Each of these patterns follows a distinctive linear expression that is most clearly visualized on the back. We report a new linear pattern observed in this location consisting of clinically and histologically proven seborrheic keratoses on the backs of elderly patients that follows what appears to be a linear, splayed, vertical distribution that we term a raindrop pattern.

Observations

In a series of 100 consecutive patients seen at the Veterans Affairs Palo Alto Health Care System, Palo Alto, Calif, 7 patients were found to have a linear, splayed, vertical pattern of lesions on their backs (Figure 1). These lesions were clinically diagnosed as seborrheic keratoses, and the diagnosis was confirmed on histologic examination. The mean . . . [Full Text of this Article]
