ready documented. As reported in his book, Dr. Mohs 1 treated five BCCs of the scrotum, yielding an overall incidence of 0.065% (N = 7674).We believe that there is a greater risk of metastatic BCC when the primary BCC is located on the scrotum.

To the Editor." I read with interest the recent article on mid-dermal elastolysis by Kim and Su (J AM AeAD DERMATOL1992;26:169-73). I was surprised to note that an article of mine (published in early 1990) documenting two "classic" cases of mid-dermal elastolysis was not ineluded in their extensive bibliography.1 Since the "accepted for publication" date for Dr. Kim's article was July 1991, I daresay that there was plenty of time during revision and "galley proofing" of their article for the two cases I reported to have been added to this "review of the literature."
Biology of cutaneous squamous cell carcinoma To the Editor: The recent review of squamous cell carcinoma (SCC) by Kwa et al. (J AM ACAD DERMATOL 1992;26:1-26) is comprehensive and well researched. In general, it provides insight into the biologic behavior and treatment of this tumor. However, we take exception with the generally negative comments presented concerning the use of photodynamic therapy (PDT) in the treatment of cutaneous SCC. A study in which one of us (M. W.) participated was used to support the overall position that PDT shows little potential as a therapeutic modality for SCC. 1It should be known that the poor results of this particular study could be attributed to the use of too low laser energy density and that other investigators have had considerably more encouraging results in the treatment of SCC with PDT. 2, 3 Such studies, 2, 3 as well as single case reports4 in which PDT was used to treat in situ and invasive SCC, have yielded, good results. Indeed, we have learned from our earlier experiences with PDT. David J.

Reply To the Editor." When we first searched the literature, the excellent article by Dr. Rudolph on mid-dermal elastolysis had not appeared. We became aware of this article after we submitted our paper to the JOURNAL. W e intended to include Dr. Rudolph's paper at the galleyproof stage but forgot to do so. it was our mistake, and we apologize for it. ,long Min Kim, MD, and W.. P.
