An 83-year-old woman was referred to the Dermatology department with a papular eruption on her left arm, occurring below the scar site of a malignant melanoma in situ, which had been excised 6 months previously. On physical examination, multiple, tender, violaceous papules and nodules inferior to the scar were noted, with central pustules in some of the lesions.

The influence of an inert diluent on the extractability of tetradecyltrimethyl-, tetradecyl-triethyl-, decyltriethyl- and tetra-amylammonium bromides into 1,2-dichloroethane + n-alkane mixtures at 25 degrees has been determined. On the basis of the experimental data it is suggested that the bromide moiety of the ion-pair is solvated in the organic phase by 5-6 molecules of 1,2-dichloroethane.
