Digital mucinous pseudocysts are commonly seen in rheumatology practice, but the most pertinent literature is found in nonrheumatology publications. These lesions are commonly located on the finger near the nail, where they can be associated with a linear atrophic nail defect (Figure 1).

In the course of investigations (Goldman, et at., Rockwell ci at., in press) on the mechanisms of the bites of various arthropods in the skin of man, histo.. pathologic study of the area of the bite was found to be an important part of the work. The clinical reaction to such a bite can be characterized usually as a local ized area exhibiting redness, swelling, heat, itching and pain in varying degrees of intensity. Since these are the classical clinical concomitants of tissue response to injuryi.e. inflammation,itisperhaps not too surprising that the histologyof this inflammatory reaction has been taken for granted and that few specific studiesrelating to earlyinsectbitereactions areavailable in the literature (Brown et at.
