We report a case of acral pigmented lesions due to pine tar, a common compound used on baseball bats to improve grip, deposition. The patient presented with an acute concern for a new melanocytic lesion, and dermoscopy revealed large brown globules, not typical of melanocytic neoplasms. We propose that the coupling of dermoscopy and a thorough clinical history of exogenous exposures in similar clinical presentations can provide reassurance in evaluating atypical appearing pigmented lesions.
