Objective: This time, we studied the expression of type II collagen and BMP in a large number of cases of pilomatricoma and extended our study to cutaneous mixed tumor (CMT). Results: WefoundtypeIIcollagendepositionintheoverlyingDEJ(16of 50 cases) and in the SCs (19/50) of pilomatricoma. The number of case of type II collagen deposition in DEJ(DEJ+ )and in SCs (SC+ ) of pilomatricoma correlated to the chronological stage of pilomatricoma. We also found type II collagen deposition in overlying DEJ (two of 11) and in the stromal chondroid tissue (four of 11) of CMT. BMP 2 was expressed in most cases of pilomatricoma (37/50) and CMT (seven of 11). Conclusions: The expression of type II collagen in pilomatricoma is dependent upon the chronological stage of pilomatricoma. Type II collagen expression in the overlying DEJ and chondroid matrix in CMT may be induced by BMP via the same mechanism as in pilomatricoma.展开更多

Treatment with tacrolimus ointment 0.1 % resulted in the rapid improvement of each recurred lesion and allowed withdr awal of indomethacin. To our knowledge, this is the first report of the use of t opical tacrolimus in the treatment of eosinophilic pustular folliculitis.

(S74-S76) Abstract:We describe the case of a 64- year-old man with a cutaneous carcin oid tumo r. Clinical investigation and diagnostic studies failed to reveal an internal pr imary tumor. Five cases of primary cutaneous carcinoid tumor have been reported in the literature. Interestingly, our patient had coexisting lichen planus, whic h has been reported previously in association with carcinoid.展开更多
