is due.

Based on a retrospective analysis of 217 dermatological claim files between 2007 and 2009 of the IPA (including 22 follow-ups), medical opinions on neoplasms developing in possible occupational scars were re-evaluated using criteria of the German social accident insurance and the Bamberg medical bulletin, part II (Bamberger Merkblatt, BM II) to see how well they qualified for recognition as an occupational or accident-related disorder.

Three cases were identified where a neoplasm was suspected of having developed in an occupationally-related scar. One of the insured events entitled for compensation. Following the guidelines of the BM II, this case was approved as an occupational disease secondary to injuries with resultant reduction in earning capacity, whereas the others did not meet the requirements.

Two problems in evaluating malignant tumors in occupational scars are the long latency period and the documentation of a scar. The tumor excision specimen should be histologically re-examined to document the presence of an associated scar.
