A case of Maffucci's syndrome is reported in a 6-year-old girl. She had multiple enchondromas of the long bones and the phalangeal bones with hemangiomatous skin lesions. The hemangiomas were the capillary type and were not anatomically related to the bone lesions.

Kaposis sarcoma(KS) is a multicentrically developing vascular neoplasm with four types of clinical manifestation. One of these, classic KS is clinically carmcterized by late onset, chronic course and radiosensitive. We report a case of classic KS in a 72-year-old male. This pateint complainted of purple patches and dark purple nxluk. on slightly edematous lower legs. The histopathologic sections from the lesional sites showed infiltration of spindle cells with newly formed vascular slits, dilated blood vessels and aggregated hemosiderins in the dermis.

Wolf-Hirschhorn syndrome (WHS) is a malformation associated with a hemizygous deletion of the distal short arm of chromosome 4. Herein we report a fetal autopsy case of WHS. A male fetus was therapeutically aborted at 17(+0) weeks gestational age, due to complex anomaly and intrauterine growth retardation, which were found in prenatal ultrasonography. His birth weight was 65 g. Mild craniofacial dysmorphism, club feet, bilateral renal hypoplasia, edematous neck, and left diaphragmatic hernia of Bochdalek were found on gross examination. On GTG-banding, the fetus revealed 46,XY,add(4p) karyotype and the mother revealed 46,XX,t(4;18)(p16;q21.1), with normal karyotype of the father. Array comparative genomic hybridization performed on the autopsied lung tissue revealed loss of 4p16.2-->4pter and gain of 18q21.1-->18qter, suggesting 46,XY,der(4)t(4;18)(p16.2;q21.1)mat of fetal karyotype. This suggested deletion of 4p, compatible with WHS inherited from the mal-segregation of a maternal translocation t(4;18)(p16.2;21.1). Therefore, our fetus was both genotypically and phenotypically compatible with WHS.

The use of a cultured autologous keratinocyte sheet has become a recognized method for the coverage of extensive bums during recent years. The disadvantages of these sheet grafts are a long time-lag until keratinocyte sheets are available, the fragility and difficulty in handling of grafts, an unpredictable take rate and extremely high costs. In this study we investigated the transplantation of cultured keratinocytes as single cells suspended in autologous fibrin glue. In a rat model with standardized full thickness wounds, this new transplantation technique was evaluated and compared directly to the conventional keratinocyte sheet grafting technique. After transplantation, wounds were evaluated for the degree of epithelial coverage, and then microscopic structures were evaluated under light and electron microscopy. The results were as follows: 1) The fibrinogen solution prepared from autologous blood had 12 times more fibrinogen compared to the original blood. 2) After transplantation of cultured keratinocyt-es in fibrin glue, the degree of epithelial coverage was 79% at 2 weeks, which was comparable to 17% for cultured keratinocyte sheet graft 3) Typical basement membrane structures were consistently found at 2 weeks after transplantation of keratinocytes in fibrin glue. 4) Rete ridges were found at 4 weeks after transplantation of keratinocytes in fibrin glue. In conclusion, the transplantation technique of keratinocytes in fibrin glue is available earlier than sheet grafts, it transfers actively proliferating cells and it simplifies the grafting procedure. As well, this technique leads to an earlier epithelial covering and an earlier restoration of the dermo-epidermal junction than sheet grafting.
