Two types of new chitin dressings, mesh reinforcement type and sponge-sheet type, were manufactured and applied to skin wounds such as burns and donor sites. The advantages include pain relief, wound hemostasis, adherence and drying. In comparison to the regular type of chitin, the new dressings show no autolysis or breaking and have possibilities for long-term use in wound with extensive exudate. No side effects were observed. Key words: Chitin-Wound dressing -Local therapy of burn Donor site As research in cultured skin is moving towards clinical realization, wound dressings are moving from protection of the skin defect to a synthetic cover which will replace skin.The excellent properties of regular chitin dressing, namely its good pain relief, adherence and drying effect, have been presented previously [6]. The current study Fig. 1. New chitin non-woven fabric, mesh-reinforcement type of Fig. 2 a, b. Chitin sponge sheet (a) and electron micrograph (b) 10 x 10 cm of chitin sponge ( x 50)

A 58-year-old man developed 3 indurative erythematous lesions like necrobiosis lipoidica on the right lower leg. He had had similar cutaneous lesions 1.5 years previously. These had been surgically excised, and a histologic diagnosis of necrobiosis lipoidica was made at another hospital. He was diagnosed as having lymphomatoid granulomatosis by lung biopsy in our hospital. Nasal involvement was confirmed in later examinations and the skin lesions were also considered to be the cutaneous manifestation of lymphomatoid granulomatosis. This outlines that cutaneous manifestations may allow early diagnosis of lymphomatoid granulomatosis.
