Cytophotometric studies of epidermal proliferation in psoriatic and normal skin.
Cytophotometric measurements of single-cell DNA content were used to study human epidermal cell proliferation in vivo. It was found that Feulgen-DNA profiles can be used to assess proliferative activity in involved, uninvolved, and nonpsoriatic skin. Profiles of involved psoriatic skin were bimodal as is characteristic of actively proliferating populations. This was due to the presence of cells with twice (2C--presynthetic) or four times (4C--post-synthetic) the amount of DNA of the gametes, separated by the intermediate values of cells undergoing scheduled DNA synthesis. Profiles of uninvolved psoriatic as well as nonpsoriatic epidermis were unimodal with the majority of cells containing a 2C amount of DNA incating relatively low levels of proliferative activity. The observed variations in proliferative activity of these samples are discussed in terms of two alternative models. Since radioisotopes are not required, this technique presents a useful approach to studying human epidermal proliferation in vivo.
Pseudopelade of Brocq secondary to lichen planus.
Immunofluorescence studies as as the underlying cause of pseudopelade of Brocq (PPOB) in a middle-aged woman. The routine use of immunofluorescent studies in clinical cases of pseudopelade of Brocq might make more specific diagnoses possible.

Unilateral nevoid telangiectasia with gastric involvement.
A 49-year-old man with liver disease developed a unilateral telangiectatic lesion over the left trigeminal and left C3, C4, C5, and T1 dermatomal areas. This case fulfills the criteria for unilateral nervoid telangiectatic syndrome (UNTS), and as such represents the 11th reported case of UNTS and the first case, to our knowledge, of visceral involvement associated with a similar vascular malformation. A hemorrhagic tendency is present in this syndrome when there is gastrointestinal involvement.
